I created a sheet for myself to wrap my head around the different investment options. Here you can see your total investment for the options you choose to check as owned, the ROI for each tier (not the whole block together). All stocks are included, even the passive ones. I have chosen not to evaluate ROI for stocks not paying out sellable things (MSC/EVL/BAG). Feel free to make your own copy of the sheet to play around with.
Big thanks to Jotero for helping with the sheet.
Edit: ASS and MUN added to the sheet
Edit: API calls for stocks now added and updates hourly. Added a TCI eval for a variation of merits, length of investment and size of investment. The TCI RoI is now dependant on the values you feed in regarding merits, investment etc. Item dividend value is now automatically updated from Torn market hourly. Bank interest rate is automatically updated daily.
