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.
