What is an Islamic Inheritance Calculator?
An Islamic Inheritance Calculator is a specialized tool designed to help Muslims distribute the estate of a deceased person according to the laws of Fara'id (Islamic Jurisprudence). Unlike secular inheritance laws, Sharia law provides specific, fixed portions for certain relatives, ensuring a divinely ordained balance of wealth within the family.
Who should use it? This tool is essential for executors of a will, family members of the deceased, and legal professionals specializing in Sharia-compliant estate planning. A common misconception is that inheritance is left entirely to the discretion of the deceased; however, in Islam, only up to one-third of the estate can be allocated via a will (Wasiyyah), while the remaining two-thirds must follow the Islamic Inheritance Calculator logic.
Islamic Inheritance Calculator Formula and Mathematical Explanation
The calculation follows a hierarchical structure. First, fixed shares (Zawil Furud) are allocated, followed by the distribution of the residue (Asabah) to remaining relatives.
Step-by-Step Derivation:
- Identify Heirs: Determine which primary heirs (Spouse, Parents, Children) are alive.
- Calculate Fixed Shares:
- Wife: 1/8 if children exist, 1/4 if no children.
- Husband: 1/4 if children exist, 1/2 if no children.
- Mother: 1/6 if children or multiple siblings exist, 1/3 otherwise.
- Father: 1/6 if children exist.
- Calculate Residue: The remaining amount after fixed shares is distributed to "Asabah" (usually the Father or Children).
- Children's Ratio: Sons receive twice the share of daughters (2:1 ratio).
Variables Table
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| E | Total Net Estate | Currency | > 0 |
| S | Number of Sons | Count | 0 – 20 |
| D | Number of Daughters | Count | 0 – 20 |
| M | Mother's Presence | Boolean | Yes/No |
Practical Examples (Real-World Use Cases)
Example 1: Small Family
A man passes away leaving a wife, one son, and one daughter. The net estate is $120,000. Using the Islamic Inheritance Calculator:
- Wife gets 1/8 = $15,000.
- Remaining $105,000 is split between children (2:1 ratio).
- Son gets $70,000; Daughter gets $35,000.
Example 2: Parents and Spouse
A woman passes away leaving a husband and both parents, but no children. Estate is $60,000.
- Husband gets 1/2 = $30,000.
- Mother gets 1/3 of the remainder (Umarayn case) or 1/3 of total depending on school. Standard: Mother 1/3, Father takes residue.
- Result: Husband $30,000, Mother $20,000, Father $10,000.

- The Will (Wasiyyah): Up to 1/3 of the estate can be given to non-heirs or charities before Fara'id distribution.
- Homicide: Under Sharia law, an heir who causes the death of the deceased is disqualified from inheriting.
- Religion: Generally, inheritance only occurs between Muslims in traditional Fara'id.
Frequently Asked Questions (FAQ)
Can I give more to my daughter than my son?
According to the Islamic Inheritance Calculator rules, the 2:1 ratio is fixed for the estate. However, you can give gifts (Hiba) during your lifetime to balance the amounts.
What happens if there are no children?
If there are no children, the spouse's share increases (e.g., Wife from 1/8 to 1/4), and parents or siblings may receive larger portions.
Does this calculator include siblings?
This version focuses on primary heirs. Siblings usually only inherit if there are no children and sometimes no father.
What is 'Aul'?
'Aul' is a mathematical adjustment used when the total fixed shares exceed 1.0, requiring a proportional reduction for all heirs.
Are funeral expenses included?
No, you must subtract funeral expenses and debts manually before entering the amount into the Islamic Inheritance Calculator.
What if the deceased had multiple wives?
The 1/8 (or 1/4) share is shared equally among all wives.
Is the mother's share always 1/6?
No, it can be 1/3 if there are no children and no more than one sibling.
Can a non-Muslim relative inherit?
Standard Sharia rules state that inheritance is only between Muslims, but they can receive up to 1/3 via a Will (Wasiyyah).
