Car Finance Calculator
Calculate a vehicle loan in detail: amount financed, monthly payment, sales tax, trade-in equity, total interest, total paid and a full amortization schedule.
Formula / method
Amount financed = vehicle price + modeled tax + fees − rebate − down payment − trade-in equity. Monthly payment follows standard amortization.
How to use
Use realistic distance, efficiency, price, speed and financing assumptions rather than best-case values.
Understanding your car-finance results
This calculator is designed to show more than a monthly payment. The amount financed is the portion of the transaction that becomes debt after the modeled down payment, trade-in equity, rebates, taxes and fees. Total interest is the financing cost paid over the modeled loan term, while total loan payments combines principal and interest.
Why the loan term matters
A longer term can reduce the required monthly payment while increasing the time interest accrues. Compare 48-, 60-, 72- and 84-month offers by both payment and total interest.
Example
Before you decide
- Use the actual tax and fee figures from the dealer or local authority when possible.
- Check whether a rebate requires special financing.
- Compare APR and total borrowing cost, not only the advertised payment.
- Trade-in negative equity can increase the new amount financed.
