Credit Cards

Dear Liz: You should tell people that they can help their credit score more by not paying their credit card bills in full each month. By not paying in full, but paying the minimum or more each month, it shows the card issuer that you can handle credit wisely and encourages them to raise the limit. This pushes the utilization down.

Answer: There’s nothing wise about carrying credit card debt. The idea that you need to carry a balance to have good scores is a stupid, expensive myth that needs to die.

People who spread this myth don’t understand how balances are reported to the credit bureaus and subsequently used in credit scores. Credit card issuers typically don’t report your balance on the day after you pay your bill. They may report your last statement balance, or the balance on a certain day each month. That’s the balance that credit score formulas have long used to calculate your scores. The scoring formulas traditionally couldn’t see whether or not you carried a balance from month to month, so there was no reason to do so and incur expensive interest.

Recent credit reporting changes will make carrying a balance an even worse idea. Some card issuers have started reporting payment patterns — essentially telling the bureaus which people consistently pay their balances in full and which don’t. That’s because research has shown that people who pay off their credit card bills are significantly less likely to default than those who carry a balance. Mortgage lenders already are considering this information when making loans, even though it’s not something that factors into the credit scores most of them currently use.

Although there’s no advantage to carrying a balance, there is a huge advantage to lightly but regularly using the credit cards you have. That’s what actually shows scoring formulas and lenders that you can responsibly manage credit.
