⚖️ In-Game Trade Calculator (40% rule)
It answers just one question: will the game block this trade? Once you add both sides' items, we check the 40% threshold using in-game trade values; this isn't a market win/loss verdict.
First time here? Learn the 40% rule in 30 seconds
First choose the trade items on the left and right. Green means the system will allow it; red means the value gap is too large. Permanent fruits and certain items may get extra leeway or special handling, and the result panel will tell you directly.

If this shows the trade is allowed, it only means the game's 40% rule won't block it; we still recommend checking player-market values before you accept.
❓ 40% Trade Calculator FAQ
Q: If it says I can trade, does that mean I'm winning?
Not necessarily. This page only checks whether the in-game trade will be blocked by the 40% rule; to see if it's a win, use the W/F/L Trade Calculator.
Q: Why can Permanent fruits or game passes sometimes be traded even with a big value gap?
Some items get in-game leeway or special handling, so this tool estimates using the bonus and ignore rules set in our database.
Q: What else should I check before accepting?
Check BF fruit values and the demand on the Player Market first, then decide whether to trade.
