How to use these calculators
Every calculator here works the same way. Enter what you know about the loan and the results update as you type. There is no submit button and no results page to wait for.
Three inputs do most of the work: the amount you want to borrow, the interest rate, and the term. Say you're pricing a $25,000 car loan at 6.5% over 60 months. Enter those numbers and you get a payment of about $489 a month. Bump the rate to 7.5% and the payment climbs to roughly $501. Knowing that a full point of rate costs about $12 a month on this loan is useful before you walk into a dealership.
If you don't have a rate quote yet, ask your bank or credit union, or start from a recent national average and adjust. Your credit score moves the real number quite a bit, so treat any average as a midpoint rather than a promise.
Below each calculator you'll find an explanation of how that loan type works, the formula behind the numbers, and answers to common questions. Our guides go deeper on topics like refinancing and debt payoff, and the glossary defines terms such as APR and amortization.
The math runs entirely in your browser, so we never see the numbers you type. There's no account to create, and nobody will call or email you afterward.
