Free Assumption Calculator

Home Equity & Buyout Calculator™

Explore how an assumed home value, mortgage balance, liens, transaction costs, and division percentage can affect estimated equity and a potential buyout amount.

This calculator does not determine legal ownership or what either spouse is entitled to receive. It is designed to help you test financial assumptions and understand the math behind a possible home-equity discussion.

Enter Your Assumptions

Use estimates if exact figures are not yet available. You can change any number and calculate again.

Estimated Home Value

Use the value you want to test—not necessarily a formal appraisal.

Mortgage Balance

Enter the current estimated unpaid principal balance.

Other Liens Against the Home

Examples may include a HELOC or other debt secured by the property.

Assumed Selling Costs (%)

Set to 0 if you do not want hypothetical selling costs included.

Assumed Other Spouse Share (%)

This is only an assumption for comparison—not a legal determination.

Credits / Adjustments to Buyout

Optional. Positive amounts increase the estimated buyout; negative amounts reduce it.

Estimated Results

Results update when you select Calculate Assumptions.

Gross Equity Before Selling Costs $0

Assumed Selling Costs $0

Estimated Net Equity $0

Assumed Other Spouse Equity Share $0

Estimated Buyout Amount $0

How the estimate is calculated:
Home value − mortgage − other liens = gross equity.
Gross equity − assumed selling costs = estimated net equity.
Net equity × assumed share percentage ± optional adjustments = estimated buyout.

A buyout figure is only one part of the larger financial picture. Financing ability, taxes, refinancing requirements, property characterization, credits, offsets, transaction costs, and other assets may materially change the real-world result.

What this calculator can help you think about

Home-equity discussions often become confusing because people may be using different assumptions about value, debt, selling costs, percentage shares, or credits. This tool allows you to make those assumptions visible.

What happens if the home's assumed value changes?
How much equity remains after mortgage debt and other liens?
How different assumed selling costs affect net equity.
How a different assumed division percentage changes a possible buyout.
Why an estimated buyout amount is not the same thing as determining legal entitlement.
