Divorce Buyout Calculator — House Equity Buyout Estimate

Calculate the home equity buyout amount owed to a spouse in a divorce, with an optional notional selling-cost adjustment and refinance note.

Current Home Market Value ($)

Remaining Mortgage Balance ($)

Other Spouse's Ownership Share (%)

Apply notional selling-cost adjustment (optional)

Total Home Equity

$150,000

Buyout Amount Owed to Other Spouse

$75,000

Based on splitting the full home equity using a 50% share for the other spouse. Courts in equitable-distribution states do not have to use a 50/50 split — this percentage is adjustable to model any negotiated or court-ordered share.

Refinance note: to complete a buyout, the spouse keeping the home typically must either pay the buyout amount in cash or refinance the mortgage solely into their own name — removing the other spouse from the loan. Lenders qualify this new loan using only the buying spouse's individual income, credit, and debt-to-income ratio, so confirm refinance eligibility before relying on a buyout as the plan.

Home Equity = Current Market Value − Remaining Mortgage Balance. Buyout Amount = Equity (optionally reduced by a notional selling-cost adjustment) × the other spouse's ownership share. This calculator provides a starting-point estimate only — it is not legal or financial advice. Actual property division in a divorce depends on your state's law (community property vs. equitable distribution), any prenuptial or postnuptial agreement, and the discretion of the court or terms negotiated in a settlement. Always confirm numbers with a family law attorney or financial professional before finalizing a buyout.

Category	Range	What It Means	Status
Home Equity Formula ★	Current Market Value − Remaining Mortgage Balance	The starting point for any buyout calculation — get the market value from a recent appraisal or comparative market analysis, not a tax-assessed value, which often lags behind the real market.	★ Best
Default Ownership Split Assumption	50% / 50% (adjustable)	A 50/50 starting point is common, but it is not guaranteed — the actual split depends on state law, each spouse's financial contribution, and the discretion of the court or settlement negotiation.	Good
Notional Selling-Cost Adjustment	≈7–8% of home value	Some buyout methodologies subtract a hypothetical sale cost (≈5–6% realtor commission plus ≈1–2% closing costs) from equity before splitting, reasoning a real sale would have cost this money anyway — this makes the buyout fairer to the spouse keeping the house. It's an optional adjustment, not a legal requirement.	Okay
Community-Property States	9 states (AZ, CA, ID, LA, NV, NM, TX, WA, WI)	Marital property is generally split 50/50 by default, with less room for a judge to deviate from an equal division.	Good
Equitable-Distribution States	Remaining 41 states + DC	Property is divided "fairly," which does not have to mean equally — courts weigh each spouse's income, contributions (including non-financial, like homemaking), length of marriage, and other assets awarded.	Okay
Refinance Qualification for Buyout	Buying spouse's income/credit only	To remove the other spouse from the mortgage liability, the spouse keeping the home usually must refinance solely in their own name — the lender evaluates only that spouse's income, credit score, and debt-to-income ratio for approval.	Good

Worked Examples

Even 50/50 Split, No Selling-Cost Adjustment

Home Value: $400,000
Mortgage Balance: $250,000
Other Spouse's Share: 50%
Selling-Cost Adjustment: Off

$75,000 buyout owed

Equity = $400,000 − $250,000 = $150,000. Buyout = $150,000 × 50% = $75,000.

50/50 Split With a 7% Notional Selling-Cost Adjustment

Home Value: $500,000
Mortgage Balance: $300,000
Other Spouse's Share: 50%
Selling-Cost Adjustment: On, 7%

$82,500 buyout owed

Equity = $500,000 − $300,000 = $200,000. Notional selling cost = $500,000 × 7% = $35,000. Adjusted equity = $200,000 − $35,000 = $165,000. Buyout = $165,000 × 50% = $82,500.

Unequal Share Awarded by the Court (40%)

Home Value: $350,000
Mortgage Balance: $100,000
Other Spouse's Share: 40%
Selling-Cost Adjustment: Off

$100,000 buyout owed

Equity = $350,000 − $100,000 = $250,000. Buyout = $250,000 × 40% = $100,000 — a reminder that equitable-distribution states don't have to split equity evenly.

Higher 8% Selling-Cost Adjustment on More Equity

Home Value: $600,000
Mortgage Balance: $450,000
Other Spouse's Share: 50%
Selling-Cost Adjustment: On, 8%

$51,000 buyout owed

Equity = $600,000 − $450,000 = $150,000. Notional selling cost = $600,000 × 8% = $48,000. Adjusted equity = $150,000 − $48,000 = $102,000. Buyout = $102,000 × 50% = $51,000.

No Equity to Split (Underwater/Break-Even Mortgage)

Home Value: $275,000
Mortgage Balance: $275,000
Other Spouse's Share: 50%
Selling-Cost Adjustment: Off

$0 buyout owed

Equity = $275,000 − $275,000 = $0. Buyout = $0 × 50% = $0 — when the mortgage balance equals or exceeds the home's value, there is no equity for either spouse to buy out.

How to Use This Calculator

1

Enter the home's current market value

Use a recent appraisal or comparative market analysis — not the property tax assessed value, which is often outdated.
2

Enter the remaining mortgage balance

From your most recent mortgage statement.
3

Set the other spouse's ownership share

Defaults to 50%, but adjust it to reflect a negotiated split or a court-ordered percentage in an equitable-distribution state.
4

Optionally apply the notional selling-cost adjustment

Toggle it on and set a percentage (commission + closing costs, typically 7–8%) if you want the buyout to reflect what a real sale would have cost.
5

Read the buyout amount and refinance note

Shows total equity, the buyout owed, and a reminder that the buying spouse generally needs to refinance solely in their own name to complete the transfer.

What Each Value Means

Home Equity ($): The home's current market value minus the remaining mortgage balance — the total value available to divide between spouses.
Buyout Amount ($): The dollar amount one spouse pays (in cash or via refinancing) to the other spouse in exchange for their share of the home's equity.
Notional Selling-Cost Adjustment (% of home value): An optional deduction from equity, before splitting, representing the hypothetical cost of selling the home (realtor commission plus closing costs) — used to make the buyout fairer to the spouse keeping the house.

Frequently Asked Questions

How is a divorce house buyout amount calculated?

Start with home equity: current market value minus the remaining mortgage balance. Multiply that equity by the other spouse's ownership share — often 50%, but not always — to get the buyout amount. Some methodologies first subtract a notional selling cost (typically 7–8% of the home's value, covering a hypothetical realtor commission and closing costs) from the equity before splitting, since a real sale would have cost that money anyway.

Is the split always 50/50?

No. A 50/50 split is a common starting assumption, but it isn't guaranteed. In the nine community-property states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin), marital property is generally split evenly by default. In the other 41 states plus Washington DC — equitable-distribution states — courts divide property "fairly," which does not have to mean equally. Judges weigh each spouse's income, financial and non-financial contributions to the marriage, length of the marriage, and other assets each spouse is keeping. This calculator's ownership-share field is adjustable specifically so you can model any percentage, not just an even split.

What is the notional selling-cost adjustment, and should I use it?

It's an optional adjustment some buyout methodologies apply: before splitting the equity, you subtract a hypothetical cost of selling the home — typically 5–6% for a realtor commission plus 1–2% for closing costs, or roughly 7–8% combined. The reasoning is that if the couple had simply sold the house and split the proceeds instead of doing a buyout, those costs would have come out of the equity anyway. Using this adjustment tends to lower the buyout amount, which some see as fairer to the spouse keeping the house since they're avoiding those costs by not selling. Whether to use it is a negotiation point, not a legal requirement — some settlements use it, many don't.

Do I need to refinance the mortgage to complete a buyout?

In most cases, yes. Simply agreeing on a buyout amount doesn't remove the other spouse from the existing mortgage — their name stays on the loan (and their liability for it continues) until the loan is refinanced or paid off. The spouse keeping the home typically needs to refinance the mortgage solely into their own name, which the lender will approve based only on that spouse's individual income, credit score, and debt-to-income ratio. If that spouse can't qualify alone, a cash buyout without a full mortgage payoff, a delayed refinance, or selling the home outright may be the more realistic paths.

What if the buying spouse can't afford to pay cash or refinance?

This is one of the most common reasons a planned buyout falls through. Options include: negotiating a lower buyout amount using the notional selling-cost adjustment, trading other marital assets (retirement accounts, vehicles, savings) instead of cash for some or all of the buyout, structuring the buyout as payments over time rather than a lump sum (with terms spelled out in the divorce settlement), or ultimately selling the home and splitting the actual proceeds if refinancing and cash aren't feasible.
