Inheritance calculator

Choose the deceased’s heirs and the estate is divided in exact fractions, not decimals — with the reason each heir received their share, and why anyone excluded was excluded.

Choose the relatives who were alive on the day the deceased died. Where a number applies, raise it with + and lower it with −; where it does not, tick the box. The division appears at once and updates with every choice — there is no calculate button.

Spouse

Whichever spouse was alive on the day of death. Their share is reduced if the deceased left a child or a son’s child.

Number of wives

If the deceased was a woman choose “left a husband”; if a man, “left a wife”. The two never occur together.

Ascendants

Parents and those above them. “Grandfather” here means the father’s father; the mother’s father is a distant relative (dhawū al-arḥām), listed at the foot of this page.

Descendants

Children and a son’s children. A daughter’s children are not heirs of this class — they belong with the distant kindred.

Son
Daughter
Son’s son
Son’s daughter
Son’s son’s son
Son’s son’s daughter

Siblings

Siblings by all three lines: full, paternal, and maternal. Which line they belong to changes the whole division.

Full brother
Full sister
Paternal half-brother
Paternal half-sister
Maternal half-brother
Maternal half-sister

Agnatic relatives

The remoter agnates: they inherit only when no nearer one remains. Their order in this list is their order of entitlement.

Full brother’s son
Paternal brother’s son
Full paternal uncle
Paternal half-uncle
Full uncle’s son
Half-uncle’s son
Great-uncle (father’s father’s full brother)
Great-uncle (father’s father’s paternal half-brother)

Distant kindred (dhawu al-arham)

They inherit only when no blood relative with a fixed share and no agnatic heir remains. A spouse neither bars them nor has their own share reduced by them.

The full reference manual — for scholarly review The basis of division, the tables of shares and exclusion, the test results and the references — in one printable document.

Learn the division

Three sections for whoever wants to understand, not only to compute: the vocabulary of division, worked examples produced by the engine itself, and the inheritance verses with their commentary.

The vocabulary — what it means

These words appear in the calculator’s result, so each is explained by what it does, not by its name.

Fixed share (fard)
A fixed portion that neither grows nor shrinks — a half, a quarter, an eighth, two thirds, a third, a sixth. Those entitled to it are served first.
Residuary (ta’sib)
Taking whatever remains after the fixed shares. If nothing remains, the residuary takes nothing; if there is no fixed-share heir, he takes everything.
Exclusion (hajb)
One heir barred by a nearer one. Two kinds: total exclusion, which drops him entirely, and partial, which reduces his share — as the mother’s share falls from a third to a sixth when there is a child.
Base of the problem (asl)
The smallest number from which every share comes out whole. Instead of “the wife gets an eighth”, one says “she gets 3 of 24” — which is easier when actually dividing.
Increase (awl)
When the fixed shares exceed the estate, everyone’s share is reduced in the same proportion, so none is preferred over another. This is the majority position and what Egyptian law applies; Ibn Abbas differed.
Return (radd)
The inverse of awl: if something remains and there is no residuary to take it, it is returned to the fixed-share heirs in proportion to their shares — but not to a spouse while another heir is present. If a spouse is alone with no other heir, Egyptian law returns it to them (art. 30).
Unit share (sahm)
An heir’s share expressed as a count out of the base rather than as a fraction. It is what goes on the division sheet, because it divides without fractions.
Distant kindred (dhawu al-arham)
Any relative who is neither a fixed-share heir nor a residuary — a daughter’s daughter, a sister’s son, a maternal uncle. They inherit only when there is no blood fixed-share heir and no residuary. Their inheritance is the position of Abu Hanifa and Ahmad, and article 31 of the Egyptian inheritance law.
Kalala
That a person dies leaving neither child nor parent. The closing verse of Surat an-Nisa was revealed about it, on the inheritance of brothers and sisters.
Completing the two thirds
When a daughter takes a half, a son’s daughter takes a sixth so the daughters’ portion completes two thirds. If the deceased left two daughters they exhaust the two thirds, and the son’s daughter gets nothing.
Eight worked examples

The shares, unit shares, bases and reason texts in these examples are produced by the engine itself when the page is built — not written by hand. So no example here can say something the calculator above contradicts. The commentary under each is ours, and every ruling in it is attributed to its school.

A wife, a son and a daughter

A man died leaving a wife, a son and a daughter.

Base of the problem 8 exact

Wife 1/8 Fixed share: 1/8
Son 7/12 Residuary — takes what remains after the fixed-share heirs
Daughter 7/24 Residuary — takes what remains after the fixed-share heirs

What this teaches: The wife has a fixed share; the two children are residuaries taking what remains — the male taking twice the female's portion. The daughter takes no fixed half: her brother made her a residuary with him, so the two divide the remainder.

A husband, two daughters and a father — with increase (awl)

A woman died leaving a husband, two daughters and a father.

Base of the problem 12 increased (awl)

Husband 3/13 Fixed share: 1/4 before awl
Daughter × 2 4/13 Fixed share: 2/3 before awl
Father 2/13 Fixed share: 1/6 before awl

• The problem increased by awl: the fixed shares exceeded the whole, so it was divided in proportion to the portions.

What this teaches: The fixed shares came together to more than the estate, so everyone's share was reduced in the same proportion — that is the increase of the shares (awl). It is the position of the majority of the jurists and what Egyptian law applies; Ibn Abbas differed.

A husband, a full sister and a mother

A woman died leaving a husband, a full sister and a mother.

Base of the problem 6 increased (awl)

Husband 3/8 Fixed share: 1/2 before awl
Mother 1/4 Fixed share: 1/3 before awl
Full sister 3/8 Fixed share: 1/2 before awl

• The problem increased by awl: the fixed shares exceeded the whole, so it was divided in proportion to the portions.

What this teaches: The mother took the full third, because there is no inheriting descendant and no two or more siblings. The case then went to awl — the increase of the shares — and all three shares were reduced.

A daughter, a son's daughter and a full sister

A man died leaving a daughter, a son's daughter and a full sister.

Base of the problem 6 exact

Daughter 1/2 Fixed share: 1/2
Son’s daughter 1/6 Fixed share: 1/6
Full sister 1/3 Residuary — takes what remains after the fixed-share heirs

• The sisters are residuaries with the daughters and take what remains.

What this teaches: The son's daughter took the sixth, completing the two thirds after the daughter's half. The full sister became a residuary with the daughters and took what remained — she has no fixed share here.

A husband and both parents — the two Umariyya cases

A woman died leaving a husband, a father and a mother.

Base of the problem 6 exact

Husband 1/2 Fixed share: 1/2
Mother 1/6 A third of what remains after the spouse’s share (the two ʿUmariyya cases) — that is 1/6 of the estate
Father 1/3 Residuary — takes what remains after the fixed-share heirs

• The two ʿUmariyya cases: the mother takes a third of what remains after the spouse’s fixed share.

What this teaches: The mother takes a third of what remains after the husband's fixed share, not a third of the estate — otherwise the mother would be preferred over the father in a case in which the two are equal. This was the judgment of Umar (may Allah be pleased with him), and the majority hold it; Ibn Abbas differed.

A daughter alone — the return (radd)

A man died leaving one daughter and no other heir with her.

Base of the problem 2 deficient, with radd

Daughter 1 Fixed share: 1/2

• The residue was returned to the fixed-share heirs in proportion to their shares; nothing is returned to a spouse.

What this teaches: Her fixed share is the half, and no residuary remained to take the rest — so it was returned to her. The return (radd) is the position of Abu Hanifa and Ahmad, and what Egyptian law applies; nothing is returned to either spouse.

A daughter's daughter alone — the distant kindred

A woman died leaving a daughter's daughter and no other heir with her.

Base of the problem 1 to the distant kindred

Daughter’s daughter 1 Distant kindred — there is no fixed-share heir by blood and no residuary, so the remainder is theirs

• There is no fixed-share heir by blood and no residuary, so the remainder goes to the distant kindred by the method of kinship.

What this teaches: She is neither a fixed-share heir nor a residuary, but she is one of the distant kindred. Were it not for inheritance by the distant kindred, the case would have been declared «لا وارث» — an estate with no heir — although an heir does exist who is entitled to the whole estate. So article 31 of law 77 of 1943 provides.

Al-Mushtaraka — the schools differ on it

A woman died leaving a husband, a mother, two maternal half-brothers and a full brother.

Egypt

Base of the problem 6 exact

Husband 1/2 Fixed share: 1/2
Mother 1/6 Fixed share: 1/6
Maternal half-brother × 2 1/6 Among the uterine siblings — their fixed share is 1/3, divided equally: the male does not take twice the female’s portion here
Full brother — Nothing remained after the fixed-share heirs

• Al-Mushtaraka: the fixed-share heirs took the whole estate, so nothing remained for the full brothers — this is the view of Ali, Ubayy and Abu Musa, and the position of Abu Hanifa and Ahmad. On the view of Umar, Uthman and Zayd they share equally with the mother's children in the third.

• Withheld — whether Egyptian law adopts the joining in al-Mushtaraka: what is transmitted from article 10 conflicts with what is inferred from its silence. The difference is 0 or 1/9 for the full brother.

Zayd b. Thābit

Base of the problem 18 exact

Husband 1/2 Fixed share: 1/2
Mother 1/6 Fixed share: 1/6
Maternal half-brother × 2 1/9 Al-Mushtaraka — sharing the third equally: 2/9
Full brother 1/9 Al-Mushtaraka — sharing the third equally: 1/9

• Al-Mushtaraka: the full brothers were joined with the mother's children equally in the third (the view of Umar, Uthman and Zayd).

What this teaches: Here the two schools diverge over the full brother's share: he takes nothing on the view of Ali and the school of Abu Hanifa and Ahmad (which is the Egyptian setting on this page), and he is joined with the uterine siblings in the third on the view of Umar, Uthman and Zayd. So switch the school in the calculator and see the difference.

The three inheritance verses

The text is from this site’s Uthmani index; the explanation is the text of Tafsir al-Muyassar, word for word and attributed to its authors. We write no commentary of our own on the Quran.

The fixed shares of children and parents

يُوصِيكُمُ ٱللَّهُ فِىٓ أَوْلَٰدِكُمْ ۖ لِلذَّكَرِ مِثْلُ حَظِّ ٱلْأُنثَيَيْنِ ۚ فَإِن كُنَّ نِسَآءًۭ فَوْقَ ٱثْنَتَيْنِ فَلَهُنَّ ثُلُثَا مَا تَرَكَ ۖ وَإِن كَانَتْ وَٰحِدَةًۭ فَلَهَا ٱلنِّصْفُ ۚ وَلِأَبَوَيْهِ لِكُلِّ وَٰحِدٍۢ مِّنْهُمَا ٱلسُّدُسُ مِمَّا تَرَكَ إِن كَانَ لَهُۥ وَلَدٌۭ ۚ فَإِن لَّمْ يَكُن لَّهُۥ وَلَدٌۭ وَوَرِثَهُۥٓ أَبَوَاهُ فَلِأُمِّهِ ٱلثُّلُثُ ۚ فَإِن كَانَ لَهُۥٓ إِخْوَةٌۭ فَلِأُمِّهِ ٱلسُّدُسُ ۚ مِنۢ بَعْدِ وَصِيَّةٍۢ يُوصِى بِهَآ أَوْ دَيْنٍ ۗ ءَابَآؤُكُمْ وَأَبْنَآؤُكُمْ لَا تَدْرُونَ أَيُّهُمْ أَقْرَبُ لَكُمْ نَفْعًۭا ۚ فَرِيضَةًۭ مِّنَ ٱللَّهِ ۗ إِنَّ ٱللَّهَ كَانَ عَلِيمًا حَكِيمًۭا

يوصيكم الله ويأمركم في شأن أولادكم: إذا مات أحد منكم وترك أولادًا: ذكورًا وإناثًا، فميراثه كله لهم: للذكر مثل نصيب الأنثيين، إذا لم يكن هناك وارث غيرهم. فإن ترك بنات فقط فللبنتين فأكثر ثلثا ما ترك، وإن كانت ابنة واحدة، فلها النصف. ولوالِدَي الميت لكل واحد منهما السدس إن كان له ولد: ذكرًا كان أو أنثى، واحدًا أو أكثر. فإن لم يكن له ولد وورثه والداه فلأمه الثلث ولأبيه الباقي. فإن كان للميت إخوة اثنان فأكثر، ذكورًا كانوا أو إناثًا، فلأمه السدس، وللأب الباقي ولا شيء للإخوة. وهذا التقسيم للتركة إنما يكون بعد إخراج وصية الميت في حدود الثلث أو إخراج ما عليه من دَيْن. آباؤكم وأبْناؤكم الذين فُرِض لهم الإرث لا تعرفون أيهم أقرب لكم نفعًا في دنياكم وأخراكم، فلا تفضلوا واحدًا منهم على الآخر. هذا الذي أوصيتكم به مفروض عليكم من الله. إن الله كان عليمًا بخلقه، حكيمًا فيما شرعه لهم.

The fixed shares of the spouses and the maternal siblings

ولكم -أيها الرجال- نصف ما ترك أزواجكم بعد وفاتهن إن لم يكن لهن ولد ذكرًا كان أو أنثى، فإن كان لهن ولد فلكم الربع مما تركن، ترثونه من بعد إنفاذ وصيتهن الجائزة، أو ما يكون عليهن من دَيْن لمستحقيه. ولأزواجكم - أيها الرجال - الربع مما تركتم، إن لم يكن لكم ابن أو ابنة منهن أو من غيرهن، فإن كان لكم ابن أو ابنة فلهن الثمن مما تركتم، يقسم الربع أو الثمن بينهن، فإن كانت زوجة واحدة كان هذا ميراثًا لها، من بعد إنفاذ ما كنتم أوصيتم به من الوصايا الجائزة، أو قضاء ما يكون عليكم من دَيْن. وإن مات رجل أو امراة وليس له أو لها ولد ولا والد، وله أو لها أخ أو أخت من أم فلكل واحد منهما السدس. فإن كان الإخوة أو الأخوات لأم أكثر من ذلك فهم شركاء في الثلث يقسم بينهم بالسوية لا فرق بين الذكر والأنثى، وهذا الذي فرضه الله للإخوة والأخوات لأم يأخذونه ميراثًا لهم من بعد قضاء ديون الميت، وإنفاذ وصيته إن كان قد أوصى بشيء لا ضرر فيه على الورثة. بهذا أوصاكم ربكم وصية نافعة لكم. والله عليم بما يصلح خلقه، حليم لا يعاجلهم بالعقوبة.

Al-Kalala: the sisters and the brothers

An-Nisaa · 176

Tafsir · in Arabic — Tafsir al-Muyassar, King Fahd Complex

يسألونك -أيها الرسول- عن حكم ميراث الكلالة، وهو من مات وليس له ولدٌ ولا والد، قل: الله يُبيِّن لكم الحكم فيها: إن مات امرؤ ليس له ولد ولا والد، وله أخت لأبيه وأمه، أو لأبيه فقط، فلها نصف تركته، ويرث أخوها شقيقًا كان أو لأب جميع مالها إذا ماتت وليس لها ولد ولا والد. فإن كان لمن مات كلالةً أختان فلهما الثلثان مما ترك. وإذا اجتمع الذكور من الإخوة لغير أم مع الإناث فللذكر مثل نصيب الأنثيين من أخواته. يُبيِّن الله لكم قسمة المواريث وحكم الكلالة، لئلا تضلوا عن الحقِّ في أمر المواريث. والله عالم بعواقب الأمور، وما فيها من الخير لعباده.

What this calculator does not compute

The calculator divides by the fixed shares alone. These are seven cases it neither knows nor asks about — if your case is one of them, this page’s division is not enough for you:

  • The obligatory bequest — Whoever’s father died before his grandfather does not inherit from the grandfather by the fixed shares — yet Egyptian law (articles 76 onward) assigns him an obligatory bequest. This is the most common case of all, and this page does not compute it.
  • An unborn child — If an unborn child is among the heirs, a share is set aside and the estate is not finally divided until it is born.
  • A missing heir — One who is absent and not known to be alive or dead has a special ruling; his share is held until his case becomes clear.
  • Successive deaths — When an heir dies before the first estate is divided, two divisions interlock. This page computes one division only.
  • A killer — One who kills the person he inherits from is barred. The calculator does not ask about this, so if you enter him as an heir it will compute a share for him.
  • Difference of religion — There is no inheritance between a Muslim and a non-Muslim according to the majority. The calculator does not ask the heir’s religion.
  • Simultaneous deaths — When a group dies in one incident and it is not known who died first — a case in which the jurists differ in detail.

If your case is one of these, or the heirs disagree, or the estate includes an endowment or a partnership — consult a specialist or the competent court. This page is a calculating tool, not a fatwa.

Shares are exact fractions, not decimals, so nothing of the estate is lost. Any money figure shown is an approximation for display only.
