How the auto loan calculator works
Calculate an auto loan payment and compare principal, interest, and repayment cost.
Monthly payment uses the standard fixed-rate amortization formula based on principal, monthly APR, and number of payments.
Read our calculation methodology and limitations.
Compare auto financing beyond the advertised APR
The best loan quote is the one with the lowest appropriate total cost—not automatically the lowest payment.
Use the contract rate
Enter the actual interest rate used to calculate payments. If a lender quotes APR with fees, keep separately entered fees from being counted twice.
Check the maturity balance
A balloon lowers scheduled payments but leaves principal due at the end. Include that final amount when comparing total repayment.
Model early payoff
Extra principal can shorten repayment, but confirm how the lender applies overpayments and whether the contract has a prepayment charge.
Example
Financing $30,000 at 6.5% for 60 months spreads the principal and interest across 60 equal payments.
What affects the result
- Borrowing less has the largest direct effect on payment.
- A lower APR reduces interest on every payment.
- A shorter term raises the payment but usually lowers total interest.
