Islamic Inheritance Calculator

What Is a Islamic Inheritance Calculator?

Islamic inheritance law (Fiqh al-Mawarith / علم الفرائض) is one of the most precisely defined areas of Islamic jurisprudence. It specifies exact fractional shares (Fard) for up to 24 heirs, rules of exclusion (Hajb), residuary heirs (Asabah), and special adjustments when shares exceed 100% (Awl) or leave a remainder (Radd). The Quran dedicates detailed verses (4:11–12, 4:176) to inheritance, making it obligatory upon Muslims to distribute the estate correctly.

Distributing an estate incorrectly — or ignoring it entirely — is a serious sin in Islam according to many scholars. This calculator implements the Hanafi school rules (default in Pakistan, India, Turkey, Central Asia) and guides you through heir selection, share calculation and the final monetary distribution based on the estate value.

How to Use the Islamic Inheritance Calculator - Step by Step

1. 1

   Enter the net estate value

   Enter the total distributable estate after deducting funeral expenses, debts and any valid bequests (wasiyyah — up to 1/3 of estate to non-heirs).

2. 2

   Select all living heirs

   Check each category of heir that is present. Enter counts for heirs who can be multiple (sons, daughters, wives, siblings). The calculator automatically applies exclusion (Hajb) rules.

3. 3

   Calculate

   The calculator applies fixed Fard shares, assigns Asabah (residue) to qualifying heirs, and handles Awl (scaling down when shares exceed estate) or Radd (redistributing surplus).

4. 4

   Review the distribution table and chart

   See each heir's exact fraction, percentage and monetary amount. The pie chart visualises the distribution for easy understanding.

Frequently Asked Questions - Islamic Inheritance Calculator

Does this follow a specific madhab?

The calculator implements the Hanafi school of Islamic law, which is followed by the majority of Muslims in Pakistan, India, Bangladesh, Turkey, Afghanistan and Central Asia. Key differences from other madhabs (mainly in grandfather inheritance alongside siblings) are noted.

What is Awl?

Awl (عَوْل) means 'increase'. It occurs when the sum of all fixed shares (Fard) exceeds the whole estate (e.g., totals to 8/6). In this case, all shares are scaled down proportionally so the total equals exactly 1. The denominator is increased to accommodate all shares.

What is Radd?

Radd (رَد) means 'return'. It occurs when the total of all fixed shares is less than the entire estate and there are no Asabah heirs. The surplus is returned to (redistributed among) the non-spouse fixed-share heirs proportionally.

What is Umariyya (Gharawayn)?

The Umariyya is a special ruling by Caliph Umar ibn al-Khattab (RA) for the case: spouse + mother + father with no children. Normally the mother would get 1/3, but Umar ruled she should get 1/3 of what remains after the spouse's share — to prevent the mother from inheriting more than the father.

Does this cover grandchildren?

The current version covers the most common inheritance scenarios: direct children, parents, grandparents, spouse, and siblings. Grandchildren (son's children) and more distant relatives are not included in this version. For complex cases, please consult a qualified Islamic scholar.
