About Grow a Garden Calculator

What we build

Grow a Garden Calculator is a focused web tool for players of the Roblox experience Grow a Garden. Instead of juggling spreadsheets, screenshots, and mental math during trades, players can enter a pet's weight, age, and mutation — or a fruit's weight, size, and mutation — and get a clear estimated value in seconds.

The site currently ships six calculator modes:

• Pet Value — value from kg, age (1–500), and mutation
• Value ↔ Weight — convert between price and kilograms
• Trade WFL — Win / Fair / Lose verdict with percentage gap
• Fruit Value — crop pricing with size and stack bonuses
• Age 1–500 Planner — growth, XP, and timeline estimates
• Mutation Stack — multiplicative mutation combinations

How we approach accuracy

No third-party fan tool can promise perfect in-game prices — games update, and markets move. What we can do is be transparent. Every result shows its multiplier breakdown: base per kg, mutation tier, age curve, weight, and any bonuses. If a number looks off, you can see exactly which term produced it.

Our formulas are documented on the tool page and in our blog guides, so you can replicate the math yourself or compare it with other community resources.

Privacy by design

The calculator is 100% client-side. There is no account system, no login, and no backend that receives your inputs. Numbers you type stay in your browser. See our Privacy Policy for the full picture.

Who this is for

• Traders who need a quick WFL check before accepting an offer.
• Collectors comparing pet weight and age across listings.
• New players learning how mutations and age change value.
• Content creators who want consistent numbers for guides and videos.

Independence and affiliation

This is an independent fan project. We are not affiliated with, endorsed by, or sponsored by the game, its developers, or Roblox Corporation. All game names and related marks belong to their respective owners. Our disclaimer has the full details.

What we will not do

• No fake testimonials, awards, or fabricated statistics.
• No paywalls on core calculator functions.
• No selling or transmitting your calculator inputs.
• No misleading buttons or deceptive download links.

Feedback and improvements

Base tables and multipliers evolve with the game. If you spot a formula that looks wrong or want a calculator mode added, get in touch. We review feedback regularly and update the tool when the community consensus shifts.
