Here is my retirement estimate for January 2019, based on December’s (2018) progress. First update of the new year! I’m hoping that this will be a big year of saving for me and also lead to some steady progress in the early retirement calculations too.
A reminder of the three ways I will tracking my progress:
- The first way will actually be with a simple excel calculator that I made. I’ll plug in my current monthly expenses, savings rate, and net worth. And the calculator will say just how long I have until retirement. Maybe it will say that I can retire tomorrow?
- The second way I’ll be calculating this is through an equation and the help of Wolfram Alpha.
- The third and final way I’ll be calculating my early retirement date is with the help of Mad Fientist Laboratory. I’ll input expenses, savings, and net worth and let his calculations do the rest of the work.

Retirement estimation based on 7% market growth:

Another bad month in the market leads to big decreases in both my IRAs, so of course, there is an uptick here. Even though I kept my savings pretty much flat for the month, it was just too much of a dip to overcome.
Retirement estimation if I never save another dollar:

Staying about the same here too, around 37 years with a slight increase. This calculation is strictly based on my net worth so it will look the worst when the market is going down.
