Grow a Garden Incubator Efficiency Calculator
Measure hatch-speed gain, XP acceleration, offline output, and real time saved before you spend crops as fuel.
Calculator Inputs
Model your actual uptime instead of assuming a perfect 24/7 incubator.

Interpretation Guide
Fuel uptime matters more than headline multiplier
A 3× incubator that is fuelled only 70% of the time behaves like a 2.1× incubator before any external boosts.
External boosts should be treated as burst windows
Toggle them on only for realistic sessions. Otherwise your plan will overestimate hatch throughput or XP generation.
Use this to prioritize where fuel goes
If you cannot keep both incubators running, compare the time saved here and send your best crops to the higher-impact queue.
FAQ – Incubator Efficiency Calculator
It converts the incubator’s listed multiplier into practical outcomes such as real hatch-time savings, XP generation, and offline progress under your own uptime assumptions.
