Equity

Definition

Equity is ownership value. It's calculated by taking what an asset is worth and subtracting any debt attached to it. For a house, it's the market value minus your principal balance. For a car, it's the resale value minus your loan balance. Building equity over time is how assets move from being liabilities to being assets. Equity represents wealth you've built.

Why it matters

Equity is your financial cushion. As you pay down a mortgage through amortization, your equity grows and you own more of your home. Home equity can be borrowed against for major expenses (via a home equity line of credit), unlike renting where you build nothing. Rapidly falling property values destroy equity fast (as happened in 2008), while steady payment and property appreciation both build it. Many people don't realize they have significant equity until they try to sell or refinance.

Quick example

You buy a house for $400,000 with a $400,000 mortgage. You have zero equity. You pay down the mortgage to $320,000 while the house appreciates to $450,000. Your equity is now $450,000 minus $320,000, which equals $130,000. You could borrow against that equity or sell and pocket the difference.

The bottom line

Knowing what Equity means helps you make better day-to-day money decisions. It makes rates, account options, and tradeoffs easier to compare.
