A home is often a family's most valuable financial asset. As you pay down your mortgage and property values appreciate, you build "equity"—the portion of the property you truly own outright. Financial institutions allow you to borrow against this equity through a Home Equity Loan (a lump sum with a fixed rate) or a Home Equity Line of Credit (HELOC, a revolving credit line with a variable rate). Accurately calculating your usable equity is the first step in unlocking capital for renovations, debt consolidation, or emergency expenses.

Usable Equity Formula

Total Equity = Appraised Home Value - Current Mortgage Balance
Usable Equity = (Home Value × Max LTV %) - Current Mortgage Balance
Lenders typically cap the Loan-to-Value (LTV) ratio at 80% to 85%.

Frequently Asked Questions (FAQ)

What is the main difference between a Home Equity Loan and a HELOC?

A Home Equity Loan provides a one-time lump sum of cash with a fixed interest rate and fixed monthly payments. A HELOC acts like a credit card tied to your home's value; you can draw money as needed, repay it, and draw again, but the interest rate is variable and fluctuates with the market.

Is the interest on a HELOC tax-deductible?

In the United States, the interest paid on home equity loans and HELOCs is only tax-deductible if the borrowed funds are used to "buy, build, or substantially improve" the home that secures the loan. If you use the funds to pay off credit card debt or buy a car, the interest is not deductible.
