Islamic Inheritance Calculator — Distribute an Estate by Quranic Faraid Shares
Our Islamic law of inheritance calculator helps you estimate how a Muslim estate is distributed among surviving heirs according to the Quranic system of Faraid (fixed shares). Derived from Surah An-Nisa (verses 4:11, 4:12, and 4:176), this inheritance calculator Islamic tool is built on authentic principles used across the Sunni Hanafi school and the Shia Ja'fari (Ithna Ashari) school. Enter the estate value, select the surviving heirs, and instantly see each heir's percentage share and monetary amount, with the Quranic basis for every share.
A Hanafi Inheritance Calculator — and a Shia Inheritance Calculator
Most Muslims in Pakistan, India, Bangladesh, and Turkey follow the Hanafi inheritance calculator rules, so this tool defaults to the Hanafi school. Switching to Shia Ja'fari mode adjusts the two well-known differences: the treatment of radd (surplus redistribution) — which, under Hanafi law, excludes the surviving spouse, while the Shia inheritance calculator includes the spouse — and the rules for a paternal grandfather inheriting alongside siblings. Where the schools agree on a share, the result is identical.
Property Distribution in Islam — What Is Deducted First
Before any heir receives a share, Islamic law requires four categories to be settled from the gross estate, in order: (1) funeral expenses (kafan and burial), (2) outstanding debts owed by the deceased, (3) unpaid mahr (dower) owed to the wife, and (4) wasiyyah — a bequest to non-heirs, capped at one-third of what remains after the first three. The remainder is the distributable estate on which Faraid shares are calculated. This property distribution in Islam calculator applies all four deductions automatically.
Heirs Covered: Fixed Shares, Residue, 'Awl, and Radd
This Islamic inheritance calculator online handles the principal and extended heirs: husband (1/2 or 1/4) and wife (1/4 or 1/8), mother (1/3 or 1/6), father (1/6 plus residue), paternal grandfather and grandmother (1/6), daughters (1/2 or 2/3), sons and daughters as residuary heirs at the 2:1 ratio of An-Nisa 4:11, granddaughters (including the supplementary 1/6), full brothers and sisters (the Kalalah case of An-Nisa 4:176), and uterine (maternal) siblings (1/6 or 1/3). It also applies hajb (blocking) to exclude heirs overridden by a closer relative, 'awl (proportional reduction when fixed shares exceed 100%), and radd (redistribution of surplus when shares fall below 100% and no residuary heir exists).
The 2:1 Ratio Between Sons and Daughters
The rule that a son inherits twice the share of a daughter reflects the broader Islamic framework of financial responsibilities: men carry the duty of mahr (dower), family maintenance (nafaqah), and dependants, while a woman's inheritance is entirely her own with no obligation to spend it on the household. The 2:1 distribution is therefore an integrated ethical system, not an isolated judgement about worth.
Frequently Asked Questions
What is Faraid? Faraid is the Islamic law of inheritance — the fixed, divinely ordained shares assigned to specific heirs in the Quran. This islamic law inheritance calculator applies those shares automatically.
Does this work as a Hanafi inheritance calculator? Yes — Hanafi is the default, covering the rules followed by most Muslims in Pakistan and South Asia, including hajb, 'awl, and radd (spouse excluded from radd).
Is it also a Shia inheritance calculator? Yes — toggle to Shia Ja'fari mode for the school's radd treatment (spouse included) and grandfather-with-siblings rules.
Are debts and the wasiyyah deducted? Yes. Enter funeral costs, debts, unpaid mahr, and a bequest percentage (capped at one-third); the tool calculates shares on the net distributable estate.
Does it handle siblings and grandparents? Yes — full brothers/sisters (An-Nisa 4:176), uterine siblings (4:12), paternal grandfather, and grandmothers are all supported, with blocking rules applied.
Use this tool to estimate shares for planning and discussion, and formalize any real distribution with a qualified scholar or legal professional — especially for rare edge cases such as a grandfather with siblings under muqasama, the umariyyatain scenario, or estates crossing jurisdictions.
