Will opening a new card hurt my score?

Short-term, yes: about 5 points from the hard inquiry and a small drop from lowered average account age. Long-term, the added credit line usually nets positive within 6 months by lowering utilisation.

Should I cancel old cards I don't use?

Usually no. Closing a card lowers total available credit (raises utilisation) and shortens average account age once the closed account drops off in 10 years. If there's no annual fee, leave it open and use it once a year on a recurring bill.

What's the 5/24 rule?

Chase will not approve you for most of its consumer cards if you've opened 5+ personal cards (any issuer) in the past 24 months. Plan Chase applications first if you're chasing their bonuses.

How many credit cards should I have?

Direct Answer

Three to five active credit cards is the sweet spot for most adults: enough to optimise rewards categories and keep credit utilisation low, few enough to pay each one on autopay without losing track. Americans with FICO 800+ scores average about four open cards. Below two limits your utilisation buffer; above eight starts to look risky to underwriters.

Why the number matters less than the structure

Total available credit and on-time payment history drive 65% of your FICO score. Three cards with $30,000 combined limits and 5% utilisation outperform one card with $10,000 and 15% utilisation. The cards just need to be paid in full each month, every month.

When to add another card

Add a card when (a) it covers a category you spend $300+/month on with weak rewards (e.g. a 5% groceries card if you currently earn 1%), (b) the sign-up bonus exceeds the annual fee by 3× in year one, or (c) you need to lower utilisation and a balance transfer isn't an option.
