What Is a Home Equity Calculator?

A Home Equity Calculator estimates the portion of your home's current market value that remains after subtracting mortgages and other debts secured by the property.

It can also calculate your current loan-to-value ratio, equity percentage, and estimated additional borrowing capacity based on the maximum LTV percentage you choose.

Your home equity can change over time as your mortgage balance decreases or your property's market value changes.

Home Equity Formula

Home Equity = Home Value − Total Property-Secured Debt

Property-secured debt may include your primary mortgage, second mortgage, home equity loan, existing HELOC, or another debt secured by the property.

Loan-to-Value Formula

LTV = Total Property-Secured Debt ÷ Home Value × 100

LTV shows the percentage of your property's estimated value that is currently represented by secured debt.

Potential Borrowing Formula

Potential Borrowable Equity = (Home Value × Selected Maximum LTV) − Existing Property-Secured Debt

Home Equity Calculation Example

Suppose your home is currently estimated to be worth $450,000, while the remaining mortgage balance is $280,000.

Estimated Home Value: $450,000

Mortgage Balance: $280,000

Estimated Home Equity: $170,000

Equity Percentage: 37.8%

Current LTV: 62.2%

If you select an 80% maximum LTV, the estimated maximum total secured debt would be $360,000. After subtracting the existing $280,000 mortgage, the calculator would show approximately $80,000 in potential additional borrowing capacity.

What Can Affect Your Home Equity?

Mortgage Payments

Paying down your mortgage principal can gradually increase your equity if your property's market value remains stable.

Property Value Changes

If your home's market value increases, your estimated equity may increase. A decline in market value can reduce your equity.

Second Mortgages and HELOCs

Additional borrowing secured against your home increases total secured debt and can reduce the amount of equity available to you.

Home Improvements

Certain improvements may affect your property's market value, although renovation costs do not necessarily result in an equal increase in property value.

Home Equity vs. Borrowable Equity

Total home equity and borrowable home equity are not the same thing.

For example, you may have $170,000 of estimated equity in your property, but that does not necessarily mean you can borrow the full $170,000.

A lender may limit how much total property-secured debt can exist relative to your home's value. Income, credit, existing obligations, property valuation, and lender requirements can also affect borrowing eligibility.

Home Equity Calculator FAQs

Home equity is the estimated portion of your property's value that you own. It is calculated by subtracting mortgages and other debts secured by the property from the property's estimated current market value.
Subtract your outstanding mortgage balance and any other property-secured debt from your home's estimated market value. For example, a $450,000 home with $280,000 in secured debt has approximately $170,000 in equity.
Loan-to-value, or LTV, compares the amount of debt secured by your property with the property's estimated value. A lower LTV generally means you have a larger equity position.
Usually not. Lenders may require you to keep a certain amount of equity in your property. Borrowing limits can also depend on credit, income, debt, property value, lender requirements, and other factors.
Maximum LTV is the selected percentage of your property's value that may be represented by total property-secured debt. This calculator uses the selected LTV to estimate possible additional borrowing capacity.
No. This calculator provides estimates only. Actual loan approval, borrowing limits, property valuations, interest rates, fees, and eligibility requirements vary by lender.
