Many of us have gold at home, but no one fully understands the exact Zakat due on it—especially if they have more than one piece or gold of different karat purities. You may think the matter is complicated, but in reality it is very simple once you understand the basics.

The first thing you need to know is that Zakat on gold is a duty, not a choice. Islam made it obligatory to purify wealth and help the poor and needy. The Prophet (peace be upon him) warned strongly against the one who does not pay it, saying that it is forbidden treasure.

The key point here is the Nisab. The Nisab is the minimum amount of gold that, if you possess it for a full lunar year, makes you obligated to pay Zakat on it. The basic Nisab is 85 grams of pure gold (24 karat). However, the calculation differs depending on the karat type you have.

If you have 21-karat gold, for example, the Nisab for 21-karat gold is about 97 grams. Why? Because 21-karat gold contains 87.5% pure gold, not 100% like 24-karat. So you need a greater weight to reach the same amount of pure gold.

If you have 18-karat gold, then the Nisab for 21-karat does not apply to you. Instead of calculating based on 97 grams, you calculate based on approximately 113 grams, because 18-karat gold contains only 75% pure gold.

The calculation is very straightforward once you know the weight:

First: Check exactly how many grams of gold you have.

Second: Make sure you have kept it for a full lunar year (about 365 days).

Third: Multiply the weight by the purity ratio. If you have 100 grams of 21-karat gold, multiply by 0.875 to get 87.5 grams of pure gold.

Fourth: Multiply the result by the current market price per gram.

Fifth: Take 2.5% of the final result—this is the Zakat you pay.

Practical example: If you have 100 grams of 21-karat gold, and the price per gram is 400 riyals, the calculation is:
100 × 0.875 = 87.5 grams of pure gold
87.5 × 400 = 35,000 riyals
35,000 × 2.5% = 875 riyals

So you pay 875 riyals in Zakat.

Very important: you must distinguish between types of gold:

1. If your gold is for saving and investment, Zakat is definitely due on it.

2. If the gold is jewelry you wear daily (rings, bracelets, necklaces), there is a difference of opinion among jurists. Most of them say there is no Zakat, but the Hanafi school says there is Zakat even on used jewelry.

3. If you have gold in investment funds or ETFs, Zakat is also due on it.

The matter also differs depending on your intention. If you bought gold intending to sell and trade, Zakat is definitely due. If you bought it only for adornment, there is a difference of opinion, but it is safer to pay.

If your gold has not reached the Nisab yet (less than 85 grams of pure gold), then there is currently no Zakat due on it. But when you collect more and reach the Nisab, you start calculating from that point.

You can pay Zakat in cash or in gold, whichever is easier. If you pay in cash, you calculate based on the market price on the day you pay.

Advice: When calculating the Nisab for 21-karat gold or any other karat, make sure you calculate it based on pure gold, not the total weight. Many people make mistakes on this point.

Zakat is not just a financial obligation—it is an act of worship and a way to purify your soul and your wealth. When you pay it with the right intention, you will feel reassurance, help those in need, and strengthen social bonds in the community. So don’t delay calculating and paying it when its time comes.
