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.

I respectfully disagree with point number three. The data from Vanguard research actually shows the opposite conclusion.

The math checks out but I think you are being a bit conservative with the return assumptions. Historical averages suggest higher.

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

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

Has anyone tried this with a single income household? We are a one-income family and wondering if the same principles apply.

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