What is a good credit utilization ratio?

Below 30% is the standard recommendation, but below 10% produces the best credit scores. People with 800+ credit scores typically use less than 7% of their available credit.

How is credit utilization calculated?

Divide your total credit card balances by your total credit limits. If you have $2,000 in balances and $10,000 in total limits, your utilization is 20%. Both per-card and overall utilization matter.

How quickly does credit utilization affect your score?

Credit utilization updates every billing cycle (monthly). Paying down a balance can improve your score within 30 days. Unlike late payments, high utilization has no lasting damage once reduced.

Credit Utilization Ratio: What It Is and Why It Matters (2026)

Credit utilization—the percentage of your available credit you’re using—is the second-most important factor in your credit score at 30%. Here’s exactly how it works and how to optimize it.

What Is Credit Utilization?

Credit utilization = (Total credit card balances ÷ Total credit limits) × 100

Example

Card	Balance	Limit	Utilization
Card A	$500	$5,000	10%
Card B	$1,200	$3,000	40%
Card C	$0	$7,000	0%
Total	$1,700	$15,000	11.3%

Both overall utilization (11.3%) and per-card utilization (Card B at 40%) affect your score.

Credit Score Impact by Utilization Level

Utilization Range	Score Impact	Who’s in This Group
0%	Slightly negative (shows inactivity)	Not ideal—use cards lightly
1-9%	Best scores	People with 800+ scores average ~7%
10-29%	Good	Standard recommended range
30-49%	Moderate negative impact	Score starts dropping noticeably
50-74%	Significant negative impact	Major score reduction
75-100%	Severe negative impact	Can drop score 50-100+ points
100%+	Worst impact	Maxed out—major red flag to lenders

Utilization vs. Credit Score (Approximate Impact)

Utilization	Approximate Score Effect*
5%	+0 (baseline—optimal)
10%	-5 points
20%	-15 points
30%	-25 points
50%	-45 points
75%	-75 points
100%	-100+ points

*Approximate. Actual impact depends on other credit factors.

How to Lower Your Credit Utilization

Quick Fixes (Same Billing Cycle)

Strategy	How It Works	Speed
Pay before statement closes	Reduces reported balance	Instant (next reporting)
Make multiple payments per month	Keeps balance low at all times	Ongoing
Request a credit limit increase	Higher limit = lower ratio	1-3 days

Long-Term Strategies

Strategy	How It Works	Timeline
Open a new card	More total available credit	1-4 weeks
Don’t close old cards	Preserves available credit	Ongoing
Pay down balances aggressively	Reduces numerator	Weeks to months
Become an authorized user	Adds another card’s limit to your profile	1-2 billing cycles

Common Myths About Credit Utilization

Myth	Reality
“You should carry a small balance”	No. Pay in full. Utilization is based on statement balance, not carried balance.
“0% utilization is best”	Not quite. 1-5% is slightly better than 0%, which can look like inactivity.
“Only overall utilization matters”	Per-card utilization matters too. One maxed card hurts even if overall is low.
“High utilization permanently damages your score”	No. Unlike late payments (7 years), utilization resets every month.
“Utilization from debit cards counts”	No. Only revolving credit (credit cards, lines of credit) is counted.

The Bottom Line

Keep your credit utilization below 30%—and below 10% if you’re optimizing for the best credit score. The easiest way is to pay your balance before your statement closes or request a credit limit increase. Unlike late payments, high utilization has no lasting impact: lower it and your score recovers within a month.
