Nothing to save yet.

Nothing is kept once this tab is gone. Closing or reloading it loses your answers. Save a file to keep them — you can load it back later.

Nothing is stored on our side, so this file is the only copy of your answers. It is ordinary text and contains the names you entered — keep it somewhere private, and note that if you lose it there is no way for us to recover it.

Spouse

Number of wives

They divide the wife's share equally between them.

Children

Sons

Daughters

Children of a son who died first

Son's sons

Grandsons through a son who predeceased.

Son's daughters

Parents

Father

Mother

Siblings

Full brothers

Full sisters

Maternal half-siblings

Same mother only. They share equally regardless of sex. Classical texts call them uterine siblings.

Grandparents

Paternal grandfather

He stands in for the father, if the father has died.

Maternal grandmother

Paternal grandmother

Whether the father excludes her is a point on which the Hanbalis differ from the other three schools.

Half-siblings by the father

Half-brothers by the father

Same father, different mother. Classical texts call them consanguine.

Half-sisters by the father

More distant relatives

Distant relatives

A daughter's or a son's daughter's children, a sister's children, a brother's daughters, a maternal half-brother's children, the mother's father, the mother's brothers and sisters, the father's sisters, the father's maternal half-brother, a daughter of the father's brother, and the children of any of these — which takes in every cousin except a son of the father's full or paternal half-brother. A son of a full brother or of a half-brother by the father, and the father's full or paternal half-brother or his son, are not in this group: they inherit before everyone here, and this calculator cannot yet record them.

Estate value (optional)

Enter what remains after funeral costs and debts. Leaving it blank still gives you the shares as fractions.

Bequests — the wasiyyah

Up to one third may be left to people and causes outside the fixed shares. Enter each as a percentage of the estate.

Distribution

Heir	Share	Percent
Wife One eighth, shared equally, the deceased having left a child or a son's child.	1/8	12.50%
Son Takes the residue, two shares to the male against one to the female.	7/16	43.75%
Daughters (2) Takes the residue alongside, one share to the female against two to the male.	7/16 7/32 each	43.75%

The fraction is what governs, and it is the share of what the heirs divide. Percentages are rounded to total exactly 100, so two heirs holding an identical fraction can differ by a hundredth.

Across the schools

This distribution is identical under all four Sunni schools of law.

Before you rely on this

This calculates the religious shares only. In the United States a surviving spouse can usually claim a statutory minimum against the will regardless of these figures, and retirement accounts and life insurance pass by beneficiary designation without ever entering the estate.
