How it works
Zakat is 2.5% of the net wealth you have held for a full lunar year, once it reaches the nisab: the value of 85 g of gold or 595 g of silver (the widely used figures), or 87.48 g and 612.36 g in the classical convention. You choose the convention and the metal, and enter today’s gold and silver prices in your own currency, so no live prices are assumed. Scholars treat personal jewellery, debts and business assets differently, so choose the settings that match your own guidance.
