Turn the income and cost you observe in-game into cash/min, cash/hour, and payback time for a new fisherman or upgrade.

Enter the numbers you observe in your own game — income per fisherman, how many you run, and what the next purchase costs and adds. The calculator turns them into cash/hour and payback time.

What one fisherman earns per minute.
How many are on your docks right now.
The cash you would spend.
How much the new fisherman/upgrade adds per minute.

How to use

  1. Enter the income per fisherman you observe (cash per minute).
  2. Enter how many fishermen you run and the cost of the next purchase/upgrade.
  3. Enter the extra income the new fisherman adds, then read cash/hour and payback time.

Examples

Good upgrade

A 2,000-cash fisherman that adds 25 cash/min pays for itself in 80 minutes — worth it for a long session.

Bad upgrade

A 50,000-cash upgrade that only adds 10 cash/min takes ~83 hours to pay back — skip it until it is discounted.
