Work out gold zakat and the value of your holdings
Gold zakat is 2.5% once you reach the nisab (85g of 24K).
Work out your gold value by weight and karat.
Zakat falls due on gold once it reaches the nisab threshold and a full lunar year passes over it. The threshold is 85 grams of pure 24 karat gold or its equivalent, and the rate is 2.5% of the value. The calculator takes weight and karat, converts them to today's value, and returns what is due. If you hold several karats, combine them by value rather than by weight.
There is a well known difference of scholarly opinion on zakat for gold a woman wears regularly. One view holds there is none, treating it as clothing in use. Another holds it is due as on any gold. The calculator works from the weight you enter, and the choice on this question belongs to your school and to the scholars you follow.
To see what your holdings are worth right now, enter the weight and the karat and the current market value comes back. Keep in mind this is the value of the metal. What you would actually receive on a sale is somewhat less because of the shop's margin, and can be more if a piece carries artistic or antique value.
