Zakat is 2.5% of the wealth you have held for one lunar year, once that wealth is above a minimum called the nisab. This calculator works in any currency: enter your assets, what you owe now, and today's price of gold or silver.
How it works
Add up zakatable assets: cash and bank balances, gold and silver, investments, business stock, and money owed to you that you expect to be repaid. Personal items such as your home, car and clothing are not included.
Subtract debts and bills that are due now. The result is your net zakatable wealth.
The nisab is the value of 85 grams of gold or 595 grams of silver at today's price. If your net wealth is at or above it, and you have held it for a lunar year, zakat is 2.5% of the net amount. Many scholars recommend the silver nisab because it is lower, so more people pay and more reaches those in need.
A worked example
Assets of 5,000 cash, 2,000 in gold and 3,000 in investments total 10,000. After 1,000 of debts due, net wealth is 9,000. With silver at 1.20 per gram, the nisab is 595 × 1.20 = 714, so zakat is due: 9,000 × 2.5% = 225.
Questions people ask
Should I use the gold or the silver nisab?
Both are accepted. The silver nisab is much lower, so it includes more people and many scholars and zakat organizations recommend it. The gold nisab is also widely used. Follow the guidance you trust and apply it consistently.
Is zakat due on my pension or retirement account?
Scholars differ, especially when the money cannot be withdrawn yet. Some calculate zakat on the amount you could access today after penalties and taxes. Ask a scholar you trust about your specific account.
Does this replace advice from a scholar?
No. It handles the arithmetic for common cases. Complex situations, such as business partnerships, jewellery worn every day, or long-term debts, have different scholarly views and deserve personal guidance.
