If your home gained value and your mortgage shrank, you are sitting on a low-rate borrowing line most people underestimate. A home equity loan vs HELOC decision comes down to two questions: how much equity can you actually borrow, and do you want one lump sum at a fixed rate or a reusable credit line at a variable rate? The math below answers both.
How much home equity can you borrow?
Equity is simple: market value minus mortgage balance. On a $400,000 home with a $240,000 mortgage, you have $160,000 in equity and a 60% loan-to-value ratio. But lenders will not let you borrow all of it.
The industry standard cap is an 80% combined loan-to-value (CLTV). The formula:
(Home value x 0.80) - mortgage balance = max you can borrow
On our example: ($400,000 x 0.80) - $240,000 = $80,000. Half of your equity is the real borrowing line, not the full $160,000. Run your own numbers in our home equity calculator to see your equity, LTV, and borrowable amount side by side.
Home equity loan vs HELOC: the $60,000 test
Take a $60,000 borrowing need. Here is how the two products compare:
| | Home equity loan | HELOC | |---|---|---| | How you get it | One lump sum | Draw as needed, reuse as you repay | | Rate | Fixed (e.g. 8.5%) | Variable (e.g. 9.5%), can rise | | 15-year fixed payment | $590.84/month | $475/month interest-only during draw period | | Total interest (fixed) | $46,352 | Unknown until rates settle | | Term | 10-30 years | 10-yr draw + 15-yr repayment typical |
The HELOC's interest-only payment looks $115 cheaper per month, but it pays zero principal. When the draw period ends, the same $60,000 starts amortizing at whatever the rate is then. The fixed loan's $590.84 clears the debt in exactly 15 years with a total interest number you can bank on. For how amortization eats your payment the shape is the same: early payments are mostly interest, late ones mostly principal.
Home equity loan vs HELOC: which is better?
Pick the home equity loan when the cost is known and one-time: a $60,000 roof replacement, consolidating card balances, or tuition for one semester. Fixed payment, fixed payoff date, no rate surprise.
Pick the HELOC when costs are spread out or uncertain: a phased kitchen renovation drawn over 9 months, or a business line of credit you only tap when invoices lag. You pay interest only on what you draw, and repaid amounts become available again. The price of that flexibility is a variable rate, so budget for at least a 2-point rate rise.
Neither is a good tool for lifestyle spending. A vacation or a car financed against your house converts optional spending into debt secured by your roof, which is why this decision deserves the same caution as any refinance. If you are rate-shopping your mortgage itself, read should you refinance your mortgage first, because a refi can sometimes beat a second lien.
The real reason people do this: killing card debt
The math that sells equity loans is ugly on the card side. Take $60,000 of credit card debt at 24% APR, paying $800 a month: the balance never clears, because interest outruns the payment. The same $60,000 via a home equity loan at 8.5% for 15 years clears in exactly 180 payments of $590.84, with $5,020.61 in year-one interest versus $14,400 a year on the cards. That is the honest trade: lower rate and a real payoff date in exchange for putting the house behind the debt. Only do it if the cards get closed or frozen, otherwise the debt just grows back on top.

The risk nobody quotes you
Equity is not cash in the bank. If home values fall 10%, our example home is worth $360,000 and the borrowable line drops from $80,000 to $48,000 overnight, and a HELOC lender can freeze or reduce your line during that same downturn. Your payment also jumps if a variable rate climbs. Borrow the amount, not the maximum, and keep a cushion for the worst year, not the average one.
A 60-second decision checklist
- Compute equity and your 80% CLTV cap with the home equity calculator.
- One-time, known cost? Take the fixed-rate home equity loan. Phased, uncertain cost? Take the HELOC.
- Compare year-one interest to your current debt cost before signing.
- Budget the variable rate 2 points higher for the HELOC stress test.
- Close or freeze high-rate cards you pay off, so the debt cannot come back.
FAQ
How much home equity can I borrow?
Lenders cap total borrowing at 80% of your home's value (CLTV). Use (home value x 0.80) - mortgage balance. On a $400,000 home with a $240,000 mortgage, that is $80,000, even though total equity is $160,000. Our home equity calculator computes this for you.
Home equity loan vs HELOC: which is better?
A home equity loan is better for a one-time, known cost because the rate is fixed and the payoff date is certain. A HELOC is better for phased or uncertain costs because you draw only what you need and reuse repaid funds, at a variable rate.
What is the monthly payment on a $60,000 home equity loan?
At 8.5% fixed for 15 years, $60,000 costs $590.84 per month, for $46,352 in total interest. The same draw on a HELOC at 9.5% interest-only is about $475 per month, but that pays no principal.
Can a HELOC rate go up?
Yes. HELOCs are variable-rate products tied to the prime rate, so your payment can rise (or fall) over the life of the line. Stress-test your budget at least 2 points above today's rate before committing.
Is it smart to use home equity to pay off credit cards?
The math usually works: a $60,000 card balance at 24% paying $800 a month never clears, while an 8.5% equity loan at $590.84 a month clears it in 15 years. But it only works if the cards are closed or frozen afterward; otherwise the debt returns on top of the new loan, with the house as collateral.
Can my HELOC be reduced or frozen?
Yes. If your home value drops, your lender can reduce or freeze your HELOC line even if you never missed a payment. In the $400,000 example, a 10% price drop cuts the borrowable line from $80,000 to $48,000.
