Three years ago, I introduced you to ProjectionLab and called it the most powerful financial planning tool I’d ever seen. It was built specifically for people pursuing FIRE, and it’s still the most useful FI planning tool I’ve found. In the original post , Kyle (the solo developer behind the project) shared his background and walked through how to build a plan. When I built my first plan, I realized I needed to immediately change my investment strategy (I stopped contributing to my tax-deferred accounts because the software showed me that I already contributed too much to those accounts). Since then, I’ve watched Kyle quit his day job, grow a team, and turn ProjectionLab into something even more impressive. The tool has changed a lot recently, and I wanted to invite him back to share what’s new. Because after using the new features, I’ve changed my financial plans yet again!…
