Does this include dealer fees?

No. Documentation fees, registration, and title costs vary widely by state and dealer, so add those separately to your budget.

Should I finance my trade-in tax credit?

Most U.S. states let you subtract your trade-in value before calculating sales tax, which this calculator already does.

How the auto loan calculator works

This calculator adds your state sales tax to the vehicle price, subtracts your down payment and trade-in value, then finances the remainder over your chosen term and APR — the same method used by most U.S. dealerships and auto lenders.

Ways to lower your car payment

Increase your down payment to reduce the amount financed.
Shop your APR with a bank or credit union before visiting the dealership.
Choose a shorter term to reduce total interest, even if the monthly payment is higher.
