How a Zakat Calculator Works
Direct answer
A basic Zakat calculator totals assets the user considers zakatable, subtracts eligible short-term liabilities, compares the net amount with the user’s chosen nisab, and applies 2.5% when the calculator’s conditions are met.
Key takeaways
- Use a current nisab value from a trusted authority you follow.
- Include only assets and liabilities relevant to your chosen method.
- The common calculator rate is 2.5% when conditions are met.
- A calculator is not a fatwa.
The calculator method
Enter eligible cash, precious metals, investments, receivables and business inventory according to the method you follow. Subtract eligible liabilities, then compare net assets with nisab.
Worked example
If net eligible assets are Rs 1,500,000 and that amount is above the nisab selected by the user, the 2.5% estimate is Rs 37,500.
Methodology vs religious ruling
Questions about hawl, jewellery, debts, mixed assets, business inventory or a particular school of thought may require qualified religious guidance. Seedha Hisab makes the mathematical method visible but does not issue a ruling.
