How does this calculator work?
Credit utilization = (balance ÷ limit) × 100. Below 30% is good for your credit score; below 10% is excellent. It accounts for about 30% of a FICO score. Pay down balances before your statement closing date to lower the ratio reported to credit bureaus.
Formula
How this is calculated
Credit utilization is the second most influential factor in most credit-score models, accounting for roughly 30% of a FICO score. It measures what fraction of your total revolving credit (credit cards and lines of credit) you are currently using. A lower ratio signals responsible borrowing and reduces lender risk — generally anything at or below 30% is considered good, and below 10% is ideal.
The ratio is calculated simply by dividing your current balances by your total credit limit and multiplying by 100. If you carry a $1,500 balance on a $5,000 limit, your utilization is 30%. Credit bureaus typically receive balance data from card issuers once a month (usually on the statement closing date), so paying your balance down before that date lowers the reported ratio even if you use the card heavily during the month.
For the best score impact, aim to keep individual card utilization as well as the overall aggregate below 30%. Maxing out even one card can hurt your score significantly, even if the rest of your cards are unused. Opening new cards raises your total limit and can lower the ratio, but only do so deliberately — each application causes a hard inquiry that can temporarily ding your score.
Frequently asked questions
Yes, but timing matters. Credit bureaus typically receive balance data on your statement closing date, not your payment due date. Paying before the statement closes — or making multiple payments during the month — reduces the balance reported to bureaus and lowers your utilization.
FICO and most scoring models look at both per-card utilization and aggregate (all-cards) utilization. Add balances and limits for every open revolving account — even unused ones — to get the most accurate picture of your overall ratio.
Below 30% is widely recommended for a good credit score, and below 10% is ideal if you are trying to maximise your score before a major loan application. There is no fixed rule — what matters is the trend and that you are not consistently near your limit.
