Q&A: Account closure and credit scores

June 21, 2021 By Liz Weston

Dear Liz: My mother is very focused on her credit score, which is consistently excellent. I found out that she recently called her bank and asked it to lower her credit limit on one of her long-held credit cards from $32,000 to $5,000. She uses the card only to charge infrequent, small amounts and always pays it off. She believes having a large credit limit counts as “potential debt” and hurts her credit profile, whereas I believe having a high credit limit on a lightly used card is very good for your credit. I guess we’ll find out who’s right next month when my mom diligently checks her credit score. In the meantime, could you weigh in?

Answer: You are correct. Credit scoring formulas like to see a big gap between the amount of credit you’re using and the credit you have available. Lowering your credit limit on a card can have a negative effect on your scores.

Before the advent of credit scoring, lenders did worry that someone with a lot of available credit would suddenly run up big balances and default. Data scientists discovered, however, that people who had been responsible enough to be granted high limits tended to remain responsible with their credit.

If your mother has several other credit cards and uses this one lightly, the effect may not be significant. If she wants to keep her scores high, however, she probably shouldn’t repeat the experiment with any other cards.
