Grow a Garden Calculator — Free Crop Value, Mutation & Pet Calculator [2026]

How to Use the Grow a Garden Calculator

The Grow a Garden Calculator requires four inputs to produce a Sheckle value: your crop selection, your applied mutations, your crop's weight, and the number of harvests. Each input corresponds to one step in the calculation formula:

1. 1

   🌾Select Your Crop

   Click the Crop Selector dropdown and choose your crop from the full list of 303 plants, organised by rarity tier from Common through to Prismatic. The calculator loads that crop's verified base Sheckle value (per kilogram) automatically from the crops data file, eliminating manual lookup.

2. 2

   ✨Apply Your Mutations

   Toggle the Mutations panel and select every mutation present on your crop. You can stack up to five mutations simultaneously. The calculator applies each multiplier sequentially — not additively — meaning a Shocked (100x) plus a Gold (20x) mutation yields a 2,000x combined multiplier, not a 120x one. The total mutation multiplier updates in real time as you select.

3. 3

   ⚖️Enter Crop Weight

   Type your crop's weight in kilograms in the Weight field. Heavier crops yield proportionally higher Sheckle totals within their tier. The weight factor is applied after the mutation multiplier in the formula, and the calculator shows the exact calculation breakdown — base value, mutation-adjusted value, and weight-adjusted final value — in the Results panel.

4. 4

   📊Read Your Sheckle Result

   Your total Sheckle value appears in the Results panel within milliseconds. The panel displays three figures: the crop's base value, the mutation-adjusted value, and the final weight-adjusted Sheckle total. Copy the result directly or use the Share button to post your crop value to Discord.

What Does the Grow a Garden Calculator Cover?

The Grow a Garden Calculator covers every major calculation system in the Roblox game Grow a Garden — crop Sheckle values, mutation multipliers, pet weight classifications, XP time-to-age, trade Win/Fair/Loss analysis, and farming profit. As of the February 2026 patch, the calculator database includes 303 crops, 145 mutations, and 314 pets — making it the most comprehensive publicly available calculator for this game.

The crop list spans seven rarity tiers from Common to Prismatic, the mutation list covers every multiplier from Rainbow (50x) to Voidtouched (135x), and the pet database includes all Huge, Titanic, and Godly classified entries. Each data point is sourced from direct in-game testing — not community estimates or wiki scrapes. Alex Greenfield verifies every value within 12 hours of the Saturday patch using controlled in-game conditions.

The Grow a Garden Calculator covers all 303 crops, 145 mutations, and 314 pets in the game, with every value sourced from direct in-game testing rather than community estimates. The only calculator to include profit-per-hour analysis, complete 145 mutation data, and all 314 pets.

The crop value calculator is the most frequently used tool on the site, handling approximately 70% of all calculator sessions. The trade calculator is the second most used, driven by the game's active player-to-player trading economy — where Win/Fair/Loss analysis prevents costly trade losses.

Crops, Mutations & Pets — What the Data Covers

The calculator database spans three core entity types in Grow a Garden: crops (virtual plants harvested for Sheckles, the in-game currency of Grow a Garden), mutations (value-multiplying modifiers applied to crops), and pets (companions that classify into Huge, Titanic, and Godly tiers based on their weight stat). Each entity type has its own data model and its own dedicated calculator tool.

Best Mutations in Grow a Garden — Ranked by Sheckle Multiplier

Mutations are value-multiplying modifiers applied to crops in Grow a Garden. Each mutation applies a defined multiplier to the crop's base Sheckle value (per kilogram). The highest-value mutations in Grow a Garden, ranked by their Sheckle multiplier:

1. 1.Voidtouched135x— Rarest obtainable mutation
2. 2.Celestial120x— Highest non-event multiplier
3. 3.Shocked100x— Most targeted high-value mutation
4. 4.Rainbow50x— Widely available high multiplier
5. 5.Moonlit25x— Strong mid-tier mutation
6. 6.Gold20x— Common high-value mutation

Voidtouched is the highest-value mutation in Grow a Garden, applying a 135x multiplier to any compatible crop's base Sheckle value. It is also the rarest obtainable mutation in the game — as of the February 2026 patch, it is only obtainable through specific in-game events. Celestial (120x) is the second-highest and the highest mutation available through standard gameplay. Use the mutation calculator to preview the combined multiplier of any mutation combination before applying it in-game.

How the Sheckle Value Formula Works

The Grow a Garden Calculator uses a four-variable formula to compute the final Sheckle value of any crop. Understanding the formula helps players identify which variable — rarity, mutation, or weight — has the greatest impact on their specific crop's value.

Base Value is the crop's verified Sheckle-per-kilogram rate at its unmodified rarity tier. Mutation Multiplier is the combined sequential multiplier of all applied mutations. Weight Factor is the crop's actual weight in kilograms, which scales the final output linearly. The calculator applies the mutation multiplier to the base value first, then applies the weight — the order of operations matters and differs from how some players manually estimate value.

How Mutation Stacking Works in the Formula

When more than one mutation is applied to a crop, their multipliers do not add together — they multiply sequentially. The first mutation's multiplier is applied to the base value. The second mutation's multiplier is then applied to that result. Stacking two mutations produces exponentially higher outputs than a single mutation, and the order of multiplier application does not affect the final result (multiplication is commutative).

Weight and Its Effect on Final Sheckle Output

Weight scales Sheckle output linearly across all crop types. A crop that weighs 2 kilograms produces exactly double the Sheckle output of the same crop at 1 kilogram with identical mutations applied. Unlike rarity tier and mutation type, weight is the only variable in the formula that a player can control directly through in-game farming choices — making weight maximisation a core farming strategy.

Note: Some specific crops in Grow a Garden have fixed base values that are not affected by weight. The calculator flags these crops with a 'Fixed Value' indicator in the results panel. As of the February 2026 patch, fewer than 12 crops carry the Fixed Value attribute — verify in the crop database.
