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

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

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

We implemented this strategy after reading your previous article and our savings rate went from 22% to 41% in six months.
