Grow a Garden Pet Calculator

Estimate a pet’s value in Grow a Garden from its base value, age and weight, then check any trade with a Win / Fair / Lose comparator.

What this calculator does

This fan-made pet calculator for the Roblox game Grow a Garden gives a transparent value estimate for pets. Unlike crops, pets don’t follow one fixed in-game formula — their worth comes from rarity, age and how much the trading community wants them — so this tool builds a starting estimate from the numbers you can control and lets you compare trades side by side.

Enter the pet’s community base value, its age and an age factor (how much each age level adds), plus weight against a base weight. The calculator returns an estimated value and feeds it straight into the WFL trade check.

How to use it

  1. Enter the pet’s base value — the community value at a young age.
  2. Add the age and an age value factor (0.05 means each age level adds about 5%).
  3. Enter the pet’s weight and a base weight for its kind to scale by size.
  4. Read the estimate, then enter both sides of a trade in the WFL box to see if it’s a win, fair or a loss.

Formula reference

estimate = base value × (1 + age factor × age) × (weight ÷ base weight) × qty WFL compares your side’s total value against theirs

A worked example

Worked through, a base value of 1,000, quantity of 1 produces a pet value of 1K. Underneath, Age multiplier comes out at ×1 and Weight multiplier at ×1. Change any field and every figure updates as you type.

Common questions

Do pets have a fixed value formula?
Not really. Pet worth in Grow a Garden comes mostly from rarity, age and community demand, so treat any number here as a starting estimate rather than an official price.
Does age increase a pet’s value?
Generally yes — older, higher-level pets are usually worth more because they take time and resources to raise. Adjust the age factor to match current community sentiment.
How should I use the WFL check?
Add up the value of everything on each side of the trade, enter the two totals, and the comparator flags whether you’re winning, it’s fair, or you’re losing.
Why does my estimate differ from a trade site?
Different sites weight age and demand differently, and prices move fast. Use several sources for anything valuable.
