This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own Steal an Egg for Squishy Dumplings! session. It will not click the shop.
Upgrade payback
Upgrade payback
Estimate how many cycles a treadmill or plot purchase needs before it pays for itself. You type the cost and the extra cash. The form does not know live shop prices.
Payback cycles = upgrade cost ÷ extra profit per cycle, rounded up.
The default 1000 and 50 are blank examples so the form is not empty. They are not prices from Steal an Egg for Squishy Dumplings. Replace them with the cash cost on your treadmill or plot board and the extra income you measured after a similar buy. Leave extra income at 0 only when you have not measured a gain yet.
