How to calculate Zakat on your wealth
Zakat is a mandatory charitable contribution for Muslims whose net zakatable wealth reaches or exceeds Nisab for one full lunar year. This calculator totals your cash, precious metals, investments, and receivables, subtracts short-term debts, compares the result to a gold or silver Nisab threshold, and applies the correct Zakat rate. All math runs in your browser. Nothing is sent to a server.

What is Nisab?
Nisab is the minimum net wealth that makes Zakat obligatory. The two classical benchmarks are based on the market value of fixed weights of pure gold or silver. As of 2026-09-13, this tool uses:
- Silver Nisab: 612.36 grams of pure silver (widely recommended because the lower threshold benefits more recipients)
- Gold Nisab: 87.48 grams of pure gold
Multiply the chosen gram weight by your current gold or silver price per gram to get the dollar Nisab threshold shown in the results panel.
Zakatable assets and deductions
Include cash on hand and in bank accounts, the current market value of gold and silver you own, stocks and mutual funds held for growth, business inventory held for trade, and reliable money owed to you. Personal items such as your primary home, daily-use vehicle, clothing, and work tools are generally exempt.
Deduct only immediate short-term debts and expenses due now or within the current year. Long-term mortgage principal is not deducted in full in most scholarly opinions.
Zakat formula
If net zakatable wealth is at or above Nisab, Zakat is:
The 2.5% rate follows the Islamic lunar (Hijri) year. The 2.577% rate adjusts for the longer solar Gregorian year so the annual obligation stays proportionate.
Worked example
- Assets: $5,000 cash + $2,000 gold + $1,500 investments + $500 receivables = $9,000
- Short-term debts: $1,000
- Net zakatable wealth: $9,000 - $1,000 = $8,000
- Silver Nisab at $1 per gram: 612.36 g x $1 = $612.36 (threshold met)
- Zakat at 2.5% (Hijri): $8,000 x 0.025 = $200.00
Nisab gram weights and Zakat rates in this article reflect commonly cited Islamic standards as of 2026-09-13. Update gold and silver per-gram prices to match current market values before you pay.
