How a HELOC Affects Your Credit Score (and How Much)

The question we hear most often from homeowners weighing a HELOC is not about the rate. It is about their credit: will applying drop my score, and will a big balance on the line make me look maxed out?

The honest answer is that a HELOC touches your credit in four separate places, and they do not all point the same direction. The application costs less than most people expect. The payment history matters far more. And the part people worry about most, utilization, depends on which scoring model the lender is looking at.

Here is how each piece works, using what FICO, Experian, and the Consumer Financial Protection Bureau actually say.

What Actually Goes Into a FICO Score

It helps to start with the scorecard. According to myFICO, FICO Scores are built from five categories:

Those weights are general. FICO notes that how much each factor matters varies from one person's credit file to the next. But they tell you where to focus: the two biggest categories are how you pay and how much you owe.

1. The Application: A Hard Inquiry

When a lender pulls your credit to approve a HELOC, it creates a hard inquiry. myFICO says that for most people, one additional inquiry takes less than five points off their FICO Scores. Inquiries stay visible on your report for up to two years, but they only affect FICO Scores for one.

There is one catch worth knowing. FICO groups rate-shopping inquiries so that several applications in a short window count as one: 45 days in the newest FICO versions and 14 days in older ones. myFICO's guidance names mortgages, auto loans, and student loans as the loan types this applies to. It does not mention HELOCs specifically, so do not assume that applying at five banks will be treated as a single inquiry.

That is a practical argument for comparing lenders through one channel rather than filling out applications everywhere. A broker can compare HELOC pricing across several lenders through one channel, which is the core of the difference between a mortgage broker and a bank.

2. The New Account: Your Average Age Drops

Length of credit history is 15% of a FICO Score, and part of it is the average age of your accounts. Experian notes that opening a HELOC lowers that average, which can pull a score down slightly. The effect fades as the line ages.

There is an upside on the other side of the ledger. Experian points out that a HELOC can strengthen a thin credit file with few accounts, and a HELOC is considered a revolving account for credit mix. For most homeowners who already have a mortgage and a couple of cards, the mix effect is small either way.

3. Utilization: The Part Most People Get Wrong

Utilization is the share of your available revolving credit you are using. On credit cards it is a big deal: a card at its limit hurts. So it is natural to assume that drawing $90,000 on a $100,000 HELOC would make you look 90% maxed out.

Under FICO, it generally does not. myFICO states that the FICO Score generally excludes HELOCs from credit utilization calculations. The line still counts for credit mix, and its payment history, amount owed, and age can still affect your score, but a large drawn balance typically is not scored the way a maxed-out card would be.

VantageScore is different. Experian notes that VantageScore may include the HELOC's balance and credit limit in its utilization assessment. Here is what that difference looks like on one illustrative household:

Same household, same behavior, very different number depending on whether the model counts the line. This is arithmetic, not a prediction of any score. The takeaway is simple: if you plan to apply for other credit soon after drawing heavily on a HELOC, ask which scoring model that lender uses.

4. Payment History: The Part That Actually Matters

Payment history is 35% of a FICO Score, the largest single category. Experian notes that a HELOC is reported to all three credit bureaus, that on-time payments help, and that payments 30 days or more late damage your scores. The CFPB says credit reporting companies can generally report most negative information, including late payments, for seven years.

Two HELOC-specific details make this worth planning around:

• The payment can change. Most HELOCs carry a variable rate, so the minimum payment moves when the index does. The Fed raised its target range this week, which is the kind of change that typically flows through to variable HELOC payments. We covered what that means in the Fed's September decision.
• The payment jumps when the draw period ends. Principal becomes mandatory and the schedule gets short. If you have not planned for it, that is where late payments start. The mechanics are in HELOC draw period vs. repayment period.

Autopay for at least the minimum is the cheapest insurance there is.

What About Closing or Having the Line Reduced?

Paying off a HELOC and closing it does not erase it. Experian notes that a closed account can stay on your report for up to 10 years, and its payment history continues to count. Because FICO generally leaves HELOCs out of utilization, closing one usually matters less to a FICO Score than closing a large credit card. Under a model that does count the line, losing its limit could raise your utilization on whatever balances remain.

The same logic applies if a lender freezes or reduces your line, which the CFPB notes HELOC agreements generally allow when home values fall or your finances change for the worse.

HELOC, Cash-Out Refi, or Card: The Credit Angle

Credit impact is rarely the deciding factor, but it is one input. With the 30-year fixed averaging 6.95% as of September 17, 2026, up from 6.76% a week earlier according to Freddie Mac, homeowners holding a low pre-2022 first mortgage have little reason to refinance it just to reach their equity. That is the case for a second lien laid out in accessing equity without refinancing. If you are choosing between a line and a fixed lump sum, our comparison of a home equity loan vs. a HELOC covers how each behaves. And if you work for a large California employer, check whether a relationship-based discounted rate is available to you before you shop retail.

What we would not do is let fear of a few inquiry points keep you on high-rate credit card debt if a secured line could cost less. The inquiry fades in a year. The interest does not.
