Formula
How the calculation works
Zakat is a fixed 2.5%, one fortieth, of qualifying wealth, due once a lunar year (the hawl) has passed and the wealth stands at or above the nisab threshold. It is a religious obligation rather than an income tax: the rate does not rise with the amount, and it is charged on the wealth itself. The tool applies that one rate; the year of holding and the ownership are conditions you bring to it.
The nisab is the threshold below which nothing is due, and classically it is the value of 87.48 g of gold, or the silver equivalent of about 612 g, so it moves as the gold price moves. The tool derives it when you enter a gold price, or you can type a figure. Above the line you pay 2.5% of the whole zakatable wealth, not 2.5% of the part above it: 10,000 with a nisab of 5,000 gives 250, not 125.
The rate is flat, so the arithmetic is easy and the work sits in the wealth figure. Zakatable wealth usually means cash, bank balances, gold and silver, business stock and money owed to you, less debts due now; the home you live in and the car you drive are not included. The tool will not sort that for you, so the number you type matters far more than the multiplication.
Common mistakes
- Charging 2.5% only on the excess above the nisab. Once the wealth clears the threshold the rate applies to the whole zakatable amount: 10,000 with a nisab of 5,000 gives 250, not 125.
- Leaving the nisab at zero. With no nisab and no gold price every figure counts as eligible, so the tool would charge 2.5% on a small balance that is really below the threshold.
- Running the rate on gross assets while ignoring debts due now, or counting the home and the car, which are not zakatable. The wealth figure is the whole calculation, so a wrong one gives a confidently wrong 2.5%.
When to use it
- Use it once you have totalled your zakatable wealth for the year and settled on a nisab, to get the 2.5% due and to check whether you are above the threshold at all.
- It cannot decide what counts as zakatable, confirm the hawl has passed, or rule on a complex case. For a plain cash-and-gold total it is enough; for business assets, shares or mixed holdings, take the figures to a qualified scholar.
Worked example
On 10,000 of wealth with a nisab of 5,000, 2.5% gives 250. Below the nisab nothing is due.
Common questions
What is the nisab?
Classically the value of 87.48 g of gold. It moves as the gold price moves, so enter the price and this works it out.
Which gold price should I use?
The local price on the day you are calculating. It moves daily, so an old figure will be wrong.
