GAG Calculator sɣur NBK Devs

GAG Calculator is an unofficial toolbar popup for Roblox players who follow
Grow a Garden (GAG) and want fast plant value math. It is independent
of Roblox.com and the game client it does not inject into Roblox pages or read
game memory.

Who it is for

Firefox users who keep Roblox open in another window or tab and want one-click
access to the same value model (weight-based scaling, boosts, multipliers,
quantity) with minimal clutter.

What you can do

• Same plant dropdown, weight, quantity, boost %, and multiplier presets as the
Chrome build.
• Live preview while you type (no need to press Calculate to see numbers
update for preview; Calculate still logs to history when you want).
• Local persistence of your last inputs (storage on your machine only).
• Recent calculations list for quick comparisons across scenarios.
• Reset and Copy actions for workflow speed.

Formula

finalValue = baseValue * (weight / baseWeight)^2 * multiplier * (1 + boost/100) * quantity
