It’s not the number of credit cards you have — it’s what you do with them — says the creator of the most widely used credit scoring model.
“Yes, you can get an excellent FICO score if you have only one credit card — or no credit cards. The key is how you use the credit that you are granted,” says Craig Watts, spokesman for FICO, in an email. “People with excellent FICO scores generally follow our three guidelines: 1) pay all bills on time (never be late); 2) if you do have one or more credit cards, keep the balances on your card(s) low, the lower the better; and 3) take on new credit obligations sparingly and only when needed. If you just follow those three guidelines consistently over time, you won’t need to ask anyone how many credit cards you ‘should’ have.”
While you may not need to have any plastic, you do need to have used some form of credit in order to have a credit history. On FICO’s website, you can see that “types of credit used” makes up the smallest portion (10 percent) of the categories that influence your credit score. So you might not have a credit card, but having a student loan and a mortgage, for example, would show lenders that you can act responsibly with other types of loans. And that good borrowing behavior would show up on your credit report and help boost your credit score.
As for that last tip from FICO, think carefully about when you decide to open any new lines of credit. That’s because your credit score can suffer a temporary drop when you apply for a new account. Therefore, if you were looking to qualify for a mortgage in the near future, for example, it wouldn’t be a good time to also apply for a bunch of credit cards or rack up balances on those you already have.
It can still be a good idea to have multiple cards, though. During the worst days of the economic recession, card issuers were quick to close accounts or cut credit lines in an effort to protect themselves from losses. And while that’s less true now, having multiple cards can minimize the risk that you’d be left with no credit if one of your cards was closed by the bank.
If a bank does decide to close an account or cut your credit line, that action can cause an increase in your utilization ratio. That’s the comparison between the debt you have and the total credit you have access to — and it’s a factor in determining your credit score.
For example, say you currently have $2,000 in overall credit card debt and a combined total of $10,000 available on all your credit card lines. But then the bank closes a card with a zero balance and a $5,000 line of credit, cutting your total available credit in half. That leaves you with much more debt compared to your total available credit ($2,000 compared to $5,000, in this example) — increasing that utilization ratio.
In the end, whether you have no credit cards or a handful, the key to a great credit score comes down to the basics — paying your bills on time and keeping debt levels low.
