Islamic Inheritance Calculator

Work out each heir's share of an estate under Sunni faraid rules. Enter who has survived the deceased and the calculator applies the Qur'anic fixed shares, residuary distribution, and the rules of awl and radd.

Please read first. This tool calculates shares under the mainstream Sunni rules of inheritance and covers the heirs most UK families need. It does not account for debts, funeral costs, or a valid bequest (wasiyyah, up to one third) — deduct those from the estate before entering the value below. For complex estates, disputed cases, or anything you are unsure about, please confirm the distribution with a qualified scholar or Islamic inheritance specialist before acting on it.

Set the number of each surviving relative. The estate value is optional — leave it blank to see shares as fractions only.

    How are the shares decided?

    Islamic inheritance follows fixed shares set out in the Qur'an (Surah an-Nisa). Certain heirs — such as a spouse, parents and daughters — receive a defined fraction (the furud). Whatever remains then passes to the residuary heirs (the asaba), starting with sons.

    A son takes the share of two daughters. A spouse's share halves when the deceased left children. A mother's share drops from a third to a sixth when there are children or two or more siblings.

    When the fixed shares add up to more than the whole estate, every share is reduced in proportion — this is awl. When they add up to less and there is no residuary heir, the surplus is returned to the fixed-share heirs (except the spouse) in proportion — this is radd.

    What this calculator does not cover

    It assumes every relative you enter is alive and eligible (e.g. not a non-Muslim heir or otherwise excluded). It does not handle distant kindred (dhawu'l-arham) where there are no fixed or residuary heirs, missing or unborn heirs, or contested questions where schools of thought differ. Debts, funeral costs and a bequest of up to one third should be settled before the estate is divided.

    Treat the result as a clear starting point for a conversation with a scholar, not a binding legal ruling.
