A trade calculator compares the total value of what you give vs. what you receive. Open the SAB Trade Calculator, add your brainrots on the left, theirs on the right, set the exact mutation and traits for each (this is where most people go wrong), and read the verdict: Win, Fair, Slight Loss or Bad Trade. Never accept a trade the calculator flags as a loss without a reason you can articulate.
Step by step
1. Add each brainrot you're giving to "Your Offer" — search by name, then select the mutation from the dropdown. 2. Add every trait the brainrot carries; a Divine with two traits is worth meaningfully more than a bare Divine. 3. Repeat for "Their Offer". 4. Read the bar and verdict. 5. Tap "Why this value?" to see exactly what drives each side — mutation premiums, exist counts, trait bonuses. If a number surprises you, that panel explains it.
The mistakes that skew results
The most common error is forgetting the mutation — comparing a Default Meowl against what is actually a Diamond Meowl completely flips a verdict. Second: ignoring the Taco question. In the current meta a Taco trait loses roughly 70% of its value if the buyer doesn't want it, so our calculator explicitly asks whether the buyer likes Taco. Third: quantity — three cheap brainrots stacked can quietly out-value one expensive one, which is exactly the structure lowballs exploit.
Reading verdicts like a trader
Verdicts adapt to trade size: small trades use tight tolerances, big trades allow more negotiation room. A "Slight loss" on a small trade is a real loss; on a huge trade it may be within normal market noise. And remember calculators are references, not oracles — live demand always has the final word. If someone is desperately hunting the exact variant you own, you can close above calculator value with confidence.
FAQ
Is the SAB trade calculator accurate?
It gives a strong estimate based on community market values, exist counts, mutations and traits — but real value always depends on live demand. Use it as a floor for negotiations, not an absolute truth.
Does the calculator account for traits?
Yes — each trait adds a percentage bonus, with streak bonuses for multiple traits and an anti-spike cap. The Taco trait has a special toggle because it can lose ~70% value if the buyer doesn't want it.
What does the "Why this value?" panel show?
It breaks down every factor driving each side: mutation premiums, income bracket, exist count scarcity and high-value traits — so you understand the verdict, not just see it.
