Home Equity Calculator: Estimate Your Available Equity

Home equity is the portion of your home’s value that remains after subtracting the mortgage and other debt secured by the property. This calculator helps you estimate total home equity and see how much may be accessible under several combined loan-to-value, or CLTV, scenarios.

Enter your estimated home value and the total of your mortgage and lien balances. You can also enter a desired cash amount to compare that amount against the estimated accessible equity at 80%, 85%, and 90% CLTV.

The result is a planning estimate, not an appraisal, credit decision, loan offer, or provider quote. A lender or home equity provider may use a different property value, maximum CLTV, underwriting standard, fee structure, or product agreement.

Educational estimate only: This calculator is for planning and comparison. Actual accessible equity, loan terms, home equity investment proceeds, and provider eligibility vary by property, lender or provider, appraisal, existing liens, borrower profile, and location.

Use the results to understand the difference between equity you own and equity you may be able to access. If your estimated accessible equity is less than your desired cash amount, do not assume that you have no options; compare product structures, qualification requirements, and actual provider terms before making a decision.

How to use this home equity calculator

Start with an estimated current home value and your total mortgage and lien balances. Include your first mortgage, any existing home equity loan, and any outstanding HELOC balance.

The calculator shows:

• Your estimated current home equity.
• Your estimated equity percentage.
• Estimated accessible equity at 80%, 85%, and 90% CLTV scenarios.
• Whether your desired cash amount appears to fit within each illustrated scenario.

For example, if your home is worth $500,000 and you owe $300,000 across mortgages and liens, your estimated total equity is:

$500,000 − $300,000 = $200,000

If you use an 85% CLTV scenario, the tool estimates accessible equity by subtracting the $300,000 in secured debt from 85% of the $500,000 home value:

($500,000 × 85%) − $300,000 = $125,000

These examples are illustrations. They do not determine the value a lender or provider will use or the amount you will be approved to receive.

Home equity vs. accessible equity

Total home equity is the difference between your home’s estimated current value and the amount you owe on mortgages and other liens secured by the property.

Accessible equity, sometimes called tappable equity, is the portion of that equity that may remain after a lender or provider applies its own limits. A conventional lender may limit total secured debt to a maximum CLTV percentage. A home equity provider may use a different valuation and product-specific criteria.

That means you can have meaningful total equity but still have less equity available to access than you expect. For example, a homeowner with 40% total equity may not be able to borrow or receive the entire 40% because the lender or provider may require that some equity remain in the home.

If the result is below zero at a given CLTV scenario, the calculator displays $0 in estimated accessible equity for that scenario, even if it shows that you still have some total equity in the home.

If you want to estimate a potential revolving line amount, use the HELOC Calculator.

Why 80%, 85%, and 90% CLTV estimates differ

Combined loan-to-value, or CLTV, compares all debt secured by your home with its estimated value. It generally includes your first mortgage, any existing home equity debt, and the new HELOC or home equity loan amount you want to add.

The calculator shows three planning scenarios:

• 80% CLTV: A more conservative scenario that leaves more equity in the home.
• 85% CLTV: A common planning benchmark, but not a universal lender limit.
• 90% CLTV: A higher-access scenario that some borrowers may see, depending on lender, property, credit, income, occupancy, and other factors.

A higher CLTV can increase estimated accessible equity, but it can also mean less remaining equity and a larger amount secured by your home. Use the scenarios to understand sensitivity, not to assume that a lender will approve the highest number displayed.

Three ways homeowners may use accessible equity

Once you understand your estimated accessible equity, the next question is which structure fits the need, payment capacity, and timeline.

HELOC: flexible access over time

A HELOC is a revolving line of credit secured by your home. It can be useful when expenses occur over time, such as a phased renovation or an uncertain cash need. You generally pay interest on the amount you draw, and most HELOCs have variable rates and monthly payment obligations.

Use the HELOC Payment Calculator to estimate how a drawn balance, interest-rate assumptions, and repayment terms may affect a monthly payment.

Home equity loan: fixed payment for a lump sum

A home equity loan generally provides a lump sum and often has a fixed rate and fixed payment. It may be useful when you know the amount you need for a one-time expense and prefer predictable monthly payments.

For a local overview of this structure, read the Arizona home equity loan guide.

No-monthly-payment home-equity alternatives

Some homeowners want to access equity but cannot or do not want to take on a monthly payment. Depending on the homeowner’s age, property, financial profile, and goals, alternatives may include a home equity investment, a reverse mortgage, or another structure.

These options involve different risks, fees, eligibility standards, and repayment or settlement obligations. They are not automatically lower-cost than a HELOC or home equity loan. To learn more, explore home-equity options without monthly payments.

What can change your actual available equity

The calculator uses your estimates. Actual accessible equity may differ because of:

• A lender or provider’s appraisal, automated valuation, or other property-value method.
• Current mortgage, lien, HELOC, or home equity loan balances.
• Maximum CLTV or product-specific equity-retention rules.
• Credit, income, debt-to-income ratio, and ability-to-repay standards.
• Property type, condition, occupancy, and location.
• Minimum and maximum loan, line, or investment amounts.
• Fees, closing costs, existing lien payoff requirements, and title issues.
• Current lender or provider guidelines and state availability.

For that reason, use the calculator as a first estimate—not as a final measure of your equity or your eligibility.

How to use your estimate before applying

If you have estimated accessible equity, clarify the purpose of the funds and the payment obligation you can comfortably handle before applying.

Consider:

• Whether you need a lump sum or flexible access over time.
• Whether a variable payment fits your budget.
• Whether a fixed-rate home equity loan better matches a one-time expense.
• How long you expect to keep the financing in place.
• How a sale, refinance, or future move could affect the product.
• Whether the amount of equity you retain after closing feels appropriate.
• Fees, closing costs, and any early-closure or termination terms.
• Whether you have reviewed more than one lender or provider.

If you are comparing a HELOC with a home equity investment, use the HELOC vs. HEI Calculator.

Frequently asked questions

How do I calculate home equity?

Subtract the total of your mortgage and other liens secured by the home from the home’s estimated current value. For example, a $500,000 home with $300,000 in secured debt has an estimated $200,000 in total equity.

How much home equity can I access?

It depends on the lender or provider, property value, existing secured debt, product type, credit, income, debt-to-income ratio, occupancy, and other factors. This calculator shows illustrative accessible-equity scenarios at 80%, 85%, and 90% CLTV, not an approval amount.

What is the difference between home equity and accessible equity?

Home equity is the value you own after subtracting secured debt from your home’s value. Accessible equity is the amount that may remain after a lender or provider applies product-specific limits, such as a maximum CLTV or equity-retention requirement.

Is 20% equity enough for a HELOC?

It may be enough in some situations, but there is no universal rule. A lender may use a different maximum CLTV based on credit, income, property type, occupancy, location, line amount, and product guidelines. Your actual ability to access equity can be lower or higher than a simple percentage suggests.

Why is my accessible equity lower than my total home equity?

Lenders and providers typically do not allow homeowners to access all equity. A maximum CLTV, existing liens, fees, valuation differences, and underwriting standards can reduce the amount that is available.

Does an online home-value estimate determine my equity?

No. An online estimate can be a useful starting point, but a lender or provider may use an appraisal, automated valuation, broker price opinion, or another method. The value they use may differ from the estimate you enter.

Can I use home equity without a monthly payment?

Some alternatives may not require a monthly payment to the provider, but they can involve a future settlement obligation, lien, fees, eligibility requirements, or other tradeoffs. Review the full agreement and compare alternatives before choosing one.

Is this calculator a loan offer or home equity investment quote?

No. This calculator is an educational planning tool. It does not provide a loan offer, HELOC prequalification, credit approval, home equity investment quote, or provider-specific settlement estimate.

Methodology, limitations, and disclosures

This calculator estimates total home equity by subtracting mortgage and lien balances from estimated home value. It estimates accessible equity at fixed 80%, 85%, and 90% CLTV scenarios by subtracting secured debt from each of those percentages of estimated home value.

The calculator does not determine the property value a lender or provider will use, your credit qualification, income qualification, debt-to-income ratio, interest rate, payment, fees, product eligibility, or final proceeds.

The CLTV scenarios are educational planning assumptions, not lender promises or universal home equity standards. Actual terms and available equity may differ materially.
