For learnersHow to Use the Zakat Calculator (Nisab, Gold, Cash and Debts)
Understand nisab and use the free calculator with confidence — without treating it as a fatwa. · Free · About 3 min read · Updated September 2026
Zakat is one of the five pillars, and calculating it correctly matters to every Muslim who owns wealth above the nisab threshold. Our free zakat calculator on the tools page handles the arithmetic — this guide explains the numbers you need and the assumptions the tool makes.
Important: this page is educational. Zakat depends on your situation, your school of thought and your local prices; a calculator supports your decision, it does not replace a qualified scholar.
Nisab in plain words
Nisab is the minimum amount of wealth above which zakat becomes due. The tool uses two standard thresholds: 87.48 grams of gold or 612.36 grams of silver, at a 2.5% rate. You choose one standard (many people use the silver threshold, because it is lower and makes zakat due on smaller savings).
The tool needs today’s price per gram (or per tola) of the metal you choose, in one currency. The site does not guess prices — you enter what gold and silver are trading at locally.
What to enter
- Cash and bank savings in your currency.
- Gold and silver you own, in grams (and the current per-gram price).
- Money owed to you (receivables) and money you owe (debts due) — the tool deducts eligible debts.
- Business assets if you trade — the tool subtracts them only when you enter them.
Gold, silver and the tola unit
If your jeweller quotes prices per tola, the tool converts for you: one tola is 11.664 grams, so 7.5 tola of gold is exactly 87.48 grams — the gold nisab. Enter your weights in either unit; the calculator shows both so you can check your numbers.
The honest limits of any calculator
The tool assumes a completed lunar year (hawl) over the wealth, and it treats jewellery, debts and conventions as matters you should confirm with a scholar of your school. It does not issue a ruling, calculate zakat for a business with complex accounts, or replace the yearly review a serious Muslim makes with a trusted scholar.
Where to get help
Use the calculator to prepare your numbers, then ask your scholar or a trusted local imam to confirm the result. If you study with us, your Essential Fiqh instructor can teach the principles of zakat in depth — and the tool is always free on the tools page.
Frequently Asked Questions
Quick answers about using the zakat calculator.
What is nisab and why does it matter?
Nisab is the minimum wealth threshold above which zakat is due. The calculator uses 87.48 g of gold or 612.36 g of silver at 2.5%. If your total wealth reaches the threshold you choose, zakat applies at 2.5% of the eligible amount.
Which nisab should I use — gold or silver?
Practice varies. Many scholars and charities use the silver threshold because it is lower, which makes zakat due sooner and helps more people. Follow the position of the scholar you trust; the tool lets you choose either.
How is tola converted to grams?
One tola equals 11.664 grams. The calculator does this for you — for example 7.5 tola of gold is 87.48 grams, exactly the gold nisab used by the tool.
Does the calculator know today’s gold price?
No — prices change daily and differ by country, so you enter the current local price per gram or tola in one currency. The tool is honest about this and never guesses.
Is the calculator a religious ruling?
No. It is an arithmetic study aid. Eligibility, hawl, debts and jewellery follow the rules of your school of thought, so confirm the result with a qualified scholar before paying.
