Upgrade payback
Upgrade payback
Estimate how long an income upgrade takes to pay for itself from numbers you type in. Use it when a card only adds Energy or cash. Do not use it for unlocks, resets, or Eternal Shard sinks.
Payback cycles = upgrade cost ÷ extra profit per cycle, rounded up.
Type the cost shown on the upgrade and the extra income you expect each cycle after buying it. The result is how many cycles, and about how many minutes, until that extra income covers the cost. It does not read a save, and Regrowth Incremental has not published an official payback formula. Ignore the result if the upgrade unlocks a new board instead of adding income.
