In order to keep track of my assets, my savings rate, my FIRE date, I rely a lot on tools. Most of these tools are xls based. As i have learned a lot from the tools of others and the insights that other give on their blog, I wanted to return the favor. I will therefore keep here a list of the tools that I use.
This tool allows you to estimate the number of years that you need to reach FI. The tools assumes that you are happy with a given Save Withdrawl Rate. This rate is customizable in the tool.
Next to that, the tool will force you to think about your future spending and savings. This means that you need to have a fairly good idea on what you earn and spend per year. You can enter the same value for each year. I recommend to really spend some time on thinking about these numbers. That way, you will get better results
Please note that I make these tools for fun only. These tools have no formal value other than entertainment for me. For an in depth analysis, plan an appointment with a certified financial planner.
