What this Islamic inheritance calculator can calculate

This page is an educational Islamic inheritance estimator, rather than a country-specific probate or inheritance-tax calculator. It supports a surviving husband or up to four wives, sons, daughters and parents in a restricted set of Sunni family cases. Enter every surviving person in those categories.

The tool requires confirmation that no siblings, grandchildren, grandparents or other potentially relevant relatives are present. Cases involving those relatives, disputed relationships, a missing person, an unborn child, different religious eligibility or local statutory rules need a separate assessment. Do not omit someone merely to obtain a result.

Prepare the net estate before entering heirs

Enter an estate value after appropriate funeral expenses, debts and any legally and religiously valid bequest have been settled. This calculator does not approve a will, establish property ownership or decide whether a particular payment forms part of an estate.

Use the deceased person’s actual ownership share, rather than the full value of jointly owned property. Agree on a valuation date and currency. An estate worth 120,000 after deductions is the amount to divide, even if the gross assets were worth more.

Spouse and parent shares in the supported model

Quran 4:11–12 establishes key shares for children, parents and spouses. In the supported child cases, a husband starts with one quarter, while wives together start with one eighth. Without children, the spouse shares are one half for a husband and one quarter for wives. Multiple wives divide their collective share equally.

With children, the mother starts with one sixth. The father takes one sixth with sons; with daughters and no sons he can also take remaining residue. In the supported spouse-and-both-parents case without children, the mother receives one third of the residue after the spouse. These rules cannot be applied independently of the full family.

Children, remaining residue and share adjustments

When sons and daughters inherit the residue together, each son receives twice each daughter’s share of that residue. Without sons, one daughter begins with one half and multiple daughters together with two thirds. These are starting shares before any necessary adjustment.

If fixed shares exceed the estate, this model applies proportional reduction, known as awl. If daughters remain with no father or son to take residue, this model returns surplus proportionally to the blood heirs included in the calculation, excluding the spouse from that return. This radd convention is not universal across all schools and legal systems.

Inheritance example with a wife, parents and two children

Consider a net estate of 120,000, one wife, both parents, one son and one daughter, with no other relevant relatives. The wife receives 15,000; the mother 20,000; and the father 20,000. The remaining 65,000 goes to the children in a two-to-one ratio: approximately 43,333.33 to the son and 21,666.67 to the daughter.

The result table distinguishes the collective share of a group from the share per person. Rounded displayed amounts can differ by a small currency unit from the estate total; arrange any final rounding as part of an agreed distribution.

Why some inheritance cases return no result

A childless case without a surviving father is outside this version’s scope because the next entitled relatives must be assessed. Any other-relative or unconfirmed-family selection also stops the calculation. A husband cannot be selected together with wives.

This is a deliberate boundary, not a statement that excluded relatives receive nothing. Obtain a qualified scholarly and local legal assessment before transferring property or money. The calculator has not been independently certified by a scholar and produces no succession certificate.
