But a good estimate will be around 6+k to 7k gross monthly, with all the bonuses, should be near 100k like what the other poster has mentioned.

Good performers should reach this 6+k in their 7th year or so. And by 10th year, depending on whether they have positions, they should at least reach GEO5 and probably even near the ceiling.
