Calculate your monthly car loan payments, total interest paid, and total loan cost. Compare different loan terms, interest rates, down payments, and trade-in values to find the best financing option for your next vehicle.
Auto loans are typically simple interest loans, meaning interest is calculated daily on the remaining principal balance. Your monthly payment goes toward both interest charges and principal reduction. Early payments primarily cover interest, while later payments focus more on principal.
Step-by-Step Example:
Vehicle Price: $35,000 | Down Payment: $5,000 | Trade-In: $3,000
Loan Amount (P) = $35,000 - $5,000 - $3,000 = $27,000
Interest Rate: 6.5% → Monthly rate (r) = 0.065 ÷ 12 = 0.0054167
Term: 48 months (n = 48)
Monthly Payment = $27,000 × [0.0054167(1.0054167)^48] / [(1.0054167)^48 - 1] = $639.64
1. Improve Your Credit Score: A higher credit score qualifies you for lower interest rates. The difference between a 5% and 10% rate on a $30,000 loan over 60 months is over $4,000 in extra interest!
2. Make a Larger Down Payment: Every $1,000 extra down payment reduces your loan amount and total interest paid. A 20% down payment is ideal.
3. Choose a Shorter Loan Term: While monthly payments are higher, you'll pay significantly less interest. Compare a 48-month vs 72-month loan on $25,000 at 6%: 48 months ($587/month, $3,176 interest) vs 72 months ($414/month, $4,808 interest).
4. Consider Refinancing: If interest rates drop or your credit improves, refinancing can lower your monthly payment and total interest.
| Term | Monthly Payment | Total Interest | Total Cost |
|---|---|---|---|
| 24 months | $1,203 | $1,862 | $28,862 |
| 36 months | $819 | $2,798 | $29,798 |
| 48 months | $627 | $3,744 | $30,744 |
| 60 months | $512 | $4,703 | $31,703 |
| 72 months | $436 | $5,674 | $32,674 |
What credit score do I need for a good auto loan rate?
• 740+ (Excellent): 4-6% APR
• 700-739 (Good): 6-8% APR
• 660-699 (Fair): 8-12% APR
• Below 660: 12-20%+ APR
Should I get pre-approved before visiting a dealership?
Yes! Getting pre-approved from your bank or credit union gives you negotiating power. Dealers often mark up interest rates to earn profit. Compare our calculator results with dealer offers.
How much car can I afford?
Financial experts recommend spending no more than 10-15% of your monthly take-home pay on car payments, and total vehicle expenses (payment + insurance + maintenance) under 20% of your income.
What is the difference between APR and interest rate?
APR (Annual Percentage Rate) includes interest plus fees. The interest rate is purely the cost of borrowing. Use APR for true loan cost comparison.
Can I pay off my auto loan early?
Most auto loans have no prepayment penalties. Paying extra each month reduces principal faster and saves significant interest. Even $50 extra per month can shorten your loan by months and save hundreds in interest.
