About GotoCalc

GotoCalc is a free collection of calculators built to give fast, accurate, real-time results across finance, health, construction, math, conversions and everyday life. Every tool runs entirely in your browser — your inputs are never sent to a server.

Our goal

We want a calculator that is genuinely useful: clear inputs, transparent formulas, and a worked explanation alongside every result so you understand the number, not just see it.

Who runs it

GotoCalc is operated by Sivakumar Natarajamoorthy (operating GotoCalc). Have feedback or found an error? We'd love to hear from you on our contact page, or you can suggest a calculator you'd like us to build.
