Calculating the gold nisab when the gold is of mixed karats

A question about calculating the gold nisab when the gold is of mixed karats, in which Jordan's General Iftaa Department answered that the nisab is 85 grams of 24-karat gold, 97 of 21-karat or 113 of 18-karat, and that with mixed karats the cash values are added at the buying price on the day zakat falls due. ¹

The questioner asked how to calculate the gold nisab when the gold is of several karats. ¹

The Department answered that zakat is due on money and on gold kept as savings or for trade when the total reaches the nisab and a lunar year has passed over it, and that the nisab is 85 grams of 24-karat gold, equal to 97 grams of 21-karat and 113 grams of 18-karat. ¹ It said that with several karats, the owner calculates the cash value of the gold he owns, adds the values together to determine the nisab, and pays zakat on the value in cash if the total reaches it, the relied-upon price being the buying price, meaning what a dealer pays the owner for the gold, on the day zakat falls due. ¹

Jordan's General Iftaa Department published this fatwa on aliftaa.jo as no. 4321, dated 4 March 2026. ¹ The museum records this text as a historical document attributed to the body or scholar that issued it; it issues no ruling of its own.
