Upgrade payback
Studio button payback
Estimates how many sales cover one green-button cost. Type the Cash cost from the button and the extra Cash you expect on each later sale. The sample numbers are not in-game prices, and the form does not read your studio.
Payback cycles = upgrade cost Γ· extra profit per cycle, rounded up.
The sample defaults are round placeholders so the form is not blank. Replace them with the Cash cost printed on the green button and the offer change you actually see. This arithmetic does not know your Prestige multiplier, the five-minute auction lock, Stars, or the Cash you may need to hold for the Prestige menu.
