Dear Liz: I’ve received a notice stating that a retail credit card I’ve had for more than a decade will be converted to a Mastercard. I already have an American Express charge card and a Visa rewards credit card. I don’t need another credit card. But I’m concerned. Will the conversion hurt my credit scores? Or is having a credit card versus a retail card better for my credit scores?

Answer: Congratulations! Such conversions indicate you’ve been using the card and your other credit accounts responsibly. If you continue to do so, the new credit card could help your credit scores more than the retail card.

Although getting new plastic is both good and bad for your credit score, a credit card is typically factored into more FICO scoring variables than a retail card, said Ethan Dornhelm, FICO’s vice president of scores and predictive analytics.

“So to the extent that you have positive behaviors, it’s more likely to have a broader positive impact,” Dornhelm said.

The flip side is that if you mess up by missing a payment or running up big balances, those mistakes could have a greater effect on your scores, Dornhelm said.

Closing the account probably would be one of those mistakes, since closures reduce your available credit and in general should be avoided unless there’s a compelling reason, such as a too-high annual fee. The benefits that came with the retail card, such as discounts and free shipping, probably will transfer to the credit card, so you can continue to benefit from the account without worrying that it will hurt your scores.
