Faraid Islamic Inheritance Calculator
Work out how an estate is divided under Islamic inheritance law once funeral costs, debts and bequests have been settled.
Settle the estate, then divide the balance
Funeral costs, then debts, then a bequest of up to one third — only what is left is shared among the fixed heirs.
Read this before you rely on any figure
This is a simplified illustration that covers the most common heir combinations only. It models a spouse, sons, daughters, a father and a mother, and nothing else. Many real situations are not modelled: grandparents, grandchildren and other descendants, brothers and sisters inheriting in their own right, half and consanguine siblings, uncles, aunts and distant kindred, heirs who are absent, missing, disqualified or who died in the same event, estates spread across several countries, and the differences between schools of law in how awl and radd adjustments are treated. Where those adjustments do apply here they are shown as explicit lines using the majority Sunni approach, which other schools handle differently. A qualified scholar or a Shariah court must confirm any actual distribution — do not distribute a real estate on the basis of this page.
Understanding Faraid
Four Claims, in Strict Order
Nothing reaches an heir until three earlier claims are met, and they are met in a fixed sequence.
- Funeral and burial costs come out first, at a reasonable and customary level
- Debts follow, including unpaid mahr, outstanding zakat and tax
- Wasiyyah (bequests) then take up to one third of what remains
- Faraid divides only the balance, and it cannot be waived by a will
Fixed Sharers and Residuaries
Heirs fall into two classes and they are paid in that order. Ashab al-furud hold a fraction named in the Qur'an: a husband's 1/4, a wife's 1/8, a parent's 1/6. Those fractions are taken off the top.
Whatever is left goes to the asabah, the residuaries. A son is the strongest residuary and displaces most others; a father becomes a residuary only when no son survives. The residue can be large or nothing at all, which is why a residuary heir's outcome swings so much with the family shape.
Blocking (Hajb) Changes the Answer
Presence of one relative can shrink or erase another's entitlement, so counting heirs is not enough.
- A son reduces a husband from 1/2 to 1/4 and a wife from 1/4 to 1/8
- A son locks the father at exactly 1/6 with no residue
- Two or more siblings cut the mother from 1/3 to 1/6 even though those siblings may inherit nothing themselves
- A son or a father blocks brothers and sisters completely; without both, siblings become heirs and this page can no longer model the estate
When the Fractions Do Not Sum to One
The named fractions were never guaranteed to total exactly the whole estate, and two corrections handle the gap.
- Awl: the fractions overshoot. A wife, two daughters and both parents claim 3/24 + 16/24 + 4/24 + 4/24 = 27/24. Every share is scaled down proportionally, so the denominator rises from 24 to 27 and the wife receives 3/27 instead of 1/8
- Radd: the fractions fall short and no residuary survives. The surplus is returned to the fixed sharers in proportion to their shares, but a spouse is excluded from the return
- The Umariyyatan cases (spouse, mother and father with no children) give the mother a third of the remainder after the spouse rather than a third of the whole
