Scenario tool
When would an upgrade pay back?
Enter a cost and your current and proposed effective income per second. The result is only a cash payback scenario—it does not price speed, convenience, Robux, or unknown game effects.
Formula
incremental rate = proposed rate − current rate, then payback seconds = cost ÷ incremental rate. Cost and income must use the same in-game currency. A zero or negative improvement has no positive cash payback.
Build the two scenarios first in the tank planner.
