Does Trade Check use official item values?
No. Every item score comes from you, and the result is a decision aid rather than a market price.
Add every item on both sides, use one score scale, choose your own preference percentages, and label how confident you are in the inputs.
PLAYER-INPUT TOOL
Score up to six item rows per side on one consistent scale. Preferences begin at 0% and remain visible.
Use one consistent scale for how much each item matters to you. The calculator does not look up a price from an item name. Do not mix coin amounts, rarity percentages, and personal points in the same comparison.
Leave both preference settings at 0% for your first comparison. If you cannot reasonably compare the items, the result is not reliable just because it produces a number.
Add an item score and quantity on each side to start a comparison.
Not an official market value. Scores, confidence, and preferences come from you. Always recheck the final items and quantities in Roblox.
This is a made-up points example explaining the calculator. Item A and Item B are placeholders, not named squishies, official values, or recommended trades.
Keep Duplicate preference and Collection-gap preference at 0%.
| Side | Example item | Score per item | Quantity | Total score |
|---|---|---|---|---|
| You give | Item A | 40 | 2 | 80 |
| You receive | Item B | 80 | 1 | 80 |
With no preference adjustment, the comparison is:
Received total ÷ offered total = 80 ÷ 80 = 1.00.
The totals match on the scale you entered. This does not prove equal rarity, equal market demand, or that either player should accept.
If you change the received item's score to 60 while keeping everything else the same, the ratio becomes 60 ÷ 80 = 0.75. Your entered return is now lower than your entered offer. Changing the opinion supplied to the tool changes the result; it does not change a squishy's actual properties.
Check the quantities against the actual offer, keep one score scale, and reconsider any low-confidence input. If the in-game offer changes, update the comparison before making a decision.

Make sure the quantity in Roblox matches what you entered.
If either side changes, stop and rerun the comparison.
A roughly fair ratio is not a command to accept; collection fit and preference still matter.

No. Every item score comes from you, and the result is a decision aid rather than a market price.
A received-to-offered ratio from 0.90 through 1.10 is labeled roughly fair by this site's calculator. That band is a display convention, not an official game rule, live price range, or guarantee. A ratio of 1.00 only means the adjusted totals match on your inputs.
Both start at 0%. You can adjust each from 0% to 25%, and the exact multipliers remain visible in the formula.
