Work out your car loan monthly payment including down payment, trade-in and sales tax. See total cost and interest paid.
Know your real car payment before you visit the dealer
Dealerships often quote a monthly payment without showing how taxes, fees, and term length affect the total. This calculator gives you the full picture: the amount you'll actually finance, the interest you'll pay, and the true total cost of the vehicle.
Tips to lower your auto loan cost
Put more down, keep the term as short as you can comfortably afford, and shop your APR with a credit union or bank before financing through the dealer. Even a one-percent lower rate can save hundreds.

Frequently asked questions
How is my car payment calculated?
We start with the vehicle price, add sales tax, then subtract your down payment and trade-in value to find the amount financed. That amount is amortized over your loan term at the given APR to produce the monthly payment.
Does a bigger down payment lower my payment?
Yes. A larger down payment (or trade-in) reduces the amount you finance, which lowers both your monthly payment and the total interest you pay over the life of the loan.
Should I choose a longer loan term?
A longer term lowers your monthly payment but increases total interest, and you risk owing more than the car is worth. Shorter terms cost more per month but far less overall.
Is sales tax included?
Yes. Enter your local sales tax rate and the calculator applies it to the price (less trade-in, where applicable) and rolls it into the financed amount.
