Upgrade payback
Boat Upgrade Payback
Estimate how many cycles a boat or pen purchase needs before the extra pet cash covers its price. Type the cost from your own menu and the extra cash you expect over a cycle you choose.
Payback cycles = upgrade cost ÷ extra profit per cycle, rounded up.
The defaults are a worked example, not a live boat stat. 1,000 is the first ship upgrade price seen in recorded play. 60 extra cash per 1-minute cycle is what an extra $1 per second would add. Replace every field with the price on your upgrade station and the income change you can actually read. The form does not know your boat, your pen, or future hatch results.
