Sir I have 100 gm Jewellery Gold for wearing purpose to my wife, How much amount I have to pay as Zakath?

Ramadan Mubarak

I found this online.

2. How is the amount of Zakah on gold and silver estimated?

In case gold is not fully pure, we may make use of the following equation to find out the total amount of fine gold after leaving out the weight of other substances:
weight of gold x the standard of fineness x the gram value x 2.5%
Note: the gram value here means the value at the time when the gold reaches the weight at which Zakah is payable.
