mosque Calculated to Shariah-compliant formulas

Every Islamic calculator on CalcaTools uses formulas from recognised Shariah authorities — the Hilal Committee's Hijri conversion tables, the MWL/ISNA/Umm al-Qura prayer-time methods, the four-school consensus for Zakat Nisab, and the Faraid distribution rules from classical fiqh. The exact authority is cited on every tool page.

menu_book Sunni & Shia rules side by side

For tools where the calculation differs between schools (Faraid inheritance, certain Zakat triggers, prayer-time conventions), we surface the choice as a selector and document the difference in the methodology block. Pick the school that matches your tradition — the answer adjusts.

savings Zakat with the live Nisab

Zakat tools fetch the current spot gold/silver price (or let you enter your local rate) so the Nisab threshold reflects today's value, not a stale figure from last year. The 2.5% rate is the standard hawl-based calculation; agricultural Zakat (1/10 or 1/20) is available on the dedicated Ushr calculator.

verified For guidance, not a fatwa

These calculators give you the number — they do not give a fatwa. For complex personal situations (inheritance with revoked rights, mixed-asset Zakat, late prayer makeup rules), please confirm with a qualified scholar in your tradition. We're here to help with the arithmetic, not to replace your local imam.
