Why use TechiBhai's calculators
Every calculator on this page runs entirely in your browser — nothing you enter is stored, transmitted, or logged anywhere. Each tool is built around the actual current rules and rates for its subject, cross-checked against official sources and, where relevant, verified against published worked examples before publishing.
What makes these different from a generic search result
- Current rates and rules, not stale figures — every calculator states its "last updated" date and the specific rate or rule version it uses.
- Formulas shown, not hidden — each tool includes the actual math behind its result, so you can verify it yourself.
- Honest about uncertainty — where a figure is genuinely an estimate (like NEET rank conversion or 8th Pay Commission fitment factor), the tool says so explicitly instead of presenting a guess as fact.
- No account, no email capture, no paywall — every calculator is free and immediately usable.
