No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
Yes and no.
Your score is based on utilization overall and on each card, so if you rack up $400 on your QS card you're still only at 10% overall, but at 80% on that one card, which will hurt your score. Your score for overall utilization will be OK in that scenario, but you'll take a hit for high utilization on the one card. I figured this out the hard way...
Also keep in mind the bigger your profile the lesser the sting from UTI.
If you have $2000 in CCs and let $1800 report... the FICO store will take a serious hit.
If you have $75000 in CCs and let $5000 report... the hit will be much less.
I have $60k+ and let $5k report on my Sallie Mae a few months ago and lost 3 points on EQ... I paid the bill off and the next month's new balance was $1300... got all 3 points back.
Unless you are planning a house or car purchase in the next 30 days playing the UTI game isn't necessary... FICO has no month to month UTI memory so if you lose a point here or a point there for carrying a balance you'll get the points back when you pay the bill and the paid down balance reports.
