Meh, looks nice and UX is OK, but not really useful IMO.<p>Often, growth means that operating cost also grow, e.g., due to higher infrastructure cost, more worker salaries, expansion into more economic markets with more/new regulations to tackle, ....<p>That could be at some fixed percentage in a simple model, and is a quite relevant factor which this tool completely misses.<p>So go for that spreadsheet, it can start really simple, with minimal parameters like this has - but being able to adapt and expand it over time as ones business growths and changes allows for much better and more efficient planning.

Looks cool, but keeps freezing for me on Safari 14.1.<p>After dragging any of the sliders for a bit, the console reports:<p>```
SecurityError: Attempt to use history.replaceState() more than 100 times per 30 seconds
```<p>and it freezes.
