Dear Liz: My husband has a lower credit score than I. He gives me a check every month from his personal checking account, which I deposit in our family account so I can pay our credit cards. He thinks that he needs to pay some of the cards directly in order to improve his score. He likes to send checks by mail, the old fashioned way (which drives me crazy!). Do you think this practice will improve his score?

Answer: The short answer is no. Credit scoring formulas don’t care who pays the bills, as long as the bills get paid on time.

Perhaps explaining some credit scoring basics would help.

People don’t have one credit score. They have many, because there are many different scoring formulas in use.

The most commonly used credit score is currently the FICO 8. There are many other versions of the FICO scoring formula, including some that are tweaked for different industries such as credit cards and auto loans. In addition, there are VantageScores, a rival formula created by the three major credit bureaus: Equifax, Experian and TransUnion.

Credit scores are based on the information in your credit reports at those bureaus, which are private companies that typically don’t share information. Because information can vary from bureau to bureau, your credit scores from each bureau may differ as well.

There’s no such thing as a joint credit report or a joint credit score, so couples typically will have different scores even if they have some joint accounts. How long a person has had credit, how many credit accounts the person has and the mix of credit types can be different, resulting in different scores.

Your husband may have lower scores than yours currently, but that’s not in itself a problem that needs to be fixed. If his scores are generally above 760 on the typical 300-to-850 scale, he’ll get the best rate and terms when applying for credit.

If his scores need improving, he should start by checking his credit reports from each of the three bureaus at www.annualcreditreport.com. (These reports used to be free just once a year, but you can now get them for free every week until April 2022.) He should dispute any information that’s inaccurate such as accounts that aren’t his or accounts showing missed payments if all payments were made on time.

He may be able to improve his scores by lowering how much of his available credit he’s using or adding an account or two. Opening accounts may temporarily ding his scores, but typically the new account will add points over time if used responsibly.

And do try to persuade him to stop sending checks in the mail. A check that goes astray can result in a missed payment that can knock 100 points or more off credit scores. Electronic payments are far more secure and efficient.
