How the trade calculator works

This calculator compares the two sides of a Grow a Garden trade. You add the items you would give and the items you would get, and it tells you whether the trade is a win, fair, or a loss for you. It covers 1,017 items: 566 crops, 375 pets and 76 gear items.

The formula, in words

First it totals each side: every item's value multiplied by how many of it are in the trade. Then it weights each side by demand. Every item has a demand tier from S down to D, worth 5 down to 1, and each side gets the average tier of its items. A side's adjusted value is its total multiplied by that average divided by 3, so a side made of middle-tier (B) items is left unchanged, and a side full of S-tier items counts for more.

The verdict comes from one ratio: your adjusted value divided by theirs. If the ratio is about 0.91 or lower, you receive more than 10% more than you give, and the trade is a Win. Between roughly 0.91 and 1.11 the two sides are within 10% of each other, and the trade is Fair. Above that, you give away more than you get, and it is a Loss. The exact formula is in the "How this works" panel above the tips.

Where the values come from

The item list is built from the site's Grow a Garden crop, pet and gear databases. Most of the values are not trade prices. 941 of the 1,017 items, every crop and every pet, use a baseline this site sets by rarity, because no primary source publishes per-item trade values for them. The 76 gear items use their Sheckle shop price. Demand tiers come from rarity alone, not from what players are asking for this week. That is why the verdict is a quick sense check, not a price quote.

Trading safely

• Only trade through the game's own trade screen, where both sides must accept the same offer.
• Never hand an item to a "middleman" or go first on a promise. Nothing makes the other player finish the trade.
• Values here and on every community list are estimates, not prices the game sets. If an offer only looks fair because of one high-value item, check that item on more than one list.
• Ignore anyone who asks for your password or asks you to click a link to "verify" a trade.

Questions

How does the trade calculator decide if a trade is fair?

It adds up the value of each side, weights each side by the average demand tier of its items, and divides what you give by what you get. If the two sides are within 10% of each other the trade is marked Fair; beyond that it is a Win or a Loss for you.

Are these the prices players actually trade at?

No. 941 of the 1,017 items — every crop and every pet — use a baseline value set by rarity, so two pets of the same rarity show the same number. Only the 76 gear items use a specific figure, their Sheckle shop price. Treat the result as a rough check, not a quote.

What do the S, A, B, C and D demand tiers mean?

They are a stand-in for demand, derived only from rarity: Divine, Prismatic and Transcendent are S; Mythical is A; Legendary and Epic are B; Rare, Uncommon and Event are C; Common is D. They are not a measure of how many people want an item right now.

Does the calculator save or send my trades anywhere?

No. The calculation runs in your browser. The share button only puts the items you picked into the page link so you can send it to someone.

Is it safe to trade with someone who offers to hold items for both sides?

No. A "middleman" who takes one side first can simply keep it. Trade only through the game's own trade screen, where both players see the full offer and both must accept before anything moves.
