what credit score number is excellent vs good

A+ (Excellent) would be anything higher than 740. A 720 - 740 would be A (Very Good), with a 700 - 720 (B+) Good. Moving on, you would find a 680 - 700 as B (OK), and a 640 to 680 about a C+ (Weak). Below that, you would hit maybe the 620 to 640 as a C (Poor), a 580 - 620 Maybe a D (Bad), and below a 580 as an F (Horrible).
