EFF Calculator

Ant efficiency with mutation, jelly and food gain boosts.

Ant base EFF (from the slot)

= 100K

Mutation

Food Gain Multiplier (%)

As shown on the upgrade board, e.g. 420

Speed jelly

Other multipliers (pets, skins…)

Combined, e.g. 1.4 for a +40% tree skin

Food per trip

100K

Output score (food per trip × speed)

100K

Speed jelly multiplies trips per minute, not food per trip.

Assumes all multipliers stack multiplicatively. The game does not show its exact formula, so treat results as estimates for comparing options.

How to use it

Enter the ant's EFF shown on its nest slot (before mutation if you are planning one).
Pick the mutation and the Food Gain % from your upgrade board.
Add any other boosts you know of (a +40% tree skin is 1.4).
