Frequently asked questions

Why does utilization matter?
It's ~30% of your FICO score. Low utilization = responsible usage = higher score. 0% is suboptimal too; 1–10% signals active but controlled use.
Per-card or overall?
Both matter. Overall is weighted more, but having one card at 100% + others at 0% hurts more than spreading evenly.
Should I close unused cards to simplify?
No — closing reduces total limit, which increases utilization on remaining balances. Keep old accounts open unless there's an annual fee.
When does utilization report?
On statement close date. To minimise reported utilization, pay balance down BEFORE statement closes, not before due date.
