Read this before you use the result. This is an educational estimate, not a legal or religious determination. It covers only common, well-settled heir combinations under the Shafi'i school as applied in Malaysia, and it will refuse to calculate wherever the outcome is disputed, depends on which school or state applies, or needs a judicial finding of fact. Only the Syariah Court can issue a binding faraid determination.

It also assumes the estate figure you enter is already net: funeral expenses, debts and any bequest have been settled, and any jointly acquired property (harta sepencarian) has already been carved out. Those steps come first and they change the number the shares are calculated on.

Heirs in scope: spouse, father, mother, sons and daughters. Siblings, grandparents and grandchildren are deliberately out of scope, because admitting them brings in blocking chains and the grandfather-with-siblings dispute.
