How the calculation works

1. Gold and silver

Eligible weight in grams is multiplied by the price per gram. One tola is configured as 11.6638 grams.

2. Other assets and debts

Cash and eligible assets are added. Only liabilities the user considers deductible under trusted scholarly guidance are subtracted.

3. Nisab test

The user may compare net eligible wealth against gold Nisab (87.48g) or silver Nisab (612.36g).

4. Estimate

If net wealth reaches the selected Nisab, the calculator estimates Zakat at 2.5% for a completed lunar year.

Formula: (gold + silver + other eligible assets − eligible debts) × 2.5%

Important qualification

Jewellery, long-term debt, investments and other circumstances may be treated differently across schools of thought. Users should seek qualified guidance for their own circumstances.
