Grow A Garden Calculator — Plant Value, Pet XP, Egg Hatch & Trades

The Grow A Garden Calculator is a unique tool that helps you climb higher on the leaderboard. It provides a complete analysis of everything from seed to trade. Rather than estimating gains, you can quickly determine the value of your plants before you harvest them, your Base KG and final harvest weight, and predict the outcome of pet ability cooldowns or hatches. Whether you're examining the win/fair/loss status of a trade, appraising rare Cryoshards, or planning your next major upgrade, the calculator uses real-time values and advanced filters to ensure you always get a fair deal.

Use a visual grid of plant icons to easily select crops and apply filters such as Seed Shop, Base Value, rarity, growth time, and profitability — making it simple to compare options and identify the best plants to grow or harvest.

Pet XP Calculator helps you determine the amount of experience your pet earns from actions or items, shows how many actions are required to reach the next level, and helps you efficiently level your pet without wasting resources.

Egg Hatch Calculator shows the chances of hatching each type of pet, estimates the result of multiple hatches, and lets you compare different eggs so you can determine whether single or bulk hatching is more profitable.

Pet Weight Calculator translates a pet's weight into its effect on stats or value, compares light and heavy pets, and shows the best weight ranges to help you decide whether to keep, upgrade, or sell a pet.

Pet Ability Calculator assesses the effectiveness of an ability by calculating its impact based on levels or modifiers, comparing abilities across different pets, and determining which abilities scale better — making it easier to decide which pets to use for farming and progression.

Click Plant Value, Pet XP, Egg Hatch, Pet Weight, or Pet Ability in the left sidebar.

• Plant Value: Select a plant, apply any mutations, enter weight and quantity, and instantly see the total value of your harvest update in real time.
• Pet XP: Enter the required values shown on screen, and watch the XP results update instantly as you adjust inputs.
• Egg Hatch: Select an egg type and related options visually, then view hatch results without switching pages.
• Pet Weight: Input pet details and weight values to calculate outcomes in real time.
• Pet Ability: Choose abilities from the interface to see how they affect performance or value.

Gag Calc uses an exact in-game weight-to-price formula, which is reverse-engineered from the real game through in-game testing.

It provides the correct stacking rules for multiple mutations. Unlike other calculators, it properly accounts for dynamic in-game events such as Blood Moon or Eclipse — you can opt into those effects for event-specific mutation value boosts.

It also models gadget and tool impacts, such as how sprinklers or other gear affect crops (growth rates, mutation chances). Because of their value impact from auxiliary effects, pet tools, or modifiers, Gag Calc gives you ranked guidance — not just raw calculations.

It supports bulk inventory planning, portfolio value management across multiple crops and pets, and trade optimization for larger inventories. Overall, gagcalc.io is designed to give you the most accurate, adaptable, and strategic insights possible — and to prevent you from under-selling rare plants.
