Auto Loan Calculator

The Auto Loan Calculator estimates a monthly car payment from vehicle price, tax, fees, trade-in, rebate, down payment, rate and term. QuickCalculators shows the amount financed, total interest and a month-by-month amortization schedule so the split between principal and interest stays visible.

      Calculate an auto loan payment

      Calculate an auto loan payment.

      Calculating an auto loan payment means financing the net amount after tax, fees, trade-in, rebate and down payment, then amortizing that principal at a stated annual rate. The Auto Loan Calculator applies a fixed monthly payment formula and returns the payment, totals and schedule for the entered term.

      The financed principal is price plus sales tax plus fees, minus trade-in, rebate and down payment. A five-year loan of $20,000 at 6.5% produces a level payment near $391, with early months weighted toward interest and later months toward principal. The Auto Loan Calculator keeps every cent exact so totals match the schedule.

      Include sales tax, fees and trade-in

      Include sales tax, fees and trade-in.

      Including sales tax, fees and trade-in changes the financed amount before interest begins. The Auto Loan Calculator folds those line items into the principal so the payment reflects the deal structure rather than sticker price alone. Sales tax applies to price in this model.

      Fees add cash due at signing that may be rolled into the loan. Trade-in and rebate reduce the amount financed dollar for dollar. Changing any of those inputs updates the payment and the interest total immediately.

      Read the amortization schedule

      Read the amortization schedule.

      Reading the amortization schedule shows how each payment splits into principal and interest and how the remaining balance falls. The Auto Loan Calculator lists up to the full term so the path to payoff is concrete. Each row lists period, payment, principal, interest and ending balance.

      Interest is charged on the current balance, so early payments carry more interest. The final payment adjusts so the balance ends at exactly zero.

      Correct a common misconception: sticker price equals loan amount

      Correct a common misconception: sticker price equals loan amount.

      Sticker price is not the loan principal. Tax, fees, trade-in, rebate and down payment change the financed amount. The Auto Loan Calculator starts from that net figure, which is why two buyers at the same MSRP can see different payments.

      Frequently asked questions

      How is a car payment calculated?

      A car payment is calculated by amortizing the financed principal at a periodic interest rate over the loan term. The Auto Loan Calculator uses the standard fixed-payment formula and shows the schedule.

      How does a trade-in reduce the loan?

      A trade-in reduces the loan by lowering the amount financed before interest is applied. The Auto Loan Calculator subtracts trade-in value from price, tax and fees when building principal.

      How does term length change the payment?

      A longer term lowers the monthly payment and usually raises total interest. The Auto Loan Calculator shows both effects when the term field changes.
