The case for silver
The silver threshold is the lower of the two — often by a wide margin — and that is precisely its strength. A lower bar means more Muslims qualify as payers, which means more zakat flows to those entitled to receive it. Where the gold standard would exempt someone, the silver standard often draws them in, and the poor are the beneficiaries of that caution.
For the payer, silver is therefore the more cautious position: if you are unsure whether you owe, the silver threshold resolves the doubt in favour of giving. Many scholars consider this the safer default for that reason.
It is also the practical default of the field. The National Zakat Foundation (the UK’s major zakat institution) and most US and UK relief charities calculate eligibility against the silver nisab. If you give through such an organisation, you are very likely already using silver — and using it yourself keeps you aligned with how your zakat is actually distributed.
The case for gold
The gold threshold stays closer to what the nisab originally meant. In the prophetic economy, the nisab marked a household that was comfortably surplus — secure for a year, with wealth to spare. Gold has held that purchasing power far better than silver, which collapsed in relative value once it became an industrial commodity. So the gold nisab today still roughly tracks “genuinely well-off,” while the silver nisab can classify people of modest means — even those who are themselves struggling — as zakat payers.
This is the reasoning behind the gold preference in Nurturing Mountains, the Hanafi handbook this site’s tools follow. Its argument is that the law’s purpose — a clean line between those who should give and those who may receive — is better served in the modern West by the gold threshold, because it does not sweep the barely-getting-by into the ranks of the wealthy.
Choosing gold is not a way to pay less. It is a considered view that the gold weight, not the silver one, best preserves the original economic meaning of being “above the nisab.”
Either is valid — so be consistent
Both standards rest on sound classical evidence, and reasonable scholars hold each. This site does not issue a verdict between them; it gives you both numbers, refreshed daily, and lets you choose. Two practical principles, though, are worth holding to.
Be consistent. Pick a standard and keep it year after year. What you should not do is switch to whichever threshold happens to exempt you in a given year — that is choosing the outcome rather than following the law, and it empties the obligation of meaning.
Ask your scholar. If your situation is close to the line, or you follow a particular school or teacher, ask them which standard they advise — and follow it with confidence. A considered choice made on guidance is worth far more than an anxious one made alone.
Whichever you choose, the zakat calculator lets you toggle between gold and silver and shows the result for each. For the deeper background, read what the nisab is and the full guide to zakah.
