Frugal living does not mean deprivation. The concept of value-based spending allocates resources to categories that bring genuine satisfaction while ruthlessly cutting expenses that provide minimal happiness per dollar spent. For more on this topic, see Side Hustle Income.

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

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

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

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

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

My financial advisor recommended the exact same approach. Nice to see it validated with actual numbers.
