Crop value and weight planner
Calculate value from weight or reverse the same model to estimate the weight needed for a target value. Standard, limited, and admin-event mutations are labeled separately.

Calculation mode
Both modes use the same weight-squared, variant, environmental, and friend-boost model.
Base value should describe the unmutated crop at the reference weight. Weight factor = (fruit weight / reference weight) squared.

Scenario comparison
Add up to eight scenarios to compare crops, mutation routes, weights, and returns. They stay in this browser.
Planning model: base value x weight factor x growth variant x additive environmental factor x friend factor. Replacement combinations should be entered as the resulting badge, not counted again with their ingredients.
Player guide
How to get a useful estimate
Choose a shop preset or enter any custom crop. Calculate value from a known fruit weight, or enter a target value and reverse the same formula to estimate required weight. Then add friend boost, one growth variant, and every compatible environmental mutation.
- Leave reference and fruit weights equal when your base value already describes the exact fruit.
- Add several scenarios to compare routes without losing the current setup.
- Compare single-harvest crops against their replanting cost.
Player guide
Why the in-game number can differ
The planner separates one growth variant from environmental bonuses, applies weight as a squared ratio, and adds friend boost last. Combination badges can replace their ingredients, so the calculator flags known recipes before they are double-counted.
- Use the resulting combination badge instead of counting its ingredients twice.
- Do not assume every limited or admin mutation can coexist.
- Verify expensive sales against the current game before trading.

FAQ
Questions players ask before acting
Does the calculator read my Roblox inventory?
No. It runs locally in your browser and uses only the values you enter.
Are the Seed Shop costs current?
The presets were checked against the community Seed Shop reference on July 26, 2026. Game updates can change them.
Can I stack several mutations?
Yes. Select one growth variant and multiple environmental mutations. Environmental bonuses are added around a 1x base instead of multiplying every badge, and known replacement recipes are flagged.
