About Calkura

Free, fast, and private financial calculators.

Calkura provides free online financial calculators — for compound interest, savings goals, loans and mortgages — that anyone can use without signing up. Every calculation runs entirely in your browser, so the numbers you enter are never sent to or stored on a server.

Our methodology

Our calculators use standard, well-established financial formulas (for example, the compound interest formula A = P(1 + r/n)nt plus a month-by-month simulation for recurring contributions). We cross-check results against closed-form formulas to ensure accuracy. Where a calculation depends on assumptions (such as compounding frequency or contribution timing), those assumptions are stated on the page.

Accuracy & disclaimer

Results are estimates for educational and informational purposes only. They are not financial advice, and actual returns, rates and outcomes vary and are not guaranteed. For decisions about your money, consult a qualified financial professional.
