Zakat on crops and fruits, known as Zakat al-Zuru' wal-Thimar, follows rules that differ fundamentally from Zakat on cash, gold, or trade goods. Instead of a flat 2.5% rate compared against a currency-based Nisab, agricultural Zakat is paid in kind — a portion of the harvest itself — and its Nisab is measured in weight: 5 Awsuq, commonly estimated at approximately 653 kilograms of the harvested produce. The rate owed depends entirely on how the crop was watered, a distinction rooted in a well-known Prophetic hadith: crops watered naturally by rain or a river, without irrigation cost or effort, owe a full tenth (10%), while crops watered through paid effort — a water-lifting machine, purchased water, or a costly irrigation canal — owe half that, a twentieth (5%). Many scholars also recognize an intermediate 7.5% rate for crops irrigated by both methods across a single growing season. This method is documented in classical Fiqh texts on Zakat al-Zuru' and remains the standard mainstream teaching applied to grains and fruits that reach the Nisab weight after harvesting and drying.
Most people are familiar with the 2.5% rate used for Zakat on cash, savings, and gold, so it often comes as a surprise that Zakat on crops and fruits works on an entirely different system. Understanding why — and how to apply it correctly — starts with recognizing that agricultural Zakat has its own dedicated category in Fiqh, separate from wealth-based Zakat.
The first difference is the rate itself. Rather than a single flat percentage, the rate owed on a harvest depends on how much effort and cost went into watering it. Land watered by rainfall, a river's natural flow, or seasonal flooding — with no meaningful cost to the farmer — owes a full tenth of the harvest, 10%. Land that needed paid irrigation — a pump, purchased water, or a costly canal system — owes half of that, 5%, since the farmer already bore a real financial cost to produce the crop. Many scholars also apply an intermediate rate of 7.5% when a single harvest was watered by both methods across the growing season, splitting the difference fairly.
The second difference is the Nisab itself. Rather than comparing a monetary value against 85 grams of gold or 595 grams of silver, crop Zakat compares the physical weight of the harvest against 5 Awsuq — a classical unit of volume commonly estimated at roughly 653 kilograms once converted to a modern weight measure. Only once the harvest reaches this weight does Zakat become due at all; smaller harvests, even if valuable, are exempt under the mainstream view.
The third difference, and often the most surprising to people used to cash Zakat, is that agricultural Zakat is traditionally paid in kind — as an actual portion of the harvest — rather than as a cash figure. A farmer who harvests 1,000 kilograms of rain-fed wheat, for example, owes 100 kilograms of wheat directly, calculated at the 10% rate. In practice today, many scholars and Zakat authorities accept paying the cash-equivalent value of that produce instead, which is far more convenient for both the farmer and the Zakat recipient, and this calculator includes an optional price field to estimate exactly that.
One practical note worth remembering: this calculation applies per harvest, not per year. A farmer who harvests two separate crops in the same year — say, wheat in one season and dates in another — calculates the Nisab and Zakat separately for each harvest, rather than combining them into a single annual figure the way cash and gold Zakat are combined. Keeping a simple record of each harvest's weight, irrigation method, and calculated Zakat also makes it far easier to stay consistent from one growing season to the next.
Agricultural Zakat follows its own category of rules established directly from a Prophetic hadith about irrigation methods, separate from the wealth-based Zakat applied to cash, gold, and trade goods. The rate (10%, 5%, or 7.5%) depends on how much effort or cost went into watering the crop, not on how long it was held.
The Nisab for crops is 5 Awsuq, commonly estimated at about 653 kilograms of the harvested produce. It is measured in weight because Zakat on crops is traditionally paid in kind — a share of the actual harvest — rather than as a cash value compared against gold or silver.
The classical default is to pay in kind, handing over the calculated weight of produce itself. Many contemporary scholars and Zakat authorities also accept paying the equivalent cash value for convenience, which is why this calculator offers an optional price field to estimate that equivalent.
Rain-fed (or naturally flooded) land receives water without the farmer paying for it or expending significant effort — rainfall, a naturally flowing river, or seasonal flooding. Irrigated-with-cost land requires paid effort — pumps, purchased water, or machinery — to bring water to the crop, which is why it owes a lower rate.
This calculator reflects the mainstream teaching most commonly applied to grains and fruits that can be stored and measured by weight after drying, such as wheat, barley, dates, and raisins. For other crop types, mixed harvests, or unusual farming arrangements, please consult a qualified scholar or your local Zakat authority, as this note also reminds above.
