Credit utilization

The short answer

How much of your limit you’re using. It’s about 30% of a FICO score. The CFPB’s advice: keep it under 30%; lower is better.

Your card usually reports your statement balance, so pay most of it down before the statement closes and the bureaus see a small number.

Closing a card removes its limit: a $600 balance on $6,000 of limits is 10%; close a $3,000 card and it’s 20%.
