How the Inheritance Calculator Calculates Results
An inheritance calculator distributes a deceased person's estate among heirs according to legal or Islamic fractional shares, after debts, bequests and funeral costs are settled first. It converts each heir's fraction into a currency amount. At its core the tool evaluates Heir share = estate ÷ denominator × heir numerator. On a 480,000 estate with a wife and three children, the wife receives 1/8 (60,000) and the remaining 420,000 splits 2:1 between one son and two daughters — 210,000 to the son and 105,000 to each daughter. Adjust any field and the outputs recompute immediately, so you can test as many scenarios as you like in the units you prefer.
