About KakouCalc
KakouCalc is a free suite of 77 financial calculators — loans and mortgages, investing, retirement, credit cards, auto financing, and everyday money math — gathered in one fast, no-nonsense place. No sign-up, no paywall, and instant results.
What we stand for
- Accuracy first
- Standard formulas, and every calculator checked a second, independent way by an automated test suite. See our methodology.
- Your privacy
- Calculations run in your browser. What you type is never sent to a server, saved, or shared.
- Genuinely free
- No account, no trial, no locked features. Every calculator and guide is open to everyone.
- Plain explanations
- The most-used calculators include a guide — what the tool does, the formula, a worked example, key terms, and FAQs — so you understand the number, not just read it.
Editorial independence
KakouCalc is independent. The calculators and guides are for education and planning — they are not financial, investment, tax, or legal advice. For decisions that matter, verify the figures and consult a qualified professional. How we build and check everything is documented on the methodology page.
