Monthly Payment on a $50,000 Home Equity Loan at 8.5% Interest

How Home Equity Loan Payments Are Calculated

Home equity loans use the same fixed-payment amortization formula as your first mortgage — a level monthly payment split between interest and principal so the balance reaches exactly zero on the final scheduled payment. Early payments are weighted more toward interest; later payments are weighted more toward principal, exactly as with any amortizing loan.

• M — monthly payment
• P — loan amount (equity borrowed)
• r — monthly interest rate (annual rate ÷ 12)
• n — total number of monthly payments

Loan-to-Value (LTV) and How Much You Can Borrow

Lenders cap how much you can borrow using your combined loan-to-value ratio — your existing mortgage balance plus the new loan, divided by your home's value. Most lenders cap this at 80%, though some go as low as 70% or as high as 90%. The formula is: home value × max LTV − existing mortgage balance = maximum equity you can borrow. For example, on a $500,000 home with an 80% LTV cap and a $230,000 existing mortgage balance: $500,000 × 80% − $230,000 = $170,000 available to borrow. Most lenders also apply an absolute dollar cap on top of the LTV formula, commonly around $1 million.

Qualification and Costs

Beyond LTV, lenders look at credit score (borrowers below roughly 630 may not qualify), debt-to-income ratio (a DTI above about 43-50% often disqualifies an applicant), property condition, and any existing liens. Upfront closing costs — origination, appraisal, document, and title search fees — typically run 2% to 5% of the loan amount and can be paid at closing or rolled into the loan balance. Some lenders offer no-closing-cost loans, but these usually carry a higher interest rate and may limit or penalize early payoff, so compare the APR (which bakes closing costs into an annualized rate) rather than the interest rate alone when shopping lenders.

Home Equity Loan vs. HELOC vs. Cash-Out Refinance

A home equity loan gives you a lump sum up front at a fixed rate — best when you know exactly how much you need, such as a specific renovation or debt consolidation payoff. A HELOC (home equity line of credit) instead gives you a draw period where you borrow only what you need, when you need it — better suited to ongoing or uncertain costs like tuition paid over several years, but it usually carries a variable rate, adding uncertainty to your payment. A cash-out refinance replaces your entire first mortgage with a larger one and gives you the difference in cash — worth considering instead of a second loan when current market rates are lower than your existing mortgage rate, and it may offer better mortgage interest tax deductibility than a separate home equity loan.

About These Parameters

Home's Current Value

Your home's current market value, not its purchase price — lenders typically require a fresh appraisal, but a recent comparable sale in your area gives a reasonable estimate for planning purposes.

Existing Mortgage Balance

The remaining balance on your primary mortgage (and any other liens against the home). This directly reduces how much equity is available to borrow against.

Max Loan-to-Value Allowed

The maximum combined LTV your lender permits. 80% is the most common cap, though some lenders allow up to 90% for well-qualified borrowers, or cap it lower at 70% for riskier profiles.

Loan Amount Requested

How much you actually want to borrow, up to the available equity calculated from the fields above. Lenders will typically counter-offer a lower amount if your request exceeds their LTV cap.

Loan Term

Home equity loans commonly run 5 to 30 years. A shorter term means a higher monthly payment but far less total interest; a longer term lowers the payment but substantially increases the total cost of borrowing.

Closing Costs

Origination, appraisal, document, and title fees, typically 2% to 5% of the loan amount. These can usually be paid up front or rolled into the loan balance.
