About this tool

The car loan calculator handles the three things that decide your auto payment: how much you're financing, the rate, and how long you stretch it. Enter the vehicle's price, subtract your down payment and any trade-in value, and the calculator figures the loan amount automatically. Auto-loan terms typically run 36–84 months — longer terms drop the monthly payment but cost much more in interest. Use this to compare offers between dealerships, or to figure out how much car you can afford on a target monthly budget.

Frequently asked

Usually no. A 72- or 84-month auto loan often leaves you owing more than the car is worth (negative equity) for years. A 48–60 month term is a healthier balance.
