Best budgeting software recommendations?

Does anyone know of a specific software for calculating things like gear ratios or shaft specs?
I absolutely loathe building these spreadsheets manually in Excel—and while I know it’s possible, I’ve realized I can do it—😍but honestly, typing out every single calculation is just tedious work. Can anyone point me toward a tool that might handle this? 🙂

Thanks in advance! 🙂

The software can be fully customized to align with your specific requirements.
Please feel free to reach out if this sounds like something you might be interested in pursuing.

I was thinking this might be useful for you guys...

Can someone please walk me through how this software actually works? I need help.

Maybe take a quick look through the documentation here: http://www.mitcalc.com/doc/help/en/index.htm--it might actually save you some headaches later on.
