Upgrade payback
Cash purchase payback
Estimate how many rides it takes to earn back a Cash purchase. Type the price you are about to pay, the extra Cash one ride pays after the purchase, and how many minutes that ride takes. The result is arithmetic from your numbers. It is not an official payout.
Payback cycles = upgrade cost ÷ extra profit per cycle, rounded up.
Defaults are demonstration inputs, not a measured earn rate. 750 is the reported Cash price of the Ninerot F3 Pro on 14 October 2026. 100 extra Cash and 10 minutes are placeholders. Replace every number with your own ride. The game has not published a Cash-per-minute formula, and gamepasses that multiply Cash are not included unless you put their effect into the extra-Cash box.
