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

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

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