How to calculate zakat
Calculating zakat is simpler than it looks: add your zakatable wealth, subtract outstanding liabilities, and apply the 2.5% rate to the result. This guide walks through each step, where your responsibility for nisab and the lunar year begins, and sticks to the same numbers used by Klar’s zakat calculator.
What goes into the zakat base?
The zakat base is the wealth that reaches the nisab and completes a lunar (Hijri) year. The calculator covers three main categories: cash and savings, gold held as savings at the current market price, and investments such as shares and sukuk. Add any other zakatable category in the appropriate field, and always enter current values rather than purchase prices.
Subtracting liabilities
Outstanding liabilities are subtracted from total wealth before zakat is computed, because zakat is paid on what exceeds what you owe. A due liability is a debt payable now, not a long-term loan spread over its full term. If liabilities exceed the total wealth, the base becomes zero and no zakat is due in this calculation.
Applying the rate
The standard rate on cash, gold and investments is 2.5% of the zakat base — one fortieth. The calculator works it out directly: zakat base × 2.5%. The nisab field is informational only and does not affect the result: enter the wealth above nisab there, but the computed amount depends on the base entered above.
A worked example
Using the same values as the calculator: cash and savings of 10,000 dinars, gold worth 5,000 dinars, investments of 2,000 dinars, and outstanding liabilities of 1,000 dinars. The base is 10,000 + 5,000 + 2,000 − 1,000 = 16,000 dinars, and the zakat due is 16,000 × 2.5% = 400 dinars.
Nisab and the lunar year are your call
The calculator does not check two conditions that rest on you: reaching the nisab (a threshold often estimated at the value of 85 grams of gold) and the passing of a full lunar year over the wealth. The contemporary nisab is set by the prevailing gold price on the day zakat is paid. Verify both conditions before treating the result as due; the calculator only gives the amount owed on the base you entered.
Practical notes
Gold is valued at the current market price, and zakat on trade assets and inventory has its own basis and rates outside this calculator. Common mistakes: computing zakat on total savings without subtracting liabilities, and forgetting to include gold or investments in the base. This is a general reference tool; where details differ, consult someone whose knowledge you trust.
Key takeaways
- Zakat base = cash + gold + investments − outstanding liabilities.
- The standard rate on wealth is 2.5% of the base.
- Liabilities are subtracted first, and can reduce the base to zero.
- Nisab and the lunar year are your responsibility, not tracked by the calculator.
- Gold is valued at the current market price.
Frequently asked questions
What is the nisab?
A minimum wealth threshold at which zakat becomes due, often estimated at the value of 85 grams of gold. The nisab field in the calculator is informational; you check the condition yourself.
Does the calculator track the passing of a lunar year?
No. It computes the amount on the base you entered only, and checking the lunar year and nisab remains your responsibility.
Are business assets included?
No. The calculator covers cash, gold and investments, and trade zakat has its own basis.
