How to Calculate Zakat on Money and Gold — Step by Step

Why Zakat Trips Up So Many People

Everyone knows the figure: a quarter of a tenth, or 2.5%. The difficulty isn't the rate — it's the question that comes before it: 2.5% of what, exactly?

Do I count my salary, or only what's left of it? Does my wife's gold jewellery go in? What about my car loan — do I deduct the whole thing? And what if my balance rose mid-year and then fell again?

These questions are why so many people postpone the calculation year after year. In truth, learning how to calculate zakat on money and gold isn't complicated — it just needs a clear order: three conditions, a list of what goes in, and a list of what comes out. Let's unpack it.

The Three Conditions Before Any Calculation

1. Full ownership

The wealth you pay zakat on must genuinely be at your disposal. A salary not yet paid, a deposit you can't withdraw, or a loan owed by someone insolvent with little hope of repayment — none of these enter this year's calculation.

2. Reaching the nisab

The nisab is the threshold at which zakat becomes obligatory. It is measured against one of two things:

85 grams of pure gold (24k)
595 grams of silver

Because silver is worth far less today, using the silver nisab means zakat becomes due on smaller amounts — the more cautious position, and the one more beneficial to recipients, which is why many contemporary scholars prefer it.

3. A full lunar year (hawl)

The wealth must remain above the nisab for one complete Hijri year — roughly 354 days. This matters more than people realise: anyone calculating by the Gregorian calendar adds eleven days annually and gradually drifts past the correct date.

A common mistake: what counts is the start and end of the year, not the fluctuations in between. If your wealth hit the nisab in Ramadan, dipped in Shawwal, then recovered, the year isn't broken so long as it never fell below the threshold.

What Goes Into the Zakat Pool?

Cash in hand and in current and savings accounts.
Gold and silver — bullion or jewellery (jewellery kept for personal use is a genuine point of scholarly disagreement).
Stocks bought with the intention of resale, valued at market price on your zakat date.
Trade goods — anything purchased to be sold, valued at current selling price, not what you paid.
Recoverable loans you've extended to others.

What Stays Out?

Your home, personal car, household furniture, and work equipment you don't sell (workshop machinery, clinic devices). These are assets of use, not assets of growth — no zakat is due on them regardless of value.

The Karat Question: Calculating Zakat on Gold

Zakat attaches to the pure gold content, not the gross weight of the piece. A 21k bracelet is only 87.5% gold; the rest is other metals.

The formula: pure weight = total weight × (karat ÷ 24)

Example: 100g of 21k gold → 100 × (21÷24) = 87.5g of pure gold.

This single step meaningfully changes the result, and it's applied automatically the moment you select a karat in the zakat calculator — no manual arithmetic needed.

Deducting Debts: The Rule People Misread

Yes, debts are deducted — but only the instalments falling due within the coming year, not the entire outstanding loan balance.

Someone with a 600,000 mortgage repaying 40,000 a year deducts 40,000, not 600,000. Deducting the full balance would effectively exempt wealthy people from zakat altogether, which sits badly with the purpose of the obligation.

The Calculation, Step by Step

Fix your zakat date on the Hijri calendar — and keep it consistent every year.
Total everything in the pool: cash + balances + stocks + trade goods + pure gold value + loans owed to you.
Subtract short-term debts only.
Compare the result to the nisab using the gold or silver price on that day.
If it meets the nisab, multiply the net by 2.5% (or divide by 40).

A Worked Example: Abu Khalid

An employee in Riyadh whose zakat date falls on 1 Ramadan.

Gold nisab: 85 × 310 = SAR 26,350. The net comfortably exceeds it.

Zakat = 134,900 × 2.5% = SAR 3,372.5.

Ten minutes on paper — or under a minute if you enter the figures directly.

Frequently Asked Questions

How much is zakat on money?

Zakat on money is 2.5% (a quarter of a tenth) of net wealth that has reached the nisab and completed a full lunar year. Every 10,000 in wealth carries 250 in zakat.

How much is the nisab in riyals or dirhams?

The nisab equals the value of 85 grams of pure gold or 595 grams of silver, so it shifts with the daily price. Multiply the price per gram on your zakat date by 85 to get the figure.

Is zakat due on jewellery that's worn?

This is a genuine point of disagreement. The majority of jurists exempt jewellery kept for personal use, while the Hanafis and a number of contemporary scholars consider it due. Paying is the more cautious choice; following the majority position is also well grounded.

What if I missed zakat for previous years?

Zakat is a debt that doesn't lapse with time. Estimate your wealth for each missed year as closely as you reasonably can, and pay what's owed — in instalments if that's what your circumstances allow.

Should I pay zakat on my salary the moment I receive it?

No. Your salary simply joins your overall balance, and zakat falls due on the total when the lunar year completes — not on each payment separately.
