Input
Fish sold per loop
Meaning
How many fish you actually scale and feed each cycle
How to estimate
Use your normal batch size, not maximum inventory.

What each input means
| Input | Meaning | How to estimate |
|---|---|---|
| Fish sold per loop | How many fish you actually scale and feed each cycle | Use your normal batch size, not maximum inventory. |
| Average cash per fish | Rough payout after scaling | Estimate from recent sells and adjust after upgrades. |
| Minutes per loop | Catch, scale, feed, and return time | Include walking and scaling delay. |
| Next upgrade cost | The purchase you are planning | Try rod and knife costs separately. |

How to read the result
| Signal | What it means |
|---|---|
| High loops needed | The target upgrade may be too expensive for your current route. |
| Loop time is high | Fix the slow step before chasing rarer fish. |
| Boost changes the result | Use potions only when you can stay active. |
| Fish count rises but time rises too | Bait may not pay off until knife speed improves. |

Useful calculator scenarios
| Scenario | Change | What it teaches |
|---|---|---|
| Rod comparison | Same cash per fish, lower minutes per loop | Shows whether faster catching reaches the upgrade sooner. |
| Knife comparison | Same fish count, lower scaling time | Shows whether cleanup speed is the real money gain. |
| Bait test | Higher fish count plus realistic extra time | Reveals whether more catches help or just create backlog. |
| Luck session | Higher average cash per fish | Use only if the active route can process the better catches. |

Planner workflow
Run one normal in-game loop, count how many fish you sell, and time the full route from casting to feeding. Enter those values here, then compare your next rod cost against your next knife cost. The better purchase is usually the one that cuts loop time or raises cash per loop the most.
For the most honest result, run the same route twice: once with your current setup and once after changing only one variable. If both rod and knife numbers improve at once, you will not know which purchase mattered.
