About us

Why this site exists

Loan offers are full of numbers — rates, APRs, terms, fees — and it’s hard to see what they mean for your budget. Loan Calculator gives you a quick, honest way to check a monthly payment, see the total interest, and compare scenarios before you commit.

How the calculators work

Every calculator on this site uses the standard fixed-rate amortization formula, and the methodology is written out on each page. The calculations are tested against published worked examples. Worked examples in our guides are computed from the same code as the calculators, so the numbers always match.

Everything runs in your browser. There’s nothing to sign up for, and your loan details are not sent to a server or saved.

How we write our guides

• We explain how loans work in plain English, with worked examples you can check yourself.
• Factual and regulatory points link to primary sources such as the Consumer Financial Protection Bureau and Federal Student Aid.
• We state the limitations of each calculator rather than overstating its precision.
• Each guide shows the date it was last updated, and we correct errors when we find them.

What we are not

We are not a lender, broker or financial adviser. We don’t offer loans, collect applications, or rank lenders, and the calculators don’t favor any lender. Our content is general information, not personalized advice. See our disclaimer.
