Zakat Calculator
This calculator follows the formulas shown: 2.5% for savings and valued assets, 2.5% for business (net capital + stock + profit), and 10% (rain) or 5% (self-funded costs) for agriculture.
Note: This tool asks about haul (one Islamic year). Nisab varies by local authority and your chosen standard (gold or silver), so it is left as an optional check.
1) Choose zakat type
2) Basic checks
If you choose "No" for haul or nisab, the calculator will still show the maths, but it will also show a reminder.
3) Enter amounts (Savings and valued assets)
Formula: zakat = 2.5% × total savings
3) Enter amounts (Business)
Formula: zakat = 2.5% × (net capital + stock + profit)
3) Enter amounts (Agriculture)
