Formula Notes & Sources

Garden Value Calculator is an independent fan tool for estimating crop sales and comparing listed values. It is not affiliated with Roblox or either game's developers. Values come from community guides and your inputs, not a collection of completed player trades.

Grow a Garden: community preset

Choose a crop, enter its weight, then add its variant, environmental mutations, quantity and friend boost. This is a community estimate of sale value.

Grow a Garden formula

GAG1 = base * (kg / reference kg)^2 * variant
  * [1 + sum(environmental factor - 1)]
  * quantity * (1 + friend boost / 100)

Environmental mutations contribute their listed factor minus 1 to the pool. The selected variant multiplies that pool.

Grow a Garden 2: your sale observations

Start with the sale value and weight of a crop from your game. Same-weight mode totals identical crops. To estimate a different weight, choose linear scaling, squared scaling, or a curve fitted to two sales.

Match the crop, mutation, freshness and boosts across your sales. Linear and squared scaling are assumptions; two sales only describe those conditions. They cannot reveal minimum prices or mutation caps. Leave an extra multiplier at 1 if it is already included in the sale.

How the sale estimate is calculated

estimate = observed sale * (target kg / observed kg)^exponent
  * additional measured multiplier * quantity
fitted exponent = log(sale 2 / sale 1) / log(weight 2 / weight 1)

Shared links include the sale values and settings you enter.

Limits of GAG2 community presets

The optional preset assumes a 1 kg starting weight, squared weight scaling and one mutation factor. This site has not tested those assumptions against its own GAG2 sales. The GAG2 value guide, read September 7, 2026, also describes its crop research as awaiting in-game checks. Its listed values are not measured prices at 1 kg.

GAG1 and GAG2 mutation records stay separate. A mutation from the other game is ignored. Do not carry one game's factors into the other.

Sources and price dates

The most recent crop source check is Jun 27, 2026; for mutations it is Jun 27, 2026. Individual entries can be older. Check each item's own date and source, and compare it with the value shown in your game.

Sale prices, shop costs and player trades

Crop sale estimates, seed and pet shop costs, and player trade offers measure different things. The WFL tool compares listed totals from one game and one item type. It cannot decide a fair trade or compare mixed games, crops against pets, or unpriced items.

Pets and items use listed value × quantity; weight and mutations do not apply. Crop value divided by seed cost is only a ratio: it excludes growing time, repeat harvests, availability and boosts, so it is not profit per hour.

Trade difference ratings and the 8% range

The difference is divided by the higher total. Gaps up to 8% are close; over 8% slightly uneven; over 18% uneven; over 35% very uneven. For a Side A total of A, the close range for Side B is 0.92 × A through A / 0.92, rounded inward to whole points. These are calculator cutoffs, not game rules.

Stock reminders and corrections

The stock timer uses your device clock and starts with a 5-minute reminder. It does not track live inventory or server resets. Set your interval and restart it when you see a shop reset. Check pets and weather separately in Roblox.

If a listed value differs from your game, check the crop, weight, boosts and date. Use your own sale value in the calculator and keep a screenshot or note for comparison.
