About gagdata.com
The Grow a Garden Calculator built by players, for players
GAG Calculator was built to solve one problem: Grow a Garden values change every Saturday, and every existing resource takes days to catch up. We built a calculator that updates within 12 hours of each patch — with every number verified in-game before it goes live.
The site covers 325 crops, 151 mutations, and 336 pets across eight free calculator tools — no account needed, no paywalls.
Intended audience: GAGdata.com is a data analytics and calculator resource. Our tools cover profit-per-hour analysis, ROI optimisation, seed cost calculations, trade value economics, and mutation stacking mathematics. These are complex financial and strategic concepts primarily used by older teenagers and adult players in the Grow a Garden community. This site is not directed at children under 13.
In-Game Verified
Every crop value, mutation multiplier, and pet stat is tested directly inside Grow a Garden — never sourced from community estimates or wikis.
Patch-Day Fast
After each Saturday patch, updated values are live within 12 hours. We aim to be the first accurate source after every game update.
Always Free
Every calculator on gagdata.com is free to use, with no account required and no paywalls. The site is supported by advertising, which helps keep all tools permanently free.
Mobile-First
Built for Roblox players who check values on a second device while playing. The calculators load above the fold on every phone and tablet.

How our data is verified
Load the game after each Saturday patch
Within an hour of the weekly patch going live, we open Grow a Garden and check the patch notes against what has changed in the game.
Re-test every affected crop, mutation, and pet
For each changed entry, we harvest crops without mutations to confirm base values, apply single mutations to verify multipliers, and feed pets incrementally to confirm weight thresholds.
Update the JSON data files
Verified new values are written to crops.json, mutations.json, and pets.json. The site rebuilds automatically from these files — no manual HTML editing.
Publish with a date-stamped update log
Every Saturday update is recorded in the Recent Changes section on the homepage and in the weekly update page — so you always know what changed and when.
Site history
GAG Calculator launched in 2025 to fill the data gap left by community wikis and has tracked Grow a Garden values through every weekly patch since early access.
