Asset breakdown

Enter your assets above to see the line-by-line breakdown and your Zakat.

Scope: cash, gold, silver, trade inventory, good receivables and tradable investments, less currently-due debts. Excludes agricultural zakat (ushr), livestock, rikaz and Zakat al-Fitr — ask a scholar for those.

Nisab weights: gold 87.48 g, silver 612.36 g. Rate fixed at 2.5% (1/40) by ijmā‘. Sources: AAOIFI Shari'ah Standard No. 35 and the National Zakat Foundation — cited in full below. Verified against the 1/40 rule.

How it works

Zakat is an annual payment of 2.5% — a quarter of one tenth, or one fortieth (1/40) — on qualifying wealth that has been held for one full lunar year (the hawl), provided that wealth is at or above a minimum threshold called the nisab. This calculator follows the method set out in AAOIFI Shari'ah Standard No. 35 (Zakah) and the classical nisab weights documented by the National Zakat Foundation.

  1. Sum your zakatable assets. Add cash, the market value of gold (grams × price/g) and silver, business stock at its sale value, good receivables (money you expect back), and investments held for trade. Metals are valued at the current market price per gram, which you enter — the tool does not fetch a live price.
  2. Deduct liabilities due now.Subtract short-term debts that are currently payable (for example, this month's supplier bill or instalment). Long-term debt is deductible only to the extent of the amount due now. The result is your net zakatable wealth.
  3. Compute the nisab. Gold nisab = 87.48 g × gold price; silver nisab = 612.36 g × silver price. These are 20 mithqāl of gold and 200 dirhams of silver (often rounded to 85 g and 595 g). The basis you pick sets the threshold; silver is the default because its lower value means more payers qualify.
  4. Test the threshold. If your net wealth is at or above the nisab value, Zakat is obligatory (assuming the hawl is met). Otherwise no Zakat is due this year, and the tool shows how far you are from the threshold.
  5. Apply the rate. Zakat = net wealth × 0.025. The 2.5% rate is fixed by scholarly consensus (ijmā‘) and is never editable. The whole net amount is charged once you are above the nisab — not only the part above it.

One point of difference between schools is everyday gold jewellery worn for personal use. The Hanafi school counts it as zakatable; the Shafi‘i, Maliki and Hanbali schools exempt personal-use jewellery. The calculator defaults to including it (the more cautious choice for the payer) and lets you switch to the exemption. Because the figure depends on your stated school and the price you enter, this tool reports a number from your own assumptions — it does not issue a religious ruling.

Worked examples

Ramadan trader — above nisab

Silver basis · gold Rs 32,000/g · silver Rs 380/g · jewellery included

  1. Assets: cash 800,000 + stock 300,000 + gold 50 g × 32,000 (= 1,600,000) = Rs 2,700,000
  2. Liabilities due now: Rs 200,000 → Net = Rs 2,500,000
  3. Nisab (silver): 612.36 g × 380 = Rs 232,696.80
  4. Net 2,500,000 ≥ nisab 232,696.80 → Zakat is due
  5. Zakat: 2,500,000 × 2.5% = Rs 62,500

Salaried saver — below nisab

Silver basis · silver Rs 380/g

  1. Assets: cash Rs 150,000, nothing else → Net = Rs 150,000
  2. Nisab (silver): 612.36 g × 380 = Rs 232,696.80
  3. Net 150,000 < nisab 232,696.80 → no Zakat this year
  4. Shortfall to nisab: 232,696.80 − 150,000 = Rs 82,696.80

Gold-heavy holding — the jewellery toggle matters

Silver basis · gold Rs 32,000/g

  1. Jewellery included: gold 100 g × 32,000 (= 3,200,000) + cash 100,000 = Net Rs 3,300,000
  2. Net ≥ nisab → Zakat: 3,300,000 × 2.5% = Rs 82,500
  3. Jewellery exempt (majority schools): only cash counts → Net Rs 100,000
  4. Net 100,000 < nisab 232,696.80 → no Zakat. The difference is the cited school choice, not a bug.
