Upgrade payback
Upgrade payback
Estimate how many income cycles a coin upgrade needs before it earns its cost back. Type the price you see and the extra coins that upgrade adds each payout. The form does not read your match.
Payback cycles = upgrade cost Γ· extra profit per cycle, rounded up.
Demo defaults are round examples, not a hidden game formula. Replace them with the upgrade price and the extra coins you actually see. One play report described an upgraded Money Printer paying about 300 coins every 5 seconds, and lobby upgrade examples included about 250 coins for an early Cannon, about 6,000 for a Mining Cave, and about 17,000 for a higher Farm tier. Those figures are observations, not a price list.
