What counts as zakatable wealth
Zakat is due on the wealth you have held for one full lunar year, above a minimum threshold called the nisab. Zakatable assets generally include cash and bank balances, gold and silver, money in shares and investments, business inventory held for sale, and money owed to you that you expect to be repaid.
From that total you subtract your immediate liabilities, such as debts and bills that are due now. What remains is your net zakatable wealth. If it sits above the nisab, zakat is payable at 2.5 percent of that net figure.
Understanding the nisab threshold
The nisab is the minimum amount of net wealth a Muslim must hold before zakat becomes due. It is traditionally set as the value of 87.48 grams of gold or 612.36 grams of silver. Because those metal prices change, the nisab in your currency changes too, which is why you enter its current value in the calculator.
Many scholars recommend using the silver nisab because it is lower, which means more wealth becomes eligible and more zakat reaches those in need. Others use the gold nisab. Enter whichever value you follow, and the calculator will tell you whether your net wealth is above it.
How to calculate zakat on cash
To calculate zakat on cash, add up every cash balance you hold: physical cash, current and savings accounts, and cash sitting in mobile wallets. If that total, combined with your other zakatable wealth, is above the nisab and has been held for a full lunar year, the zakat rate of 2.5 percent applies to the full net figure, not just the cash portion.
Zakat on money works the same way whether it is in one account or spread across several: what matters is the combined total on your zakat due date, after subtracting debts you owe right now. Enter each cash balance into the calculator and it totals them automatically.
Zakat on gold and retirement accounts
Zakat on gold is due on jewellery and bullion you own, valued at its current market price on your zakat date, at the same 2.5 percent rate as cash. Add its value alongside your other assets in the calculator to see the combined figure.
A 401(k) or other retirement account is treated based on access: funds you can freely withdraw are generally zakatable now, while amounts locked away with penalties are often excluded until you can access them, with any zakat due calculated once withdrawn. Views differ between scholars, so treat this as a starting point and confirm the specific ruling for your account type.
