About this site
Grow a Garden Calculator is a free, fan-made web tool that helps Roblox Grow a Garden players estimate crop values, mutation multipliers, trade fairness, and pet stats. Everything runs in your browser — no login, no tracking beyond standard analytics, no ads slowing the page down.
We update the data tables when the game patches values. The current data set is dated 2026-05-22.
Why this exists
The in-game UI doesn’t tell you exactly what a mutation combo is worth, and trade scams are common. A simple calculator that bakes the formula in and updates with the meta saves time and money.
