Enter the figures you want to check

Use the amount after additions, deductions, base limits and the zakat-subject share; do not enter total assets or sales. SAR 0–1,000,000,000; up to two decimal places, without grouping separators.

Choose the business’s confirmed period basis; commencement, cessation and mergers may need separate treatment.

1–730 days. Used only when “Other period” is selected.

How are the results calculated?

For a full Hijri year: zakat = zakat base × 2.5%.

For another period: zakat = base × 2.5% × period days ÷ 354; round the monetary result only at the end.

Assumptions and limits

  • This estimator uses a confirmed final base for a business assessed from statutory accounts under the 1445H regulation. Establishing liability, constructing the base and reviewing limits and deductions come first.
  • The displayed period rate is rounded to four decimal places for explanation; the monetary calculation uses the full fraction. Rounding the rate first can produce a different amount.
  • The model excludes estimated assessments and special merger, cessation and liquidation cases. Article 15 treats short commencement and cessation periods differently; confirm the chargeable period before entering its days.
  • This is an arithmetic review estimate, not a zakat return or an automatic liability determination. Values are not sent to ZATCA or the WaliERP team.

Understand the idea behind the calculation

Using the tool and understanding your results

Enter your business’s reviewed final zakat base and select its financial period. The calculator shows the period rate and zakat amount, with Hijri-year, Gregorian-year and custom-day options.

What amount should I enter as the zakat base?

Enter the final subject base after additions, deductions, base limits and the subject share. Do not simply enter sales or total assets: the calculator starts with a prepared base rather than constructing it from financial statements.

How does a Hijri year differ from a Gregorian year?

For a full Hijri year, the calculator applies 2.5% to the base. For a period measured in days, it uses base × 2.5% × days ÷ 354, so 365-day and 366-day results differ.

Can I use this for personal savings or gold zakat?

This tool is for businesses assessed from statutory accounts using a final zakat base. It does not calculate gold nisab, personal savings zakat or the base for businesses under estimated assessment.
