A credit score of 670 is considered average as of 2014, according to Melissa Ezarik for Bankrate. Although classifications of credit scores change over the years, a score of 720 to 850 is ideal. Credit scores range from 300 to 850 and can vary based on debt and spending activity.
Lenders use credit scores to make lending decisions, and each lender typically has its own strategy and opinion regarding what constitutes a good credit score, which is the global standard for evaluating credit risk. Additional factors, such as debt, on-time payments and the ratio of credit card balances compared to credit card limits, also affect a credit score, explains the Fair Isaac Corporation on myFico.com.
