Nisab is the wealth threshold below which no zakat is due - Islam's recognition that zakat is taken from wealth, not from subsistence. Simple in concept, it hides the single most consequential choice in the whole calculation: the threshold comes in two classical sizes, and in modern dollars they have drifted an order of magnitude apart. Whether you measure by gold or silver can decide whether you owe zakat at all. Here is the full picture, written August 5, 2026.

The two standards and where they come from
The Prophet, peace be upon him, set nisab in the money of his time: 20 gold dinars or 200 silver dirhams, alongside thresholds for livestock and crops. Scholars standardised the monetary thresholds by weight - 85 grams of pure gold, 595 grams of pure silver - and those weights still govern; only the conversion to dollars moves. When gold and silver were both circulating money, the two thresholds were roughly equivalent in purchasing power. They no longer are: the metals' prices have diverged over centuries, so the same two definitions now produce radically different dollar figures. At our early-August 2026 check of NZF Australia's daily published values, the gold-based nisab stood at $15,737.75 and the silver-based at $1,570.80 - a tenfold gap between two readings of the same rule.
What the gap does
Take an Australian with $6,000 in savings and no other zakatable wealth on their zakat date. By the silver standard they are above nisab and owe $150. By the gold standard they are below it and owe nothing. Multiply across a community and the choice of basis determines whether a large band of lower-wealth Muslims are zakat payers or potential zakat recipients. That is why serious institutions publish both numbers daily rather than quietly picking one - and it is why the question deserves a real answer rather than a shrug.
The case for each basis
| Basis | Threshold (Aug 2026) | The argument |
|---|---|---|
| Silver (595g) | $1,570.80 | More cautious and more generous to recipients: it brings more payers into obligation, and classical practice favoured the standard that benefits the poor; commonly recommended where a payer holds mixed wealth (cash, shares, crypto) |
| Gold (85g) | $15,737.75 | Closer to the original purchasing-power intent of nisab as a threshold of genuine surplus; silver's price has arguably collapsed below what subsistence-plus means, making the silver threshold catch people who are not wealthy in any real sense |
Both positions are held by serious contemporary scholars, and institutional practice varies. NZF Australia publishes both bases daily with an explainer and does not force the choice - its calculator lets the payer decide with guidance. The common practical counsel runs: if you comfortably exceed both thresholds, the question is academic - pay. If you sit between them, the silver basis is the safer religious choice (you pay when you might owe) and the gold basis is a legitimate position (that nisab was never meant to tax modest savings) - and a person in genuine hardship between the thresholds has real grounds for the gold view. Choose deliberately, ideally with advice, and stay consistent year to year.
Mechanics that flow from nisab
- Nisab tests your total zakatable wealth - cash, gold, shares, crypto, business assets combined - not each asset separately
- Crossing nisab starts your hawl (lunar year); zakat falls due if you remain above it at the year's end, on the common approach - a mid-year dip that recovers is generally tolerated, though positions differ on wealth that fully collapses and rebuilds
- Use the nisab value on your zakat date, not the day you first crossed - the threshold floats daily with metal prices
- Your own physical gold and silver count toward the same test at market value by weight
- If you are below nisab, no zakat is due - and voluntary sadaqah remains open at any wealth level
The takeaway
Living near the threshold: the cases the numbers create
The tenfold gap between bases creates a band of real people - holding somewhere between roughly $1,600 and $15,700 of zakatable wealth - whose obligation depends entirely on the choice this article described, so the practical cases deserve direct treatment. The student with $4,000 saved: above silver nisab, below gold; on the silver basis she owes $100, on the gold basis nothing - and if paying would genuinely strain her, the gold view's logic (nisab as a threshold of real surplus) speaks to her situation; if she can pay comfortably, the silver view's generosity costs her little. The recent migrant sending remittances whose balance oscillates across the silver line through the year: the hawl question joins the basis question - wealth must generally remain above nisab across the lunar year for zakat to fall due, and a balance that repeatedly collapses below the threshold restarts the clock on the common approach; a consistent annual check on one date keeps this manageable. The family holding most wealth as gold jewellery: their basis choice interacts with their school's position on jewellery zakatability - a household following the view that worn jewellery is exempt may hold metal above the gold nisab yet owe nothing on it, while cash savings are tested separately. Each case resolves the same way: one deliberate choice of basis, one considered position on the contested items, applied consistently and revisited only for genuine reason - not because this year's answer is cheaper.
And a communal note the thresholds imply: nisab is also the line between those who give zakat and those who may receive it. A Muslim below nisab facing hardship is not merely excused from paying - they are within the categories zakat exists to serve, and Australia's institutional channel distributes to exactly such cases locally. The threshold is not a tax bracket; it is the faith's definition of who carries whom.

The deeper lesson of nisab's design is worth carrying away: the threshold is set in real assets, not currency, which is why it has survived every monetary regime since revelation - dinars, dirhams, gold standards, fiat and whatever comes next. A threshold fixed in any currency would have been inflated into meaninglessness within a generation; a threshold fixed in metal recalibrates itself daily against whatever money happens to be. That design choice, made fourteen centuries before floating exchange rates, is also why the modern payer needs a daily-updated source rather than a memorised figure - and why the annual moment of checking it connects an Australian bank balance to the same weights the first community measured. Small administrative act, long chain of continuity. Check the number, choose the basis, pay what is due.
Nisab is the rare fiqh question where a live market price feeds directly into a religious ruling, which is exactly why relying on a daily-updated institutional source beats a number remembered from last year - by our reading the difference between a stale and current threshold can flip a borderline case. Check the current values, pick your basis with intention, and let the zakat calculator do the aggregation. For the full obligation once you clear the threshold, return to the complete zakat guide.
