Roll a Fisherman Rebirth Calculator

Decide whether to rebirth now: compare the rebirth income boost against what you lose and how long it takes to break even.

Enter your current income rate, the cash you are holding, and the rebirth income multiplier. The calculator compares the boost against what you give up to decide whether to rebirth now.

Your total income per minute before rebirth.
The cash you effectively reset or spend on rebirth.
How much rebirth multiplies income (1 = no change).

How to use

  1. Enter your current income rate and saved cash.
  2. Enter the rebirth income multiplier (for example 2 for 2x).
  3. Read the new income, the break-even time, and a plain verdict on whether to rebirth now.

Examples

Rebirth now

If rebirth doubles income and your saved cash is small, you break even fast — rebirth as soon as the next purchase is out of reach.

Wait

If rebirth only adds 10% income and you are still buying cheap fishermen, waiting keeps your short-term income higher.
