About this calculator
The Inheritance Split Calculator estimates how a net estate could be divided between beneficiaries after debts, funeral costs, estimated inheritance tax, fixed gifts, percentage shares, and equal shares. It is designed for planning conversations and executor-style checks, not as legal advice.
Estate split method
The calculator starts with gross estate value, subtracts estate costs, applies fixed gifts first, then percentage shares, then splits any remaining balance equally between selected beneficiaries.
- net estate = gross estate - inheritance tax - debts - funeral costs
- remainder after fixed gifts = net estate - fixed gifts
- percentage gift = remainder after fixed gifts x beneficiary percentage
- equal share = remaining balance / number of equal-share beneficiaries
How to use the inheritance split calculator
- Enter the gross estate value before tax and costs.
- Enter estimated inheritance tax if you already have a separate estimate.
- Enter debts, executor costs, and funeral costs.
- Add each beneficiary name.
- Enter fixed gifts first where the will gives a specific amount.
- Enter percentage gifts where the will gives a stated percentage.
- Tick equal share for beneficiaries who split whatever remains.
Inheritance split examples
Two equal beneficiaries
Input: Net estate GBP 300,000 and two equal beneficiaries.
Calculation: GBP 300,000 / 2.
Result: Each beneficiary receives GBP 150,000 before any personal tax or administration issues.
Fixed gift first
Input: Net estate GBP 300,000, fixed gift GBP 20,000, two equal remainder beneficiaries.
Calculation: Remainder GBP 280,000 split equally.
Result: The fixed beneficiary receives GBP 20,000 and each remainder beneficiary receives GBP 140,000.
Why fixed gifts come first
Many wills leave specific sums or items before the remainder of the estate is divided. If the estate is smaller than expected, fixed gifts can reduce the amount left for percentage or equal-share beneficiaries.
Issues the calculator cannot decide
- Will interpretation
- Only the will, codicils, and legal advice can decide exactly how clauses should be interpreted.
- Joint assets
- Some jointly owned assets may pass outside the will depending on ownership type.
- Trusts and lifetime gifts
- Trusts, gifts, and tax reliefs can change the estate available for distribution.
Records to gather
A practical estate estimate normally needs property valuations, mortgage statements, bank balances, investment and pension paperwork, debts, funeral invoices, and tax estimates. Missing information can materially change the split.
Common mistakes
- Splitting the gross estate before debts and costs are removed.
- Ignoring fixed gifts before calculating remainder shares.
- Including assets that pass outside the will.
- Treating the result as legal advice.
Limitations
This guide is general information only and is not legal, tax, or financial advice. Estate administration, wills, trusts, jointly owned assets, disputes, and tax rules can change the result.
Frequently asked questions
Does this calculate inheritance tax?
It accepts an estimated IHT amount. Use a dedicated inheritance tax calculation or professional advice for the tax figure.
Do fixed gifts always come first?
Often, but the wording of the will matters. The calculator uses a common planning order, not a legal interpretation.
Can beneficiaries receive different percentages?
Yes. Enter each percentage share and the calculator applies it to the remainder after fixed gifts.
What if percentages exceed 100%?
The calculator caps the allocation for estimation, but an over-allocated will needs legal interpretation.
Are pensions included?
Some pension death benefits may pass outside the estate. Check the scheme rules and nominations.
