Calculate your home equity, loan-to-value ratio, and usable equity
Home equity represents the financial stake you have in your property. It is the difference between your home's current fair market value and the total amount you still owe on all mortgages and liens secured by the property. As you make monthly mortgage payments and as your property appreciates in value, your home equity grows over time.
Understanding your home equity is essential for making informed financial decisions. Whether you are considering a home equity loan, a home equity line of credit (HELOC), refinancing your mortgage, or planning to sell your home, knowing exactly how much equity you have—and how much of it is usable—is the first step.
The home equity calculation is straightforward:
Home Equity = Current Home Value − Total Outstanding Mortgage Balance(s)
For example, if your home is currently worth $400,000 and your remaining mortgage balance is $250,000, your total home equity is $150,000. This represents a 37.5% equity stake in your property.
The loan-to-value ratio is a critical metric that lenders use to assess risk. It is calculated as:
LTV = (Total Mortgage Balance ÷ Home Value) × 100
A lower LTV ratio indicates less risk for the lender. Most financial institutions prefer an LTV of 80% or lower for home equity products. If your LTV exceeds this threshold, you may face higher interest rates or be required to pay private mortgage insurance (PMI).
Not all of your home equity is accessible for borrowing. Usable equity is the amount you can realistically borrow against, calculated as:
Usable Equity = (Home Value × Maximum LTV%) − Total Mortgage Balance
For instance, with a $400,000 home, $250,000 mortgage, and an 80% maximum LTV, your usable equity would be $70,000 ($400,000 × 80% − $250,000). This is the maximum amount most lenders would allow you to borrow through a home equity loan or HELOC.
Both products allow you to access your home equity, but they work differently:
Home equity is a valuable financial resource, but it should be used wisely. Common and recommended uses include home renovations that increase property value, consolidating high-interest debt, funding education expenses, or covering major emergency expenses. It is generally not advisable to use home equity for discretionary spending like vacations or luxury purchases, as your home serves as collateral.
Home equity is the portion of your property that you actually own. It is calculated by subtracting your outstanding mortgage balance from your home's current market value. For example, if your home is worth $400,000 and you owe $250,000 on your mortgage, your equity is $150,000.
Home Equity = Current Home Value − Outstanding Mortgage Balance. This formula gives you the total equity in your property. You can then calculate the loan-to-value (LTV) ratio by dividing your mortgage balance by the home value and multiplying by 100.
A good LTV ratio is typically 80% or lower. Most lenders require LTV below 80% for home equity loans and HELOCs without private mortgage insurance. The lower your LTV, the better your borrowing terms and interest rates.
Yes, you can borrow against your home equity through a home equity loan (lump sum), HELOC (line of credit), or cash-out refinance. Most lenders allow you to borrow up to 80-85% of your home's value minus your mortgage balance.
A home equity loan provides a lump sum with fixed interest rate and fixed monthly payments. A HELOC works like a credit card with a revolving credit line, variable interest rates, and flexible borrowing during the draw period (typically 5-10 years).
For a conventional cash-out refinance, you typically need at least 20% equity (LTV of 80% or less). FHA loans allow up to 85% LTV. VA loans may allow up to 100% LTV. The more equity you have, the better your refinance terms.
Yes, home equity can increase through two main channels: paying down your mortgage balance (which reduces what you owe) and appreciation of your property value (which increases what it is worth). Regular mortgage payments and home improvements both contribute to growing your equity.
When you sell your home, your equity becomes the cash you receive after paying off the remaining mortgage balance and closing costs. For example, selling a $400,000 home with a $200,000 mortgage and $20,000 in closing costs would leave you with $180,000 in cash.
