Do Credit Cards Hurt Your Credit Score? Four Reasons They Don’t

I am fairly new to collecting points and miles. Before I started, I was convinced that taking out new credit cards would torch my credit. I am not going the way of 50 Cent. I wouldn’t want my future house with 25 bathrooms to go into foreclosure. Turns out, I was worried for nothing. My credit score actually went up. You can take out credit cards and keep your bling. There are several reasons credit cards do not hurt your credit score, and once you understand how the score is built, the fear mostly evaporates.

Do Credit Cards Hurt Your Credit Score? The Short Answer

No, not if you use them like an adult. Opening a new card causes a small, temporary dip from the hard inquiry, but the two biggest pieces of your score — paying on time and keeping your balances low relative to your limits — actually improve when you add cards and behave yourself. Here is what makes up a FICO score, the version most lenders actually use when you go for a car loan or mortgage:

• Payment history — 35%. Are you paying on time? The single biggest factor.
• Amounts owed (credit utilization) — 30%. How much of your available credit you are using.
• Length of credit history — 15%. Older accounts help.
• Credit mix — 10%. A variety of account types.
• New credit — 10%. Recent inquiries and newly opened accounts. This is the only bucket new cards ding, and it is the smallest one.

Notice that the scary part — applying for cards — lives in a 10% bucket, while the two things responsible cardholders nail account for a combined 65%. The math is on your side. If you are still building your stash, my guide to earning travel points for beginners and my roundup of the best miles and points credit cards for beginners are good companions to this post.

1. Why Is Payment History the Most Important Factor?

Payment history accounts for 35 percent of your credit score — far more than any hard credit pull. If you pay your bills on time, your score climbs. Add more credit cards and pay those on time, and you are simply feeding more on-time payments to the credit bureaus every month. As long as you pay on time, more credit cards do not hurt your credit score in the part of the formula that matters most — they pad your track record.

Organization is the whole game here, because a single missed payment can knock a healthy score down by a brutal amount. All of our credit cards are set to autopay the statement balance each month, so nothing slips through the cracks while I am busy refereeing a sibling dispute over the last fruit snack. I also keep an eye on transactions and balances across every card with a budgeting app — partly for the budget, mostly so that $0.69 charge in Brazil doesn’t go through on my watch (this actually happened). A heads-up if you are reading an older version of this advice: Intuit shut down Mint on March 23, 2024, and pushed everyone to Credit Karma. Credit Karma, Monarch, Rocket Money, Empower, and YNAB all do the same job — pick whichever one you will actually open.

2. How Does Credit Utilization Affect Your Score?

Credit utilization — your debt-to-credit ratio — accounts for 30 percent of your credit score. This is the single biggest reason my score went up when I took out more cards. If you have more available credit but spend the same amount, your utilization ratio drops, and a lower ratio is exactly what the score rewards. More credit cards do not hurt your credit score here; they actively help.

A quick example: if you carry $2,000 in spending across $10,000 of total limits, that’s 20% utilization. Get approved for a new card with a $5,000 limit, keep spending the same $2,000, and you are suddenly at about 13%. You did nothing differently except open an envelope.

The takeaway is to not increase your spending just because you have more credit. You don’t need three tigers. You aren’t Mike Tyson. Along the same lines, pay your bills in full every month. Any benefit you get from points and miles will be more than canceled out by interest payments. If you need to carry a balance, hold off on taking out new cards for now and tackle the debt first.

3. Does Keeping Old Credit Cards Help Your Score?

Yes. Length of credit history is 15 percent of your score, so once you take out credit cards, hold onto them — closing an old card can shorten your average account age and shrink your total available credit, nudging your utilization the wrong way. If you don’t want to pay the annual fee after the first year, ask for a retention offer before you cancel. Card companies will often hand you a statement credit or bonus points to keep you around, and at a minimum most will let you downgrade to a no-annual-fee version of the card.

One important caveat: do not attempt to downgrade until after the second-year annual fee posts. Some issuers — American Express in particular — have been known to claw back your intro bonus if you do a product change within the first year. Many issuers will also refund the annual fee if you call within a short window after it posts (often around 30 days, but it varies, so don’t assume), which gives you a little breathing room to decide. New credit cards can bring your score down a touch at first, but just like the Golden Girls, it improves with age.

4. How Long Do Hard Inquiries Affect Your Credit?

Not long, and not by much. Hard pulls are a small slice of the 10% “new credit” bucket. If a single inquiry affects your score at all, the hit is usually minor and temporary, especially if you already have good credit — it typically fades within several months and stops counting entirely after a couple of years.

That said, don’t waste a hard pull on a card you have little chance of getting. Before you apply, a quick search will tell you the general score range issuers tend to approve, plus any application rules they enforce. The order in which you apply matters more than people expect:

• Chase 5/24. Chase will likely decline you if you’ve opened five or more personal credit cards from any issuer in the last 24 months. Authorized-user accounts count toward that total, so do Chase cards first if you want them.
• Amex welcome bonuses. American Express enforces a “once per lifetime” bonus rule on most cards and limits how many of its cards you can hold at once. Enforcement has loosened somewhat over the years, but plan as if it’s firm.
• Everybody else. Most issuers get nervous if you’ve opened a lot of cards recently — some more than others.

The individual rules of each company change constantly, and The Points Guy publishes a lot of solid, regularly-updated content on approval odds for specific cards. Map out the cards you want over the next year or two, space out your applications, and apply in a strategic order. If you’re worried about a card going dormant while you wait, here’s how often you should use a card to keep it active.

How Do You Check and Fix Your Credit Report?

Check your credit report regularly. You can now pull free reports from all three bureaus — Equifax, Experian, and TransUnion — every week at AnnualCreditReport.com; the pandemic-era weekly access was made permanent in October 2023, so the old “once a year” rule is gone for good. Better yet, for ongoing monitoring I use NerdWallet. The free tool breaks down your score, accounts, and balances, sends alerts, and even simulates what will happen to your score if you do something like apply for a new card or miss a payment.

One thing to know so the numbers don’t confuse you: free tools like NerdWallet show a VantageScore, while most lenders pull a FICO score. The two move together but rarely match exactly, so treat the free number as a trend line, not the figure your mortgage officer will quote.

Is there something on your report that shouldn’t be there? Appeal it. My husband recently had a doctor’s office accidentally send him to collections — we only found out because the app flagged that his score had dropped 47 points overnight. After going all Alec Baldwin on the doctor’s office, I filed disputes with the bureaus it had been reported to. Both deleted the entry within hours in our case, which was faster than I expected; by law, bureaus have up to about 30 days to investigate, so don’t count on same-day miracles. The bill had already been paid in full, so the entry was a flat-out error — but if something looks off on your report, file a dispute and see what happens.

Final Thoughts

Credit cards get a bad rap. True, the interest rates and fees are ridiculous, but if you can manage them, they are incredibly beneficial. Used responsibly, the cards that scared me actually raised the score I was so worried about wrecking.

If you don’t have good credit yet, work on it before you chase sign-up bonuses. Pay your bills on time and shrink your debt-to-credit ratio by paying down balances. Bad credit costs you real money — worse interest rates on car loans and mortgages, plus all the great card opportunities you’re locked out of.

Points and miles have let us travel without an opportunity cost. Don’t let fear of some imaginary credit-score apocalypse keep you on the sidelines. Set up autopay, pay your bills in full each month, get organized, and space out your applications. You will be fine. Whatever your chosen mode of transportation, use your points and miles to get out there and make memories.

Frequently Asked Questions

Does applying for a credit card hurt your credit score?

A new application triggers a hard inquiry, which can cause a small, temporary dip — usually minor if your credit is already healthy, and it fades over a few months. The longer-term effect of a new card is often positive, because the added credit limit lowers your utilization.

How many credit cards is too many?

There’s no magic number — what matters is whether you pay them all on time and keep balances low. The real limits come from issuer rules, like Chase’s 5/24 restriction and Amex’s caps, not from your score itself. If you can manage them, more cards mean more total credit and lower utilization.

Should I close a credit card I don’t use?

Usually not. Closing a card lowers your total available credit (raising utilization) and can shorten your average account age over time. If it carries an annual fee you’d rather not pay, ask for a retention offer or downgrade to a no-fee version instead of canceling. My full breakdown is in retention offers explained.

How often can I check my credit report for free?

Every week, from all three bureaus, at AnnualCreditReport.com — that weekly access became permanent in October 2023. Checking your own report is a “soft” inquiry and never hurts your score, so look as often as you like.
