Home Equity

Home equity is the portion of your home's value that you actually own — the market value minus any outstanding mortgage balance. Equity grows as you pay down principal and as the home appreciates.

Formula
Home equity = Current market value − Outstanding mortgage balance
Example

Home worth $550,000 with $310,000 remaining on mortgage → equity = $240,000 (43.6% LTV equity).

Home equity is built two ways: by making mortgage payments (which reduce the loan balance) and through home price appreciation. A homeowner who bought a $400,000 home with a $320,000 mortgage and now owes $280,000 while the home is worth $450,000 has $170,000 in equity.

You can borrow against home equity through a home equity loan (lump sum, fixed rate) or a HELOC (home equity line of credit, variable rate). Both use your home as collateral — defaulting risks foreclosure.

Equity is the primary source of housing wealth for most American families and can fund major expenses (renovations, education, retirement). However, it is illiquid — you cannot spend equity without selling the home or taking on new debt.

Refinancing
Refinancing replaces an existing loan with a new one, typically at a lower interest rate, different term, or both. The goal is usually to reduce monthly payments or total interest paid.
