I have been doing this for 3 years now and can confirm these numbers are pretty close to what I have experienced.

Can you do a follow-up article about how this applies to people with variable income? Like freelancers and consultants?

Bookmarked this. Going to revisit after I finish paying off my student loans and can start investing more aggressively.

This is a bit misleading. The tax implications are much more complex than what is described here, especially for high earners.

Great article! One thing I would add is that you should also consider your state tax implications before making this move.

This is exactly what I needed to hear. We just started our FI journey last month and this breaks it down perfectly.
