I'm not sure I've seen an official statement anywhere on the levels, but I go by this bar graph that we have in the Turbo apps:
My credit score bar graph
What I've learned over the past year and a bit working on Turbo:
- below 600 is poor,
- 600-650 is ok,
- 650-700 is better
- 700-750 is pretty good, and
- 750 and above is really good, and above 800 amazing. All totally my words of course
I feel like anything above 700 is pretty good these days. Turbo does have a neat feature where we show the average credit score for someone your aged, and mine says 719.
Hope that helps a little.
