Home Equity Loan Calculator

A home equity loan is a type of consumer debt that allows homeowners to borrow against the equity in their home. The loan amount is based on the difference between the home's current market value and the homeowner's outstanding mortgage balance. Home equity loans are fixed-rate, lump-sum loans repaid over a set term, typically 5 to 30 years. Because the loan is secured by your home, interest rates are usually lower than unsecured personal loans or credit cards.

Home equity is calculated by subtracting your remaining mortgage balance from your home's current market value. For example, if your home is worth $450,000 and you owe $250,000 on your mortgage, your equity is $200,000. Your equity grows over time as you make mortgage payments (reducing the balance) and as your home appreciates in value.

The loan-to-value ratio is the percentage of your home's value that is financed by loans. It's calculated by dividing your total mortgage debt by the home's appraised value. For home equity loans, lenders use the combined LTV (CLTV), which includes both your primary mortgage and the new equity loan. Most lenders cap CLTV at 80–90%. A lower LTV means less risk for the lender and typically better rates for you.

The maximum you can borrow depends on your lender's maximum CLTV limit, your home's value, and your existing mortgage balance. The formula is: Max Loan = (Home Value × Max LTV%) − Mortgage Balance. For example, with a $450,000 home, $250,000 mortgage, and 85% max LTV, you could borrow up to $132,500.

A home equity loan provides a one-time lump sum at a fixed interest rate with fixed monthly payments. A Home Equity Line of Credit (HELOC) works like a credit card — you get a revolving credit line you can draw from as needed, usually at a variable rate. HELOCs have a draw period (typically 5–10 years) followed by a repayment period. Home equity loans are better for one-time expenses with known costs, while HELOCs offer more flexibility.

A cash-out refinance replaces your entire existing mortgage with a new, larger loan and gives you the difference in cash. A home equity loan is a separate second loan on top of your existing mortgage. If current rates are lower than your existing mortgage rate, a cash-out refinance may be better. If your current rate is already low, a home equity loan lets you keep that rate while borrowing additional funds.

Longer loan terms result in lower monthly payments but significantly more total interest paid over the life of the loan. For example, borrowing $50,000 at 8.5% for 10 years costs about $23,600 in interest, while the same loan over 20 years costs about $52,200 in interest — more than double. Choose the shortest term you can comfortably afford to minimize total cost.

Common fees include origination fees (0.5–1% of the loan), appraisal fees ($300–$600), closing costs, title search fees, legal fees, and recording fees. Some lenders advertise 'no closing cost' loans but may charge a higher interest rate to compensate. Always compare the total cost including fees when shopping for a loan.

The primary risk is that your home serves as collateral. If you default on payments, the lender can foreclose on your property. Other risks include owing more than your home is worth if property values decline (being 'underwater'), increased monthly obligations that may strain your budget, and the temptation to use equity for non-essential expenses. Only borrow what you need and can comfortably repay.

You can reduce costs by: (1) Shopping multiple lenders and comparing APRs, not just interest rates. (2) Choosing the shortest term you can afford. (3) Negotiating or shopping for lower closing costs and fees. (4) Making extra principal payments when possible. (5) Improving your credit score before applying, which qualifies you for lower rates. (6) Borrowing only what you need rather than the maximum available.
