Both a HELOC and a home equity loan let you borrow against the value you've built in your home, and both are secured by the property itself. Both are also considered "second liens" — they sit behind your primary mortgage, so if you ever sell or foreclose, the first mortgage gets paid before either of these. But day to day they behave very differently: one works like a credit card, the other like a second mortgage with a fixed payment. Choosing the wrong one can cost you thousands in interest or leave you exposed to rising rates. Here's how they actually compare, with a worked example and answers to the questions homeowners ask most.
A HELOC (Home Equity Line of Credit) is a revolving credit line. You're approved for a maximum amount — say $75,000 — then during a draw period (typically 10 years) you borrow only what you need, when you need it, and pay interest only on the outstanding balance. Borrow $10,000 and you pay interest on $10,000, not the full line. After the draw period ends, you enter a repayment period (often 20 years) where the line closes to new draws and you pay down principal plus interest, which usually raises your monthly payment.
Most HELOCs carry a variable interest rate tied to the prime rate plus a margin, so your payment can rise or fall as the Federal Reserve moves rates. Some lenders let you convert a portion of the balance to a fixed rate. HELOCs also often allow interest-only payments during the draw period, which keeps early payments low but means you're not reducing the balance — a trap worth understanding before you sign.
A home equity loan gives you the full amount as a single lump sum upfront, at a fixed interest rate, repaid over a set term (commonly 5 to 30 years) with equal monthly payments. Because the rate and payment never change, it's sometimes called a "second mortgage." You know exactly what you'll pay every month for the life of the loan, which makes budgeting simple. The trade-off: you start paying interest on the entire balance from day one, whether or not you've spent all the money yet. The Consumer Financial Protection Bureau frames the split the same way: with a home equity loan "you receive the money you are borrowing in a lump sum payment," while a HELOC lets you "borrow or draw money multiple times from an available maximum amount" — see the CFPB's side-by-side explainer.
| Feature | HELOC | Home equity loan |
|---|---|---|
| How you get funds | Draw as needed | Lump sum upfront |
| Interest rate | Usually variable | Fixed |
| Payment | Can change over time | Predictable, fixed |
| Best for | Ongoing or uncertain costs | One-time known expense |
| Interest charged on | Only what you borrow | The full balance |
| Payment structure | Interest-only draw, then P&I | Fixed principal & interest |
Suppose you need to fund a $40,000 kitchen remodel and you're comparing a home equity loan at a fixed 8.2% over 10 years against a HELOC at a variable 8.5%.
The lesson: if you'll spend the full $40,000 right away and want certainty, the fixed loan is often the cleaner choice. If the spending is staggered or uncertain, the HELOC can save interest early — as long as you can absorb a higher payment later. Plug your own figures into the home equity calculator to see the total cost of each side by side.
A HELOC tends to win when your expenses are spread out or uncertain — a multi-phase renovation, tuition paid semester by semester, or a rainy-day reserve you may never fully tap. You avoid paying interest on money sitting unused. A home equity loan wins when you have a single, known cost — a $40,000 kitchen remodel or a debt consolidation — and you want the certainty of a fixed payment that won't move if rates climb.
Rate environment matters too. When rates are expected to fall, a variable HELOC can get cheaper over time. When rates are rising or volatile, the fixed payment of a home equity loan protects your budget. Your own discipline matters as well: a HELOC's easy access to cash can tempt overspending, while a lump-sum loan forces you to commit to one amount up front.
Both products often carry closing costs and appraisal fees. HELOCs can add more: the CFPB notes a lender may charge an application fee, an annual or membership fee, an inactivity fee "for not using your HELOC," an early-termination fee (usually if you close within the first two or three years), and even a conversion fee to lock part of the balance to a fixed rate — the full list is on the CFPB's HELOC fees page. More importantly, both use your home as collateral. If you can't repay, you risk foreclosure — a risk that simply doesn't exist with an unsecured credit card or personal loan. One protection worth knowing: because these loans are secured by your primary residence, federal law gives you a right of rescission — three business days after closing to cancel for any reason — as the CFPB explains in its right-of-rescission guidance.
When you're stuck between the two, run through four questions in order. First, is the amount you need fixed and known, or uncertain and spread out? A fixed remodel bid points to the loan; an open-ended series of expenses points to the line. Second, how sensitive is your budget to a payment increase? If a rising rate would strain you, the fixed loan removes that risk entirely. Third, where are rates headed? Nobody can time this perfectly, but if you have a strong view that rates will fall, a variable HELOC can capture that; if you'd rather not gamble, lock a fixed loan. Fourth, how disciplined are you with revolving credit? A HELOC's tap-anytime access is a feature for some borrowers and a temptation for others.
Also weigh the total cost of ownership, not just the headline rate. Ask each lender about closing costs, appraisal fees, annual fees, early-closure fees, and whether a HELOC lets you convert part of the balance to a fixed rate. Two offers with the same advertised rate can differ by hundreds of dollars a year once fees are included. Getting written quotes from more than one lender — and comparing them against the totals from the home equity calculator — is the surest way to see which product is genuinely cheaper for your situation rather than which one simply feels cheaper up front.

Can I have both a HELOC and a home equity loan at the same time? Yes, in principle — but only up to your lender's combined loan-to-value (CLTV) limit, which counts every loan secured by the home. Most lenders cap total borrowing around 80–85% of your home's value, so having one product reduces how much you can access with another.
Is the interest tax-deductible? It can be, but only in specific cases. Under current federal rules, interest on home equity borrowing is generally deductible only when the funds are used to "buy, build, or substantially improve" the home securing the loan, and it counts toward the overall mortgage-interest cap (generally the first $750,000 of home-secured debt, or $375,000 if married filing separately). The details are in IRS Publication 936. This is tax-dependent and changes over time, so confirm your situation with a tax professional — nothing here is tax advice.
Which one is easier to qualify for? Requirements are similar — lenders look at your credit score, income, debt-to-income ratio, and CLTV. HELOCs sometimes have slightly more flexible minimums, but a strong credit profile helps with both. Only a licensed lender can tell you what you'll actually qualify for.
