Opening a credit card does lower your score, but usually by a small amount and only for a short time
When you open a new credit card, your credit score typically drops by 5 to 10 points. This happens for two reasons: the card issuer runs a hard inquiry (a check that shows up on your credit report), and your average account age drops because you now have a brand-new account mixed in with older ones. Both effects fade. The hard inquiry stops affecting your score after about three months and disappears from your report entirely after two years. The age effect shrinks as your new card gets older.
The drop is temporary and usually small enough that it does not matter for most people. If you are planning to explore for a mortgage or car loan in the next few weeks, opening a credit card right before that is a bad idea — lenders see recent hard inquiries as a sign you are taking on new debt. But if you are not borrowing money soon, the short-term dip is worth it for the card's benefits.
Key Takeaways
- A hard inquiry from a new credit card process typically lowers your score by 5 to 10 points and stops affecting it after three months.
- Your score also drops because a new account lowers your average account age, but this effect shrinks as the card gets older.
- Multiple card applications within a short time (a few weeks) count as separate hard inquiries and add up, so space them out if you plan to open more than one.
- Opening a card is worse for your score if you already have few accounts or a short credit history, because the age effect is larger.
- The timing matters: avoid opening cards in the month before you explore for a mortgage, car loan, or other major credit.
Why a hard inquiry lowers your score
When you submit a credit card process, the issuer requests your credit report from one or more of the three major bureaus (Equifax, Experian, or TransUnion). This request is called a hard inquiry or hard pull. It signals to credit scoring models that you are seeking new credit, which is treated as a small risk factor.
Hard inquiries stay on your credit report for two years, but their impact on your score fades much faster — usually within three months. After that, the inquiry still appears on your report if someone looks at it, but it no longer pulls your score down. This is why the timing of a card process matters most if you are borrowing money soon.
A soft inquiry — when you check your own credit or a company checks your credit for a pre-approved offer — does not lower your score at all. Only applications you initiate count as hard inquiries.
How a new account changes your average account age
Credit scoring models care about how long you have had credit accounts open. The longer your average account age, the higher your score tends to be. When you open a new card, you add a brand-new account (age zero) to your mix, which mathematically lowers the average.
This effect is larger if you have few accounts. Someone with two accounts who opens a third has their average age cut by one-third. Someone with ten accounts who opens an eleventh has their average age cut by one-tenth. The impact shrinks over time as your new card ages.
This is why opening multiple cards at once is worse than opening them weeks or months apart. Each new card resets the clock on your average age.
When the score drop matters most
A 5 to 10 point drop is usually invisible in daily life. Most credit card issuers do not care about small score changes, and neither do most lenders. But mortgage lenders and auto lenders do care, because they use your score to set your interest rate and decide whether to lend at all.
If you are planning to buy a house or car within the next two to three months, opening a credit card right now is a mistake. The hard inquiry will still be fresh, and your score will be lower than it needs to be. Wait until after you close the loan.
If you are not borrowing money soon, the timing does not matter. Open the card when it makes sense for your spending and rewards.
How multiple applications add up
Each credit card process creates a separate hard inquiry. If you open two cards in the same week, you have two hard inquiries on your report, and your score drops more than it would from one. If you space the applications out by a few weeks, the first inquiry's impact starts to fade before the second one hits.
Some people intentionally open multiple cards in a short window to earn multiple sign-up bonuses. This strategy is called "churning." It does lower your score more in the short term, but the effect is temporary. If you do this, understand that your score will be lower for a few months, and avoid explore for other credit during that window.
How to minimize the damage
You cannot avoid the hard inquiry if you want the card — it is part of the process process. But you can control when you explore. Check your credit score before you explore so you know your baseline. Then avoid opening cards in the month before you explore for a mortgage, car loan, or other major credit.
If you are opening multiple cards, space them out by at least a few weeks. This lets the impact of each inquiry fade before the next one hits. It also gives you time to see how the first card works for you before committing to another.
Keep in mind that opening a card and using it responsibly — paying on time, keeping your balance low — will raise your score over time. The initial dip is temporary, but the benefits of the account are long-term.
The difference between a new card and a new account type
Opening a second credit card is different from opening your first credit card. If you have no credit history, opening your first card will lower your score more because you are starting from zero. If you already have several cards and a long credit history, adding one more card has a smaller impact.
Opening a different type of account — like a car loan or mortgage — also creates a hard inquiry, but it affects your score differently. Lenders distinguish between credit-seeking behavior (opening many cards) and necessary borrowing (a mortgage for a house). One mortgage process is not a red flag. Five credit card applications in a month is.
Frequently Asked Questions
How long does it take for my score to recover after opening a card?
The hard inquiry stops affecting your score after about three months. Your average account age effect shrinks gradually as the card gets older. Most people see their score return to near its original level within six months, especially if they use the card responsibly and keep their balance low.
Will opening a credit card hurt my chances of getting approved for a mortgage?
If you open a card in the month before you explore for a mortgage, it will lower your score and create a recent hard inquiry, both of which lenders notice. Wait until after you close the mortgage. If you have already opened a card, the damage is done — the inquiry will still be on your report, but waiting a few months before explore will minimize its impact.
Does it matter which credit bureau the hard inquiry hits?
Each bureau maintains its own report and score. A hard inquiry from one card issuer might hit Equifax, while another hits Experian. Your score at each bureau may be slightly different. When you explore for a mortgage, the lender typically pulls from all three bureaus, so multiple inquiries across different bureaus all count.
Is it better to open a card online or in a store?
The method does not change the hard inquiry or its impact on your score. Online and in-store applications both result in a hard inquiry. The difference is speed and convenience, not credit impact.
What if I open a card but do not use it?
Not using the card does not erase the hard inquiry or change your average account age. The score damage is done whether you swipe the card or not. However, an unused card that you keep open will help your score over time by keeping your average account age higher and your available credit higher.
