Direct answer
Home equity is current property value minus secured balances, but usable proceeds may be lower after sale costs, taxes, liens, valuation uncertainty, and borrowing limits.
What this calculation tells you
The calculation estimates the owner's residual interest before or after explicitly entered costs.
It does not establish an accepted appraisal, legal ownership, available credit, or guaranteed sale proceeds.
Where it is used
Homeowners
Track value and secured debt.
Selling
Estimate proceeds after costs.
Borrowing
Understand leverage before considering a home-equity product.
Net-worth planning
Separate property equity from liquid assets.
When this guide helps
- Property value has changed.
- A mortgage balance has fallen.
- A sale is being considered.
- A home-equity loan or line is proposed.
Use a supportable value range
Automated estimates, asking prices, appraisals, and realized sale prices differ; test more than one value when the decision is sensitive.
Subtract every relevant claim and cost
Include secured balances, liens, early repayment charges, selling costs, and current local taxes where applicable and verified.
Do not confuse access with ownership
A lender may permit borrowing against only part of the equity, and the new debt adds payments and puts the property at risk on default.
Common mistakes
Before relying on home equity: value minus debt is only the starting point, test the stated assumptions and keep its decision boundary visible.
- Using the highest online estimate as certain.
- Calling gross equity sale proceeds.
- Treating a credit line as savings.
Worked case: gross equity
Entered property value is 500,000 and secured loan balance is 320,000.
500,000-320,000=180,000.
Gross entered equity is 180,000 before sale costs, tax or other liens.
The value is an estimate unless supported by the applicable valuation process.

Worked case: illustrative 80% combined-LTV cap
If a visitor enters an 80% maximum combined balance for screening, maximum debt is 400,000.
Potential additional amount=400,000-320,000=80,000 before fees and approval.
The arithmetic headroom is 80,000 under the entered cap.
The calculator does not supply a universal cap or guarantee access.

home equity: compare assumptions, not just answers
Equity, net sale proceeds and borrowable amount are distinct. Keep transaction costs, junior liens and underwriting separate.
| Scenario | Changed assumption | Result |
|---|---|---|
| Gross equity | 500,000 - 320,000 | 180,000 |
| Entered access screen | 80% cap | 80,000 headroom |

- Value date and basis stated
- All secured debt included
- Sale costs separate
- Access cap visitor entered
- No approval guarantee
Practical questions
Frequently asked questions
Can equity be negative?
Yes. Secured obligations and selling costs can exceed current property value.
Does paying principal increase equity?
All else equal it reduces debt, but property value and other secured claims can change simultaneously.
How much equity can I borrow?
That depends on lender, product, value, income, obligations, law, and underwriting; the article cannot determine it.
