This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own [π] Clean the Moon! session. It will not click the shop.
Upgrade payback
Upgrade payback
Estimate how many sell trips it takes to earn back an upgrade using the price on your own board. Defaults are examples, not live prices.
Payback cycles = upgrade cost Γ· extra profit per cycle, rounded up.
Replace every number. A public playthrough once showed a Backpack upgrade at $1.00 and an early sell prompt of GET $0.50. Those are single-screen examples, not the extra profit of an upgrade and not a price that stays fixed. The calculator does not read your Roblox account.
