Most people are told "keep it under 30%." That’s not wrong, but 30% is a ceiling, not the goal — we teach keeping it under 10% on each card and overall. Here’s how the number actually works.
What credit utilization is
Utilization = your reported balance ÷ your credit limit, as a percentage.
- A card with a $300 balance and a $1,000 limit = 30% utilization.
- It’s scored two ways that both matter: per card (each individual card) and overall (all balances ÷ all limits). Maxing out one card can hurt you even if your total looks low.

Utilization is an important part of the "amounts owed" category — about 30% of a FICO score in FICO’s published weights — so after paying on time, this is the biggest lever you control, and unlike payment history you can change it in a single billing cycle. (New to all this? What Credit Actually Is — or see where utilization sits among the five score factors.)
How is credit utilization calculated?
Credit utilization = (total balances ÷ total credit limits) × 100.
The × 100 is the step that turns the ratio into the percentage everyone quotes. Worked through two cards:
| Card | Balance | Limit | Per-card utilization |
|---|---|---|---|
| Card 1 | $300 | $1,000 | 30% |
| Card 2 | $450 | $2,000 | 22.5% |
| Overall | $750 | $3,000 | 25% |
$750 ÷ $3,000 = 0.25, and 0.25 × 100 = 25%. Both numbers get scored — the 25% overall and each card on its own — which is why Card 1 sitting at 30% still counts even though the combined figure looks fine.
The target we teach (it’s not 30%)
"Under 30%" is a common rule of thumb, not the target. The target we teach is under 10% on each card and overall. FICO publishes no utilization zones and no point values for them. Experian (December 12, 2025) says people with the best scores tend to keep utilization below 10% and that 0% gives no extra benefit; myFICO says that in some cases a low ratio helps more than not using any of your available credit at all. Neither names a dollar amount to leave on a card, so use your cards, pay in full, and never carry a balance to help your score.
So the goal isn’t "use less than a third of your limit" — it’s "keep the reported balance under 10% on each card and overall."
The timing trick that lowers it fast
Here’s the timing: your issuer usually reports your balance to the bureaus on your statement closing date — not your due date (which is ~3 weeks later). Whatever balance shows when the statement closes is usually what hits your credit report. So even if you pay in full every month, a big balance can still be reported if the statement closes mid-spend. The move:
- Pay your balance down to a small amount a few days before your statement closing date (find that date on your statement or by asking the issuer).
- Then pay the rest by the due date as normal to avoid interest.
This one habit can drop your reported utilization without spending a dollar less. (How balances land on your report: Credit Reports Decoded.)
Faster ways to lower utilization
- Pay down your most-maxed card first. Because per-card utilization matters, taking one card from 90% to 10% means your report no longer shows a nearly maxed-out card — spreading the same payment across several already-low cards doesn’t do that.
- Ask for a credit-limit increase. Ask your issuer to raise your limit — and ask whether they can do it without a hard inquiry (some issuers offer a soft-pull option with no score impact; others run a hard pull, so ask first). A higher limit means lower utilization even if your spending never changes — an easy win.
- Don’t close old cards. Closing a card removes its limit from your total, which can spike your utilization. Keep no-annual-fee cards open. (Score dropped out of nowhere? Your Score Dropped — the 8-Reason Checklist.)
It has no memory — which is good news
Standard FICO models (like FICO 8) only look at your most recently reported balance, not your history. If you ran a card at 85% last month and pay it to 4% this month, the old high balance stops counting once the lower number reports — though no one can promise how much your score will move or when. (One exception: newer "trended" models like FICO 10T look at about 24 months of balances, so consistently low utilization is best for the long run.)
The bottom line: you control your reported balance, but no one can promise how much your score will move or when. Keep reported balances under 10% on each card and overall, and pay before the statement closes. (Just starting out? How to Build Credit From Scratch.)
