Question: How do I calculate the zakat due for gold of different carats? Do we have to find out how much per gram for 21 Carat, how much per gram for 22 Carat how much per gram from 24 Carat? Or can we give an average of 22 Carat?
Answer: Assalamu alaikum wa rahmatullah,
I pray this finds you in the best of health and faith.
For gold, zakat is due on the market value of the amount of gold one owns at time of the zakat due date.
Regarding your specific question, simply estimate the weight of actual gold for your jewellery (you can be “safe” in your estimate by assuming slightly more than your estimate, but not by too much lest it be excessive).
Don’t use “an average of 22 carat” but rather do each carat amount independently (21 carat, 22 carat, 24 carat, etc…).
And Allah knows best.
