About

Most salary questions in India come down to simple arithmetic that is annoying to do by hand: what a hike percentage means in rupees, what a CTC figure looks like per month, when a notice period ends, and how many working days fall in a period. These calculators handle exactly those cases, with Indian conventions like rupee grouping, LPA and CTC built in.

Every calculator runs in your browser using plain JavaScript. There is no server-side processing of your figures, no account, no login, and no external calculation service. If you go offline after the page loads, the calculators keep working.

We do not publish a fixed nationwide holiday calendar, because holidays differ by state, employer and year. We do not claim to compute exact take-home salary, because that depends on your salary structure and tax situation. And we do not present anything on this site as legal, tax or financial advice.

The tools are written for salaried employees, job seekers, freshers and students in India, and for HR or payroll staff who need a quick working-day or notice-period count. No account, sign-up or personal detail is required to use any of them.

Each calculator implements a formula that is printed on its own page, so you can reproduce any result by hand. Each formula is checked against manually worked examples before the calculator is published, and every page lists the assumptions the tool makes before it produces a number. Where a real-world outcome depends on something we cannot know — your contract, your salary breakup, your state’s holiday list — we ask you for that input instead of guessing.

Results are estimates for comparison and planning. We do not claim payslip-level accuracy, and we say so on the pages where it matters.
