This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own Build a Base & Steal Plants π± [CO-OP] session. It will not click the shop.
Upgrade payback
Upgrade payback estimator
Estimate how many earning cycles a cash purchase needs before the extra cash you type in covers its cost. Use your own income. The sample numbers are not official rates.
Payback cycles = upgrade cost Γ· extra profit per cycle, rounded up.
Replace every default before you trust the result. 50000 is one observed base-expansion price, not a published shop price. 25 minutes is one newly placed tree's remaining grow timer, used only as a cycle example. 1000 extra cash is a blank you must overwrite: plant income is not published. The form divides upgrade cost by extra cash per cycle, then multiplies cycles by the minutes you enter. It does not read your plot.
