Both a home equity line of credit and a home equity loan let you borrow against the equity built up in your house, using the home as collateral, and both typically offer lower interest rates than unsecured borrowing since the lender's risk is reduced by that collateral. Where they differ is structure: a home equity loan hands you a fixed lump sum with a fixed rate and a set repayment schedule, while a HELOC works more like a credit card, giving you a credit line to draw from as needed at a variable rate.
How Much You Can Typically Borrow
Lenders generally allow borrowing up to a combined loan-to-value ratio of 80 to 85 percent across your primary mortgage and the new equity borrowing combined. If your home is worth $400,000 and you owe $220,000 on the mortgage, an 80 percent combined limit would allow roughly $100,000 in additional equity borrowing, though the actual amount offered depends on credit score, income, and the specific lender's policies.
A Home Equity Loan Fits a Known, One-Time Cost
Because the amount, rate, and monthly payment are fixed at closing, a home equity loan is the better fit for a single, defined expense — a major renovation with a set contractor bid, consolidating a specific amount of higher-interest debt, or a one-time large purchase. The fixed payment makes it straightforward to build into a budget from day one, similar to any other installment loan, and it removes the risk of a rising rate increasing the payment later the way a variable-rate product could.
A HELOC Fits an Ongoing or Uncertain Need
A HELOC is structured in two phases: a draw period, often 10 years, during which you can borrow, repay, and borrow again up to the credit limit, paying interest only on what is actually drawn, followed by a repayment period where the credit line closes and the outstanding balance amortizes over a fixed term, commonly 10 to 20 years. This makes a HELOC a better fit for costs that unfold over time or are not fully known upfront — a renovation done in phases, ongoing home repairs, or a financial cushion you would rather not carry as debt unless actually needed, similar to the flexibility described in building a home repair and maintenance fund, just funded through borrowed equity rather than cash savings.
The Variable Rate Risk on a HELOC
Because HELOC rates are usually tied to a benchmark rate that moves with broader interest rate changes, the payment on an outstanding balance can rise without warning, unlike the fixed payment on a home equity loan. This risk is smaller during the draw period if you are keeping balances low or paying them off between draws, but it becomes more significant once the repayment period begins and a larger balance starts amortizing at whatever the variable rate happens to be at that point. Some lenders allow converting part or all of a HELOC balance to a fixed rate during the draw period, which is worth asking about if rate stability matters more to your situation than the flexibility of a variable rate.
Closing Costs and Fees
Both products can carry closing costs similar to a mortgage refinance — appraisal fees, title work, origination charges — though many lenders waive some or all of these on smaller HELOCs to stay competitive, sometimes with a clause requiring repayment of waived fees if the line is closed within a short period, commonly two to three years. Comparing the full fee schedule, not just the advertised rate, between a few lenders is worth the time given how much these costs vary by lender for what is otherwise a similar product.
The Tax Deduction Question
Interest on either a home equity loan or a HELOC is generally only tax-deductible if the funds are used to buy, build, or substantially improve the home securing the loan, not for unrelated expenses like debt consolidation or education costs, following rules that changed with a major tax law update in the last decade. This detail is easy to misremember from older, more permissive rules, so checking current guidance rather than assuming the interest is automatically deductible is worth doing before counting on it in your calculations. The IRS guidance on home equity loan interest deductibility lays out the specific requirements.
Choosing between the two comes down to how well-defined the expense is: a known, one-time cost fits a home equity loan's fixed structure, while an ongoing or uncertain need fits a HELOC's draw-as-needed flexibility, with the tradeoff being rate stability versus rate flexibility in each case.
