ELI5: Why do credit scores start at 300 instead of zero?
gpt
FICO already developed a credit scoring system in the 1950s that ranged from 0-300. In 1989, they developed a more accurate system that was on a scale from 0 to 550 points. However, some banks still relied on the old system to determine credit worthiness. In order to stop any possible confusion, FICO decided to start the new credit scoring system at 300 points. That way whenever a bank looked at a credit score, they immediately knew which scoring system was being used.
