Those computer levels can't be rated because they don't play timed games and because they allow takebacks.
They also run on your device, not on chess.com servers so its capabilities matter a lot.
Your rating is based on your play against humans. Your current rapid rating of 685 and blitz rating of 371 suggests that you can beat the computer set at level 1and 2. Is that right?
If you can beat level 4, you can't go around and legitimately claim to be a 1250.
Hello fellow Chess.com players! I have found the ratings of the Chess.com computer levels. On my iPhone, playing on the Chess.com app I can play against the computer as well. There are 20 levels of computer difficulty on the app for iPhone and beside each level is a rating in parentheses. So by taking level 20 on the iPhone as level 10 on the PC, level 10 on the iPhone as level 5 on the PC and level 2 on the iPhone as level 1 on the PC I have come up with the ratings for the Chess.com computer on the PC.
For PC:
Level 1 - 350
Level 2 - 650
Level 3 - 950
Level 4 - 1250
Level 5 - 1550
Level 6 - 1850
Level 7 - 2150
Level 8 - 2450
Level 9 - 2750
Level 10 - 3000+
Have fun playing!
