No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
I'm confused by your post. Your balance divided by your limit IS your utilization......
ie: Balance 200, Credit Limit 1000
200/1000=.20 or 20%
CreditKeeper.com lists overall utilization fro $9.99 per month and the reports are accurate. The scores are FAKOS.
Remember you can have an overall utilization of less than 30%, but having any one card over 10% utilization lowers your score.
Best Wishes.
