Zakat Nisab: Gold or Silver, and Why It Changes Everything

One rate, two thresholds

The rate almost nobody argues about: 2.5% of your zakatable wealth, once a lunar year. The threshold underneath it is where the disagreement lives. Zakat is only due if your net wealth reaches the nisab, and classical fiqh gives two ways to measure that nisab — the value of 85 grams of gold, or the value of 595 grams of silver.

Those two weights are not arbitrary and they were not meant to compete. In the Prophet's time the nisab was 20 dinars of gold or 200 dirhams of silver, and those were the same amount of money: the gold-to-silver price ratio was about 1 to 7, which is exactly the ratio the modern grammage preserves, since 595 divided by 85 is 7. A payer could use either measure and land on the same answer.

Silver fell, and the two thresholds split apart

Silver lost its monetary role over the following centuries while gold kept it. The price ratio widened from roughly 1 to 7 into the range of 1 to 80 or 1 to 90, where it has spent most of the last decade. The nisab formula did not change, so the two thresholds it produces drifted more than a factor of ten apart.

Put real prices on it and the gap is concrete. Suppose gold trades at $80 a gram and silver at $0.95 a gram — plug your own local figures in, because both move daily. The gold nisab is 85 times $80, or $6,800. The silver nisab is 595 times $0.95, or $565.

Which one you use decides whether you pay at all

Consider a straightforward case. You hold $4,200 in cash, $3,000 in investments and $1,500 of gold jewellery, and you owe $6,500 that is due now. Your net zakatable wealth is $2,200.

Against the silver nisab of $565 you are well over the line and you owe 2.5%, which is $55. Against the gold nisab of $6,800 you are under the line and you owe nothing. Same wealth, same year, same 2.5% — and the entire obligation turns on which metal you measured with.

The case each side makes

Most contemporary zakat institutions default to silver, and the reason is straightforward: the lower threshold brings more payers into the obligation and therefore more relief to the poor, and where two defensible readings exist, the one that favours the recipient is preferred. Scholars in this camp also note that the silver nisab is what the fuqaha of several madhhabs treated as the operative measure.

The gold camp argues from intent rather than caution. The nisab was set at a level that marked a genuine surplus — wealth beyond what an ordinary household needed — and silver no longer marks that level anywhere. A $565 threshold catches people who are, in any practical sense, poor, which inverts what the institution was for. On this reading gold is the honest translation of the original threshold into modern money.

Neither position is fringe, so the practical guidance is unglamorous: follow the ruling of the scholar or institution you take your religion from, and then stay consistent year to year rather than switching to whichever measure happens to exempt you.

Three details that move the number more than you expect

The year is lunar, not solar. Zakat falls due once a full hawl has passed on wealth that stayed above the nisab, and a lunar year is about 354 days against the Gregorian 365. Payers who anchor to a Gregorian date drift about eleven days a year against the Islamic calendar; those who deliberately keep a Gregorian schedule are commonly advised to pay 2.577% instead of 2.5%, which is 2.5% scaled by 365 over 354.

Only certain debts come off. The deduction is for what you actually owe now, not the full outstanding balance of a long-term loan — a mortgage does not erase your zakat, though the instalments due within the year are usually treated as deductible. Getting this wrong in either direction moves the net more than any argument about metals does.

The nisab is a price in your own currency. Gold and silver are quoted internationally, so the threshold has to be converted at the rate on the day you calculate, and it moves whenever either the metal or your currency moves. Working from last year's figure is the most common error of all.

Work out your own

The zakat calculator takes your assets and debts, applies both the 85 gram and 595 gram thresholds, and shows which standard you clear — so you can see the disagreement in your own numbers rather than in the abstract. For the per-gram price in your currency, the currency converter handles the conversion, and the Hijri date converter fixes the anniversary of your hawl on the Islamic calendar so next year's calculation falls on the right day.
