Drilling down, the credit scores of consumers with only one credit card aren't necessarily higher or lower than consumers with more credit cards—or those with none at all. However, their average FICO Scores appear to vary far less than the population at large. For example, while average FICO Scores at the state level range from 680 to 743 as of Q1 2024, the range in average FICO Scores is much narrower—ranging from a 700 to 739 FICO Score—when just examining consumers using only a single card.
Easier to Handle One Card
Possible explanations include fewer delinquencies on these consumers' credit reports, as Experian data shows, instead of the average of four or more. In addition, as previously mentioned, they also have lower utilization rates than consumers at large.
Regardless, although having a single card card doesn't necessarily improve your credit, those with a single credit card are more likely to be Steady Eddies versus other consumers: A higher percentage of one-card consumers have good credit scores, and a lower percentage have poor scores.
Balance Transfer Offers Can Help Reduce the Number of Cards You Carry
If you have more than one credit card with a balance and want to consolidate all those monthly payments and save on interest in the process, then a balance transfer credit card offer is one way to do it.
Typically, balance transfer offers allow you to transfer interest-accruing balances from other credit cards to the new balance transfer card, with the transferred balances not being charged interest for a number of months (often 12 to 21 months). Borrowers may still have to pay a balance transfer fee amounting to 3 to 5% of the balances transferred.
Of course, you'll need a reasonably good credit score to receive better balance transfer offers, and a missed payment can quickly restart the interest-accruing meter on the transferred balances. But those who can stick to a plan of reducing those transferred balances may not only have bought themselves some extra time and savings, but also more room in their pocket free of excess plastic.
Methodology: The analysis results provided are based on an Experian-created statistically relevant aggregate sampling of our consumer credit database that may include use of the FICO Score 8 version. Different sampling parameters may generate different findings compared with other similar analysis. Analyzed credit data did not contain personal identification information. Metro areas group counties and cities into specific geographic areas for population censuses and compilations of related statistical data.
