This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own Shoot For Eggs session. It will not click the shop.
Upgrade payback
Cash purchase payback
Estimate how many of your own income cycles it takes to earn back a gun, plot upgrade, or other cash purchase. Replace every default with the number in your server.
Payback cycles = upgrade cost ÷ extra profit per cycle, rounded up.
Example only. 18000 is one observed Crossbow price, not the live shop price. Enter the price on your gun shop and the extra cash per cycle you think the purchase adds. The result is payback cycles from those inputs. It does not read your plot, your Damage stat, or a hidden game formula.
