Inheritance Calculator
Work out an estimate of how an estate is divided under Islamic inheritance law (faraid). Enter the net estate value and the surviving heirs, and the calculator shows each heir's Quranic share and monetary amount. This is an educational guide — complex cases must be referred to a qualified scholar.
The estate
Enter the net value of the estate — what remains after funeral costs, outstanding debts, and any valid bequest (up to one third) have been settled. Faraid is applied to this net amount.
Surviving heirs
Select who has survived the deceased. This estimator covers the most common heirs: a spouse, children, parents, and full siblings.
The deceased can have a husband or a wife. For multiple wives, they share the wife's portion equally.
Estimated distribution
Select at least one surviving heir above to see an estimated distribution.
How Islamic inheritance works
Islamic inheritance law (faraid or mirath) distributes a person's estate among their heirs using fixed shares that are largely set out in the Quran, especially Surah An-Nisa (4:11–12). Before distribution, the estate first pays for funeral expenses, settles outstanding debts, and fulfils any valid bequest of up to one third of the estate.
Fixed shares and residue
Some heirs receive a defined fraction (for example a wife receives one eighth when there are children, or one quarter when there are none). After these fixed shares are given, the remainder passes to the residuary heirs (asaba). When sons inherit, each son receives twice the share of each daughter — a balance tied to the financial responsibilities men carry in Islam.
What this tool covers
This estimator handles the most common combinations of spouse, children, parents, and full siblings. It does not cover grandparents, grandchildren, half-siblings, or more distant relatives, and it flags intricate cases (such as ʿawl and radd) that need scholarly review.
Disclaimer: This calculator is a simplified educational estimate and is not a fatwa. The science of faraid is detailed and every family situation is unique. For an actual distribution, please consult a qualified scholar or a specialist in Islamic inheritance.
