A good Fair Isaac Corporation (FICO) credit score is within the 690 to 720 range, according to Nerd Wallet. FICO credit scores range from 300 to 850, with anything under 630 generally considered to be poor.
A FICO credit score is determined by five separate components, according to Nerd Wallet. Making all payments on time accounts for 35 percent of the score, and even one late payment can significantly lower your credit score. The amount of credit used is 30 percent, the length of credit history is 15 percent, the amount of new credit applications is 10 percent and the kind of credit used accounts for 10 percent of the total FICO score.
