Estimates only. Not financial advice.

How it works

We add sales tax (on price minus trade-in, as many states allow), subtract your down payment and trade-in to get the amount financed, then amortize it over your term to find the monthly payment.

Tip: a larger down payment lowers both your monthly payment and the total interest you pay.

FAQs

How is a car payment calculated?

From the financed amount (price + tax − down − trade-in) amortized over the loan term at your rate.

Does trade-in reduce sales tax?

In many states, yes - tax is charged on the price minus the trade-in. This tool assumes that.

What term should I choose?

Shorter terms cost less interest. Avoid stretching beyond 60-72 months, which raises total cost and risk of being underwater.

Should I make a down payment?

Yes - even 10-20% down lowers payments, interest and the chance of owing more than the car is worth.

Are taxes and fees exact?

Tax rules vary by state and dealer fees differ. Treat this as a close estimate.
