Steal a Brainrot has grown into one of the biggest meme-fueled economies on Roblox, with well over 470 collectible Brainrots spread across eight rarity tiers and a fresh wave of new characters dropping almost every Saturday. With that much variety comes an obvious problem: figuring out what any given Brainrot is actually worth. There’s no official price tag anywhere in the game — value is entirely community-driven, built from thousands of trades and constant debate over how many mid-tier Brainrots it takes to match one genuine heavy-hitter.
It gets more complicated once traits and mutations enter the picture. Two copies of the exact same Brainrot can produce wildly different income depending on what’s rolled onto them, which means trading blind is one of the fastest ways to walk away with far less than you gave up. This is exactly the gap a Steal a Brainrot trading calculator is built to close — instead of guessing or trusting a stranger’s word, you can check both sides of a deal in seconds and see where it actually lands before you commit anything through the in-game Trade Machine.
Steal a Brainrot Trading Calculator
Our calculator combines rarity, income per second, trait, and mutation data into a single lookup so you can compare any two Brainrots — or a full multi-item offer — without digging through Discord price checks or outdated spreadsheets. Since new Brainrots, traits, and mutations ship almost weekly, a tool that updates regularly will always beat a static value list someone posted a few updates ago.
How To Use The Trading Calculator
- Select your Brainrot. Search by name to pull up its base rarity and default income.
- Add its trait, if any. Traits are fixed to specific Brainrots from birth and multiply income on their own — leaving this out is the single biggest reason a calculated value comes out wrong.
- Add its mutation. Mutations are rolled separately from traits and stack with them, so a Brainrot’s real value depends on both layers together, not just its base rarity.
- Compare both sides of the trade. Enter everything being offered and everything you’d receive.
- Check your result. The calculator shows whether the deal favors you, favors the other player, or lands close enough to call it fair.
How Does Trading Work in Steal a Brainrot?
Trading hasn’t always been safe in this game. Before February 22, 2026, there was no official trading system at all players coordinated deals over Discord and then tried to simultaneously steal each other’s Brainrots on a shared private server, hoping the other side actually followed through. It didn’t always work out that way; a common scam involved one player grabbing the agreed-upon Brainrot and immediately locking their base, walking away with both sides of the deal.
That changed with the Trade Machine, a dedicated device placed near the red carpet area in the lobby, close to the Divine Spin wheel and the main conveyor belt. It enforces mutual confirmation on both sides, so nothing changes hands until both players actively agree — which finally made peer-to-peer trading genuinely safe. New accounts on beginner servers won’t have access to it right away; you’ll need to progress into a regular server first before the Trade Machine appears.
Beyond the core Trade Machine, the game has continued layering on new trading options. Base Trading, added in the Summer Update (June 2026), lets players exchange seasonal base skins separately from Brainrots entirely. There’s also an ongoing community discussion, first put to a developer poll in May 2026, about adding Trade Tokens — a proposed currency pegged 1:1 to Robux that would let players sell Brainrots for tokens and buy others without needing to find a matching trade partner directly. As of this writing that remains a community-voted proposal rather than a confirmed live feature, so treat it as something to watch rather than something you can use today.
How To Trade Using The Trade Machine
- Walk up to the Trade Machine near the red carpet and press E to interact with it.
- Choose who you’re trading with A friend, another player currently in your server, or anyone globally by searching their username.
- Select the Brainrots you want to offer, then click Ready once you’re satisfied.
- Wait for the other player to select their side and mark themselves Ready too.
- Confirm together. The trade only completes once both sides have accepted — nothing is exchanged before that.
What Determines a Brainrot’s Value?
There’s no built-in value list every number you see on a calculator or fan site comes from tracked trades, Trade Plaza data, and ongoing community consensus. A few layered factors decide that number.
Rarity Tiers
Steal a Brainrot currently runs eight rarity tiers: Common, Rare, Epic, Legendary, Mythic, Brainrot God, Secret, and OG, with a small Misc category for special event units. Secret is by far the largest top-standard tier, holding hundreds of the game’s Brainrots, while OG sits in a category of its own a tiny handful of original, anniversary, or otherwise irreplaceable units that routinely out-earn even the strongest Secrets.
| Rarity | General Value Impact |
| Common | Very Low |
| Rare | Low |
| Epic | Low–Medium |
| Legendary | Medium–High |
| Mythic | High |
| Brainrot God | Very High |
| Secret | Very High |
| OG | Extreme |
Higher rarity generally means a lower spawn chance and a steeper Dealer or shop cost, which pushes both income and trade demand up. Since the Summer Update Part 2 (June 20, 2026), the game also tracks official exist counts, viewable through the in-game Index and at the Trade Plaza genuinely useful for judging scarcity instead of relying purely on rarity labels.
Traits Explained
Traits are passive income multipliers that come tied to specific Brainrots from the moment you get them unlike mutations, they aren’t rolled or rerolled, and a Brainrot can carry more than one at once. With close to 60 traits now on record, some are dramatically stronger than others.
| Trait | Multiplier | Notes |
| Strawberry | ~9x | One of the strongest traits currently in the game |
| Meowl | ~8x | Tied to a small pool of high-tier Brainrots |
| Pink Egg | ~7.5x | Shares its multiplier with John Pork |
| John Pork | ~7.5x | Shares its multiplier with Pink Egg |
| “26” | ~6x | Event-tied, obtained during the 26 Event |
| Raining Tacos | ~3x | Event-tied, obtained during the Taco event |
| Bloodmoon | ~2x | Event-tied, obtained during the Bloodmoon Event |
| Galactic / Tralalero | Not publicly fixed | Among the rarest traits, locked to a small subset of Legendary and Mythic Brainrots |
Because traits stack with mutations rather than replacing them, a Brainrot carrying both a strong trait and a strong mutation earns dramatically more than either boost applied on its own — which is exactly why endgame trade value clusters around Brainrots with both, not just a rare base unit on its own.
Mutations Explained
Mutations are rolled separately from traits, usually through a spinner or a small chance on the conveyor belt, and only one can be active on a Brainrot at a time. The current mutation pool spans 14 tiers per the Steal a Brainrot Wiki, and the ceiling has climbed steadily as new updates ship.
| Mutation | Multiplier | How It’s Obtained |
| Default | 1x | Baseline — every Brainrot starts here |
| Gold | 1.25x | Small random chance on the conveyor belt |
| Diamond | 1.5x | Small random chance on the conveyor belt |
| Bloodrot | 2x | Bloodmoon Event |
| Candy | 4x | Candy Mutation Event |
| Celestial | 4x | Special celestial events |
| Lava | 6x | Molten Events (recurring, roughly every few hours) |
| Galaxy | 7x | Event-exclusive |
| Yin Yang | 7.5x | Event-exclusive |
| Radioactive | 8.5x | Event-exclusive |
| Cursed | 9x | Event-exclusive |
| Rainbow | 10x | The strongest mutation that occurs naturally without an event |
| Divine | 10x | Event-exclusive; matches Rainbow’s multiplier but adds a chance at the exclusive Halo trait |
| Cyber | 11x | Introduced in Update 47 (April 18, 2026) during the Cyber Event |
| Phantom | 12x | Introduced in Update 53 (June 13, 2026); currently the strongest mutation in the game |
The gap between the bottom and top of this table is enormous — the jump from an unmutated Brainrot to one carrying Phantom is a full 12x income difference before a single trait even enters the picture. This is precisely why checking mutation status isn’t optional when evaluating a trade: rarity sets the ceiling, but mutation decides how close to that ceiling a specific Brainrot actually sits.
Stacking Traits and Mutations Together
The real endgame math comes from combining both systems on the same Brainrot. A God-tier or Secret-tier unit carrying both a top mutation like Phantom or Cyber and a strong trait like Strawberry or Meowl can out-earn — and out-trade — several unmutated, traitless Brainrots of a nominally higher rarity combined. This is the single most common mistake in casual trading: comparing two Brainrots by rarity alone while ignoring that one is running a fully stacked loadout and the other is running none at all.
There’s some debate in the community over the exact math behind stacking — whether multipliers combine multiplicatively or through a different weighted formula — but the practical takeaway holds either way: always check full loadout, not just base rarity, before valuing anything in a trade.
Income Per Second & Exist Count
Two extra numbers matter beyond rarity, trait, and mutation: how much cash a Brainrot generates per second, and how many copies currently exist. The top OG-tier Brainrots post genuinely enormous income figures — the game’s most famous OG unit is widely cited around $750M per second, and one anniversary-exclusive OG Brainrot reportedly earns roughly $1B every second. Even top Secret-tier Brainrots, despite sitting near the top of the standard rarity ladder, typically produce a small fraction of that. This is exactly why OG-tier units command such outsized trade value even when a Secret technically has a “higher” nominal tier name.
Steal a Brainrot Value Tiers: Notable Brainrots
Trade value below reflects general community tiering and shifts constantly — always confirm the live number with the calculator before finalizing anything, especially right after a Saturday update.
| Tier | Notable Brainrots | Trade Value | Demand |
| OG | Strawberry Elephant, Spyder Elephant | Extreme | Extreme |
| Secret (Top) | Headless Horseman, Meowl, Abyssaloco | Very High | Very High |
| Secret / Brainrot God (Upper) | Signore Carapace, Elefanto Frigo, Ketupat Bros | High | High |
| Legendary | Ballerina Cappuccina, Buho de Fuego | Medium–High | Medium–High |
| Mid Tiers | Agarrini la Palini, Bombardini Tortinii, Buho de Noelo | Medium | Medium |
| Lower Tiers | Trenostruzzo Turbo 3000, Divino Platypio | Low–Medium | Low–Medium |
| Common (Starter) | Noobini Pizzanini, Tim Cheese | Very Low | Very Low |
Strawberry Elephant is consistently cited across the community as the single most sought-after Brainrot in the game, both for its enormous income and its status as one of the vanishingly rare OG-tier units. Anything in the OG or top-Secret bracket almost never moves in a simple one-for-one trade — these anchor larger, multi-item deals instead.
How to Check If A Trade Is Fair?
Once both sides are entered into a calculator, the result generally falls into one of three outcomes: you’re winning the trade (receiving more total value than you’re giving up), it’s fair (both sides land close enough to call it even), or you’re losing the trade (giving up more than you receive).
Example: You offer two mid-tier Mythic Brainrots with no mutations. You receive a single Legendary Brainrot carrying a high-multiplier mutation. Depending on the exact rarity and mutation strength involved, that single mutated Legendary can easily outweigh two unmutated Mythics — a reminder that mutation status regularly overrides raw rarity count in real trades.
Always double-check trait and mutation status on every item before confirming through the Trade Machine — a Brainrot’s name alone tells you far less than its full loadout does.
Los Traders & Base Trading: Newer Ways To Trade
Trading in Steal a Brainrot keeps expanding beyond the original Trade Machine. Los Traders, added in a recent update, are a set of three purple NPC traders who let you exchange certain Brainrots directly for better-quality ones tied to a specific new roster — a structured alternative to finding a willing player for every deal. Base Trading, introduced during the Summer Update, works entirely separately from Brainrot trading, letting players exchange seasonal base skins with each other instead of characters.
Neither of these replaces the core Trade Machine for standard Brainrot-to-Brainrot trades, but both are worth knowing about — Los Traders in particular is a legitimate route to upgrade quality without needing to negotiate with another player at all.
Steal a Brainrot Update Timeline: Why Values Keep Shifting
Nothing reshapes the trading market faster than the weekly update cycle. A handful of recent updates show exactly how much a single Saturday can change.
| Update | Date | Trading Impact |
| Update 47 | April 18, 2026 | Cyber Craft Machine added, fusing high-rarity Brainrots into new Secret-tier units and introducing the 11x Cyber mutation |
| Update 51 | May 16, 2026 | 1 Year Anniversary event; added the limited 1 Year trait and 5 new Brainrots, including the OG-rarity Spyder Elephant |
| Update 53 | June 13, 2026 | Summer Update Part 1 — added Base Trading, the 12x Phantom mutation, and 20 limited summer Brainrots |
| Summer Update Part 2 | June 20, 2026 | Added official exist counts, viewable through the Index and the Trade Plaza |
| Update 57 | July 11, 2026 | Added Los Traders — three NPC traders — alongside 6 new Los Brainrots |
Two patterns stand out here. First, nearly every mutation ceiling increase (Cyber, then Phantom) immediately reshuffled what “top-tier value” meant, since a mid-tier Brainrot with the new mutation could suddenly out-earn a rarer Brainrot without one. Second, fusion mechanics like the Cyber Craft Machine actively shrink the exist count of the Brainrots used to create new units — which tightens supply on those older Brainrots and often pushes their trade value up rather than down, even though they didn’t change at all. On top of both, community trading trends move faster than any static list — a Brainrot suddenly favored for a specific Index or event challenge can spike in demand within days, which a regularly updated calculator catches far better than a value list from a few updates back.
Rebirth and How It Changes What’s Worth Trading
Rebirthing resets your progress in exchange for permanently better stats and bonus currency, and it directly affects what’s worth chasing in a trade. Early in a rebirth cycle, players are typically looking for cheap, efficient Common and Rare Brainrots to rebuild income quickly — which temporarily raises demand (and trade value) for low-tier units that would otherwise be nearly worthless. Later in the same cycle, once income is re-established, demand shifts hard back toward Mythic, Brainrot God, and Secret-tier units with strong mutations.
This is worth knowing specifically because it means “trade value” isn’t just a function of rarity and mutation in isolation — it also depends on where the broader player base currently sits in the rebirth cycle. A Common Brainrot that’s nearly unsellable most of the time can briefly see real demand right after a major rebirth-focused update.
Common Steal a Brainrot Trading Terms
New traders run into this shorthand constantly across trading Discords and the Trade Plaza. Here’s what the core terms actually mean.
| Term | Meaning |
| OG | The game’s rarest tier — a small handful of original or anniversary-exclusive Brainrots that out-earn even top Secrets |
| Exist Count | The official number of copies of a specific Brainrot currently in the game, viewable in the Index and Trade Plaza |
| Trait | A fixed income multiplier tied to a specific Brainrot from the start; multiple can stack |
| Mutation | A rolled, mutually-exclusive income multiplier layered on top of a Brainrot’s base and trait income |
| Trade Plaza | The in-game hub showing exist counts and trading data |
| Los Traders | NPC traders who exchange certain Brainrots for better-quality ones without needing another player |
| Rebirth | Resetting your progress for permanently better stats and bonus currency |
| Fusion | Combining high-rarity Brainrots (via machines like the Cyber Craft Machine) into new, rarer units |
Stick to the official Trade Machine for every deal — it’s specifically built to prevent the steal-and-vanish scam that defined the game before February 2026, and there’s no good reason to trade any other way for standard exchanges. Be cautious of any offer that pushes you toward a private server “simultaneous steal” arrangement instead of the Trade Machine; this is the exact pre-2026 method that was replaced because of how easily it could be abused. Real-money deals for Brainrots do circulate in the community, but they carry real added risk — there’s no built-in protection once money changes hands outside Roblox’s own systems, and no guarantee the other side follows through. The safest approach is to keep trades inside the Trade Machine and treat any deal that tries to move off-platform with real caution.
Best Brainrots To Trade For
Highest Value Picks
OG-tier units like Strawberry Elephant and Spyder Elephant represent the absolute ceiling of the current market, alongside top Secret-tier names like Headless Horseman and Meowl. These are rarely simple one-for-one trades and usually anchor much larger deals.
Best Picks For Active Players
Legendary-tier Brainrots like Ballerina Cappuccina are widely recommended as realistic targets for most actively playing accounts — strong enough to matter, without requiring an already-stacked inventory to trade for.
Rising Demand
Watch for Brainrots tied to whatever the current seasonal Index or event challenge is — units needed to complete a limited-time collection routinely see short-term demand spikes well beyond their normal trade tier.
Steal a Brainrot Trading Tips For Beginners
Never trade without checking both rarity and mutation status first — a bare rarity comparison misses the exact detail most likely to make a deal lopsided. Avoid rushing into a trade just to secure a specific Brainrot quickly; the same unit will almost always come back around if you’re patient. Stick to the Trade Machine exclusively rather than reverting to older, riskier trading methods, even if someone insists it’s faster. Compare trait strength alongside mutation, not just one or the other, since both stack together into a Brainrot’s real earning power. And treat any real-money offer with extra scrutiny, since it sits outside the protection the Trade Machine was specifically built to provide.
Trading Calculator vs. Manual Checking
| Method | Speed | Accuracy |
| Manual checking | Slow | Medium |
| Calculator | Fast | High |
Manually cross-referencing Discord price checks and older tier lists can technically work, but it’s slow and easy to get wrong right after a Saturday update reshuffles the meta. A regularly updated calculator accounts for trait and mutation stacking automatically and gives you a consistent verdict in seconds — exactly when you need it, with a trade partner waiting on your response.
