How the Grow a Garden Calculator works
No manual, no confusing menus. Four easy steps and you have your answer in under thirty seconds.
Select your plant
Browse or filter the full plant list by category โ Seed Shop, Exotic, Night, Bee, Fairy and more โ until you find the one you grew.
Apply mutations
Tap up to five mutations from the full list, or hit Max Mutations to auto-pick the strongest five for that plant.
Set friend boost
Drag the slider from 1ร to 60ร so it matches your real in-game boost. Every number updates as you move it.
Check profit & pets
Switch tabs to see net profit, ROI, and how your pet multiplier stacks on top of everything else.
Five tools inside one calculator
One page, five tools, zero clutter.
Instant Value Calculator

Profit & ROI Calculator
Type in your seed and mutation cost to see your real profit, ROI percent, and earnings per hour.

Plant categories in this calculator
Grouped the same way you see them in-game, so they are quick to find.
Mutation strategy for bigger profits
Mutations are the single biggest lever for plant value. Use the calculator to test a combo before you commit to it in-game.
Stack your best mutations first
Sort mutations by multiplier and fill your five slots with the top five before trying anything else. Small mutations rarely beat a full stack of strong ones.
Use Compare Mode before re-rolling
Before spending resources on a new mutation, open the Compare tab and check the real numeric difference instead of guessing.
Always check your friend boost
A plant that looks weak at 1ร can become your best earner at 30ร or higher. Set the slider to your real number before deciding what to sell.
Watch profit per hour
A cheap, fast plant can out-earn a slow, expensive one. The Profit tab shows earnings per hour so you plant the right crop for your time.
Built for accuracy and speed
Community-tested data
Base values and mutation multipliers come from real in-game testing, not guesswork, and get rechecked after major updates.
Zero-delay results
Everything runs in your browser. There is no server round trip and no loading spinner โ just instant numbers.
Completely free, always
No paywall, no subscription, no ad clutter. Every tool, including Profit and Pets, is open to everyone.
Mobile-first design
Check values on your phone while you play. Every slider and tab works cleanly with one thumb.
