How a HELOC Works
A home equity line of credit, often called a HELOC, is an open-end loan secured by your home. The lender approves a maximum credit limit and you can draw money as needed during the draw period, up to that limit. Unlike a closed-end home equity loan that pays a lump sum, a HELOC works more like a credit card tied to your home: you can borrow, repay, and borrow again while the draw period is open.
The amount you can borrow generally depends on your home equity, which is the difference between your home's market value and the balances of mortgages or other liens against it. Lenders also review credit history, income, debts, and the combined loan-to-value ratio. Because the home secures the line, the lender can foreclose if you fail to repay according to the agreement.
The Consumer Financial Protection Bureau home buying resources explain that a HELOC is a mortgage product, not a personal loan, and that borrowers receive important disclosures before closing. For a side-by-side look at alternatives, see HELOC vs. home equity loan.
Draw Period and Repayment Period
Most HELOCs split the loan into two phases: a draw period and a repayment period. During the draw period, you can access available credit. Some lenders require interest-only payments on the amount you have drawn; others may require principal and interest. A HELOC may also have a minimum payment if you have no balance, or no payment until you draw.
When the draw period ends, the line typically enters repayment. You can no longer draw, and payments usually include both principal and interest over a set term. The shift can raise your monthly payment because principal is now included. If the HELOC has a balloon feature, the entire remaining balance may be due at the end, so reviewing the agreement is essential.
Under the Truth in Lending Act, the lender must disclose the APR and other terms before you sign. The CFPB Truth in Lending regulation covers open-end credit disclosures, including HELOCs. Ask the lender to explain what happens at the end of the draw period before you commit.
How HELOC Interest and Payments Work
HELOC interest rates are often variable, meaning the rate can change based on an index plus a margin set by the lender. When the index rises or falls, your rate and payment can change. Some HELOCs let you convert part of the balance to a fixed-rate option, but that feature may have conditions or fees.
Because the line is open-end credit, interest may accrue on the daily balance. The lender calculates payments based on your outstanding balance, your rate, and the terms in your agreement. A small increase in the rate can affect the payment if you carry a large balance.
Interest on home equity debt may be tax deductible in some situations, but the rules are specific. The IRS Topic No. 505 explains that deductibility depends on how the funds are used and other tax rules. This guide does not provide tax advice; consult a qualified tax professional about your situation.
What a HELOC Costs
HELOC costs can include an application fee, appraisal fee, title search, recording fees, and closing costs. Some lenders waive certain fees but may charge an annual fee, a transaction fee for each draw, or an early closure fee if you pay off and close the line within a stated period. Those fees should be listed in your loan estimate and closing disclosure.
A HELOC may also have a promotional or introductory rate. Read the fine print to see when it ends and how the rate adjusts afterward. The FTC credit and loans guidance advises comparing the annual percentage rate, fees, and repayment terms rather than focusing on a single low introductory rate.
Use our home equity loan calculator to estimate how different rates and terms could affect payments, but remember that a calculator is an educational tool, not a loan offer. Compare several offers and ask each lender for a full cost breakdown.
How to Qualify for a HELOC
Qualification usually depends on equity, credit, income, and debt. Lenders typically require you to have a certain amount of equity after accounting for all mortgage liens. They also review your credit score, payment history, employment, and debt-to-income ratio. A higher combined loan-to-value ratio or a lower credit score may lead to a smaller line or a higher rate.
You will usually need to provide proof of income, recent tax returns, bank statements, and information about your mortgage and other debts. The lender may order an appraisal or use an automated valuation. If you are self-employed or have irregular income, you may need additional documentation.

HELOC vs. Home Equity Loan vs. Cash-Out Refinance
Three common ways to borrow against home equity are a HELOC, a home equity loan, and a cash-out refinance. They differ in how funds are delivered, how interest is charged, and how the loan is structured.
| Feature | HELOC | Home Equity Loan | Cash-Out Refinance |
|---|---|---|---|
| Funds | Revolving line you draw as needed | One lump sum | New first mortgage with cash back |
| Interest rate | Often variable | Often fixed | Often fixed or adjustable |
| Repayment | Draw period, then repayment period | Fixed monthly payments over a set term | Replaces existing first mortgage |
| Closing costs | May be lower or partially waived | Similar to other mortgage loans | Usually highest because new first mortgage |
| Best for | Ongoing or uncertain expenses | One-time, predictable expense | Lowering first mortgage rate while taking cash |
For more detail, compare cash-out refinance and secured vs. unsecured loans. The right choice depends on your goal, budget, risk tolerance, and how long you need the money.
Risks and Responsible Use
A HELOC puts your home on the line. If you fall behind, the lender can foreclose, even if you have paid on time for years. Variable rates can increase monthly payments, and a draw period that ends with a large principal payment can strain a budget. Using a HELOC for discretionary spending or to cover ongoing deficits can turn short-term borrowing into long-term debt.
Before borrowing, consider how you would repay the line if your income fell or rates rose. Make a plan for the repayment period, not just the draw period. Keep documentation of how you use the funds, especially if you may claim a tax deduction. The CFPB mortgage tools and HUD home buying information can help you review mortgage choices and avoid costly mistakes.
A HELOC can be a useful financial tool when used carefully, but it is not free money and it is not right for every goal. Compare offers, read all disclosures, and ask questions until you understand the terms.
When a HELOC May Fit
A HELOC may fit when you need flexible access to funds over time and you have stable income to repay the line. Examples include staged home improvements, a bridge between expenses, or a reserve for planned projects. It may be less suitable for one-time costs, because a home equity loan offers a fixed lump sum and predictable payments.
If you need a specific amount for a single expense, compare a home equity loan and a personal loan. A personal loan is usually unsecured, so the home is not collateral, but it may have a higher rate. See what a personal loan is and personal loan vs. line of credit for context.
Whichever option you consider, start with your budget and repayment plan. A lower rate does not help if the payment does not fit your income. Review the CFPB loan tools and speak with a housing counselor or financial professional if you are unsure.
