If you have owned your home for a few years, you are probably sitting on a valuable asset beyond the house itself: equity, the difference between what your home is worth and what you still owe on the mortgage. Two popular products let you borrow against that equity — a home equity loan and a home equity line of credit, or HELOC. They sound almost identical, but they work in very different ways, and picking the wrong one can cost you thousands. Here is how to choose.

The Basic Difference

A home equity loan is a lump sum. You borrow a fixed amount, receive it all at once, and repay it over a set term — often 5 to 30 years — at a usually fixed interest rate. It is effectively a second mortgage with its own monthly payment alongside your main one.

A HELOC is a revolving credit line secured by your home, more like a credit card with a much bigger limit and a much lower rate. During the draw period, typically 10 years, you can borrow, repay and borrow again up to your limit, often paying interest only on what you have drawn. After that comes the repayment period, often 20 years, when you repay principal and interest and can no longer draw.

Interest Rates and Payments

Predictability is the home equity loan’s biggest strength: the rate is fixed, so your payment never changes, which makes long-term budgeting simple. HELOC rates are usually variable, tied to the prime rate, so your payment can climb when central bank rates rise — sometimes sharply. HELOCs often start with a lower rate than home equity loans, and interest-only payments during the draw period keep early costs low. The catch arrives when the draw period ends: payments jump because you start repaying principal over a shorter window, a shock many borrowers fail to plan for. Some HELOCs let you lock portions of your balance at a fixed rate; ask if that option exists.

Costs and Fees to Compare

Both products can carry closing costs, typically 2 to 5 per cent of the loan amount for a home equity loan, covering appraisal, origination and legal fees. HELOCs sometimes have lower upfront costs but may add annual fees, draw fees or early-closure charges if you shut the line within the first few years. Lenders also differ on how much equity you need: most want you to keep at least 15 to 20 per cent equity in the home after borrowing, and rates improve with a credit score above 700. As with any loan, compare the APR and total fees from at least three lenders.

When a Home Equity Loan Fits Better

• You have one large, clearly priced expense — a roof, a kitchen remodel with a firm quote, or consolidating high-interest debts into one fixed payment.
• You want the certainty of a payment that never changes.
• You prefer the discipline of a fixed schedule that steadily reduces the balance.

When a HELOC Fits Better

• Your costs are spread out or uncertain — a renovation in stages, tuition bills over several years, or a safety net for irregular income.
• You only want to pay interest on money you actually use.
• You are disciplined enough not to treat the line as free money, and you can handle payments rising if rates go up.

The Risk Both Share

Whichever you choose, the loan is secured by your home. Miss payments and you could face foreclosure — a risk no unsecured loan carries. That is why financial planners warn against using either product for holidays, cars or everyday spending. Both work best when the borrowing itself improves your position: a renovation that adds value, an education that raises earnings, or wiping out far more expensive credit card debt with a firm plan not to run the cards up again. One more detail for US borrowers: interest is generally tax-deductible only when the money is used to buy, build or substantially improve the home securing the loan.

Conclusion

Choose a home equity loan for a single, known expense and the calm of a fixed payment. Choose a HELOC for flexible, staged borrowing where you may not need the full amount at once. Either way, borrow the minimum you need, keep a buffer of equity in your home, and have a repayment plan before you sign. Your equity took years to build; spend it on things that build value back.

A Quick Worked Example

Say your home is worth $450,000 and you owe $270,000 on the mortgage, giving you $180,000 of equity. A lender that wants you to keep 20 per cent equity — $90,000 — could let you borrow up to $90,000. Take it as a home equity loan and you repay $90,000 over, say, 15 years at a fixed rate, paying interest on the whole sum from day one but with a payment that never changes. Take it as a HELOC and you might draw $40,000 this year for a kitchen, repay much of it down, then draw again for a bathroom — paying interest only on what is outstanding at the time. The right structure depends entirely on how your spending actually unfolds, so map the project first and let the costs choose the product.
