But when he first began using credit, he made what he now considers his biggest credit mistake: only using one credit card with a low limit.
How credit scores are calculatedAfter he began working in the credit industry, Ulzheimer learned how FICO credit scores are calculated and realized his mistake.
"Instead of trying to depend on one credit card, I learned how to properly manage a whole inventory of credit cards," he says.
Having more credit cards increased his overall credit limit and improved his credit utilization rate.
As soon as he spent above $60 on his initial credit card with a $600 limit, it bumped his credit utilization rate above 10%.
