Home equity, explained
If you own a home, “equity” is one of the most useful numbers to understand — and one of the easiest to estimate.
What home equity is
Home equity is simply the part of your home you own outright. In plain terms, it’s your home’s current market value minus everything you still owe against it. If your home is worth $400,000 and your remaining mortgage balance is $250,000, your equity is roughly $150,000.
That number isn’t fixed. It rises as you pay down your mortgage and, separately, as your home’s market value changes over time.
How equity builds
Equity grows in two main ways. The first is paying down principal: every mortgage payment chips away at what you owe, and over the years that adds up. The second is appreciation: when local home values rise, your equity can grow even if your loan balance hasn’t changed. Of course, values can also fall, which works in the other direction.
How much you may be able to access
Owning equity isn’t the same as being able to borrow all of it. Lenders typically let homeowners borrow against a portion of their home’s value — commonly up to around 80–85% — minus the balance still owed on the mortgage. This is sometimes called the combined loan-to-value, or CLTV.
A simplified example: on a $400,000 home with a $250,000 balance, a lender allowing 85% CLTV would calculate roughly $340,000 (85% of value) minus $250,000 owed, leaving about $90,000 of potentially accessible equity. The exact figure depends on the lender, your credit, your income, and the product. This is an illustration, not a quote.
Common ways homeowners tap equity
Two of the most common tools are a home equity line of credit (HELOC), which works a bit like a credit line you can draw from as needed, and a cash-out refinance, which replaces your existing mortgage with a larger one and returns the difference in cash. Each has trade-offs around rates, payments, and structure, and the right fit depends entirely on your situation.
The bottom line
Estimating your equity takes a minute and costs nothing. Whether tapping it makes sense is a personal decision that depends on your goals, your budget, and the specific terms a lender offers. Reviewing your options is free and carries no obligation.
