Islamic Inheritance (Wirasat) Calculator
Estimate Islamic inheritance shares (Faraid) for common family scenarios based on estate value. Free to use, no signup required for occasional use.
This is a general guide covering common family scenarios only, not a substitute for a qualified scholar's ruling on complex cases (multiple wives, wills, grandchildren, disputes, etc.).
What is the Inheritance / Wirasat Calculator (Islamic)?
The Inheritance / Wirasat Calculator is a free tool that estimates how an estate should be divided among surviving family members according to standard Islamic inheritance rules (Faraid). Islamic law prescribes fixed shares for close relatives such as a spouse, children, and parents, with the exact fractions depending on which relatives survive the deceased — for example, a wife's share changes depending on whether the couple had children, and a daughter's share differs when she inherits alongside a son versus alone. This calculator walks you through common family scenarios by asking who survives (spouse, sons, daughters, father, mother, brothers, sisters) and applies the standard fixed-share and residuary rules used in the majority of straightforward cases to estimate each heir's portion of the total estate value you enter. It is designed as an educational and planning aid for families going through estate distribution, not as a religious ruling. Islamic inheritance law includes many nuanced cases — such as multiple wives, grandchildren of a predeceased child, or specific sect-based differences — that a general calculator cannot fully capture, so this tool clearly displays a reminder that complex situations should be verified with a qualified Islamic scholar or Alim before final distribution.
How to use it
Begin by entering the total value of the estate to be divided. Then indicate which close relatives survived the deceased: whether there is a surviving spouse, and how many sons and daughters, followed by whether the deceased's father and mother are alive, and whether there are surviving brothers or sisters. The calculator applies the relevant fixed Quranic shares (such as a spouse's or parent's portion) first, then distributes any remaining residue among the children according to the standard 2:1 male-to-female ratio used in Faraid for sons and daughters inheriting together. Once you submit the family structure, you'll see a breakdown showing each heir's percentage share and their corresponding rupee (or currency) amount based on the estate value you entered. Because this tool covers common, straightforward scenarios only, treat the result as a starting estimate and consult a qualified Islamic scholar for cases involving multiple marriages, disinheritance disputes, wills (wasiyyah) exceeding one-third of the estate, or other complexities not captured here.
Frequently asked questions
Is this calculator a substitute for a scholar's ruling?
No. This tool provides a general estimate for common family scenarios only. Complex cases — multiple wives, predeceased heirs, wills, or disputes — should always be verified with a qualified Islamic scholar.
Why do sons and daughters get different shares?
Under Faraid, when sons and daughters inherit together as residuary heirs, the standard ruling gives a son twice the share of a daughter, reflecting differing financial responsibilities assigned in Islamic law.
Does this tool account for debts and funeral expenses?
No, Islamic inheritance law requires debts, funeral costs, and any valid will (up to one-third of the estate) to be settled before distribution — deduct these from the estate value yourself before entering it.
What if a family member is missing from the options?
This calculator covers the most common heirs — spouse, children, parents, and siblings. Estates involving grandchildren, aunts, uncles, or other extended relatives need a scholar's detailed calculation.
