Determine the Zakat due date, usually one lunar year after your wealth first reached the nisab
Add up all Zakatable assets you own on that date
Include cash, bank balances, gold, silver, business inventory, trade goods, investments, and receivables likely to be paid
Exclude personal items such as your home, car, clothes, and household goods
Subtract immediate debts and liabilities due at that time
Compare the remaining amount to the nisab threshold
If the remaining amount is equal to or above nisab, Zakat is due
Calculate 2.5% of the Zakatable amount
Pay that amount to eligible recipients of Zakat
Repeat the calculation every lunar year on the same Zakat date
