Islamic Inheritance Calculator
Divide an estate under Islamic law between the spouse, sons and daughters, parents, and full brothers and sisters, with debts and any bequest taken out first, and 'awl and radd applied where needed.
Everything the person owned when they died: property, cash, gold, business share.
Paid first, including any unpaid mahr owed to a wife.
Paid next, up to one third of what's left. A bequest can't go to an heir.
Same father and mother. They inherit only when there's no son and no father.
The father's father. With no father, he inherits in the father's place.
A brother through the father only, a brother's son, the father's brother, or his son. When there's no son, father or full brother, the nearest of them takes what the fixed shares leave.

- Follows the Hanafi school for spouses, children, parents and full siblings, and gives any remainder to the nearest male relative on the father's side if you say one is alive. It doesn't divide for a son's son, paternal grandfather, grandmothers, granddaughters or half-sisters, and the other schools differ in a few cases.
- An estate division is a religious and legal matter: have it confirmed by a qualified scholar or mufti, and follow your country's succession process.
The order of payment
Estate → funeral costs and debts → bequest (up to 1/3, not to heirs) → heirs
The main shares
Husband: 1/2, or 1/4 with children. Wife or wives: 1/4, or 1/8 with children. Mother: 1/6 with children or two or more siblings, otherwise 1/3. Father: 1/6 with children, plus the remainder if there are only daughters. One daughter alone: 1/2; two or more: 2/3. With a son, the children share the remainder, a son taking twice a daughter's share.
Worked example
A man leaves Rs 1,000,000 after debts, a wife, one son and one daughter. The wife takes 1/8, Rs 125,000. The remaining 7/8 goes to the children in the ratio 2 to 1: the son takes 7/12 (Rs 583,333) and the daughter 7/24 (Rs 291,667).
What this calculator covers
It follows the Hanafi school for spouses, children, parents and full siblings. If you say a paternal half-brother, brother's son, paternal uncle or uncle's son is alive, the nearest of them takes any remainder instead of it returning to the sharers (radd). A son's son or paternal grandfather changes the shares more widely, so the calculator stops and asks you to see a scholar rather than give their share to others. Grandmothers, granddaughters, half-sisters and cases where the schools differ also need a scholar. Always have an estate division confirmed by a qualified mufti.
Questions people ask
How is an estate divided in Islam?
First the funeral costs and debts are paid, then any bequest (up to one third, and not to an heir). The rest goes to the heirs: fixed Quranic shares for the spouse, parents and daughters, and the remainder to residuary heirs such as sons, with a son receiving twice a daughter's share.
What does a wife inherit?
One eighth if her husband left children, or one quarter if he didn't. Two to four wives share that same eighth or quarter equally.
What is 'awl?
When the fixed shares add up to more than the whole estate, every share is reduced in proportion. A husband (1/2) and two sisters (2/3) come to 7/6, so they receive 3/7 and 4/7.
What is radd?
When the fixed shares come to less than the whole and there's no residuary heir, the surplus is returned to the sharers in proportion. Under the Hanafi school the spouse doesn't take part in radd.
Do brothers inherit if there's a son or a father?
No. Full brothers and sisters inherit only when the deceased left no son and no father.
What if an uncle or nephew is alive?
When there's no son, father or full brother, the nearest male relative on the father's side (a paternal half-brother, then a brother's son, then a paternal uncle, then his son) takes what the fixed shares leave. So a wife, daughters and a paternal uncle: the wife takes 1/8, the daughters 2/3 and the uncle the rest, with no radd. Answer yes to that question and the calculator gives him the remainder. A son's son or a paternal grandfather inherits in a son's or father's place; the calculator doesn't divide for them and asks you to see a scholar.
