Pet Simulator 99 trade calculator
Stack pets on each side and see the verdict, demand-weighted. These are figures from the list's first publication in June 2026 that an August re-check could not two-source-verify, so read a close call here as no call at all.
How the Pet Simulator 99 trade calculator works
Each side's value is the sum of its pets in Diamonds. The verdict isn't just which total is bigger — it's demand-weighted, so a high-demand item counts a little more than its sticker value and a low-demand one counts a little less. That's because demand is what decides whether a trade actually closes at list, and a fair-on-paper trade that hands you something nobody wants is not really fair. The numbers come from the Pet Simulator 99 value list — Huge vs Titanic pets explains the tier gap that drives most of these trades.
Read this before you trust the verdict
The Pet Simulator 99 numbers are the oldest on this site. They were set when the list was first published in June 2026, and a re-check on 16 August 2026 could not two-source-verify them — the live trackers were either unreachable or covering a newer roster — so they were held unchanged rather than refreshed with a guess. The calculator still weighs both sides honestly against each other, but it is weighing May figures against May figures. A close verdict here is not a verdict; treat it as a starting point and confirm the current rate in a live trading hub.
The other adjustment the totals cannot make is liquidity. Titanics carry the higher numbers, but they sit in a thin pool: fewer owners, fewer buyers who can cover one, bigger swings. A Huge at the same value moves faster and closer to list. Trading up into a Titanic can be worth full value on paper and still be the worse trade, because you may hold it a long time before anyone takes it back off you at that number — huge vs titanic pets lays out the comparison.
Reading the verdict
"Fair trade" means the demand-weighted gap is small. "You win" or "you lose" means one side is meaningfully ahead. The sub-line shows the adjusted gap as a percentage of the average, so you can tell a rounding-error difference from a real one. For the underlying numbers, see the Pet Simulator 99 value list.
FAQ
Are these Pet Simulator 99 trade values official?
No. Roblox publishes no trade data. These are community estimates with a date attached, and demand can move the real rate around them.
Why is my "fair" trade marked as a loss?
Because the calculator weighs demand. If your side is full of low-demand items, they total to list value but are harder to trade, so the demand-weighted verdict leans against you even when the raw totals match.
How current are these Pet Simulator 99 values?
They date from the list's first publication in June 2026. A re-check on 16 August 2026 could not two-source-verify them, so they were held rather than refreshed with a guess. They are the oldest numbers on this site and are labelled as dated on the value list too.
Can I share a trade scenario?
Yes. Build the trade, then use "Copy share link" — the URL encodes both sides so anyone who opens it sees the same trade.
