Building Good Credit
Step-by-step credit building for beginners, thin files, and rebuilders — the five FICO factors and how to move each one.
The five FICO factors
Payment history (35%), amounts owed (30%), length of credit history (15%), credit mix (10%), new credit (10%). Payment history and utilization are the levers you can move fastest.
Utilization targets
Aggregate utilization under 30% is 'okay,' under 10% is optimal. Report a $0 balance on one card, and a small balance on another for the strongest scoring signal.
Frequently asked questions
Does closing a card hurt my credit?
Usually yes. Closing an old card lowers your average age of accounts and reduces total available credit, raising utilization.
