Opening a new credit card will lower your score temporarily, usually by 5 to 10 points, because the bank runs a hard inquiry and adds a new account to your credit history. The damage is smallest if you already have several cards, largest if you have very few. The dip fades within a few months as the account ages and you build a payment history.
Key Takeaways
- A hard inquiry (the bank checking your credit to decide whether to approve you) causes a small, temporary drop that typically disappears within three to six months.
- Opening the account itself adds a new line to your credit report, which lowers your average account age and can reduce your score by a few more points.
- The long-term effect is usually positive if you keep the card open and pay on time, because you gain available credit and a longer payment history.
- Opening multiple cards in a short time (within 30 days) compounds the damage, so spacing applications out by at least a few months limits the impact.
- The score hit matters least if you are not planning to borrow money in the next three to six months — lenders see recent inquiries as a sign of active credit-seeking.
Why a Hard Inquiry Lowers Your Score
When you submit a credit card process, the bank 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 appears on your credit report and counts as a small negative factor in your credit score calculation.
A single hard inquiry typically reduces your score by 5 to 10 points. The exact amount depends on your current score and credit history. If your score is already low or you have few accounts, the percentage impact may feel larger, but the point drop is usually the same. The inquiry stays on your report for two years but stops affecting your score after about three to six months.
Soft inquiries — the kind that happen when you check your own credit or when a company pre-screens you for an offer — do not lower your score at all. Only applications you initiate trigger a hard inquiry.
How a New Account Changes Your Credit Mix
Once the bank approves you, the new card account appears on your credit report. This affects your score in two ways. First, it lowers your average account age. If you have had three cards for five years each, your average age is five years. Adding a brand-new card drops that average to four years. Older accounts are weighted more heavily in your score, so this dip is real but small — usually 2 to 5 points.
Second, the new account changes your credit mix, which is the variety of credit types you hold (credit cards, auto loans, mortgages, and so on). Adding a new credit card does not change your mix much if you already have other cards, but it can help if you have only one type of credit. This effect is positive and small, so it does not offset the account-age loss right away.
Together, the hard inquiry and new account typically lower your score by 10 to 15 points in the first month. This is temporary. As the account ages and you make on-time payments, the score recovers and usually climbs higher than it was before.
When the Damage Is Worst
The score hit is largest if you have very few credit accounts to begin with. Someone with two credit cards will see a bigger percentage drop from opening a third than someone with ten cards. Similarly, if your credit history is short (you have been borrowing for only a year or two), a new account has more weight in the calculation.
Opening multiple cards in a short window makes the damage compound. Each hard inquiry is a separate negative mark, and each new account lowers your average age again. If you open three cards in one month, you might see a 30-point drop instead of a 10-point one. Spacing applications at least 30 days apart, and ideally two to three months apart, keeps the impact smaller.
The timing also matters if you are planning to borrow money soon. Lenders see multiple recent hard inquiries as a sign that you are actively seeking credit, which can make them nervous about your ability to repay. If you are planning to explore for a mortgage or auto loan within the next six months, opening new credit cards beforehand can work against you.
How Long the Score Drop Lasts
The hard inquiry stops affecting your score after three to six months, though it remains visible on your report for two years. Most scoring models weight recent inquiries more heavily, so older ones matter less and less.
The new account itself stays on your report for as long as you keep it open, and it continues to age. After about six months of on-time payments, the account begins to help your score more than it hurts it. After a year, the positive effects (available credit, payment history, account age) usually outweigh the initial damage.
If you close the card after a few months, the account does not disappear from your report when ready. It stays there for seven to ten years, marked as closed, and continues to age. Closing a card can actually hurt your score more than opening one, because you lose the available credit without losing the account from your history.
How to Minimize the Impact
If you are planning to open a new card, space it out from other credit applications. Do not explore for a card, an auto loan, and a mortgage all in the same month. Wait at least two to three months between applications so each hard inquiry has time to fade from the calculation.
Before you explore, check whether the bank offers a pre-qualification or pre-approval process that uses a soft inquiry instead. Some issuers let you see whether you are likely to be approved without triggering a hard pull. This is not a may provide, but it can help you avoid unnecessary inquiries.
Once you have the card, the best thing you can do is use it responsibly. Make at least the minimum payment on time every month, and keep your balance well below the credit limit. A card that sits unused does not help your score, but one with a zero balance and a perfect payment history helps it grow. After six months to a year, the score recovery will be noticeable.
When Opening a Card Makes Sense Despite the Hit
A temporary score drop is worth it if you are not planning to borrow money in the near term. If your next mortgage or auto loan process is three years away, a 10-point dip now is irrelevant. The card will have aged, your payment history will be longer, and your score will be higher overall.
Opening a card also makes sense if you are carrying high balances on existing cards. A new card with a zero balance lowers your overall credit utilization (the percentage of available credit you are using). If you have $5,000 in balances spread across $10,000 in available credit, you are using 50 percent. Adding a card with a $5,000 limit brings your total available credit to $15,000, dropping your utilization to 33 percent. This improvement can offset the score hit within a few months.
The key is to have a reason beyond the score itself. Open a card because you need the credit, want the rewards, or are working to improve your credit mix — not because you are trying to game your score. The score will follow.
Frequently Asked Questions
How many points will my score drop when I open a new card?
Most people see a drop of 5 to 15 points depending on their current score, credit history, and how many accounts they already have. The hard inquiry alone causes 5 to 10 points of damage. The new account adds another 2 to 5 points. The exact number varies by scoring model and bureau.
Does it matter which credit bureau runs the inquiry?
Not really. Different banks pull from different bureaus, and your score at each bureau may be slightly different. A hard inquiry at one bureau affects only your score at that bureau, but most lenders check all three, so the impact is usually spread across all three reports.
Will opening a card hurt me if I am not planning to borrow money?
No. If you do not need a mortgage, auto loan, or other credit in the next six months, the score drop is temporary and harmless. The card will help your score in the long run if you use it responsibly and keep it open.
Can I undo the damage by closing the card right after I open it?
No. Closing the card does not remove the hard inquiry from your report, and it can actually hurt your score more by reducing your available credit. If you open a card, keep it open for at least a year to let the account age and the inquiry fade.
What if I open a card and then when ready regret it?
The hard inquiry is already done and cannot be undone. The best move is to keep the card open, use it occasionally to build a payment history, and let time do the work. Closing it quickly will not help your score and may hurt it more.
