Yes—but probably not as much as you think, and the damage is typically temporary. Opening a new credit card does affect your credit score, but the impact depends on several factors unique to your financial profile.
When you apply for a credit card, the issuer requests a hard inquiry into your credit report. This hard pull is recorded and can lower your score by a modest amount—often somewhere in the range of a few points to around 10 points, though the exact impact varies by credit scoring model and your current profile.
More significant is what happens if you're approved: the new account itself gets added to your credit history. This has two competing effects on your score.
The hard inquiry appears on your credit report and affects your score for roughly 12 months, though its influence on your score typically fades after a few months.
The new account lowers your average age of accounts (a factor in credit scoring), which can further reduce your score in the short term. Over time, as the account ages, this negative effect diminishes. Additionally, a new account temporarily increases your total available credit, which can actually help your credit utilization ratio—the percentage of your available credit you're using. A lower utilization is better for your score.
How much your score drops—and how quickly it recovers—depends on:
For most people, the impact of opening a single new card is modest and temporary. The hard inquiry's influence fades significantly after a few months and disappears from your report after 12 months. The new account itself becomes less of a drag as it ages.
If you're planning to apply for major credit (a mortgage or auto loan) in the coming months, however, timing matters. Multiple hard inquiries or a brand-new account on your report during that window could influence a lender's decision.
A new card's improved credit utilization ratio—especially if you're currently using a high percentage of existing credit—can sometimes offset the initial score dip relatively quickly. This depends entirely on how you use the new account and manage existing balances.
The decision to open a new card involves weighing this temporary score impact against the card's benefits for your specific financial situation and goals. Only you can determine whether the tradeoff makes sense.
