A home equity line of credit (HELOC) is a revolving line of credit secured by the equity in your home. It works similarly to a credit card: you are approved for a maximum credit limit, you draw from it as needed, and you pay back what you use plus interest. The key difference is that your home serves as collateral.
HELOCs are one of the cheapest ways to borrow money for large expenses, but they carry real risk. This guide explains how they work, what they cost, when they make sense, and what to watch out for.
How Does a HELOC Work?
A HELOC has two phases: the draw period and the repayment period.
Draw period (typically 10 years): During this phase, you can borrow against your credit limit as needed. Most lenders require interest-only payments during the draw period, though you can pay down principal if you want. The credit line is revolving — as you pay back what you borrow, you can borrow it again.
Repayment period (typically 10 to 20 years): Once the draw period ends, the line closes and you begin repaying the outstanding balance in full — principal plus interest. Payments increase significantly during repayment because you are now paying down principal instead of just interest.
How Much Can You Borrow?
Lenders generally allow you to borrow up to 80% to 85% of your home’s value, minus what you still owe on your mortgage. This is called your combined loan-to-value (CLTV) ratio.
Example: If your home is worth $400,000 and you owe $200,000 on your mortgage, your equity is $200,000. At an 80% CLTV limit, you could access up to $120,000 via a HELOC ($400,000 x 80% = $320,000, minus the $200,000 mortgage balance).
HELOC Interest Rates in 2026
Most HELOCs carry variable interest rates tied to the prime rate. In 2026, HELOC rates typically range from 7% to 10% depending on your credit score, the lender, and the loan-to-value ratio.
Some lenders offer fixed-rate HELOCs or allow you to lock in a fixed rate on a portion of your balance. If you plan to carry a large balance for an extended period, ask your lender about rate-lock options.
What Are HELOCs Used For?
Common uses include:
- Home improvements and renovations: The most common use. Using a HELOC to fund renovations can increase your home’s value and the interest may be tax-deductible (consult a tax advisor).
- Debt consolidation: Consolidating high-interest credit card debt at a HELOC rate of 8% vs. a credit card rate of 25% can save thousands in interest — but only works if you do not run the credit cards back up.
- Emergency fund backup: Some homeowners establish a HELOC as a backup emergency fund, drawing on it only if their cash reserves run out.
HELOC vs. Home Equity Loan: What’s the Difference?
A home equity loan gives you a lump sum at a fixed interest rate, repaid over a set term. A HELOC is a revolving credit line at a variable rate. Choose a home equity loan when you need a specific amount for a defined project and want payment certainty. Choose a HELOC when you want flexible access to credit over time.
Pros and Cons of a HELOC
Pros:
- Lower interest rates than credit cards and personal loans
- Flexible borrowing — draw what you need, when you need it
- Interest may be tax-deductible for home improvements (consult a tax advisor)
- No interest charges until you draw from the line
Cons:
- Your home is collateral — if you default, you can lose it
- Variable rates mean your payment can increase if rates rise
- Payment shock when the repayment period begins if you only paid interest during the draw period
- Reduces your home equity and financial cushion
How to Qualify for a HELOC
Lenders typically require:
- At least 15% to 20% equity in your home
- Credit score of 680 or higher (better rates at 740+)
- Debt-to-income ratio below 43%
- Stable income and employment history
The application process is similar to a mortgage refinance: you will provide proof of income, tax returns, and bank statements, and the lender will order an appraisal to confirm your home’s value.
Is a HELOC Right for You?
A HELOC makes sense if you have substantial home equity, a strong credit score, a specific need for flexible credit, and the discipline not to treat it as spending money. It makes less sense if your income is variable, if you are close to retirement, or if you are consolidating credit card debt only to run the cards back up.
Before opening a HELOC, compare rates from at least three lenders. Local credit unions often offer competitive rates with lower fees than large banks. Ask about origination fees, annual fees, early termination fees, and minimum draw requirements.
Bottom Line
A HELOC is one of the lowest-cost borrowing options available to homeowners, but it is not free money. You are pledging your home as collateral and taking on variable-rate debt that can increase over time. Used thoughtfully for home improvements or genuine financial needs, a HELOC can save you tens of thousands in interest compared to alternatives. Used carelessly, it puts your home at risk.
