Frequently Asked Questions
What is credit utilization?
It's how much of your available credit you're using, shown as a percentage — total balances divided by total credit limits. It's one of the bigger factors in most credit scoring models.
What's a good utilization ratio?
Many guidelines suggest staying under 30% overall, with under 10% considered ideal for the best scores. Lower is generally better.
Does per-card utilization matter, or just the overall number?
Both can matter. Some scoring models flag a single card that's maxed out even if your overall utilization looks fine, so it's worth checking your highest individual card too.
How can I lower my utilization quickly?
Paying down balances is the most direct way. Requesting a credit limit increase can also lower the ratio, though it doesn't reduce what you owe.
Is this financial advice?
No — this is an estimate for planning purposes only, not financial advice.
