Islamic Inheritance Calculator (Mawarith/Faraid)
Estimate the distribution of an estate according to Islamic principles with this Islamic Inheritance Calculator.
Calculate Inheritance Shares
Enter the total value of the estate after all debts and funeral expenses are paid.
Disclaimer: This Islamic Inheritance Calculator provides an estimation based on common interpretations of Sunni Islamic law for the relatives included. Inheritance laws are complex and vary based on the school of thought (Madhhab) and specific circumstances. It does not account for all possible heirs, `Awl` (increase), `Radd` (return) in all complex scenarios, or bequests (Wasiyyah) beyond the calculator’s scope. Consult a qualified Islamic scholar or legal expert for accurate distribution in a specific case.
What is an Islamic Inheritance Calculator?
An Islamic Inheritance Calculator, also known as a Mawarith or Faraid calculator, is a tool designed to estimate the distribution of a deceased Muslim’s estate among their heirs according to the principles of Islamic law (Sharia). These principles are primarily derived from the Quran, and further elaborated in the Sunnah (teachings and practices of Prophet Muhammad, peace be upon him) and scholarly consensus (Ijma).
The Islamic system of inheritance (Ilm al-Mawarith or Ilm al-Faraid) is a detailed and fixed system that specifies the shares certain relatives are entitled to. The Islamic Inheritance Calculator aims to simplify the application of these rules for common scenarios.
Who Should Use It?
Anyone interested in understanding how an estate would be divided according to Islamic law can use an Islamic Inheritance Calculator. This includes:
- Individuals planning their estate and wanting to understand the default distribution.
- Family members wanting a preliminary idea of inheritance shares after a relative’s passing.
- Students of Islamic law or finance.
- Legal and financial professionals dealing with Muslim clients.
However, it’s crucial to remember that an Islamic Inheritance Calculator is an estimation tool and not a substitute for the ruling of a qualified Islamic scholar or judge, especially in complex cases or disputes.
Common Misconceptions
- It replaces a will: While an Islamic Inheritance Calculator shows the Sharia-defined shares, a will (Wasiyyah) is still important for bequests (up to 1/3 of the estate to non-heirs), appointing an executor, and clarifying debts.
- All relatives get equal shares: Islamic inheritance law assigns specific, different fractional shares to different relatives based on their relationship to the deceased and the presence of other heirs. It’s not an equal distribution.
- It covers everything: Basic calculators often don’t cover all complexities like `Awl` (proportionate reduction when shares exceed 1), `Radd` (distribution of surplus when shares are less than 1), or the shares of less common relatives. Our Islamic Inheritance Calculator attempts to address common heirs.
Islamic Inheritance Calculator Formula and Mathematical Explanation
The distribution in the Islamic Inheritance Calculator is based on the Quranic verses (primarily Surah An-Nisa, verses 11, 12, and 176) and Sunnah, which define the fixed shares for “Ashab al-Furud” (the heirs with fixed shares) and the portion for “Asabah” (residuary heirs).
The process generally involves:
- Identifying the surviving heirs.
- Assigning the fixed Quranic shares (Fard) to the Ashab al-Furud.
- Distributing the remainder, if any, to the Asabah (agnatic relatives, typically male line descendants, ascendants, and their collaterals).
Here are the shares for some common heirs considered by this Islamic Inheritance Calculator (simplified, assuming no `Awl` or complex `Radd` initially):
- Husband: 1/2 if no children or son’s children (h.l.s – how low soever), 1/4 otherwise.
- Wife/Wives: 1/4 if no children or son’s children (h.l.s), 1/8 otherwise (shared equally if more than one wife).
- Father: 1/6 if there are children or son’s children (h.l.s); 1/6 + residue if only daughters/son’s daughters; residue if no children/son’s children.
- Mother: 1/6 if there are children, son’s children (h.l.s), or two or more siblings; 1/3 of remainder after spouse’s share if no children/son’s children/multiple siblings AND father is present (Umariyyatayn); 1/3 of total otherwise.
- Daughter(s): 1/2 if one and no sons; 2/3 shared equally if two or more and no sons. If sons are present, daughters become Asabah with sons (2:1 ratio).
- Son(s): As Asabah, take the residue after fixed shares, and if daughters are present, they inherit together in a 2:1 ratio (son gets double daughter).
- Full Sister(s): 1/2 if one, no children, father, or brother; 2/3 if multiple under same conditions. Become Asabah with brothers or in presence of daughters without sons.
- Full Brother(s): Asabah, takes residue with sisters (2:1) or alone after fixed shares, if no son or father.
- Paternal Grandfather: Can substitute father if father is deceased, but with some different rules, especially regarding siblings.
- Maternal Grandmother: Can get 1/6 if mother is deceased and not blocked by nearer grandmother.
Our Islamic Inheritance Calculator implements these rules for the included relatives.

Practical Examples (Real-World Use Cases)
Example 1: Deceased Male with Wife, Sons, Daughters, and Parents
- Net Estate: $240,000
- Deceased: Male
- Surviving Heirs: Wife, 2 Sons, 3 Daughters, Father, Mother
Using the Islamic Inheritance Calculator:
- Wife’s share (with children): 1/8 = $30,000
- Father’s share (with children): 1/6 = $40,000
- Mother’s share (with children): 1/6 = $40,000
- Remaining for children: $240,000 – $30,000 – $40,000 – $40,000 = $130,000
- Children inherit as Asabah (2:1 for son:daughter). Total parts = (2*2) + (3*1) = 7 parts.
- Each son’s share: ($130,000 / 7) * 2 = ~$37,142.86
- Each daughter’s share: ($130,000 / 7) * 1 = ~$18,571.43
Example 2: Deceased Female with Husband, Mother, and Full Sisters
- Net Estate: $120,000
- Deceased: Female
- Surviving Heirs: Husband, Mother, 2 Full Sisters (no children, no father)
Using the Islamic Inheritance Calculator:
- Husband’s share (no children): 1/2 = $60,000
- Mother’s share (no children, but multiple siblings): 1/6 = $20,000
- Full Sisters’ share (two or more, no children, no father, no brother): 2/3 shared = $80,000
- Total fixed shares = 1/2 + 1/6 + 2/3 = 3/6 + 1/6 + 4/6 = 8/6. This is a case of `Awl` (increase), where the denominator increases to 8, and shares are adjusted proportionately. The calculator should ideally handle this or note it. In a simple normalization, Husband gets (3/8)*120000 = $45000, Mother (1/8)*120000 = $15000, Sisters (4/8)*120000 = $60000. Our calculator tries to handle basic scenarios first. Let’s see how our calculator handles it based on its logic.
How to Use This Islamic Inheritance Calculator
- Enter Net Estate Value: Input the value of the estate after settling all debts, funeral expenses, and any valid bequests (Wasiyyah – up to 1/3 to non-heirs, which is *not* automatically deducted by this calculator and should be handled before entering the net estate value if made).
- Select Deceased’s Gender: Choose male or female.
- Indicate Surviving Relatives: Use the dropdowns and number inputs to specify which relatives survived the deceased and their count (e.g., number of sons, daughters, brothers, sisters). Only include relatives listed.
- Calculate: Click the “Calculate Shares” button or observe real-time updates.
- Review Results: The Islamic Inheritance Calculator will display the primary distribution, intermediate shares, a table detailing each heir’s portion, and a pie chart.
- Understand the Disclaimer: Read the disclaimer carefully. This Islamic Inheritance Calculator is for educational and estimation purposes.
The results show the fraction and amount each group of heirs is entitled to based on the inputs and the rules programmed into the Islamic Inheritance Calculator.
Key Factors That Affect Islamic Inheritance Calculator Results
- Surviving Relatives: The presence or absence of certain relatives dramatically changes the shares of others. For example, children affect the spouse’s and parents’ shares.
- Gender of the Deceased: This can matter in specific situations, like the `Umariyyatayn` case involving parents and a spouse.
- Number of Heirs within a Group: One daughter gets 1/2, but two or more share 2/3 (if no sons).
- Presence of Male Counterparts: Daughters inherit differently if sons are present; sisters inherit differently if brothers are present.
- Debts and Funeral Expenses: These must be paid *before* the estate is distributed, reducing the net estate value entered into the Islamic Inheritance Calculator.
- Bequests (Wasiyyah): A valid bequest to non-heirs (up to 1/3 of the net estate after debts) is executed before the Faraid distribution. This calculator assumes the net estate is after Wasiyyah or none was made.
- School of Thought (Madhhab): While core principles are agreed upon, there are minor differences in interpretation among Sunni schools (Hanafi, Maliki, Shafi’i, Hanbali) and Shia jurisprudence, especially regarding more distant relatives or complex cases, which a simple Islamic Inheritance Calculator might not cover.
- `Awl` and `Radd`: If fixed shares sum to more than 1 (`Awl`), they are proportionately reduced. If less than 1 (`Radd`), the surplus may be redistributed to certain heirs in some schools of thought.
Frequently Asked Questions (FAQ)
- 1. What if the total shares calculated are more or less than 1?
- If fixed shares add up to more than 1, the case is called `Awl` (increase/reduction), and shares are reduced proportionally. If less than 1, the remainder might be distributed via `Radd` (return) to some heirs, or go to `Bayt al-Mal` (treasury) or more distant relatives depending on the Madhhab. This Islamic Inheritance Calculator handles very basic scenarios and may not fully implement complex `Awl` or `Radd` as per all schools.
- 2. Does the Islamic Inheritance Calculator account for Wasiyyah (bequests)?
- No, you should deduct the value of valid bequests (up to 1/3 of the estate after debts, to non-heirs) from the estate value *before* entering it into the “Net Estate Value” field of this Islamic Inheritance Calculator.
- 3. What about adopted children or step-children?
- In Islamic law, adopted children and step-children are not automatic heirs to the fixed shares. However, one can make a Wasiyyah (bequest) to them within the 1/3 limit, or gift assets during one’s lifetime (Hiba).
- 4. Can non-Muslims inherit from Muslims?
- Generally, under traditional Islamic law, non-Muslims do not inherit from Muslims through the fixed Faraid shares, and vice-versa, though a Wasiyyah can be made.
- 5. How are debts handled?
- All debts of the deceased, including funeral expenses, must be paid before any inheritance distribution or execution of bequests. The Islamic Inheritance Calculator uses the net estate value after these deductions.
- 6. What if there are multiple wives?
- If the deceased male had more than one wife, they share the wife’s portion (1/4 or 1/8) equally among themselves. Our Islamic Inheritance Calculator assumes one spouse but the share is for the ‘wife’ category.
- 7. Is this Islamic Inheritance Calculator based on a specific school of thought?
- This calculator is based on commonly accepted principles within Sunni Islam, covering the most direct heirs. For nuanced cases or differences between Madhhabs (Hanafi, Maliki, Shafi’i, Hanbali), consult a scholar.
- 8. What about unborn children?
- The share of an unborn child (if the pregnancy is established) is usually set aside until birth to determine their share based on their gender and whether they are born alive.
