Zakat is due once your total qualifying wealth reaches the nisab threshold and has been held for a full lunar year. The rate on cash, gold, silver, and business assets is 2.5%. See the Zakat section on Practice for the full explanation, including agricultural and livestock zakat, which use different rates not covered by this calculator.
Nisab reference
Most scholars recommend the silver nisab, since its lower threshold means zakat reaches more of the poor. Gold nisab is a valid alternative, commonly followed for gold-heavy wealth.

Your assets
Cash on hand, checking/savings accounts, money owed to you that you expect to be repaid
Current market value of gold held as savings or investment — jewellery is a debated case (see Practice for the madhhab differences); include it if you follow the cautious view
Market value of stock-in-trade and business cash — not fixed assets like tools or property used in the business
Amounts due soon (this year) that you subtract before calculating — not a long-term mortgage
This is a study aid, not a fatwa. Zakat has genuine points of scholarly difference — what counts as zakatable, how to value a business, and jewellery in particular — that this simple calculator can't resolve for your specific situation. Confirm anything significant with a knowledgeable local scholar.
