About Inheritance Share Calculator

Intestate succession allocates the net estate — assets less debts, funeral expenses and administration costs — among a statutory class of heirs in fixed proportions, with children normally taking equal shares of the residue after the spouse's and any other prescribed shares.

Formulas

Residue for children

Children's pot = Net estate - Spouse's share - Other heirs' shares

Per child

Share per child = Children's pot / Number of children

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • Indicative estimate only. Fees, entitlements, limits and formulas vary by jurisdiction, statute, policy wording and the facts of the case. This is not legal, tax, insurance or financial advice — confirm with a qualified professional or the relevant authority.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Does a will override these shares?

Usually yes, subject to forced-heirship or family-provision rules that protect a spouse and dependent children in many jurisdictions.

What if a child predeceased the testator?

Most systems apply representation: that child's share passes down to their own children in equal parts.
