About Grow a Garden Calculator
Welcome to Grow a Garden Calculator — a premier, fan-made utility built to help players get the most out of every session. Whether you are optimising plant values, levelling pets efficiently, or timing your egg hatches to perfection, our tools are designed to give you fast, accurate answers so you can focus on playing, not mental maths.
What We Offer
Our suite of free calculators covers four core areas of the game:
- Plant Value Calculator — instantly estimate the sell value of any plant based on its weight, rarity, mutations, and active boosts.
- Pet XP & Levelling Calculator — find out exactly how many treats, hours, and helper pets you need to reach your target age.
- Egg Hatch Timer — account for kiwi and eagle birds, speed bonuses, and hatch-rate modifiers to see your real wait time.
- Pet Ability Calculator — model a pet's ability output at any age, weight, rarity, and buff combination.
Who Built This?
Grow a Garden Calculator was created and is maintained by passionate fans of the game. We built the tools we wished existed — free, ad-light, and mobile-friendly — so the wider community could benefit. Every formula is researched from community data, patch notes, and extensive in-game testing.
Staying Up to Date
The game is actively updated, and so are our calculators. Whenever new plants, pets, or mechanics are introduced, we update the underlying data and formulas as quickly as possible. If you spot an error or a missing item, please reach out through our contact form — community feedback is how we keep everything accurate.
