Subtracting the 108,532 that seems to have been recorded before I truly came back to the game about 7.25 years ago, I've averaged 16,226.65/day, or about 486.8k/month. I would consider it completely unhealthy as an average, though, and would not recommend it to people I cared about. I think your amount is within reason, OP, and could be much worse (in the lower sense) too.
Activity alone isn't as important as making efficient use of your online time. The essentials can be done relatively quickly; relative to somebody who goes all out, you can generally get 80% of the benefits in 10% of the time. I would aspire more to do that in general, and to be making the best of the extra time you do invest in the game. You'll want to focus on some other metrics to see how you've done with that.
