About PayMatrixCalc

Why We Built This

PayMatrixCalc was built by a Central Government PSU employee who got frustrated with incorrect, outdated, or misleading salary calculators on the internet. After the 7th Pay Commission, most online tools continued showing wrong DA percentages, old HRA slabs, or had broken inputs that didn't work on mobile.

This site exists to fix that. Every calculator here is built with the correct formula, updated within 48 hours of any Cabinet revision, and works flawlessly on mobile — because most govt employees check their salary on their phone.

Our Principles

• Accuracy: Every formula is cross-verified against official DoPT/Finance Ministry circulars.
• Updated: DA, HRA, and NPS rates are updated immediately after each Cabinet decision.
• Private: All calculations happen in your browser. Zero data is transmitted or stored.
• Free: All tools are permanently free. No paywalls, no registrations.
• Mobile-first: Designed to work perfectly on Android and iOS browsers.
