About the numbers
The values are RAP (recent average price) in diamonds for the Normal version of each pet, written on a K, M, B and T scale, for example 662B for Titanic Hippomelon. We compared four public PS99 price trackers (PS99RAP, PetSim99, Pet99Prices and PetSimXValues, all checked 15 October 2026) and kept the median only when at least two agreed within about 15%. Pets with fewer than two readings are not listed. All four trackers read the same public game data feed, so they confirm each other's freshness but are not fully independent.
RAP is an average of past sales, not an official price. Pets with few copies in existence can sell far above or below RAP, and Golden, Rainbow and Shiny versions are worth much more and are not included. The eight-slot limit is our own: the Pet Simulator Wiki does not state a trade size limit. Pet names and icons come from the Pet Simulator Fandom wiki, whose image pages show no license, so the icons are game art by BIG Games. Not affiliated with Roblox or BIG Games.

Frequently asked questions
How does the Pet Simulator 99 trade calculator work?
You choose pets for each side. It adds up their RAP values in diamonds and compares the totals. If what you get is at least 5% higher it shows Win, if it is at least 5% lower it shows Loss, and otherwise Fair.
Where do the pet values come from?
From the median of four public price trackers we checked on 15 October 2026. A pet is only listed when at least two readings agree within about 15%.
What is RAP and what unit is it in?
RAP is the recent average price of a pet, based on past sales. In this calculator it is counted in diamonds and refers to the Normal version of the pet.
Are Golden, Rainbow and Shiny pets included?
No. Only Normal versions are listed. Other versions are worth much more, so do not use this calculator for them.
Why is a pet I trade missing?
We list 41 popular Huge and Titanic pets. Pets with fewer than two matching price readings, such as brand new ones with no RAP yet, are left out on purpose.
