Grow a Garden Calculator
Pick a plant, stack your mutations, and slide in your friend boost. See the real sell price, your profit, and your pet stats before you touch the soil — all free, all instant.
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 — Seed Shop, Exotic, Night, Bee, Fairy and more — 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 1× to 60× 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
Your plant value updates the second you tap a mutation. No submit button, no waiting, no page reload.
Profit & ROI Calculator
Type in your seed and mutation cost to see your real profit, ROI percent, and earnings per hour.
Side-by-Side Compare
Put two plants next to each other and instantly see which one is the stronger pick.
Pet Calculator
Check hatch times and value multipliers so your pet strategy lines up with your planting strategy.
Session History
Pin any result to your history list so you can compare it again later without redoing the maths.
Always Free
No ads, no account, no locked tab. Every feature here is open to every player.
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 1× can become your best earner at 30× 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 — 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.

Grow a Garden Calculator — FAQ
Quick, plain answers about how the calculator works.
What is the Grow a Garden Calculator?
It is a free browser tool that works out the exact sell value of a plant after mutations and friend boost are applied. It also includes a profit calculator, a plant comparison mode, a pet calculator, and a calculation history.
How accurate is the plant data?
Values are built from community testing and are checked again whenever the game changes. If a number ever looks off, you can override it yourself with the custom base value field.
How do I use the mutation calculator?
Pick a plant, then tap up to five mutations. Each one is a multiplier that stacks with the others. The total updates on screen the moment you tap, so there is nothing to submit.
What does the friend boost slider do?
Friend boost is an in-game bonus that grows with the number of friends in your session. Drag the slider to match your real boost so every number on the page reflects your true game state.
Can I calculate profit and ROI?
Yes. Open the Profit tab, enter your seed cost, mutation cost, and grow time. You get back net profit, ROI percent, and profit per hour.
What is the Pet Calculator for?
It shows typical hatch times and value multipliers for pets, so you can see how a pet bonus stacks with your plant value.
Can I save my calculations?
Yes. Tap Add to History on the Plants tab and the result is pinned to your History list for the rest of your visit.
Does the calculator work on mobile?
Yes. The whole layout adapts to small screens, and the slider and buttons are sized for one-thumb use.
Is the calculator free to use?
Yes, completely free. There is no sign-up, no payment, and no locked feature.
How often is the plant list updated?
We review the list after every major game update and add new plants and mutations as soon as community testing confirms the numbers.
What does Custom Base Value do?
It lets you type in your own starting value instead of the database number. Handy for testing a plant that was just changed by a patch.
Does this site cover every plant category?
Yes — Seed Shop, Exotic, Limited, Easter, Night, Bee, Summer, Prehistoric, Zen, Cooking, Beanstalk, Fairy, Fall, Halloween, Safari, and Special Seeds are all included.

Open the CalculatorAbout EasyCalculatorSmart
We built EasyCalculatorSmart because working out plant value by hand was slowing down our own play sessions. Here is who we are and how we keep the numbers honest.
Why we made this tool
EasyCalculatorSmart started as a small side project between a group of players who kept a shared spreadsheet of plant values, mutation multipliers, and friend boost math. The spreadsheet worked, but it was slow, easy to break, and useless on a phone. We turned it into a proper web tool so any player could get the same answer in a few taps.
How we test our data
Every base value and mutation multiplier in our database comes from direct in-game testing done by real players in our community. We run each plant and mutation combination more than once before adding it, and we re-check the whole list after every major game update. If you ever spot a number that looks wrong, use our contact page to let us know.
What makes EasyCalculatorSmart different
Most value calculators only do one job. Ours combines plant value, profit and ROI, a side-by-side comparison mode, and a simple pet calculator on a single page, so you never have to jump between tools mid-session.
Our promise
EasyCalculatorSmart will always stay free. There is no sign-up wall, no premium tier, and no ad clutter blocking the tools. We built this for players, by players, and we intend to keep it that way.
Not an official tool
EasyCalculatorSmart is an independent, fan-made project. It is not affiliated with, endorsed by, or connected to the official Grow a Garden game or its developers. Read our full disclaimer for more detail.
