This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own Steal A Fish session. It will not click the shop.

Upgrade payback

Fish payback estimator

Estimate how many minutes a flat-income fish needs to cover its cash price. Enter the river price, convert its cash per second into cash per minute, and leave the cycle at 1 minute. This is arithmetic on the numbers you type, not a live readout of your base.

Enter values from your session.

Payback cycles = upgrade cost ÷ extra profit per cycle, rounded up.

Demo defaults use the listed Turtle price of 350 cash and 17.50 cash per second. Multiply cash per second by 60 and enter that as cash gained per minute, then keep the cycle at 1 minute. The estimate is price divided by that minute rate. It ignores theft, mutations, percent fish, rebirth multipliers, and the offline cap.

FAQ

Steal A Fish calculator questions

What do you actually do in Steal A Fish?

Fish come out of a tunnel and travel a river conveyor. Press E to buy one with cash. It walks to an empty pad in your house and generates cash every second. Step on the green floor button to claim that cash. Other players can carry a fish away if your force field is down and the fish is not Unstealable.

Does rebirth delete the whole base?

Written guides current through October 19, 2026 say a rebirth removes only the cash and the exact fish named on that level. The rest of the aquarium stays. One July 2025 play video described a wider loss of stolen fish, so confirm the checklist on the Rebirth button before you confirm.

Why do some fish not show a flat cash-per-second number?

A percent fish pays a share of your single best flat-income fish. Hungry Deer is listed at 150 percent, The Moon at 160 percent, and Cthulhu at 250 percent. If that flat anchor is sold, stored in the vault, or stolen, every percent fish drops with it.

Where is the Fish Vault and does it make money?

The Fish Vault is on the top floor after a late rebirth. Fish inside cannot be stolen, and they also stop generating cash. Use it for rebirth ingredients and prizes, and leave your best flat earner on a normal pad.
