A homeowner with $200,000 in equity takes out a $100,000 home equity loan at 8.5% fixed. Interest starts accruing on the full $100,000 immediately, costing $708/month in principal and interest on a 20-year term. That same homeowner could open a $100,000 HELOC, draw $30,000 for a kitchen remodel, and pay interest only on the $30,000 until they need more. At 8.75% variable, the interest-only payment on $30,000 is $219/month. The remaining $70,000 sits available at zero cost until drawn.
If you know exactly how much you need and you need it all at once, a home equity loan locks in a fixed rate and a fixed payment. If there's any chance you'll use less than the full amount or need the money in stages, the HELOC saves you interest on every dollar you don't touch.
How They Actually Work
Both products let you borrow against your home's equity. Most lenders allow a combined loan-to-value (CLTV) of 80-90%, meaning your first mortgage balance plus the new borrowing can't exceed 80-90% of your home's value. On a home worth $600,000 with a $350,000 mortgage, you could access $130,000-$190,000 depending on the lender's CLTV cap.
A home equity loan delivers the full amount at closing. You get a fixed rate, fixed term (typically 5-20 years), and fixed monthly payment. Closing costs run 2-5% of the loan amount. It works like a second mortgage with a predictable payoff schedule.
A HELOC works like a credit card secured by your home. The lender approves a credit limit, and you draw against it as needed during a 10-year draw period. During that time, most HELOCs require interest-only payments on whatever you've borrowed. After the draw period ends, you enter a 10-20 year repayment period where you pay principal and interest on the remaining balance. Closing costs are typically minimal, often under $500.
The rate structure is the fundamental difference. Home equity loans are fixed. HELOCs are variable, usually tied to the prime rate plus a margin. When the Fed cuts rates, HELOC payments drop. When rates rise, payments increase. Some lenders now offer fixed-rate HELOC options that let you lock portions of your balance at a fixed rate while keeping the rest variable.
The Cost Comparison That Matters
The rate on a HELOC is usually 0.25-0.50% higher than a comparable home equity loan. Borrowers see that and assume the home equity loan is cheaper. It's not, unless you use every dollar.
| Scenario | Home Equity Loan (8.5% fixed) | HELOC (8.75% variable) |
|---|---|---|
| Borrow $100K, use $100K | $708/mo, $69,920 total interest | ~$730/mo, varies with rates |
| Borrow $100K, use $50K | $708/mo on full $100K | ~$365/mo on $50K drawn |
| Borrow $100K, use $30K first year, $70K later | $708/mo from day one | ~$219/mo year one, scales up |
The HELOC wins whenever you don't need the full amount immediately. A homeowner renovating in phases, covering college tuition over four years, or keeping a credit line open for emergencies pays dramatically less in interest with a HELOC because they're only charged on what they've actually used.
The home equity loan wins in one scenario: you need the full amount, you want payment certainty, and you believe rates are heading higher. Locking 8.5% fixed on $100,000 when you expect prime to climb another 1-2% protects you from payment increases. But that bet has to be right to justify paying interest on money you might not otherwise need.
Payment Shock on HELOCs
The risk that catches HELOC borrowers off guard is the transition from draw period to repayment period. During the 10-year draw period, you're making interest-only payments. When repayment begins, the payment jumps to include principal amortization over the remaining term.
On a $80,000 HELOC balance at 8.75% with a 15-year repayment period, the interest-only payment during the draw period is $583/month. When repayment kicks in, it jumps to $797/month. That's a 37% increase. Borrowers who stretched to afford the interest-only payment can find themselves in trouble.
The solution is straightforward: make principal payments during the draw period even though they're not required. Treating the HELOC like a regular loan from the start eliminates the payment shock and builds equity faster. Most borrowers don't do this because the interest-only minimum feels easier, which is exactly why the repayment transition creates problems.
Qualification and Costs
Both products have similar qualification requirements: 620+ credit score (740+ for the best rates), DTI under 43%, and a home appraisal to confirm current value. The key differences are in the fees.
Home equity loans carry closing costs similar to a mortgage refinance. On a $100,000 loan, expect $2,000-$5,000 in appraisal fees, title insurance, origination fees, and recording costs. These can be financed into the loan, but that increases the balance you're paying interest on.
HELOCs typically have much lower upfront costs. Many lenders waive closing costs entirely on HELOCs above $25,000, especially during promotional periods. The trade-off is that some HELOCs carry annual fees ($50-$100) and inactivity fees if you don't draw on the line within a certain period.
Tax Deductibility
Interest on both products is tax-deductible only if the funds are used to buy, build, or substantially improve the home that secures the loan. A kitchen renovation qualifies. Paying off credit card debt does not. This changed with the Tax Cuts and Jobs Act of 2017, and borrowers who plan to deduct the interest should keep detailed records of how the funds were used. Consult a tax professional for your specific situation.
Which One to Choose
For a single large expense with a defined cost, like a $60,000 roof replacement or a $40,000 debt consolidation, the home equity loan's fixed payment and fixed rate make sense. You know what you owe, you know what you pay, and you know when it's done.
For everything else, the HELOC is more efficient. Home improvements done in stages, tuition payments spread over years, or simply having access to capital without paying for it until you need it. The flexibility of drawing only what you need, when you need it, saves interest in virtually every scenario where the full amount isn't required on day one.
