Auto Loan Calculator
| Rate | Monthly Payment | Total Interest | vs Base Rate |
|---|
An auto loan calculator is the fastest way to determine exactly how much a car will cost before you walk into a dealership. A vehicle priced at $32,000 with a 7.5% APR over 60 months produces a monthly payment of $641 — but the same vehicle financed over 72 months at 8.9% costs $586 per month while generating $10,192 in total interest. Understanding these trade-offs before signing a financing agreement can save a buyer thousands of dollars.
This free Auto Loan Calculator computes your monthly payment, total interest paid, total loan cost, and full amortization schedule in seconds. Enter your vehicle price, down payment, trade-in value, loan term, and interest rate — the calculator handles the rest. No sign-up required.
Auto Loan Calculator — Definition: An auto loan calculator computes the monthly payment amount, total interest paid, and total cost of financing a vehicle purchase based on the loan amount, annual percentage rate (APR), and loan term in months. It applies the standard amortization formula to generate a complete payment schedule showing the principal and interest breakdown for every payment.
What Is an Auto Loan?
Auto Loan Definition
An auto loan is a secured installment loan used to finance the purchase of a new or used vehicle. The vehicle itself serves as collateral — meaning the lender holds a lien on the title until the loan is fully repaid. If the borrower defaults, the lender has the legal right to repossess the vehicle to recover the outstanding balance.
Auto loans are amortizing loans — each monthly payment covers both accrued interest and a portion of the principal balance. In early payments, the majority of each installment goes toward interest. As the balance decreases, a growing share of each payment reduces the principal. This is the standard loan amortization structure applied by every auto lender.
Auto Loan vs. Personal Loan — Key Difference
| Feature | Auto Loan | Personal Loan |
| Collateral | Vehicle (secured) | None (unsecured) |
| Typical APR Range | 4% – 15% (varies by credit) | 8% – 36% (varies by credit) |
| Loan Term | 24 – 84 months | 12 – 60 months |
| Approval Speed | Same day at dealership or bank | 1 – 3 business days |
| Usage Restriction | Vehicle purchase only | Any purpose |
| Lender Holds Title | Yes — until paid off | No title involved |
| Best For | Vehicle financing (lower rate) | Buyers wanting no lien on vehicle |
Auto Loan Formula
The Standard Monthly Payment Formula
The monthly auto loan payment is calculated using the standard loan amortization formula:
M = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1]
Where:
- M = Monthly payment amount
- P = Principal loan amount (vehicle price minus down payment and trade-in value)
- r = Monthly interest rate = Annual Percentage Rate (APR) ÷ 12
- n = Total number of monthly payments = Loan term in years × 12
Total Interest Paid Formula
Total Interest = (Monthly Payment × Number of Payments) − Principal
Total interest reveals the true cost of financing. A borrower who focuses only on the monthly payment — rather than the total cost — routinely overpays by thousands of dollars by choosing longer loan terms that appear affordable but accumulate significantly more interest over time.
Total Loan Cost Formula
Total Loan Cost = Monthly Payment × Number of Payments
Total loan cost is the complete financial commitment of the auto loan — principal plus all interest payments combined. This figure is the most important number for comparing financing options because it captures the full economic cost of each scenario regardless of the monthly payment amount.
How to Use the Auto Loan Calculator — Step by Step
Step 1 — Enter the Vehicle Price
Enter the full purchase price of the vehicle — the price negotiated with the dealer or seller before any down payment, trade-in, or fees. Use the out-the-door price (vehicle price plus taxes, title, registration, and documentation fees) for the most accurate total cost calculation.
Important: Always negotiate the vehicle price before discussing financing. Dealers often shift negotiation pressure to the monthly payment to obscure the total vehicle cost. Lock in the purchase price first, then evaluate financing separately.
Step 2 — Enter the Down Payment
The down payment is the cash amount paid upfront at the time of purchase. It directly reduces the loan principal — a larger down payment produces a smaller loan balance, lower monthly payments, and significantly less total interest paid over the life of the loan.
The standard recommendation from financial advisors is a minimum down payment of 20% on a new vehicle and 10% on a used vehicle. These thresholds protect buyers from becoming immediately underwater — owing more than the vehicle is worth — which happens instantly with low or zero down payment financing due to immediate vehicle depreciation.
Step 3 — Enter Trade-In Value (If Applicable)
If trading in an existing vehicle, enter its estimated trade-in value. Trade-in value functions identically to a down payment — it reduces the loan principal before interest is calculated. Obtain multiple trade-in quotes from Carmax, Carvana, and the dealership to ensure you are receiving fair market value. Dealerships routinely offer below-market trade-in values to compensate for vehicle price discounts.
Trade-in equity = Trade-in value minus any remaining loan balance on the vehicle being traded. If you owe more than the trade-in is worth (negative equity), that deficit is added to the new loan principal — a practice called rolling over negative equity that significantly increases total borrowing costs.
Step 4 — Enter the Loan Term
Select the loan term in months — the total number of monthly payments. Common auto loan terms are 24, 36, 48, 60, 72, and 84 months (2, 3, 4, 5, 6, and 7 years). The loan term is the single most consequential variable in auto loan cost:
- Shorter terms = higher monthly payments, much less total interest paid, faster equity building
- Longer terms = lower monthly payments, significantly more total interest paid, prolonged negative equity period
The average new car loan term in the United States reached 68 months in 2024 — nearly 6 years — as rising vehicle prices pushed buyers toward longer terms to achieve affordable monthly payments. This trend dramatically increases total interest cost and extends the period during which buyers owe more than their vehicle is worth.
Step 5 — Enter the Annual Percentage Rate (APR)
The APR is the annual interest rate charged on the loan balance, expressed as a percentage. It is the primary cost driver in auto financing — a difference of just 2 percentage points on a $30,000 loan over 60 months generates over $1,700 in additional interest. Always compare APR across lenders, not just monthly payment amounts.
APR is determined primarily by credit score but also by lender type, loan term, vehicle age, and market conditions. Obtain pre-approval from your bank or credit union before visiting a dealership — dealers markup interest rates above the lender’s base rate as additional profit, and pre-approval gives you a known benchmark to compare against dealer financing offers.
Step 6 — Read Your Monthly Payment and Full Amortization Schedule
The calculator returns your monthly payment, total interest paid, and total loan cost. The amortization schedule shows the exact principal and interest breakdown for every payment over the life of the loan — revealing exactly how much of each payment builds equity versus pays the lender’s financing cost.
Auto Loan Example Calculation
Example Vehicle and Financing Scenario
| Input Variable | Value |
| Vehicle Price | $32,000 |
| Down Payment | $6,400 (20%) |
| Trade-In Value | $0 |
| Loan Principal | $25,600 |
| Annual Percentage Rate (APR) | 7.50% |
| Loan Term | 60 months (5 years) |
| Monthly Interest Rate (r) | 0.625% (7.50% ÷ 12) |
Monthly Payment Calculation
M = $25,600 × [0.00625 × (1.00625)⁶⁰] ÷ [(1.00625)⁶⁰ − 1] = $512.82
The monthly payment on this vehicle is $512.82 — payable for 60 consecutive months.
Total Interest and Loan Cost
| Cost Metric | Amount | What It Means |
| Monthly Payment | $512.82 | Fixed payment due every month for 60 months |
| Total Payments | $30,769.20 | Monthly payment × 60 months |
| Total Interest Paid | $5,169.20 | Total payments minus original principal |
| Total Loan Cost | $30,769.20 | Full financial commitment including all interest |
| Effective Cost Per Month (all-in) | $512.82 | Principal + interest blended into fixed payment |
| Interest as % of Principal | 20.2% | Financing premium above vehicle purchase price |
Amortization Schedule — First 6 Payments
| Payment # | Beginning Balance | Monthly Payment | Interest Portion | Principal Portion | Ending Balance |
| 1 | $25,600.00 | $512.82 | $160.00 | $352.82 | $25,247.18 |
| 2 | $25,247.18 | $512.82 | $157.79 | $355.03 | $24,892.15 |
| 3 | $24,892.15 | $512.82 | $155.58 | $357.24 | $24,534.91 |
| 4 | $24,534.91 | $512.82 | $153.34 | $359.48 | $24,175.43 |
| 5 | $24,175.43 | $512.82 | $151.10 | $361.72 | $23,813.71 |
| 6 | $23,813.71 | $512.82 | $148.84 | $363.98 | $23,449.73 |
| … (continues for 60 months) | … | … | … | … | … |
The amortization table demonstrates the front-loading of interest inherent in installment loan structure. In the first payment, $160.00 of the $512.82 goes to interest — 31.2% of the payment. By month 60, the interest portion shrinks to under $3.20 per payment as the remaining balance approaches zero. This is why making extra principal payments early in the loan term generates disproportionately large interest savings.
Loan Term Comparison — How Term Length Changes Total Cost
$25,600 Loan at 7.5% APR — Term Comparison
| Loan Term | Monthly Payment | Total Interest | Total Cost | Interest Premium |
| 24 months (2 years) | $1,153.62 | $1,686.88 | $27,286.88 | 6.6% |
| 36 months (3 years) | $793.17 | $2,554.12 | $28,154.12 | 10.0% |
| 48 months (4 years) | $619.74 | $3,347.52 | $28,947.52 | 13.1% |
| 60 months (5 years) | $512.82 | $5,169.20 | $30,769.20 | 20.2% |
| 72 months (6 years) | $440.93 | $7,347.00 | $32,947.00 | 28.7% |
| 84 months (7 years) | $389.98 | $9,798.32 | $35,398.32 | 38.3% |
Key insight: Extending the loan from 60 months to 84 months reduces the monthly payment by $122.84 — but adds $4,629.12 in total interest. The buyer who chooses 84 months over 60 months to afford a lower payment pays 38.3% above the principal price in total financing costs — nearly $10,000 in interest alone on a $25,600 loan.
APR Comparison — How Your Credit Score Changes Auto Loan Cost
Credit Score Impact on Auto Loan APR
Credit score is the primary determinant of auto loan APR. Lenders use credit-based pricing — borrowers with higher credit scores receive lower interest rates because they represent lower default risk. The spread between the best and worst credit tiers on a typical auto loan is 15 to 20 percentage points — a difference that can generate tens of thousands of dollars in additional interest cost over the life of the loan.
| Credit Score Range | Credit Tier | Typical New Car APR | Typical Used Car APR | Monthly Payment on $25K/60mo |
| 781 – 850 | Super Prime | 4.50% – 6.00% | 5.50% – 7.50% | $466 – $482 |
| 661 – 780 | Prime | 6.00% – 8.50% | 7.50% – 10.50% | $482 – $513 |
| 601 – 660 | Near Prime | 8.50% – 12.00% | 10.50% – 15.00% | $513 – $556 |
| 501 – 600 | Subprime | 12.00% – 18.00% | 15.00% – 22.00% | $556 – $634 |
| 300 – 500 | Deep Subprime | 18.00% – 25.00%+ | 22.00% – 29.00%+ | $634 – $741+ |
A borrower with a 780 credit score financing $25,000 over 60 months at 6.0% pays $483 per month and $3,980 in total interest. The same borrower with a 550 credit score financing the same loan at 18.0% pays $634 per month and $13,040 in total interest — $9,060 more for the identical vehicle. This is why improving credit score before applying for an auto loan is one of the highest-return financial actions a car buyer can take.
What Is a Good APR for an Auto Loan?
Good Auto Loan APR by Vehicle Type and Credit Score
A good APR for an auto loan is defined relative to current market rates and the borrower’s credit profile. As of 2024 and 2025, average auto loan rates across credit tiers range from approximately 5% for prime borrowers on new vehicles to 21%+ for deep subprime borrowers on used vehicles.
| Scenario | Good APR Benchmark | Excellent APR Benchmark |
| New car — excellent credit (750+) | Below 6.5% | Below 5.0% |
| New car — good credit (700–749) | Below 8.5% | Below 7.0% |
| New car — fair credit (650–699) | Below 12.0% | Below 10.0% |
| Used car — excellent credit (750+) | Below 8.0% | Below 6.5% |
| Used car — good credit (700–749) | Below 10.5% | Below 8.5% |
| Used car — fair credit (650–699) | Below 15.0% | Below 12.0% |
The most effective way to secure a good APR is to obtain pre-approval from multiple lenders — your primary bank, a credit union, and at least one online auto lender — before visiting the dealership. Pre-approved buyers know their qualifying rate and can evaluate dealer financing against a concrete alternative rather than accepting the dealer’s first offer.
Where to Get an Auto Loan — Lender Comparison
Types of Auto Loan Lenders
| Lender Type | Typical APR Advantage | Best For | Application Process |
| Credit Unions | 0.5% – 2.0% below banks | Members seeking lowest rates | In-branch or online, member required |
| Banks (national) | Market-rate, competitive | Existing customers, convenience | Online or branch pre-approval |
| Online Lenders | Competitive, fast decision | Rate shopping, convenience | 100% online, instant decision |
| Dealership Financing | Varies — often marked up 1%–3% | Convenience, manufacturer incentives | In-showroom, same day |
| Manufacturer Finance Arms | Promotional 0% – 2.9% (qualified) | New car buyers with excellent credit | Through dealership, credit score dependent |
| Community Banks | Often below national bank rates | Local buyers, relationship banking | Branch-based, may lack online tools |
Dealer Financing vs. Direct Lending — The Rate Markup
Dealers do not lend money directly — they act as intermediaries who submit loan applications to banks and finance companies. The lender approves a base rate (called the buy rate), and the dealer is permitted to markup that rate — typically by 1% to 3% — as additional dealer profit called the dealer reserve or finance reserve. This markup is legal and standard practice but is rarely disclosed to buyers.
A buyer pre-approved by their credit union at 6.5% APR who accepts dealer financing at 8.5% APR on a $30,000 loan over 60 months pays an additional $1,754 in interest above what they would have paid with their own financing. The pre-approval is the most effective tool to prevent this markup — dealers often match or beat external financing offers when they know the buyer has alternatives.
Auto Loan Tips — How to Get the Best Deal
Tip 1 — Get Pre-Approved Before You Visit the Dealership
Pre-approval from a bank or credit union establishes your maximum loan amount and qualifying interest rate before you begin shopping. This transforms the dealership visit from a negotiation where the dealer controls financing information into one where you have a concrete benchmark. Pre-approval is free, does not require a vehicle selection, and typically takes 24 to 48 hours. Most lenders allow pre-approvals to remain valid for 30 to 60 days.
Tip 2 — Negotiate the Vehicle Price, Not the Monthly Payment
Dealers are trained to shift negotiation focus to the monthly payment because payment-based negotiation obscures the vehicle’s total cost. A dealer can reduce your monthly payment by extending your loan term — making a $5,000 overpriced vehicle appear affordable — without reducing the vehicle price at all. Always negotiate the out-the-door vehicle price first and treat financing as a completely separate conversation.
Tip 3 — Choose the Shortest Term You Can Comfortably Afford
Every additional month of loan term generates additional interest and extends the period in which you owe more than the vehicle is worth. As a practical guideline, financial planners recommend that a new vehicle monthly payment not exceed 15% of monthly take-home pay, and that buyers avoid loan terms exceeding 60 months. If the payment on a 48-month or 60-month loan is unaffordable, the vehicle is above your budget — not a signal to extend the term.
Tip 4 — Make a Down Payment of at Least 20%
A 20% down payment on a new vehicle provides immediate protection against negative equity — the situation in which you owe more than the car is worth. New vehicles depreciate approximately 15% to 25% in the first year of ownership. A buyer who finances 100% of a $35,000 vehicle at purchase may owe $32,000 after one year while the vehicle is worth only $27,000 — leaving them $5,000 underwater. A 20% down payment of $7,000 creates an immediate equity cushion that absorbs early depreciation.
Tip 5 — Check Your Credit Score Before Applying
Credit score improvements, even modest ones, can produce meaningful APR reductions. A borrower at 699 who improves to 702 may move from the near-prime rate tier to the prime tier — potentially saving 2% to 3% APR on the loan. Request a free credit report from AnnualCreditReport.com, dispute any errors, and pay down credit card balances before applying. If your score is near a tier boundary, delaying the purchase by 3 to 6 months to improve credit can save thousands of dollars in financing costs.
Tip 6 — Avoid Add-Ons That Inflate the Loan Balance
Dealership finance offices routinely offer add-on products at loan closing — extended warranties, GAP insurance, paint protection, interior protection, and tire and wheel coverage. These products are often legitimately useful but are almost always priced 2x to 5x what the same coverage costs from third-party providers. Adding $3,000 in dealer add-ons to a 72-month loan at 8.5% APR generates an additional $824 in interest — making a $3,000 product cost $3,824 in total. Purchase any add-ons separately after the vehicle purchase if desired.

Common Auto Loan Mistakes to Avoid
Mistake 1 — Focusing on Monthly Payment Instead of Total Cost
Monthly payment optimization is the most common and costly auto financing mistake. A buyer who extends a loan from 60 to 84 months to reduce the monthly payment by $120 may pay $4,500 more in total interest over the loan term. The monthly payment is a cash flow metric; the total loan cost is the true economic measure of the financing decision. Always use an auto loan calculator to compare total cost across scenarios before committing to a term.
Mistake 2 — Rolling Negative Equity Into a New Loan
Rolling negative equity — the amount owed above the trade-in value on an existing vehicle — into a new auto loan immediately puts the buyer underwater on the new vehicle from the first payment. A buyer who owes $4,000 more than their trade-in is worth and rolls that deficit into a new $30,000 loan is effectively borrowing $34,000 for a $30,000 vehicle, generating interest on $4,000 that produces no asset value. Break the negative equity cycle by paying down the existing loan before trading in or by making a cash payment to cover the deficit.
Mistake 3 — Accepting the First Financing Offer
The first financing offer from a dealership is rarely the best available rate. Dealers submit applications to multiple lenders and present the offer that maximizes dealer profit — which typically means the highest rate the buyer will accept. Buyers who arrive with pre-approval from an outside lender have leverage to negotiate or simply use their own financing. The 30 minutes spent obtaining one pre-approval before shopping for a vehicle routinely saves $1,000 to $3,000 in total interest on a typical auto loan.
Mistake 4 — Ignoring Total Out-of-Pocket Costs
The vehicle price is only one component of the true purchase cost. Taxes, title fees, registration, documentation fees (dealer doc fees), and dealer preparation fees add $1,500 to $4,000 to the transaction in most states. Financing these costs rather than paying them upfront adds them to the loan principal and generates interest charges on every dollar. Buyers should calculate the full out-the-door cost — vehicle price plus all fees and taxes — before determining the appropriate down payment and loan amount.
Real-World Applications
New Car Financing — Using the Calculator Before the Showroom
The auto loan calculator is most powerful when used before entering a dealership. By calculating the maximum affordable loan amount based on a comfortable monthly payment target, buyers can establish a vehicle price ceiling before seeing inventory. A buyer who determines that a $550 monthly payment is their maximum can work backward — at 7% APR over 60 months, that payment corresponds to approximately $27,600 in financing. Adding a $6,000 down payment means the vehicle price ceiling is approximately $33,600 before taxes and fees.
Used Car Financing — Higher Rates, Shorter Terms
Used vehicle loans typically carry higher APRs than new vehicle loans — by 1% to 4% for equivalent credit profiles — because used vehicles depreciate faster, carry higher maintenance risk, and have shorter remaining useful life as collateral. Additionally, most lenders restrict used vehicle loan terms based on vehicle age — a 10-year-old vehicle may only qualify for a 48-month loan regardless of the buyer’s preference for a 72-month term. The auto loan calculator accommodates any term and APR combination to reflect the actual financing available on a specific used vehicle.
Refinancing — Using the Calculator to Evaluate Savings
Auto loan refinancing replaces an existing loan with a new loan at different terms — typically a lower APR made possible by credit score improvement, market rate reductions, or moving from a dealer-marked-up rate to a direct lender rate. The calculator quantifies refinancing savings by comparing total interest on the existing loan versus total interest on the proposed refinanced loan. A borrower who refinances a $22,000 balance from 9.5% APR to 6.5% APR over the remaining 42 months saves approximately $1,890 in total interest — a meaningful return on the administrative effort of refinancing.
CFA and Financial Planning — Auto Loan in Personal Finance Frameworks
In personal financial planning, auto loan debt management is evaluated as part of the consumer debt hierarchy — typically ranked after high-interest credit card debt and above mortgage debt in repayment prioritization. Financial planners use the 20/4/10 rule as a practical auto financing guideline: a 20% minimum down payment, a maximum 4-year (48-month) loan term, and total vehicle expenses (including insurance, maintenance, and fuel) not exceeding 10% of gross monthly income. The auto loan calculator supports this framework by generating instant scenario analysis against any combination of these parameters.
Final Thoughts
The auto loan calculator is the essential tool for converting a vehicle’s sticker price into its true financial cost. A car priced at $32,000 can cost anywhere from $27,500 to $40,000 depending on financing choices — the difference between 20% down with a 36-month loan and zero down with an 84-month loan. Use the calculator above to compute your monthly payment, compare total cost across loan terms, and identify the financing structure that minimizes the total amount you pay for the vehicle. Always optimize for total loan cost, not monthly payment.

Frequently Asked Questions
How do I calculate my auto loan monthly payment?
The monthly auto loan payment is calculated using the amortization formula: M = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1], where P is the loan principal, r is the monthly interest rate (APR ÷ 12), and n is the total number of payments. For a $25,000 loan at 7.5% APR over 60 months, the monthly payment equals $500.56. The free Auto Loan Calculator at intelcalculator.com/finance/auto-loan/ performs this calculation instantly — enter your loan amount, APR, and term to get your exact monthly payment.
What is a good interest rate for an auto loan?
A good auto loan interest rate is below 6.5% APR for new vehicles and below 8.0% APR for used vehicles for borrowers with good credit (700+ credit score) as of 2024–2025 market conditions. Borrowers with excellent credit scores above 750 can typically qualify for APRs between 4.5% and 6.0% on new vehicles. The best rates are available through credit unions, which consistently offer 0.5% to 2.0% lower rates than banks and dealerships for equivalent credit profiles.
How much should I put down on a car?
The recommended minimum down payment is 20% on a new vehicle and 10% on a used vehicle. A 20% down payment on a new car protects against immediate negative equity — since new vehicles depreciate 15% to 25% in the first year, a 20% down payment creates an equity cushion that absorbs early depreciation. Buyers who cannot afford a 20% down payment should consider a less expensive vehicle, delay the purchase to save more, or increase the down payment using trade-in proceeds to reach the 20% threshold.
Is it better to finance a car for 48 or 60 months?
A 48-month loan term is financially superior to a 60-month term for most buyers — it generates significantly less total interest, builds equity faster, and reduces the period of negative equity exposure. On a $25,000 loan at 7.5% APR, the 48-month term saves $1,822 in total interest compared to 60 months. The monthly payment difference is approximately $106 per month. If the $106 difference is manageable in the household budget, the 48-month term is the correct financial choice.
What credit score do I need for an auto loan?
There is no universal minimum credit score required for an auto loan — lenders exist at every credit tier, including deep subprime lenders who finance borrowers with scores below 500. However, the practical threshold for competitive financing rates is a credit score of 660 or above for prime-tier APRs. Borrowers with scores below 600 typically face APRs of 15% to 25%+, which dramatically increases the total cost of vehicle ownership. Borrowers with scores below 580 should seriously consider delaying the purchase to improve credit, as the rate premium can add $5,000 to $15,000 to the total cost of financing a vehicle.
Can I get an auto loan without a down payment?
Zero down payment auto loans are widely available but carry significant financial risk. Without a down payment, the buyer immediately enters negative equity — owing more than the vehicle is worth — because vehicle depreciation begins the moment the car leaves the lot. In the event of an accident or total loss, an insurance payout based on market value may be $3,000 to $8,000 less than the outstanding loan balance. GAP insurance (Guaranteed Asset Protection) covers this deficit but adds additional loan cost. If financing with zero down, GAP insurance is strongly recommended.
How does trade-in affect an auto loan?
Trade-in value functions as a down payment — it reduces the loan principal before interest is calculated. If a vehicle has a trade-in value of $8,000 and there is no remaining loan balance on it, the $8,000 directly reduces the new vehicle’s loan amount. If the trade-in has a $5,000 remaining loan balance, the net trade-in value is $3,000 ($8,000 value minus $5,000 owed). If the trade-in has negative equity — the loan balance exceeds the trade-in value — that deficit is added to the new loan principal, increasing both the loan amount and total interest paid.
What happens if I pay off my auto loan early?
Paying off an auto loan early eliminates all remaining interest charges — which can save hundreds to thousands of dollars depending on how early in the loan term the payoff occurs. Most auto loans do not carry prepayment penalties, so extra principal payments or a full early payoff reduce total interest cost with no fee. To maximize interest savings, make extra payments early in the loan term when the interest portion of each payment is highest. Even one extra payment per year on a 60-month loan reduces the total interest paid by 8% to 12% and shortens the loan by 4 to 6 months.
