A car-buying calculator that estimates monthly payments and borrowing cost after trade-in credit, taxes, and dealer fees. Use the tool above to enter a few clear inputs and get a practical answer you can use right away.
This auto loan calculator helps buyers estimate what a vehicle will really cost once down payment, trade-in value, taxes, fees, and APR are all included. It is useful for comparing dealer offers, judging affordability, and deciding how term length changes both the monthly payment and the total borrowing cost.
Formula and method
The calculator estimates the financed amount by starting with vehicle price, subtracting down payment and trade-in value, then adding estimated sales tax and fees. It then applies a standard amortized monthly car-loan formula using APR and the selected term to estimate payment and total borrowing cost.
Example
If a vehicle costs 32,000, you put 4,500 down, receive 3,500 for a trade-in, pay 7.5% sales tax, add 1,200 in fees, borrow at 6.9% APR, and repay over 60 months, the calculator estimates both the monthly payment and the full cost of financing.
