Have you made mistakes regarding your credit in the past? That could haunt you ... for a long time.
A whopping 68 percent of Americans make at least one major financial mistake, or "credit fumble," before turning 30, leading to a negative mark on their credit report, according to a Credit Karma survey.
These mistakes include overspending on credit cards, missing payments, defaulting on a loan or having an account sent into collections, the survey found.
The greater the offense, the longer it will reflect on your credit report, said Bethy Hardeman, chief consumer advocate at Credit Karma. In fact, it usually takes consumers seven to 10 years to erase negative marks from their credit, thanks to the Fair Credit Reporting Act.
"I think what a lot of people don't realize ... is how a missed payment can stay on your credit," Hardeman said. "It can be one mistake that you don't think is a big deal that can cost you thousands in the long run."
