Trade Calculator (WFL)
Add what you give and what you get. The checker compares real trade demand tiers and calls it: win, fair, or loss. No login, runs in your browser.

Verdicts compare demand tiers, not sentimental value. Check any pet's full breakdown in the pet tier list or calculate crop values with the crop calculator.
How the verdict is calculated
Every pet carries a demand score based on its tier in the current value list: S-tier counts 8, A-tier 4, B-tier 2 and C-tier 1. The calculator adds up both sides and compares the totals. If the difference is within 20 percent, the trade is fair; beyond that it's a win for whoever receives more demand.
The scores are deliberately transparent so you can sanity-check any verdict yourself: one S-tier equals two A-tiers, one A-tier equals two B-tiers. If someone offers you four C-tier pets for your A-tier, the math says fair — but demand math also says four filler pets are harder to re-trade than one good one. When a verdict says FAIR, pick the side you'd rather hold.
FAQ
What does WFL mean?
Win, Fair or Loss — the question every trader asks before accepting. A win means you receive more value than you give, fair means both sides are close, and a loss means you're giving away more than you get back.
What counts as a fair trade in Grow a Garden?
Same demand tier for same demand tier is the baseline: an A-tier pet for another A-tier pet is fair. Trading up a tier normally requires add-ons, and no number of C-tier filler pets fairly buys an S-tier grail.
How do I avoid getting scammed in trades?
Check tiers before accepting, never rush a trade because the other player pressures you, and be suspicious of anyone who insists their pet is 'about to go up in value'. If a trade needs a sales pitch, it's usually a loss.
Does the calculator work for crops too?
This checker compares pets by demand tier. For crops, use the crop value calculator, which computes exact sheckle values from base value, mutations and weight.
