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

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

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