Formula
Zakat = 2.5% × (Cash + Gold and silver + Investments + Business assets − Debts due), payable if the total is at or above the nisab.
About this calculator
Zakat is due on wealth held for one lunar year above the nisab, the value of 87.48 g of gold or 612.36 g of silver. Because gold and silver prices change daily, enter today's nisab in your own currency. Rulings on jewellery, pensions and property differ between schools of thought, so consult a qualified scholar for your situation.
Amounts are shown without a currency symbol, so the calculator works for any currency: enter all values in the same one.
