HELOC vs. home equity loan: what’s the difference?

If you’ve built equity in your home, you have two main ways to borrow against it: a home equity line of credit (HELOC) or a home equity loan. Both let you access cash using your home as collateral, but they work very differently — and choosing the wrong one can cost you significantly. This guide explains how each product works, when each makes sense, and the key risks you need to understand before signing anything.

What is a HELOC?

A home equity line of credit is a revolving credit line — similar to a credit card — secured by your home. Your lender establishes a credit limit based on your equity, and you can borrow, repay, and borrow again during the draw period, which typically lasts 5–10 years.^[1]You only pay interest on what you’ve actually drawn, not the full credit limit.

After the draw period ends, the HELOC enters a repayment period — usually 10–20 years — during which you can no longer borrow and must repay both principal and interest. Most HELOCs carry variable interest rates tied to the prime rate, which means your monthly payment can change whenever the Federal Reserve adjusts rates.

What is a home equity loan?

A home equity loan delivers a lump sum at closing that you repay in fixed monthly installments over a set term — usually 5–30 years.^[2]The interest rate is fixed for the life of the loan, so your payment never changes. Because you receive all the money upfront, interest accrues on the full balance from day one, unlike a HELOC where interest only builds on what you’ve drawn.

Home equity loans are sometimes called a “second mortgage” because they sit behind your primary mortgage in priority — if you default and the home is sold, your first mortgage lender is paid first.

Side-by-side: how they compare

Disbursement: A home equity loan gives you one lump sum; a HELOC gives you a credit line you draw from as needed.

Interest rate: Home equity loans are almost always fixed. HELOCs are almost always variable. Fixed rates provide payment certainty; variable rates expose you to rate fluctuations but often start lower.

Monthly payment: Home equity loan payments are predictable. HELOC payments during the draw period can be interest-only (and small), which can feel manageable — but the repayment period payment can be significantly larger when it kicks in.

Flexibility:HELOCs offer more flexibility because you only borrow what you need, when you need it. If your project costs less than expected, you simply don’t draw the full line.

Closing costs:Both products typically involve closing costs, though some lenders waive them on HELOCs. Compare the total cost carefully — a “no closing cost” offer may include a higher rate instead.

How much can you borrow?

Lenders typically allow you to borrow up to 80%–85% of your home’s appraised value, minus what you still owe on your primary mortgage. This is called the combined loan-to-value (CLTV) ratio.^[5] For example, if your home is worth $400,000 and you owe $250,000, an 80% CLTV limit would give you access to up to $70,000 ($400,000 × 80% = $320,000 − $250,000 = $70,000).

Your credit score, income, and debt-to-income ratio also affect your eligibility and the rate you receive. Borrowers with stronger profiles qualify for larger lines and lower rates. The Federal Reserve’s Survey of Consumer Finances shows that home equity is the largest component of wealth for most middle-class American families, which makes these products both valuable and high-stakes.^[3]

When a HELOC makes more sense

A HELOC is generally the better choice when your borrowing needs are uncertain or spread out over time. Home renovations are a classic example: you might not know the final cost upfront, and contractors are paid in stages. A HELOC lets you draw as invoices arrive rather than paying interest on money you haven’t spent yet.

HELOCs also work well as a financial safety net if you have a stable income but want access to emergency funds without a formal loan application. You pay nothing unless you draw.

The main risk is rate volatility. If prime rate rises sharply — as it did in 2022–2023 — your HELOC payment rises with it. Make sure your budget can absorb a higher payment before you rely on a variable-rate line.

When a home equity loan makes more sense

A home equity loan is the better choice when you know exactly how much you need and want payment certainty. Debt consolidation is a prime use case: you replace multiple variable-rate credit card balances with a single fixed monthly payment at a lower rate. Home equity loan rates are generally far lower than credit card APRs, making the math compelling if you’re disciplined enough not to run the cards back up.

They also suit large, one-time expenses — a significant medical bill, a vehicle purchase, or tuition — where the total cost is known in advance and you prefer the simplicity of a single installment loan.

Tax deductibility

Interest on both HELOCs and home equity loans may be tax-deductible, but only if the proceeds are used to “buy, build, or substantially improve” the home securing the debt.^[4] Interest on funds used for debt consolidation, vacations, or other personal expenses is generally not deductible under current law. Consult a tax professional for guidance on your specific situation.

The key risk: your home is collateral

Both products use your home as collateral. If you miss payments, the lender can foreclose — even if you’re current on your primary mortgage. This is the most important distinction from unsecured debt like credit cards or personal loans. Never borrow more than you can comfortably repay, and never use home equity to finance purchases that depreciate in value (like vehicles or consumer electronics) if a less-risky option exists.

How to calculate your costs

Before applying for either product, model the numbers. For a home equity loan, use a loan payment calculator to see your fixed monthly payment and total interest over the term. For a HELOC, use the HELOC calculator to model draw scenarios and estimate how a rate increase would affect your payment. Run both calculators with the same loan amount and compare total interest paid — the difference is often smaller than people expect, especially when you factor in the flexibility value of the HELOC.

Which should you choose?

Choose a HELOC if you need flexible, ongoing access to funds over time, can tolerate a variable rate, and want to pay interest only on what you use.

Choose a home equity loan if you know your exact borrowing need, want a fixed monthly payment, and prefer the simplicity of a single installment loan.

In both cases, shop at least three lenders. Rates, fees, and CLTV limits vary enough that comparison shopping can meaningfully change the cost of borrowing.
