Grow a Garden Calculator for fruit value and pet KG
Use our free Grow a Garden Calculator to check fruit value in seconds, stack mutations like Shocked and Disco, and see your pet KG at any level. It is a fast GAG value calculator for smarter selling, fairer pet trades and bigger pets, with no sign-up needed.
How the Grow a Garden value calculator works
Every number comes from a simple, transparent formula, so you can double-check it in game.
Fruit value formula
Value scales with the square of your fruit's size compared with its base weight, then multiplies by variant and mutations.
Mutation stacking
Mutations add their bonuses together before applying, so Wet plus Chilled is far smaller than Shocked or Disco on their own. Playing the sequel? Mutations work differently there, so see the Grow a Garden 2 wiki mutations guide.
Pet KG formula
Pets gain weight with every level. Enter base kg and level to see current size and the level you need for a target weight.
Grow a Garden fruit calculator: plant value, weight and sell price
The biggest jump in sheckles rarely comes from planting more. It comes from weight and mutations. Because value grows with the square of size, a fruit that is twice the base weight is worth about four times as much before any bonus is added. This is why a weight calculator for Grow a Garden matters: a few extra kilograms change your sell price far more than you would guess by eye. Want worked examples with the full step-by-step maths? Read the complete walkthrough.
Worked example
A Watermelon has a base price of 2,708 and a base weight of 7.3 kg. At 14.6 kg it is twice the base size, so its size factor is 2² = 4. With no variant and no mutation, the estimate is 2,708 × 4 = 10,832. Add Shocked (×100) and the mutation total becomes ×100, so the same fruit is estimated near 1.08M. Try these exact numbers in the fruit tab.
Which mutations pay the most?
| Mutation | Multiplier | What it means for you |
|---|---|---|
| Wet / Chilled | ×2 | Common weather boosts. Easy to get, so stack them early. |
| Bloodlit | ×4 | A solid upgrade that appears during special events. |
| Frozen | ×10 | A big jump. Worth holding a heavy fruit for. |
| Shocked | ×100 | One lightning hit can change your whole day. |
| Celestial / Disco | ×120 / ×125 | Top tier. Check the price here before you trade it away. |
Sell the heavy ones
Weight is squared, so your single biggest watermelon can beat ten average ones. Run it through the sell calculator first.
Never sell a Gold fruit blind
Gold is ×20 and Rainbow is ×50. Enter the variant above to see what you are really holding.
Compare before you trade
Put both offers in the fruit value calculator. A trade that looks even can hide a huge gap in value.
Grow a Garden pet size calculator: KG and age by level
Every pet has a base weight, and that number rises as your pet levels up. In this pet calculator, age means level, so one tool answers both "how heavy is my pet" and "what level do I need". Heavier pets look better in a showcase and are worth more in trades. Use the Pet KG tab for your exact size, or check these examples.
| Pet | Base kg | Level 50 | Level 100 |
|---|---|---|---|
| Bunny | 2.0 | 12 kg | 22 kg |
| Dog | 3.0 | 18 kg | 33 kg |
| Monkey | 6.0 | 36 kg | 66 kg |
| Pig | 7.0 | 42 kg | 77 kg |
Want to know the level for a target size? A Dog (3 kg base) needs level 50 to reach 18 kg, because 3 × (1 + 50 ÷ 10) = 18. Planning a swap? Add up both sides of the deal before you accept, or see what a Dragonfly is worth in Grow a Garden. Playing the sequel? Browse the Grow a Garden 2 wiki pets list.
Grow a Garden trade value calculator: check a deal before you accept
A fair trade starts with knowing what each side is worth. Use the fruit tab above to price every fruit you offer or receive, and the Pet KG tab to see how heavy each pet is. Then add up both sides. For pet swaps with mutation bonuses, our dedicated trading calculator for Grow a Garden pets does the sums for you and flags uneven deals. Not sure what a pet is worth first? Check the Grow a Garden value list.
- Price each item separately, then compare totals.
- Check variant and mutations on both sides. Gold and Rainbow change value fast.
- For large trades, confirm the final numbers in game before you accept.
Pet ability and cooldown calculator: what this tool covers
This page calculates pet weight and level. It does not calculate pet abilities or cooldown timers, because those values differ by pet and change between game updates. Check the pet's description in game for its current ability and cooldown. To judge whether an ability pays off, see the Golden Dragonfly payback calculator, which estimates the days a pet needs to earn back its cost.
How we build and check these numbers
Crop base prices, base weights, mutation multipliers and pet base weights are stored as plain values in the page, and the formulas are shown above so you can verify any result. The calculator adds mutation bonuses together instead of multiplying them, which keeps estimates realistic. Roblox games change often, so numbers are estimates and may lag behind a new update. GAG Calc is a fan-made project and is not affiliated with Roblox or the Grow a Garden developers. See our About page to learn who maintains the tool, or contact us if you spot a wrong value.

How to Calculate Crop Value in Grow a Garden
What Does a Grow a Garden Calculator Actually Do?
It takes a few details about your crop and turns them into an estimated sell price. You enter the crop type, its weight in kilograms, whether it is Normal, Gold or Rainbow, and any mutations on it. The tool then does the maths that would take you a few minutes by hand.
The main idea is simple. A crop's value depends on its size compared with the normal size for that crop. A heavier fruit is worth more, and the jump is bigger than most people expect. A calculator only estimates a sell price. It cannot predict what another player will pay in a trade, because trade value depends on demand, which changes all the time.
Why Weight Matters More Than You Think
Here is the part that surprises new players. Value does not grow in a straight line with weight. It grows with the square of the size difference.
Imagine a carrot that is twice as heavy as an average one. It is not worth twice as much. It is worth about four times as much (2 × 2 = 4). A fruit three times the normal size is worth around nine times as much (3 × 3 = 9).
This is why one giant crop can beat a whole basket of average ones. Before you sell a basket, check your single heaviest fruit on its own. It may be the most valuable thing you own.
One caution: if the crop's "normal weight" in your calculator is slightly off, the error is squared too. That is why the weight you type in should match the in-game number exactly.
How Variants Change the Price
Every crop comes in a variant. Normal is the base. Gold multiplies the value by 20, and Rainbow multiplies it by 50.
That makes variants a quick way to spot a hidden jackpot. A Gold fruit of average size (20× its base price) can be worth more than a Normal fruit that is four times the normal size (4 × 4 = 16×). Always select the correct variant before trusting the result, because forgetting it is the most common reason people undersell.
Understanding the Grow a Garden Calculator Mutation Bonus
Mutations are special effects that appear on crops, often from weather or events. Each one adds a bonus to the final value. Some are small and easy to get. Others are rare enough to change your whole day.
| Mutation | Bonus |
|---|---|
| Wet, Chilled | ×2 |
| Bloodlit | ×4 |
| Frozen | ×10 |
| Shocked | ×100 |
| Celestial, Disco | ×120 to ×125 |
A fruit can carry more than one mutation, and the way they combine matters. In our calculator the bonuses are added together rather than multiplied. The method is to take each mutation's bonus, subtract 1, add those amounts up, then add 1 back.
A fruit with Wet (×2) and Chilled (×2) gets 1 + 1 + 1 = ×3, not ×4. This keeps estimates realistic and stops small bonuses from inflating the total. Because games change how stacking works, always compare our result with the in-game price when a lot is at stake.
The practical lesson is that one rare mutation usually beats several common ones. If you have the choice between holding a crop with a single Shocked bonus (×100) or one with three weak ×2 mutations (combined ×4), the single rare one is worth far more.
A Quick Example
Say you have a pumpkin that weighs about twice the normal size, with a Frozen mutation (×10) and a Normal variant. Here is the full calculation:
| Step | Working | Result |
|---|---|---|
| Size effect | 2 × 2 | ×4 |
| Variant (Normal) | no bonus | ×1 |
| Mutation (Frozen) | one mutation | ×10 |
| Total | 4 × 1 × 10 | ×40 base price |
Your pumpkin is worth about forty times its base price, from one lucky mutation and good growing.
Now picture someone offering you a price based on the base value alone. Without a quick calculation, you would never know what you gave up.
Four Mistakes That Cost Players Sheckles
Ignoring the variant. Gold and Rainbow multiply everything. Forgetting to select them is the easiest way to undersell.
Selling in bulk too early. Because of the squared weight rule, your biggest fruit deserves its own check. Do not bury it in a bulk sale.
Trusting a trade that looks even. Two offers can seem equal and still hide a large gap. Put both into the calculator and compare the totals.
Using old numbers. Updates change prices, mutations and pet stats. If a guide or tool has not been refreshed in a while, double check.
Grow a Garden calculator FAQ
What is the Grow a Garden calculator?
It is a free tool that turns your fruit weight, variant and mutations into an estimated sheckle value, and your pet's base weight and level into its current kg. It is made for new gardeners checking if a carrot is worth selling, traders who need a fair price, and veterans chasing the heaviest fruit.
How is Grow a Garden fruit value calculated?
Fruit value equals base price × (fruit kg ÷ base kg)² × variant × mutation total. Variant is ×1 for Normal, ×20 for Gold and ×50 for Rainbow. Because size is squared, a slightly bigger fruit can be worth far more than you expect.
How do I use the pet KG and age calculator?
Open the Pet KG tab, pick your pet and enter its level. The tool shows its current weight and its weight at level 100. Type a target weight, such as 20 kg, and it tells you which level you need to reach.
What is the formula for pet weight?
Pet weight in kg equals base weight × (1 + level ÷ 10). A pet with a 3 kg base is 18 kg at level 50 and 33 kg at level 100.
Do mutations multiply each other or add together?
In this calculator they add together. A fruit with Wet (×2) and Chilled (×2) gets a combined ×3, not ×4. Rare mutations like Shocked or Disco dominate the total, so one great mutation usually matters more than many small ones.
Is there a trade calculator for Grow a Garden?
Yes. Price each fruit with the calculator above, then use the pet trading value calculator to add both sides of a deal and see if it is fair.
Does the calculator show pet abilities or cooldowns?
No. It calculates pet weight and level only. Abilities and cooldowns vary by pet and change with updates, so check the pet in game for current values.
Are the results exact, and how often are values updated?
The results are close estimates, not official numbers. The game changes crop prices, mutations and pet stats during updates, so treat the answer as a strong guide and confirm high value trades in game.
Can I use the calculator on my phone?
Yes. The site is built for mobile, works in any modern browser, needs no download, and never asks you to log in or share your Roblox account.
Does this calculator work for Grow a Garden 2?
This calculator uses the formulas of the original Grow a Garden. In Grow a Garden 2, mutations do not stack the same way. Use our sequel wiki page for separate seed, mutation and pet calculators.
