Zakat Calculator (Sri Lanka, LKR)
Work out your Zakat on cash, gold, silver, business stock and receivables at the fixed 2.5% rate, after checking your wealth against the nisab — all in Sri Lankan rupees, entirely in your browser, with every assumption stated and cited.
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.
- 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.
- 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.
- 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.
- 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.
- 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.

The nisab weights and the 2.5% rate on this page were last cross-checked against AAOIFI SS 35 and the NZF reference on 2026-06-08. Gold and silver prices are user inputs, not part of this verification. This tool computes a figure from your stated assumptions; it is not a fatwa.
