About CreditCardTM

CreditCardTM provides free educational tools intended to help people better understand credit card calculations. The site is not a bank, lender, credit card issuer, credit repair company, or financial adviser.

Our calculators run entirely in your browser. Nothing you enter is stored on our servers or transmitted to third parties. The calculations use published, industry-standard formulas — the same math that underlies your statement — in a simplified form suitable for education.

We built this site because credit card math is often obscured behind marketing language and complicated statements. A clear number, produced by a formula you can inspect, is often the fastest path to understanding your options.

What we don’t do

• We do not recommend specific credit cards.
• We do not offer personalized financial advice.
• We do not sell, share, or store your calculator inputs.
• We do not require accounts, sign-ups, or subscriptions.
