Know the real monthly payment before you're at the dealer. Enter the price, your down payment and trade-in, the rate, and the term — and see the payment, loan amount, and total interest.
Estimate only — principal & interest on the financed amount. Excludes registration, dealer fees, and gap/warranty add-ons, and assumes tax is financed. Confirm the real figures with your lender.
Three things move the monthly number most: the amount financed (price minus down and trade-in), the rate, and the term. A longer term lowers the payment but raises total interest — you pay for the smaller payment.
Stretching to 72 months makes the monthly payment look affordable but costs far more interest and keeps you "underwater" longer. Switch the term above to see the trade-off in total interest.
With the standard loan amortization formula: the financed amount, the monthly rate, and the number of payments determine a fixed monthly figure that pays the loan off over the term. This calculator shows the payment and the total interest.
A bigger down payment lowers the amount financed, so it cuts both the payment and total interest — and reduces the risk of owing more than the car is worth. Try raising the down payment above to see the effect.
