Nisab and the zakat year: when the obligation starts

Two gates, not one

Most people learn the rate before they learn the conditions. They know the figure of 2.5 per cent long before they know that the figure is irrelevant until two separate tests are passed.

The first test is a threshold. Your qualifying wealth has to reach a minimum level, called the nisab. Below that level, no zakat is due on that wealth at all. The threshold exists so that the obligation falls on those with a surplus rather than on those living at or near subsistence.

The second test is time. That wealth has to remain in your possession, at or above the threshold, for one full lunar year, called the hawl. The time condition exists so that zakat falls on settled, retained wealth rather than on money that passes through your hands.

Both gates must be open. Wealth above the threshold that you received last month has not yet completed a year. Wealth you have held for five years but which sits below the threshold has completed the time but not the amount. Neither triggers an obligation on its own.

These are not informal customs invented by individual communities. They are defined conditions, codified in the published standards that Islamic financial institutions applySource^source, and they sit inside a broader framework of obligations and instruments rather than functioning as a discretionary donationSource^source.

What nisab actually measures

The nisab is expressed in a physical quantity of monetary metal, not in a currency amount. That design choice is deliberate. Currencies inflate, get redenominated and vary between countries. A weight of gold or silver is a stable unit of measure across centuries and borders.

The classical measures come from two metals:

• a gold standard, derived from a quantity of gold dinars;
• a silver standard, derived from a quantity of silver dirhams.

Those classical quantities are conventionally converted into modern gram weights, and the conversions cited by different institutions differ slightly because the historical coin weights are reconstructed rather than measured directly. The commonly cited approximations are in the region of eighty-five grams of gold and around six hundred grams of silver, but you should take the exact figure from the authority you follow rather than from a general article, because that conversion is a scholarly judgement and not an arithmetic fact.

To turn a weight into a number you can compare your savings against, you multiply the weight by the market price of that metal on your valuation date. This means the nisab in currency terms moves. It is not a fixed number you memorise once. It is a live figure you look up annually, and national religious and government authorities are the appropriate place to obtain itSource^source.

Why the gold and silver standards give different answers

Gold and silver have not tracked each other in value for a long time. In the classical period the two standards were roughly equivalent. Today they are not, and the silver standard usually produces a substantially lower threshold in currency terms than the gold standard.

The consequence is direct and practical:

• using the silver standard, more people cross the threshold, so more people owe zakat, and the recipients receive more;
• using the gold standard, fewer people cross the threshold, so fewer people owe zakat.

Reasoning exists on both sides. Those favouring silver argue that the lower threshold is more consistent with the redistributive purpose and more protective of the poor, since the recipient benefits from a wider base of payers. Those favouring gold argue that the silver-derived threshold has fallen so low relative to modern living costs that it captures people who are not meaningfully in surplus, which is the opposite of the intent.

Some scholars offer a middle route, applying the silver standard to holdings that are predominantly silver or cash and the gold standard to gold, or applying whichever standard is more favourable to recipients. This is a live scholarly discussion. The honest position for a general article is to explain the mechanism and the consequence, tell you the choice matters, and send you to a qualified scholar for the ruling.

Choosing the standard that produces the lower liability, purely because it produces the lower liability, is not a method. Whichever standard you adopt, adopt it for a reason you could state out loud, and apply it consistently rather than switching whenever prices move in your favour.

The hawl, and why it is a lunar year

The holding period is measured in lunar years, not solar years. A lunar year runs roughly eleven days shorter than a Gregorian year. Over a working life that difference compounds into an extra payment roughly every thirty-three years, which is not a rounding error.

Two practical consequences follow.

First, your zakat anniversary drifts backwards through the Gregorian calendar. If you set your date in a particular month one year, it falls slightly earlier the following year. Anchoring to a fixed Gregorian date, such as the first of January, gradually understates the obligation because you are using a longer year than the one the rule specifies.

Second, if you genuinely cannot track lunar dates, some scholars permit using a solar year with a proportionally adjusted rate to compensate for the longer period. That adjustment exists precisely because the calendar mismatch is real. It is a concession with a correction attached, not a free simplification.

What starts the clock, and what does not stop it

This is where most of the practical confusion lives, because people imagine the rule is far stricter than it is.

The clock starts on the day your qualifying wealth first reaches nisab. That date, converted to the lunar calendar, becomes your anniversary.

Under the position most widely applied, once the clock has started:

• wealth that goes above and below the threshold during the year does not reset the clock, provided you hold at least nisab on the anniversary itself;
• new money added during the year is folded into the same anniversary rather than starting its own separate twelve-month count;
• spending during the year is simply reflected in a lower balance on the valuation date, not treated as an interruption.

The clock does reset if your qualifying wealth falls to zero, or on the stricter reading falls below nisab at any point and stays there, so that there is no longer a continuous holding to run the year on. If that happens, the year begins again when you next cross the threshold.

The reason the lenient reading dominates in practice is workability. If every salary credit started its own twelve-month clock, a person paid monthly would be running twelve overlapping calculations at all times, with a different valuation date for each deposit. No one would comply, and the outcome would be worse for recipients than a single annual assessment.

A worked timeline

Suppose your wealth history over one lunar year looks like this. All figures are hypothetical, in a single currency, and the nisab equivalent on the relevant dates is assumed to be 10,000.

1. **Month one.** You have 4,000 saved. You are below the threshold. No clock is running and nothing is due.
2. **Month three.** A bonus and some accumulated saving take you to 12,000. You have crossed nisab. The clock starts on this date. You record the corresponding lunar date as your anniversary.
3. **Month five.** A car repair and a family obligation take you down to 7,000. You are now below the threshold mid-year. On the widely applied position, this does not reset your clock, because you still hold qualifying wealth and the assessment point is the anniversary.
4. **Month eight.** Savings rebuild to 15,000. You do not start a second clock for the new money.
5. **Month ten.** You buy gold worth 9,000. This is a change in the form of your wealth, not an interruption to the holding period.
6. **Month twelve, the anniversary.** You value everything you hold. Cash of 11,000 plus gold valued at 9,500 gives 20,500. That is above nisab, so both gates are open, and the calculation proceeds on 20,500 net of any deductible liabilities.

Now change one detail. Suppose that in month five you had emptied every account to zero and held nothing qualifying at all for six weeks. On the stricter view the continuity is broken, the clock resets, and a fresh twelve-month period begins from the date you next crossed the threshold. Under that variation, nothing would be due on this anniversary, and your anniversary date would move.

The difference between those two versions is not the amount of money. It is whether continuity was broken. That is why the anniversary date, once set, deserves to be written down somewhere durable.

Setting and keeping your anniversary

A workable routine has four parts, and none of them require special software.

1. **Fix the date once.** Identify, as best you can, when you first crossed the threshold. If the exact date is unknowable because it happened years ago, choose a defensible date, record why you chose it, and keep it. A consistently applied approximate date is far better than an annual argument with yourself.
2. **Convert it to the lunar calendar and keep both.** Record the Hijri date as the authoritative anniversary and note the corresponding Gregorian date each year as a reminder trigger. Many people set a recurring calendar alert two weeks before, which gives time to gather statements.
3. **Snapshot on the day.** On the anniversary, take a written snapshot of every qualifying holding and its value. Screenshots of balances, a note of gold weights and purity, and the market prices used. This snapshot is what makes next year's calculation quick and this year's defensible.
4. **Record the treatment decisions, not just the numbers.** Which nisab standard you used, whether you included jewellery, how you handled long-term shares. The numbers change every year. The decisions should not, unless you have a reason.

That last point is the one most people skip, and it is the one that saves the most time. A year later you will remember that you paid. You will not remember why you valued the portfolio the way you did.

Edge cases that come up repeatedly

• **You moved country.** The obligation follows the person and the wealth, not the address. Changing residence does not reset the hawl. It may change the currency you report in and the authority you consult, but not the clock.
• **Your wealth is spread across several pots.** The threshold test applies to your qualifying wealth in aggregate, not pot by pot. Three accounts each holding less than nisab still cross the threshold together.
• **Irregular or seasonal income.** Volatility during the year is normal and, on the dominant view, irrelevant. The anniversary balance is what is assessed. This is a relief for anyone whose income arrives in unpredictable lumps.
• **You realise you missed past years.** Missed obligations are generally treated as still owed rather than expiring. Calculating them retrospectively is uncomfortable but not unusual, and a scholar can advise on how to estimate where records are incomplete.
• **You are in net debt.** If deductible liabilities reduce your qualifying wealth below nisab, the threshold gate closes and nothing is due for that year. This is the threshold doing exactly what it was designed to do.
• **Wealth held for you by someone else.** Ownership, not custody, is what matters. Money held in another person's account on your behalf is still yours for this purpose, and the reverse is also true.

What this article does not settle

It does not give you a nisab figure. That number depends on the standard you follow and the metal price on your date, and any figure printed here would be wrong within days.

It does not resolve the gold-versus-silver question, tell you which juristic position to adopt, or determine whether your particular circumstances break the hawl. It does not cover zakat al-fitr, which is a separate obligation with a separate basis and timing. It is not a fatwa, and it is not personalised financial advice.

What it does give you is the shape of the question. When someone tells you that zakat is due, you now know to ask two things before anything else: has the wealth reached the threshold, and has it been held for a full lunar year. If the answer to either is no, the rate never enters the conversation. If the answer to both is yes, the valuation work begins, and that is a different article.
