Your credit utilisation ratio is the second most powerful factor in your FICO score, right after payment history. It accounts for about 30% of your score, which is more than the length of your credit history, your mix of accounts, or any new credit you apply for. Quick note on spelling: utilisation (UK) and utilization (US) mean the same thing. We will use the US spelling utilization throughout the rest of this article.
If your score has been stuck or moving in the wrong direction, your utilization is usually the first place to look. The good news is that this is one of the fastest things you can change. A simple payment timing trick can move your score within 30 days.
What Is the Credit Utilization Ratio?
Your credit utilization ratio is the percentage of your total available credit that you are currently using. If you have a credit card with a $1,000 limit and a $300 balance, your utilization is 30%.
The formula is simple:
Credit Utilization = (Total Balances ÷ Total Credit Limits) x 100
Credit bureaus calculate this in two ways. Per-card utilization looks at each individual card. Overall utilization combines all your revolving accounts into one number. Both matter, but the overall ratio carries more weight in most scoring models.
Why Utilization Affects Your Score So Much
Lenders see high utilization as a warning sign. If you are using most of your available credit, it usually means you are stretched thin and at higher risk of missing payments. That is why a high ratio can drag your score down even if you pay every bill on time.
FICO and VantageScore both penalize utilization above 30%. Anything over 50% is considered high risk. Once you cross 70% to 80%, the damage to your score can be steep, sometimes 50 to 100 points. For a deeper look at the mechanics, see why higher credit utilization decreases your credit score.
The flip side is that lowering your utilization can give you one of the fastest score boosts in credit building.
What Is a Good Credit Utilization Ratio?
Most credit experts agree on these benchmarks:
- Excellent: 1% to 9%
- Good: 10% to 29%
- Fair: 30% to 49%
- Poor: 50% or higher
A common myth is that you should keep utilization at 0%. That is actually not ideal. A small balance, around 1% to 5%, tends to score better than 0% because it shows you are actively using credit responsibly.
For most people, aiming for under 10% on each card and overall is the sweet spot.
How to Calculate Your Credit Utilization
Grab your latest statements or log in to each credit card account. Write down your balance and credit limit for each card. Then:
- Add up all your balances.
- Add up all your credit limits.
- Divide total balances by total limits.
- Multiply by 100 to get the percentage.
Example: You have three cards with balances of $200, $500, and $100. Your limits are $1,000, $2,000, and $500. That is $800 total balances divided by $3,500 total limits, which equals 22.9% utilization.

Six Ways to Lower Your Credit Utilization Ratio
Here are the most effective strategies, ranked by speed:
Pay down balances before the statement closes. Credit bureaus see the balance reported on your statement date, not your due date. If you pay a week early, the lower balance gets reported, and your utilization drops the next month.
Make multiple payments per month. Instead of paying once, pay twice or three times. This keeps your reported balance low all month long.
Ask for a credit limit increase. If your limit goes up but your spending stays the same, your utilization automatically falls. Many issuers grant increases after six months of on-time payments.
Open a new credit-building card. Adding more available credit lowers your overall ratio. The Self Visa® Credit Card and Kikoff Secured Credit Card are easy starter options that report to all three bureaus.
Keep old cards open. Closing a card removes its limit from your total available credit, which spikes your ratio. Keep zero-balance cards open even if you don't use them.
Spread balances across cards. If one card is maxed out and another is empty, your per-card utilization is dragging you down. Move some debt over so no single card is above 30%.
Common Credit Utilization Mistakes
A few habits will keep your utilization stubbornly high:
- Carrying a balance on purpose to build credit (you don't need to)
- Paying only the minimum each month
- Closing your oldest card after paying it off
- Forgetting that store cards count too
- Ignoring authorized user accounts that show on your report
Using budgeting tools like Brigit can help you spot when spending is creeping up before it hits your statement.
How Fast Does Lowering Utilization Help Your Score?
Credit utilization has no memory. Unlike late payments, which stay on your report for seven years, utilization only reflects your most recent statement. That means as soon as a lower balance is reported, your score can jump.
Most people see a score change within 30 to 45 days of paying down balances. People who go from 70% utilization to under 10% often see jumps of 40 to 100 points in a single billing cycle. The exact amount depends on the rest of your credit utilization profile.

Frequently Asked Questions
Does paying off my credit card every month reduce my utilization?
It depends on timing. If you pay before your statement closes, your reported utilization is lower. If you pay after the statement closes but before the due date, the higher balance is what gets reported to the bureaus, even though you didn't carry interest.
Will my utilization drop if I get a credit limit increase?
Yes. A higher limit with the same balance automatically lowers your utilization ratio. This is one of the fastest ways to improve your score without changing your spending habits. Just be careful not to spend more once the limit goes up.
Does utilization on store cards count?
Yes. Any revolving credit account, including retail store cards, counts toward your overall utilization. Even a small balance on a department store card can drag your ratio higher if you don't track it.
What's the difference between credit utilisation and credit utilization?
They are the same thing. Utilisation is the British spelling and utilization is the American spelling. Both refer to the percentage of available credit you are currently using, and both are calculated the same way.
