Zakat on your harvest — this Ushar in Islam calculator works out Ushr on crops. 10% on rain-fed crops, 5% on irrigated crops, 7.5% mixed. Due on the day of harvest, not after a year.
How it works
Three steps, under a minute:
Enter your harvest in kilograms or maund.
Pick how the land was watered — that sets the rate: 10%, 5% or 7.5%.
Choose the nisab view — Jumhur or Hanafi — and get your Ushar in kg, maund and cash value.
1 · Your harvest
Enter the total harvested weight, before any costs are taken off. Ushar is calculated on the gross harvest — see the note below about costs.
Total weight harvested, in the unit above. Nisab is 5 Wasq — about 653 kg, about 17.5 maund.
Price of the crop per kg on harvest day, to show the cash value of your Ushar. Leave blank if you only want the weight.
2 · How was it watered?
This sets your rate.
3 · Nisab view
The schools differ here, so we show both — pick the view you follow.
Jumhur (Shafi'i, Maliki, Hanbali): Ushar is due only if the harvest reaches 5 Wasq, about 653 kg. Below that, no Ushar is due under this view.
4 · Your Ushar due
Enter your harvest above to see your calculation.

Ushar — quick answers
What is Ushar in Islam?
Ushar (Ushr, literally “one-tenth”) is the zakat on agricultural produce. It is paid from the harvest itself, or its cash value, on the day of harvest.
Why 10% on some land and 5% on other land?
The rate follows the cost of watering. Land watered by rain, rivers or springs costs the farmer nothing to water, so the full tenth (10%) is due. Land irrigated with a tube well, pump or canal costs money and effort, so the rate is halved to 5%. Where a crop was partly rain-fed and partly irrigated, the commonly cited rate is 7.5%.
What is the nisab — and why do Hanafi and Jumhur differ?
The nisab commonly cited is 5 Wasq, about 653 kg of grain (about 17.5 maund). The Jumhur position (Shafi'i, Maliki, Hanbali) requires the harvest to reach that amount before Ushar is due. The Hanafi position commonly cited is that Ushar is due on any quantity of produce, with no minimum. This calculator lets you pick the view you follow and shows the other view alongside, so nothing is hidden.
When is Ushar due?
On the day of harvest, each time a crop is harvested. Unlike zakat on wealth, there is no one-year waiting period (hawl) for Ushar.
Can I pay in cash instead of crops?
Yes. Enter the market price per kg and the calculator shows the cash value of the Ushar due. Paying the crop itself is also valid.
What about cultivation costs — seeds, fertiliser, labour?
This calculator uses the gross harvest, which is the standard position. Some scholars allow deducting direct cultivation costs first. If you follow that view, subtract those costs from your harvest (in weight or value) first, then enter the net amount here — and confirm the approach with your scholar.
