How the gold Zakat calculator works
Gold is one of the clearest forms of zakatable wealth in Islam. When the gold you own reaches the nisab and you have held it for a lunar year, 2.5% of its value is due as Zakat. This tool removes the arithmetic: you enter the weight, choose the karat, and add the live 24-karat price per gram, and it works out the pure gold content, the market value and the Zakat owed — all privately in your browser.
Because most jewellery is not pure gold, purity matters. A 22-karat chain is 91.67% gold and an 18-karat ring is only 75% gold. The calculator converts your weight to a pure-gold equivalent using the karat factor, so two pieces of the same weight but different karat are valued correctly. It then checks that pure-gold figure against the 87.48-gram nisab.
If you weigh gold in tola — common across South Asia and the Gulf — switch the unit and the tool converts using 1 tola = 11.6638 grams. Whatever unit you use, the final step is the same: value above the nisab is multiplied by 0.025 to give the Zakat amount.
The formula explained
Pure gold content
Pure g = weight (g) × karat purity — 24k = 1.0, 22k = 0.9167, 21k = 0.875, 18k = 0.75.
Value & Zakat
Value = pure g × price per gram; Zakat = value × 0.025 when pure g ≥ 87.48.
Worked example
100 g of 22-karat gold, 24k price 60 per gram.
Common situations
Mixed jewellery
If you own pieces in different karats, calculate each separately and add the values, or convert all to pure-gold grams first. This keeps a 24k coin and an 18k bangle valued fairly.
Coins and bars
Investment coins and bars are usually 24k or 22k. They are clearly held as wealth, so Zakat applies straightforwardly once the nisab and lunar year are met.
Below the nisab
If your gold alone is below 87.48 g, combine its value with cash and silver in the main Zakat calculator — together they may still cross the threshold.
Price changes
Use the gold price on your Zakat anniversary, not the day you bought it. Because gold prices move, the value — and the Zakat — is taken at the moment Zakat falls due.

Frequently asked questions
How does karat affect Zakat on gold?
Karat measures purity. 24 karat is pure gold (100%), 22 karat is 91.67%, 21 karat is 87.5% and 18 karat is 75%. Zakat is based on the actual gold content, so the calculator multiplies your weight by the karat purity before applying the price and the 2.5% rate.
How do I convert tola to grams?
One tola equals 11.6638 grams. If you weigh gold in tola, multiply by 11.6638 to get grams. This calculator accepts grams or tola directly and converts for you.
Is Zakat due on gold jewellery?
According to the majority view, Zakat is due on gold jewellery that is owned as wealth once it reaches the nisab. Some scholars exempt jewellery in regular personal use. Many people pay to be safe; follow the ruling you trust.
What is the nisab for gold?
The gold nisab is 87.48 grams of pure gold. If your total pure-gold content reaches or exceeds this and a lunar year has passed, Zakat of 2.5% of the value is due.
