Utilization is how much of your card limit you're using, and it's one of the fastest-moving parts of your score. The trick most people miss: your balance is reported to the bureaus on your statement closing date, not your due date. So you can pay in full every month and still look maxed out — if a big balance was sitting there on the day the statement closed.
Walk through it. Say you have one card with a $500 limit.
- You charge $300 during the month (that's 60% of the limit).
- You pay it off after the due date, like always. But the statement already closed with $300 on it — so the bureaus saw 60% utilization. High.
- Now flip the timing: you pay it down to, say, $25 before the statement closes. The statement reports a $25 balance — 5% utilization. Same spending, much better number, just from timing the payment.
That's the whole move: pay down before the statement closes, not just before the due date. Aim to keep each card — and your overall use — under about 10%.
AZEO ("All Zero Except One") is the tidy version when you have several cards: pay every card to $0 before it closes except one, which you let report a small balance (a few percent of its limit). Reporting one tiny balance, with the rest at zero, is a clean pattern for scoring models. Find each card's closing date (it's on the statement), and set a reminder a few days before to pay down.
