Steal a Fish Calculator is a free Roblox tool that helps players calculate coins per second (CPS), earnings per minute and hour, and estimate rebirth ETA with slot planning for the popular Roblox game Steal a Fish. This calculator is updated for Deep rarity (10 CPS), Magma mutation (0.5% chance, ~50 CPS), and the 20-slot rebirth unlock system.
The calculator supports all fish types including Common (1 CPS), Uncommon (2 CPS), Rare (5 CPS), Deep (10 CPS), and the ultra-rare Magma mutation (50 CPS). It accounts for the 30% update buff and helps you plan your rebirth strategy by calculating how long it takes to reach target cash amounts.
Choose your fish type from the dropdown (Common, Uncommon, Rare, Deep, or Magma). Enter the number of fish slots you have (1-20). Levels 9 and 10 of rebirth unlock 5 additional slots each, bringing the maximum to 20 total slots.
Toggle the 30% update buff checkbox if your server has the current update buff active. This multiplies your CPS by 1.3x, significantly increasing your earnings.
The calculator automatically displays your coins per second (CPS), coins per minute, and coins per hour based on your fish type, slots, and buff settings. Use these numbers to compare different setups.
Enter your current cash, target cash for rebirth, and your actual CPS. The calculator shows the estimated time (ETA) to reach your target, helping you plan when to rebirth and optimize your progression.
