PLAYER-ENTERED VALUES

Calculate before you commit

Starting values are editable examples, not game defaults. Replace every field with what you observe in your current server.

POSITIVE ENTERED INCOME DELTA+140/s
Inputs combined
360/s
Output entered
500/s
Fee payback
1.19 min

Formula

income delta = output rate − sum of input rates; fee payback = fee ÷ positive income delta

How to collect usable inputs

  1. Enter every pet consumed by the fusion.
  2. Use displayed income from the same server and boost state.
  3. Treat a non-positive delta as a collection choice, not an income upgrade.

Limit you should keep with the result

Fusion recipes and outputs can change; this evaluates only the values you enter.
