💡 Why Use Our Vehicle Loan Calculators?

Americans owe more than $1.63 trillion in auto loans across 107 million active accounts. The average new car transaction price in the US is $48,528, and the average monthly new-car payment exceeds $730. Understanding the true cost of vehicle financing — including interest, taxes, depreciation, and insurance — is essential before signing any contract.

Our calculators use the standard amortizing loan payment formula (PMT) used by every US bank and credit union. You can model different down payments, trade-in values, sales tax rates, and loan terms to see exactly how each variable affects your monthly payment and total cost.

Start with the Auto Loan Calculator for car purchases, the Car Lease Calculator for leasing, or the Lease vs. Buy Calculator to compare both options side by side.
