About Ganak

Ganak provides free, accurate, and instant online calculators for finance, health, math, tax, and everyday planning. We believe essential calculation tools should be accessible to everyone, anywhere, at any time — without sign-ups, subscriptions, or hidden fees.

We also offer region-specific calculators tailored to India, United States, United Kingdom, and Australia — with local tax rules, regulatory standards, and currency formatting.

Every calculator on Ganak follows a rigorous development and verification process:

• Authoritative sources: Formulas and classification standards are sourced from official bodies — WHO and CDC for health metrics, RBI and SEBI for Indian finance, IRS for US tax, and ECB for currency exchange rates.
• Automated testing: Each calculator has snapshot and golden tests that run on every code change. Golden tests compare outputs against known correct values with tolerance-based matching to catch regressions.
• Config validation: All calculator configurations are validated at build time for uniqueness of IDs, slugs, and SEO titles. Invalid configs fail the build.
• Continuous updates: Tax rates, financial rules, and exchange rates are updated as regulations change. Currency data is refreshed daily via automated pipelines.

Our editorial team reviews calculator accuracy, content quality, and user experience before each release. If you find an error, please report it — we take accuracy seriously.

No account required. No personal data stored. Every calculation runs entirely in your browser — nothing leaves your device. We believe tools should be accessible to everyone without compromising privacy or requiring unnecessary information.

Your inputs are never sent to our servers. When you share a calculator result via URL, the values are encoded directly in the link — no database, no tracking, no server-side storage.

Ganak is built and maintained by a small team of developers and data enthusiasts based in India. We combine software engineering with domain expertise in finance, health metrics, and mathematics to deliver calculators that are both technically sound and easy to use.

Made with care in India, used by people worldwide.
