Zakat calculator
Add up what you hold, subtract the debts you owe now, compare against the nisab. If the threshold is met, zakat due is 2.5% of the base.
1. Choose your nisab
The nisab is the level of wealth above which zakat becomes due. It is expressed in gold or in silver — both are followed, and the choice is yours.
2. What you hold
Only wealth you have held for a full lunar year counts. Leave blank anything that doesn't apply.
All available money, whichever account it sits in.
Jewellery, coins, bars — at today's resale value.
Same principle as for gold.
Shares, funds, units — at today's market value.
A loan to someone you genuinely expect to be repaid.
What you have to repay in the short term. Deducted from the base.
3. Your result
Enter at least one amount to see your calculation.
The exact figure takes a year of tracking
Zakat is owed on the minimum amount you held across the whole lunar year — not on today's balance. Wazn tracks that minimum month after month and tells you what you actually owe, on the date you owe it.

How this is worked out
The rate: 2.5%
Zakat on monetary wealth is 2.5% (one fortieth), applied to the zakatable base once debts have been deducted.
The nisab: 87.48 g of gold or 612.36 g of silver
These weights come from a single hadith (Abu Dawud 1573) and don't change — what varies is which of the two to apply, hence the choice above. The gram conversion isn't unique either: this site uses 87.48 g / 612.36 g (the same value used by Islamic Relief and the National Zakat Foundation), while other well-known calculators use 85 g / 595 g, from a different historical dinar/dirham weight (4.25 g per dinar, 2.975 g per dirham). Both figures genuinely circulate — see Sources below.
The hawl: one lunar year
Zakat is due on what you have held for 354 complete days, not on what you hold today. This calculator works on a snapshot: that is the approximation every online calculator makes, and it is better said out loud.
What this tool is not
It is not a religious ruling. Schools differ on several points — the reference metal, how everyday jewellery is treated, how long-term debt is treated. For your own case, refer to a qualified person.

Frequently asked questions
Gold or silver: which should I choose?
Both are followed. The silver nisab is considerably lower, so more people are liable — many adopt it for zakat on money and savings on the grounds that it benefits recipients more. The gold nisab is higher and followed by others. This tool does not decide for you.
Should I count jewellery I wear?
This is precisely a point of difference: some exclude everyday jewellery, others include it in full. Enter it or not according to the opinion you follow.
What about my debts?
Debts due in the short term are deducted from the base. For long-term credit such as a mortgage, the most common practice is to deduct only the coming year's instalments, not the outstanding capital.
Are the prices up to date?
Gold and silver prices are read automatically every day, and the date of the reading is shown at the top of the page. You can also enter your own nisab if your local authority publishes one.
