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.

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.

Frequently asked questions

How is inheritance divided in Islam?
The estate is divided in two stages. First, the Quranic heirs with fixed shares (fara'id) — spouses, parents, and children — receive their prescribed fractions. The residue (asabah) then goes to the nearest male-line heirs, with sons receiving twice the share of daughters as the Quran specifies. The calculator works through these rules in the correct order, including cases where shares need proportional reduction.
