What Win, Fair, and Lose mean

In GPO trading, WFL is shorthand for the three outcomes of any trade, judged by total value:

WIN: You receive more value than you give.
FAIR: Both sides are within about 10% of each other in total value.
LOSE: You give more value than you receive.

How to check a GPO trade fairly

List everything on your side of the trade and everything on their side, including quantities.
Look up the current value of each item in the value list or the calculator.
Add up the total value of each side.
Compare the two totals. Within about 10%, it's fair. If one side is clearly higher, that side is winning.

The gpovalues.com trade calculator is the actual WFL tool. Add items to each side and it sums the values and shows the verdict instantly, so you don't have to do the arithmetic by hand. Open the WFL trade calculator

Worked examples using real GPO values

These use live values from gpovalues.com as of 2026-09-10, derived from 173,992 observed Discord trades. The verdict for each is computed from the real numbers, nothing is hand-picked.

Example 1 FAIR

Checking whether a Dark Blade is worth a Pika plus a Mythical Fruit Chest.

You give Dark Blade ×1 (21,782) = 21,782

You get Pika ×1 (7,576) + Mythical Fruit Chest ×1 (13,225) = 20,801

-4.5% difference: within the fair band. This is an even trade.

Example 2 WIN

Stacking two mid items against a single high-value chest.

You give Mythical Fruit Chest ×1 (13,225) = 13,225

You get Pika ×2 (7,576) + Dark Blade ×1 (21,782) = 36,933

+179.3% difference in your favor. You receive more value than you give up, so this is a win.

Example 3 FAIR

Trading a stack of one item for a single higher-tier blade.

You give Pika ×3 (7,576) = 22,727

You get Dark Blade ×1 (21,782) = 21,782

-4.2% difference: within the fair band. This is an even trade.

Values move as new trades come in, so always re-check in the calculator before you accept a trade.

If the calculator says you are short and no combination on your side closes the gap, the other way to close it is to buy the difference: the PetMart GPO store sells fruits, chests, weapons and accessories for cash. PetMart is our own shop — the same people run both sites, and we make money when you buy there. It does not move the values.
