Ask anyone the zakat rate and the answer comes instantly: 2.5 per cent. Ask what the 2.5 per cent applies to, and the confidence usually evaporates. The rate was never the hard part. The base is – and the base is built in four steps.

Step one: check the threshold. Zakat is only due once your wealth reaches the nisab, classically set at 85 grams of gold or 595 grams of silver, converted to dollars at current prices. The two metals give very different figures, and which to use is itself a scholarly question – many advise the silver standard as the more cautious, since it brings more people into the obligation. Below the nisab, no zakat is due.

Step two: check the clock. Zakat falls due after your wealth has been held across one lunar year – the hawl. In practice, most people fix a personal zakat date, often in Ramadan, and assess everything they hold on that same date each year. Consistency of the date matters more than the date itself.

The rate was never the hard part. The base is.

Step three: build the base. On your date, total the zakatable assets: cash in every account, gold and silver, money owed to you that you expect to recover, business trading stock, and investments according to the method you have adopted for them. Then subtract immediate liabilities – debts due now, bills owing – with scholars differing on how far ahead deductible debts may run. What remains, if it still clears the nisab, is your zakatable wealth.

Step four: apply the rate. Multiply by 2.5 per cent – the classical rate for a lunar year – and the number that emerges is not a donation you are considering. It is an obligation you are settling, the purification of everything above it.

Four steps, one date, every year. The arithmetic takes an evening. The order it brings to your financial life – a complete annual audit of everything you own – tends to outlast the evening considerably.

THE SHORT VERSION

  • Zakat is due once wealth clears the nisab – 85 grams of gold or 595 grams of silver – held across a lunar year.
  • Build the base on a fixed annual date: cash, metals, recoverable receivables, trading stock and investments, minus immediate debts.
  • Apply 2.5 per cent to what remains– and keep the same method and date consistently from year to year.
