Credit utilization mastery
Keep total and per-card utilization under 10% to maximize points.
The utilization ladder
| Reported utilization | Score impact |
|---|---|
| 0% | Slightly negative (looks inactive) |
| 1-9% | Optimal — peak points |
| 10-29% | Good |
| 30-49% | Noticeable drag |
| 50-74% | Significant damage |
| 75%+ | Severe damage, near-max effect |
The two utilization numbers that matter
- Per-card utilization — each card's balance ÷ that card's limit
- Aggregate utilization — total balances ÷ total limits across all cards
You need both under 10% to maximize points. A single card at 90% will tank you even if your aggregate is 8%.
The statement-date trick
Your card issuer reports your balance to the bureaus on your statement closing date, not your due date. Pay the balance down to ~1% before the statement closes and the bureau will see the low number.
Statement closes: 15th → pay by the 14th
Due date: 5th of next month → already covered
The "AZEO" method (All Zero Except One)
Pay every card to $0 except one, which carries 1-9%. This is what people on 800+ club do the month before a mortgage application.
