I heard that using more than 15% of my credit line is bad. Can you please explain why though?

• credit card rates
• credit card apply
• best credit card to apply for
• credit report score
• your credit score
• stop limit order
• calculate percentage salary increase

Or is it 15%, or 30%, or 20%?


I've heard so many different opinions that I'm confused as to which percentage I should not go over.


Please tell me which is the correct percentage and WHY it's bad to go over it.


Thank you guys.
