Formula

added income = added slots × income per filled slot; payback = cost ÷ added income

How to collect usable inputs

  1. Enter only slots the upgrade really unlocks.
  2. Use a realistic pet rate for slots you can fill.
  3. Leave speculative multipliers out.

Limit you should keep with the result

An empty slot produces no income; the estimate assumes every added slot is filled.

For named pets and source context, cross-check the 106-slot Pet Index. For a complete set of decision aids, return to all Steal An Egg tools.
