Estate Equalization Calculator: When One Child Gets the Business
What may each child receive, and is there still a gap?
Compare what two children may receive and see what is still missing.
Start with the decision
What may each child receive, and is there still a gap?
One child will carry on the business. Another may want an inheritance they can use without depending on a sibling’s company. This estate equalization calculator compares the assets assigned to two children, the money still available, and the gap against your chosen shares. It helps make the family’s tradeoffs visible before documents are drafted.

01
How to read it
Choose the family outcome before choosing a funding method. Equal dollar values, equal ownership, and equal control are three different decisions.
A business interest may generate income but be difficult to sell. Compare debt, tax exposure, timing, and access to cash with the other child’s inheritance; this screen does not make those assets equivalent.
Use the gap to discuss alternatives with your estate attorney and CPA: other assets, a funded buyout, a note with realistic payments, insurance where appropriate, or an intentionally unequal plan that the family understands.
02
What could change the answer
Valuing a closely held business, deciding a defensible discount, or judging which allocation is fair
Estate, gift, income, or capital-gain taxes, debt, transaction costs, and the after-tax value of each asset
Buy-sell terms, note payments, voting rights, trusts, special needs, or enforceability of estate documents
More than two children, future business growth, or the family’s changing cash needs
03
What to take forward
Ask your attorney and CPA whether the family means equal value, equal liquidity, or equal control—and whether the proposed assets can deliver that outcome.

How the estimate works
See how the estimate is calculated
Enter the total estate, including the business and assets already assigned to either child. Do not count those assigned assets twice. Enter the target percentage for the first child; the second receives the remaining percentage.
The model adds insurance payable to the second child outside the entered estate, then calculates both target shares against that combined pool. Any business-value adjustment reduces the first child’s credited allocation; it does not reappraise the entire estate.
For each child, subtract the credited allocation from the target and floor the shortfall at zero. Subtract available unassigned estate assets from the combined shortfalls. A positive remainder is the amount the current design still cannot fund.
Common questions
Frequently asked questions
What is estate equalization when one child inherits the business?
It means coordinating the business transfer with the rest of the estate so each beneficiary receives the intended economic share. The active child may receive the business while siblings receive cash, investments, property, insurance proceeds, or a properly structured payment obligation. Equalization does not require giving every child business ownership.
Does equal inheritance mean equal ownership of the business?
No. Ownership, voting control, and economic value can be separated, subject to the governing documents and tax rules. A sibling who does not work in the company may prefer liquid assets rather than a minority interest with limited control or an uncertain exit.
How does the $10 million business example work?
With a $14 million estate and a 50/50 goal, each child’s target is $7 million. Assigning a $10 million business to one child leaves $4 million for the other and a $3 million gap against the original target. Either $3 million of business-child value must move to the other child, or $6 million of new outside resources is needed if the first child keeps all $10 million.
Can life insurance close the equalization gap?
It can supply resources, but adding proceeds also increases the combined pool used for the percentage targets. Recalculate both shares after adding insurance. Separately review ownership, beneficiaries, premiums, underwriting, and estate-tax treatment with the professionals responsible for the plan.
What belongs in the total estate input?
Include the business and all other estate assets being modeled, including amounts you enter as already assigned to either child. The calculator subtracts those assignments to find unassigned assets. Enter outside-estate insurance for the second child in its separate field only, so it is not counted twice.
What should we bring to a family succession meeting?
Bring the business valuation and ownership documents, a list of assets and debts, beneficiary designations, insurance details, the intended shares, and any promises already made to either child. Note which assets can provide cash and when. Have the attorney and CPA test the assumptions and implementation before making transfers.
