Faraid Calculator (Simplified Sunni Model)
This tool estimates estate distribution for common heirs: spouse, father, mother, sons, and daughters. It applies debt/funeral deductions and caps bequests at one-third.
Family Inputs
Important: This is an educational calculator, not a fatwa. Real inheritance can vary by madhhab, surviving relatives, local law, and specific case facts.
How This Islamic Inheritance Law Calculator Works
Islamic inheritance law (faraid) is a rules-based system that assigns defined shares to eligible heirs. Before any distribution happens, the estate is processed in order: funeral expenses, debts, then valid bequests (wasiyyah up to one-third), and finally distribution among heirs.
Core sequence used in this calculator
- Start with gross estate value.
- Subtract debt and funeral costs.
- Cap bequest at one-third of the post-debt balance.
- Distribute the remainder to heirs using fixed and residual shares.
What Heirs Are Included
This calculator focuses on high-frequency family structures and includes:
- Husband or wives
- Mother
- Father
- Sons
- Daughters
These are often enough for practical estimates, but complete mirath calculations may require siblings, grandparents, grandchildren, and other relatives when present.
Share Logic Used (Simplified)
Spouse shares
- Husband: 1/2 if no descendants, 1/4 if descendants exist.
- Wife/Wives: 1/4 if no descendants, 1/8 if descendants exist (shared equally among wives).
Parents
- Mother: 1/6 with descendants, otherwise 1/3 (simplified assumption).
- Father: 1/6 with descendants; otherwise residue. If only daughters exist, father can absorb residue after fixed shares.
Children
- If sons and daughters both exist: remainder is distributed with a 2:1 male-to-female ratio.
- If only daughters exist: one daughter gets 1/2; two or more daughters share 2/3.
Awl and Radd in Plain Language
Sometimes fixed shares exceed 100% of the estate. In that case, the calculator applies awl, a proportional reduction of fixed shares. In other cases, leftover estate can be returned to eligible heirs (radd) in simplified form when no residuary heir is available in this model.
Practical Example
Suppose the estate is 300,000, debts are 30,000, funeral expenses are 10,000, and bequest is 120,000. The calculator first reduces the estate to 260,000 after debts and funeral. The bequest cap is one-third (86,666.67), so only that amount is applied. The distributable inheritance then becomes 173,333.33.
From there, heirs receive shares according to the selected family structure. The result table shows total share, percentage, and individual amount where applicable.
Why Use a Calculator First
- Get a quick estimate before speaking with scholars or legal professionals.
- Model multiple scenarios by changing family inputs.
- Identify whether shares are fixed, residual, or adjusted by awl.
Important Limitations
- Not a replacement for qualified Islamic scholarship.
- Does not include all heir classes or exclusion rules (hajb).
- Does not account for jurisdiction-specific probate rules.
- Some complex parent-spouse configurations are simplified.
Final Note
Use this Islamic inheritance law calculator as an educational planning tool. For real estate settlement, confirm all numbers with a qualified mufti/scholar and a legal advisor in your jurisdiction. That combination gives both Shariah accuracy and legal enforceability.
