Guide to Jailbreak Trading Values
Trading in Roblox Jailbreak can be high-stakes, especially when dealing with limited vehicles, hyperchromes, and rare textures. Since the in-game balancing system only accounts for raw cash prices (which are often outdated for retired items), traders rely on community-defined "values" to ensure fairness. This Jailbreak Trading Calculator helps you do the math quickly to avoid getting scammed.
How to Use This Calculator
Unlike standard calculators, this tool is designed for the specific mechanics of 8-slot trading (4 items per side plus cash adjustments).
Determine Values: Look up the current trading value of your items (e.g., Torero, Beignet, Brulee) on trusted community value lists (like JB Values or various Discord servers).
Input Your Offer: Enter the numerical value of the items you are giving away in the left column.
Input Their Offer: Enter the value of the items you are receiving in the right column.
Analyze: Click the button to see the Net Value Difference.
Understanding the Results
The calculator compares the total aggregate value of both sides to determine the outcome:
Big Win: You are receiving significantly more value (15%+) than you are giving. Accept these trades immediately!
Fair Trade: The values are within a 5% margin. These are standard trades where both parties get what they want without losing equity.
Loss/Big Loss: You are giving away far more value than you are receiving. Unless you really want the specific item, you should ask the other player to add more items or cash.
Why Not Just Use In-Game Prices?
In-game cash prices often do not reflect the rarity or demand of an item. For example, a retired vehicle might have an original price of $500,000, but because it is no longer obtainable, its trading value could be over $10,000,000. Always use community values rather than the default cash price shown in the trade menu.
Common Trading Terms
OP (Overpay): When a user offers more than the item is worth to secure the trade quickly.
LF (Looking For): Items a player specifically wants.
Clean: An item (usually a vehicle) that has its original owner history or is not duped (though this is harder to track now).
Adds: Small items or cash added to a trade to balance the value difference.
