5 credit utilization myths that are hurting your score right now

Keep credit utilization below 30%, but under 10% is ideal. Closing a card hurts utilization because it reduces available credit. Utilization resets monthly — it has no long-term memory.

Credit utilization, the percentage of your available credit you’re currently using, is the second most important factor in your FICO score, right behind payment history. If you have a $10,000 limit and a $3,000 balance, your utilization is 30%. Simple math, but most of what people believe about it is wrong. Let’s clear that up.

Why utilization matters so much

Utilization signals to lenders how reliant you are on borrowed money. High utilization suggests financial stress, even if you’re managing payments fine. It accounts for roughly 30% of your FICO score, which means getting it wrong can cost you hundreds of points over time.

Myth 1: “Keep it under 30% and you’re fine”

Reality: The 30% “rule” is a ceiling, not a target. People with the highest credit scores (800+) typically keep utilization under 7%. The sweet spot for most scoring models is 1-9% — just enough to show you’re actively using credit, but not leaning on it.

What to do: Aim for single-digit utilization if you’re optimizing for score. Under 30% is acceptable, not ideal.

Myth 2: “High utilization permanently damages your score”

Reality: Utilization has zero long-term memory. Unlike late payments (which haunt your report for 7 years), utilization is recalculated fresh each billing cycle. If your utilization spikes to 80% this month but drops to 5% next month, your score rebounds fully.

What to do: Don’t panic over a temporarily high month. Just pay it down before your next statement closes.

Myth 3: “Closing old credit cards helps”

Reality: Closing cards hurts your utilization ratio. When you close a card, you lose that credit limit. Your total available credit drops, which pushes your utilization up even if your balances don’t change.

Example

• Before closing: $3,000 balance / $20,000 limit = 15%
• After closing a $5,000 limit card: $3,000 / $15,000 = 20%

What to do: Keep old cards open, even if you rarely use them. Put a small recurring charge on them to prevent the issuer from closing them for inactivity.

Myth 4: “Only your total utilization matters”

Reality: Both overall and per-card utilization affect your score. Even if your total utilization is low, having one card maxed out sends a negative signal. Scoring models look at individual card ratios too.

What to do: Spread balances across cards when possible. Don’t let any single card exceed 30%.

Myth 5: “You should carry a balance to build credit”

Reality: This is the most expensive myth in personal finance. You do not need to carry a balance or pay interest to build credit. Paying your statement in full every month counts as credit usage and gets reported to bureaus, minus the interest charges.

What to do: Pay in full every month if you can. Your wallet will thank you.
