A home equity line of credit (HELOC) is a revolving credit line secured by your home. You can borrow, repay and borrow again up to a set limit during a “draw period,” often about 10 years, and then you enter a “repayment period” when borrowing stops and you pay down the balance. Most HELOCs have a variable rate tied to the prime rate. To apply, you need enough equity, steady income and acceptable credit, and you should compare several lenders’ rates, margins, fees and repayment terms before you sign.
Key takeaways
- The rate usually equals the prime rate plus a margin. As of October 16, 2026, the prime rate was 7.00% (Federal Reserve H.15).
- The lender caps your line using combined loan-to-value: all mortgage debt divided by your home’s value.
- Payments can jump sharply when the draw period ends. In our example, a $60,000 balance goes from $375.00 to $483.36 a month, or $559.28 if rates rise 2 points.
- Interest is tax-deductible only if you itemize and the money buys, builds or substantially improves the home that secures the line (IRS Publication 936).
- Your home is collateral, and the lender can freeze or cut the line if your home’s value falls significantly or your finances worsen.
How a HELOC works
Draw period
Once the line is open, you can draw money as you need it, usually by transfer, special checks or a card. You pay interest only on what you have borrowed, not on the full limit. The CFPB notes that the draw period could last 10 years. Many plans require only interest payments during this time, so the balance does not shrink unless you pay extra.
Some plans set a minimum amount for each draw, require a minimum balance or require an initial draw when the line opens. Read the plan’s transaction rules before you apply, especially if you want the line as a standby fund.
Repayment period
When the draw period ends, you can no longer borrow. The lender then sets a schedule to pay off the balance, often over 10 to 20 years, according to the CFPB. Some plans instead require the entire balance at once, a balloon payment. If you cannot pay or refinance a balloon, you could lose your home.
Variable rate tied to prime
A HELOC rate has two parts: an index and a margin. The most common index is the prime rate, which was 7.00% as of October 16, 2026, according to the Federal Reserve’s H.15 release. If your margin is 0.50 point, your rate is 7.50% and moves whenever prime moves. Some lenders offer a low introductory rate for the first several months, so ask what the rate becomes afterward.
Federal Regulation Z requires a dwelling-secured variable-rate contract to state the maximum rate that can be charged. Look for that lifetime cap, and any floor, in the disclosures. Some plans also let you convert part of the balance to a fixed rate, which is usually higher but predictable.
How much you can borrow: CLTV limits
Lenders limit HELOCs by combined loan-to-value (CLTV), the total of all loans on the home divided by its appraised value. Each lender sets its own maximum, and it can vary with your credit and the property, so ask before you apply. The example below assumes an 85% CLTV limit for illustration only.
Say your home is worth $450,000 and you owe $250,000 on your first mortgage. Your equity is $200,000. At an 85% CLTV cap, total debt can reach $382,500, so the largest possible line is $132,500. If you draw $60,000, your CLTV becomes 68.9%, which leaves a cushion if home values dip.
Fees to expect
Some lenders waive upfront costs and others charge them. The CFPB lists possible charges including an appraisal fee, an application fee that may not be refunded if you are turned down, and closing costs such as title search, recording, attorney and document fees. Ongoing costs can include an annual fee and transaction fees. Ask whether a “no closing cost” line requires you to keep it open for a minimum time or repay waived costs if you close it early.
Worked example: payment shock at the end of the draw
Continue the example. You draw $60,000 for a kitchen remodel. Your rate is prime (7.00%) plus an assumed 0.50 margin, or 7.50%. The plan has a 10-year interest-only draw period and a 20-year repayment period. All figures are EarlyPayoff calculations.
| Phase and scenario | Rate | Monthly payment | Change vs. draw period |
|---|---|---|---|
| Draw period, interest only | 7.50% | $375.00 | — |
| Repayment over 20 years, rate unchanged | 7.50% | $483.36 | +$108.36 (29%) |
| Repayment over 20 years, prime up 2 points | 9.50% | $559.28 | +$184.28 (49%) |
| Repayment over 10 years, rate unchanged | 7.50% | $712.21 | +$337.21 (90%) |
If the rate stayed at 7.50% the whole time, you would pay $45,000.00 of interest during the draw period and another $56,006.40 during repayment, for $101,006.40 in total on a $60,000 project. Paying as if the balance were a 30-year amortizing loan from the first month would cost $419.53 a month, only $44.53 more than interest-only, and would avoid most of the payment jump later.
HELOC vs. home equity loan vs. cash-out refinance
| Feature | HELOC | Home equity loan | Cash-out refinance |
|---|---|---|---|
| How you get money | Revolving line; draw as needed | Lump sum at closing | Lump sum; replaces your first mortgage |
| Rate type | Usually variable (prime + margin) | Usually fixed | Fixed or adjustable |
| Effect on first mortgage | Keeps it; adds a second lien | Keeps it; adds a second lien | Pays it off; new rate applies to the whole balance |
| Upfront costs | Often low or waived; varies | Closing costs; varies | Full mortgage closing costs |
| Best for | Costs spread over time or uncertain amounts | One known expense, stable payment | When the new rate is not much higher than your current rate |
| Main risk | Rising rates, payment shock, line freezes | Fixed payment plus first mortgage | Losing a low first-mortgage rate; resetting the term |
A cash-out refinance looks very different if your first mortgage has a low rate. In the example, the $250,000 balance is at 3.25% with 25 years left, for a principal and interest payment of $1,218.29. Refinancing to $310,000 at the Freddie Mac 30-year average of 7.40% (week of October 15, 2026) would raise it to $2,146.38, an increase of $928.09. Keeping the first mortgage and adding the HELOC costs $1,593.29 during the draw and $1,701.65 during repayment at today’s rate.
In the first year, the refinance would cost $22,842.48 in interest, versus $12,527.38 for the old mortgage plus the HELOC, a gap of $10,315.10. That gap comes from repricing $250,000 of cheap debt, not from the $60,000 you actually need. For more on that trade-off, see when to refinance your mortgage.
Is HELOC interest tax-deductible?
Only in limited cases. IRS Publication 936 says interest on home equity loans and lines of credit is deductible only if the money is used to buy, build or substantially improve the home that secures the loan. Interest on a HELOC used for a car, tuition or credit card payoff is not deductible, no matter when the debt was taken out. Pub 936 notes that the 2025 tax law (the One Big Beautiful Bill Act) affected these rules; as of October 2026, the IRS guidance still limits the deduction this way, and qualifying debt counts toward the $750,000 cap on acquisition debt ($375,000 if married filing separately).
You also have to itemize. For 2026 the standard deduction is $32,200 for married couples filing jointly and $16,100 for single filers, so many households get no tax benefit at all. Keep receipts showing how the money was spent on the home.
How to apply for a HELOC
- Estimate your equity and CLTV. Use a realistic home value and your current mortgage balance. Decide how much you truly need rather than the maximum available.
- Check your credit and debts. Review your credit reports for errors and calculate your debt-to-income ratio including a fully amortizing HELOC payment.
- Gather documents. Expect pay stubs, tax returns or W-2s, mortgage statements, homeowners insurance and property tax information.
- Compare at least three offers. Lenders must give you HELOC disclosures and a CFPB brochure with the application. Compare the index, margin, introductory rate, rate cap and floor, fees, draw and repayment lengths, minimum payment rules and any balloon payment. In general, a lender cannot collect a nonrefundable fee until three business days after you receive these disclosures.
- Appraisal and underwriting. The lender verifies value, income and title. Ask whether an automated valuation is used instead of a full appraisal.
- Close and wait out the rescission period. For a HELOC on your principal home, you can cancel until midnight of the third business day after closing. The lender cannot release funds until that period ends.

Risks and when a HELOC is a bad idea
- Foreclosure risk. The CFPB warns that if you fall behind on a HELOC, you could lose your home. Do not turn unsecured debt, such as credit cards, into debt secured by your house unless you have fixed the spending that created it.
- Line freezes. Regulation Z lets a lender block new draws or lower your limit if your home’s value falls significantly below its appraised value or your finances change materially. Do not rely on an unused HELOC as your only emergency fund.
- Payment shock and rate risk. Interest-only payments look affordable but can rise sharply when repayment starts or when prime rises.
- Short time in the home. If you plan to sell within a few years, the balance comes out of your sale proceeds, and upfront fees may not pay off.
- Schemes that promise faster mortgage payoff. Routing your paycheck through a HELOC does not change the math of interest; it adds variable-rate risk and fees. Extra principal payments on your mortgage are simpler.
If the line is frozen, the CFPB suggests asking the lender why, checking your credit reports for errors, requesting that a new appraisal be accepted, or shopping for another line to pay off the first. For paying down other balances first, see which debt to pay off first.
Frequently asked questions
What credit score do I need for a HELOC?
There is no single federal minimum; each lender sets its own standards along with CLTV and debt-to-income limits. Higher scores and more equity generally earn a smaller margin. Ask each lender for its requirements before you allow a hard credit check.
Can I pay off a HELOC early?
Usually yes, and paying principal during the draw period cuts both interest and later payment shock. Some plans charge an early closure fee or recapture waived closing costs if you close the line within a few years, so you can often pay the balance to zero and leave the line open instead.
Can a lender cancel or freeze my HELOC?
A lender can block further draws or reduce your limit in specific situations listed in Regulation Z, including a significant drop in home value, a material change in your finances or a default on a material obligation. The freeze is meant to be temporary: credit must be restored once the condition ends, and the lender may require you to request reinstatement in writing. It cannot charge a fee to reinstate the line.
Do I get a Loan Estimate for a HELOC?
No. HELOCs use separate disclosures that list the APR, variable-rate details, payment terms, fees and draw rules, along with a CFPB brochure. Use those disclosures to compare offers side by side.
Is a HELOC better than a personal loan?
A HELOC usually has a lower rate because your home secures it, but that also means more is at stake if you cannot pay. A personal loan has a fixed payment and no lien on your home. For smaller or shorter-term needs, the safety of an unsecured loan may be worth a higher rate.
