Wow! … Just wow!
First off, @bdunks, thanks for taking the initiative to port this popular template to Excel.
Second, I’m really impressed with the fidelity to the Sheets version. Not only the UX, but I added test data and it all lined up to the decimal point to values output from the Sheets version.
Finally, you’ve done a great job with the build quality, using spill ranges and LAMBDA functions throughout the calculations. The interoperablity with your Cash Flow Forecast](Cash Flow Forecast (Excel)) is also welcome and well done.
I’ve got one really small change request for you… could you change the Learn & Discuss link to point to https://community.tillerhq.com/tag/tcs-retirement?
If you’re familiar with the Tiller Builder Rewards Program , you know that we award a sliding scale of cash prizes based on:
- Value of concept to the personal-finance community
- Value & quality of Tiller integration
- Uniqueness of concept vision
- User experience & usability
As the Community’s first long-term planning template available in Excel, this solution with its create build quality is a homerun 
and we are excited to award you $750 for building and documenting this Retirement Planner template-port to Excel.
Thank you @bdunks!
P.S. You might notice a similarly effusive award and recognition in the thread for your Cash Flow Forecast port for Excel.
