When you need to tap into the equity built up in your home, two of the most popular borrowing options are a Home Equity Line of Credit (HELOC) and a Home Equity Loan. Both allow you to borrow against the value of your property, but they work in fundamentally different ways. Choosing the right one can save you thousands of dollars and give you the flexibility — or stability — your project requires.
This guide breaks down how each product works, compares their key features side by side, and helps you determine which option best matches your financial situation and borrowing needs.
What Is a Home Equity Loan?
A home equity loan — sometimes called a "second mortgage" — lets you borrow a fixed amount of money against your home equity in one lump sum. You receive all the funds upfront and repay them over a set period (typically 5 to 30 years) with fixed monthly payments at a fixed interest rate.
This predictability makes home equity loans a strong choice for homeowners who have a clearly defined, one-time expense — such as a full kitchen remodel, a new roof, or consolidating high-interest debt into a single, manageable payment.
How a Home Equity Loan Works: A Calculation Example
Suppose your home is worth $400,000 and you owe $220,000 on your primary mortgage. Your equity is $180,000. Most lenders allow you to borrow up to 80–85% of your home's value, minus what you owe.
($400,000 × 0.85) − $220,000 = $340,000 − $220,000 = $120,000
You could borrow up to $120,000 as a lump-sum home equity loan. If you take $80,000 at a fixed rate of 7.5% over 15 years, your estimated monthly payment would be approximately $741.
What Is a HELOC?
A Home Equity Line of Credit (HELOC) operates more like a credit card than a traditional loan. Instead of receiving a single lump sum, you are approved for a maximum credit limit and can draw from that line as needed during a set "draw period" — typically 5 to 10 years. You only pay interest on the amount you actually borrow, not the full credit limit.
After the draw period ends, you enter the repayment period (often 10 to 20 years), during which you can no longer draw funds and must repay the outstanding balance. HELOC interest rates are almost always variable, meaning they fluctuate with market benchmark rates.
HELOC Calculation Example
Using the same scenario above — home worth $400,000, mortgage balance of $220,000 — you qualify for a HELOC with a credit limit of $120,000. In month one, you draw $30,000 to start a bathroom renovation.
$30,000 × (8.25% ÷ 12) = $30,000 × 0.006875 = $206.25/month
You only pay interest on the $30,000 drawn, not the full $120,000 limit. If you draw more funds next month, your interest payment adjusts accordingly.
Key Differences: HELOC vs Home Equity Loan
- Disbursement: Home Equity Loan = one lump sum upfront | HELOC = revolving credit line, draw as needed
- Interest Rate: Home Equity Loan = fixed rate | HELOC = typically variable rate
- Monthly Payments: Home Equity Loan = fixed, predictable payments | HELOC = interest-only during draw period, varies with balance
- Best For: Home Equity Loan = single large expenses | HELOC = ongoing or unpredictable costs
- Closing Costs: Both typically range from 2–5% of the loan amount
- Risk Level: Both use your home as collateral — missed payments can lead to foreclosure
When to Choose a Home Equity Loan
A home equity loan is the smarter choice when you need a specific, fixed amount of money and prefer the certainty of a set monthly payment. Consider it when you are:
- Paying for a one-time home improvement project with a known total cost
- Consolidating high-interest credit card debt into a single fixed-rate payment
- Making a large purchase (such as a vehicle or education expense) where you need the full amount immediately
- In a rising interest rate environment and want to lock in a fixed rate today
When to Choose a HELOC
A HELOC gives you flexibility that a lump-sum loan cannot match. It is the better option when:
- You are funding a multi-phase renovation project where costs will roll in over months or years
- You want a financial safety net for emergencies without paying interest until you actually draw funds
- Your borrowing needs are uncertain and you don't want to over-borrow (and over-pay interest)
- Interest rates are stable or declining, making the variable rate less risky
Tax Considerations
Interest paid on both HELOCs and home equity loans may be tax-deductible if the borrowed funds are used to "buy, build, or substantially improve" the home that secures the loan, subject to IRS limits on total mortgage debt. However, tax laws change and vary by individual situation. Always consult a qualified tax professional before making decisions based on potential deductibility.
