Plan pets with numbers, not guesswork
The Pets calculator helps you plan pet progression in Grow a Garden. You can estimate effective pet weight, check hatch speed with a hatch speed bonus, and see cumulative XP needed to reach a level. It is designed for quick planning: tweak the numbers on the right to match what you see in your run, and the estimates update for you.
Effective weight, explained simply
Displayed weight and effective weight are not always the same. Past 100 kg, the tool uses a damped model: only one-quarter of the extra mass counts toward effective weight for scaling. That matters because a very heavy pet does not keep gaining value at the same rate forever. If your pet is under 100 kg, the model is simpler; if it is over, the damping is the part most players miss.
How to use the Pets page
- Enter the displayed or raw weight.
- Add the base hatch time in seconds.
- Add any hatch speed bonus as a percentage.
- Check the XP milestones for the level you are aiming for.
- Compare pets before you hatch, trade, or invest XP in one of them.
Pets are flexible by design — hatch and XP are estimates, and weight uses the damped model described above. Use the results to compare options, then confirm in the game before a major decision. For plant values, return to the main calculator.
