Question of the Day: How Long Will It Take a Teen to Get a Credit Score?

Answer:  6 months, according to FICO.

From GoBankingRates:

Teens will have a credit score as soon they keep one credit account open for about six months, according to FICO. Though they might not realize it, the credit history teenagers start to develop will have a huge impact on their lives, from the interest rate they receive on their first auto loan to the kind of credit card they can obtain in college. Because of this, parents need to make sure their children are well-informed about the benefits and pitfalls of managing credit, and how to build a great credit score.
