About this tool
Work out the zakat due on your cash, gold, silver, business and investments against the gold or silver nisab.
The Zakat Calculator works out what you owe using the mainstream rule — (zakatable assets − immediate liabilities) × 2.5%, payable only when the net clears the nisab of 87.48 g of gold or 612.36 g of silver at the rate you enter. You list cash, bank balances, business stock, receivables, shares, gold and silver by weight, then deduct debts and bills due now, and it shows the line-by-line breakdown, the threshold under both standards, and the amount payable in rupees. It is an informational estimate: schools of thought differ on jewellery, debts and pensions, so confirm the final figure with a scholar you trust.
Open Zakat Calculator on AltFTool — it loads instantly in your browser.
Fill in Cash & bank, Business assets and Investments, then Gold you own (grams) and Silver you own (grams) with today's rate per gram.
Deduct Immediate debts you owe, Bills due now and Short-term loans & card dues, then choose the Silver standard or Gold standard nisab.
Read the zakat due — 2.5% of net zakatable wealth — and press Copy summary for the line-by-line breakdown.
Switch between the 87.48 g gold and 612.36 g silver thresholds and see both values at your own rates — and a warning when you owe on silver but would fall below the gold bar.
Enter grams and today's rate per gram; the same rate then sets your nisab, so the threshold moves with the market instead of sitting on a stale number.
Every line you entered is grouped and totalled, marked zakatable or deducted, and the whole summary — including which nisab standard you used — copies out as plain text.
2.5% of your net zakatable wealth, and only if that net is at or above the nisab. Net wealth means your cash, bank balances, gold, silver, trading stock, recoverable receivables and investments, minus the debts and bills genuinely due now.
Nisab is fixed in metal, not currency: 87.48 grams of gold or 612.36 grams of silver. Multiply either by today's rate per gram to get the threshold in your currency — the silver figure is far lower, which is why most scholars recommend it, as it brings more payers in for the benefit of recipients.
Not the whole loan. Most scholars allow only the instalments falling due within the year to be deducted, not the full outstanding balance, so enter that year's portion rather than the entire mortgage. Rulings on long-term debt vary between schools — check yours.
One full lunar year, or hawl — roughly 354 days, about 11 days shorter than the solar year, which is why your zakat date drifts earlier each Gregorian year. Dips in between do not matter; what counts is that you were above the nisab at the start and at the end of that year.
