Enter the base hatch duration
Start with the unmodified hatch time in hours so the calculator has a clean baseline for the speed adjustment.
Egg hatch ETA
Combine baseline incubation with warmth / campfire / incubator style buff percentages. Outputs hours — extend for multiplicative pets if dataminers expose more precise brackets.

How egg hatch speed is calculated
The egg hatch speed calculator converts a base hatch timer into an effective timer after speed bonuses. It helps compare incubator, warmth, campfire, or event-style bonuses before committing resources.
Apply the total speed bonus
Use the speed buff percentage for the combined bonus you want to test. The output shows both hours and approximate minutes.
Compare setups before hatching
Changing the bonus slider helps identify whether another speed source meaningfully reduces the hatch timer.
Frequently asked questions
What is effective hatch time?
Effective hatch time is the remaining timer after the selected speed bonus is applied to the base hatch duration.
Should I enter minutes or hours?
Enter the base hatch duration in hours. The calculator also displays an approximate minute total.
Does the calculator handle every hatch bonus type?
It handles percentage speed bonuses through one combined input. Add separate inputs later if your data requires different stacking rules.
