Brainrots in Steal a Brainrot are sorted into rarities, and the rarity tells you two things at once: how much a brainrot earns per second and how much it costs on the conveyor. The numbers below come from the brainrot entries in the site database, which follow the Steal a Brainrot Wiki. They cover base income and base cost, before any mutation or trait is applied.
The database holds 603 brainrot entries, and 395 of them are flagged as currently obtainable. All the figures here use only the obtainable ones, so retired brainrots do not distort the ranges.
Rarities from lowest to highest
| Rarity | Obtainable entries | Income per second | Cost | Median payback |
|---|---|---|---|---|
| Common | 8 | $1 to $14 | $25 to $1.7K | about 111 s |
| Rare | 8 | $15 to $72 | $2K to $9.6K | about 133 s |
| Epic | 14 | $75 to $275 | $10K to $42.5K | about 160 s |
| Legendary | 19 | $200 to $5.2M | $35K to $15M | about 241 s |
| Mythic | 26 | $2.1K to $18.7K | $400K to $6.2M | about 317 s |
| God | 67 | $20K to $324K | $7.5M to $78.5M | about 193 s |
| Secret | 222 | $325K to $425M | $715 to $425B | about 233 s |
| OG | 6 | $450M to $1B | $450B to $1T | 1,000 s |
"Median payback" is cost divided by base income: how many seconds a brainrot needs to earn back its own price with no mutation. It is a rough comparison tool, not a promise of what the game pays.
Two entries in the ranges look like data quirks rather than real tiers. Easter Bunny is listed as Legendary at $5.2M per second, far above its neighbours, and one Secret entry is listed at a cost of $715. Treat the ranges as the span of the database, and use the medians for comparisons. The database also keeps a "misc" group of 26 entries for items that do not fit a rarity (lucky blocks and a few special brainrots), of which 15 are obtainable.
What the table shows
Payback does not rise in a straight line. Common to Mythic get slower to repay: 111 seconds, 133, 160, 241 and 317. God breaks the pattern at about 193 seconds, which makes it a faster payback than Legendary or Mythic. Secret sits at about 233 seconds, close to Legendary. If your goal is the shortest time to recover what you spend, God brainrots are the efficient middle step.
OG is deliberately expensive. Every OG brainrot costs exactly 1,000 times its income, so each takes 1,000 seconds to repay. What you buy is raw income, since the weakest OG still earns $450M per second. The six obtainable OG brainrots are:
| OG brainrot | Income | Cost |
|---|---|---|
| Spyder Elephant | $1B/s | $1T |
| Strawberry Elephant | $750M/s | $750B |
| Meowl | $600M/s | $600B |
| Headless Horseman | $550M/s | $550B |
| John Pork | $500M/s | $500B |
| Skibidi Toilet | $450M/s | $450B |
The Spyder Elephant guide and the Strawberry Elephant guide cover how to get the top two.
Examples from each rarity
| Rarity | Highest income examples | Cheapest examples |
|---|---|---|
| Common | Holy Arepa ($14/s), Pipi Kiwi ($13/s) | Noobini Pizzanini ($25), Lirili Larila ($75) |
| Rare | Pengolino Nuvoletto ($72/s), Tric Trac Baraboom ($65/s) | Trippi Troppi ($2K), Gangster Footera ($4K) |
| Epic | Wombo Rollo ($275/s), Gato Celesto ($250/s) | Cappuccino Assassino ($10K), Brr Brr Patapim ($15K) |
| Legendary | Seraphino Gruyero ($1.9K/s), Electro Quacko ($1.8K/s) | Burbaloni Loliloli ($35K), Chimpanzini Bananini ($50K) |
| Mythic | Tic Tic Ribbit ($18.7K/s), Orbi Mochi ($18.5K/s) | Orangutini Ananassini ($400K), Rhino Toasterino ($450K) |
| God | Mortaruga ($324K/s), Candi Corni ($321K/s) | Gattatino Nyanino ($7.5M), Girafa Celestre ($7.5M) |
| Secret | Los Dragons ($425M/s), Phoenix ($425M/s) | Blackhole Goat ($75M) and up |
Legendary examples exclude the Easter Bunny outlier, and Secret's cheapest example leaves out the $715 entry.
Worked comparisons
Payback is simply cost divided by income, so you can check any brainrot yourself.
| Brainrot | Rarity | Cost / income | Payback |
|---|---|---|---|
| Wombo Rollo | Epic | $42,500 / $275 | about 155 s |
| Mortaruga | God | $78.5M / $324K | about 242 s |
| Tic Tic Ribbit | Mythic | $6.2M / $18.7K | about 332 s |
| Los Dragons | Secret | $425B / $425M | 1,000 s |
| Strawberry Elephant | OG | $750B / $750M | 1,000 s |
The top Secret brainrots share the OG ratio: Los Dragons also costs exactly 1,000 times its income. That means the very top of Secret and the whole OG tier are priced on the same curve, and the difference between them is how much income you are buying, not how fast it repays.
A mutation multiplies the income side. Mortaruga at $324K per second with a x14 mutation would earn about $4.5M per second, which is more than every Legendary entry in the table except the Easter Bunny outlier. That is why a mid-tier brainrot with a strong mutation can beat a higher rarity without one.
Where each rarity fits in a run
- 1Common to Epic are the starting band. They earn little in absolute terms, but their payback is under three minutes, so they are the quickest way to fill a base early.
- 2Legendary and Mythic are the next purchases. Payback grows past four to five minutes, but income climbs from hundreds to thousands of dollars per second.
- 3God is the efficient middle: a payback near three minutes with six-figure income.
- 4Secret is the largest group in the database (222 obtainable entries) and spans from $325K to $425M per second, so the specific brainrot matters far more than the label. The secret brainrots guide lists how to get them.
- 5OG is a late-game target with fixed prices and the highest base income in the game.
How often each rarity shows up on the Red Carpet is a separate question, covered in the spawn rates guide. For the cheapest way in, see the cheapest brainrots list, and to turn lower rarities into higher ones, see the fuse recipes guide. Every individual brainrot has an entry in the brainrots list, and the brainrot tier list ranks them by value.
Mutations and traits change the picture
All figures above are base values. A mutation or trait multiplies them, and the effect is large: a x14 mutation on a God brainrot changes its income far more than moving up one rarity. The calculator applies the multipliers for you, and the mutations multipliers guide lists them.
Reading the database honestly
The site stores wiki data, and the wiki is edited by players, so a small number of rows may lag behind the game after an update. When a figure matters for a purchase, confirm it on the brainrot's own page or in the game shop before spending.
Common mistakes
- Comparing rarities by price alone. A Secret can cost less than a God and earn far more.
- Assuming a higher rarity always repays faster. Mythic takes longer than God.
- Ignoring base values when a mutation is involved. The mutation multiplies the brainrot, so a strong base still wins.
- Buying an OG too early. Its 1,000-second payback only makes sense with a base that can afford the wait.
- Trusting a single outlier row. A few entries have unusual figures, so compare medians, not the highest or lowest value.
