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

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?

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