About This Calculator

This calculator estimates your monthly auto loan payment using vehicle price plus sales tax, minus your down payment and trade-in value, amortized over the loan term at a fixed APR.

All calculations happen locally in your browser — no data is sent to a server. Actual loan terms, taxes, and fees vary by lender and state.

Frequently Asked Questions

How is sales tax calculated on a car loan?

Sales tax is typically charged on the vehicle's purchase price and added to the amount you finance, unless you pay it upfront. This calculator applies your sales tax rate to the vehicle price before subtracting your down payment and trade-in.

What's a good APR for a car loan?

Rates vary based on credit score, loan term, and whether the car is new or used. Well-qualified buyers often see rates in the 5-8% range, while shorter terms and larger down payments generally secure lower rates.

Should I include my trade-in value?

Yes — your trade-in value reduces the amount you need to finance, just like a down payment, which lowers both your monthly payment and total interest paid.

Does a longer loan term save me money?

A longer term lowers your monthly payment but increases the total interest you pay over the life of the loan. Use the term buttons to compare how 36 vs. 72 months affects your total cost.
