Introduction

The Steal A Brainrot Value Calculator helps you figure out what your brainrots are worth and whether a trade is fair. If you play Steal A Brainrot on Roblox, you know how hard it can be to tell if someone is offering you a good deal or ripping you off. This tool does the math for you. If you also trade items on the Roblox marketplace, our Roblox Tax Calculator can help you figure out how much Robux you keep after fees.

Use the Trade Checker to add brainrots to each side of a trade and instantly see who gets the better deal. Pick mutations like Shiny, Gold, or Galaxy to see how they change the value. The calculator shows you a step-by-step breakdown so you understand exactly how the numbers work.

You can also use the Price Lookup to search for any brainrot and check its current value, rarity, demand, base income, and mutation modifiers. Or browse the full Value List to sort and filter all 420+ brainrots by value, rarity, demand, or income.

Stop guessing. Use this calculator before your next trade so you never overpay again.

How to Use Our Steal A Brainrot Value Calculator

This calculator helps you check if a trade is fair in Steal A Brainrot. Pick the brainrots each side is offering, and the tool tells you who gets the better deal. You can also look up any brainrot's value or browse the full value list.

Trade Checker

Click "Add Brainrot" on the Your Offer side to search for and add the items you plan to give. You can add up to 8 brainrots.

Click "Add Brainrot" on the Their Offer side to add the items the other player is giving you. You can add up to 8 brainrots here too.

Pick a mutation from the dropdown under any item if that brainrot has a mutation like Shiny, Gold, or Rainbow. This changes its value. Since mutations apply a percentage increase to the base price, knowing the exact modifier matters.

Press the Calculate button to see the trade verdict. It shows the total value of each side, a fairness bar, and whether you are overpaying or getting a good deal.

Press Reset to clear both sides and start a new trade check.

Type a brainrot name in the search box to find it. Click on the result to see its full stats, including its current value, rarity, base income per second, demand level, trend, and all mutation price boosts.

Value List

Use the Search box to filter brainrots by name.

Use the Rarity dropdown to show only Common, Uncommon, Rare, Epic, Legendary, Secret, or OG brainrots.

What Is Steal A Brainrot?

Steal A Brainrot is a popular Roblox game where you collect funny internet meme characters called brainrots. These brainrots have silly names like Tralalero Tralala, Bombardiro Crocodilo, and Tung Tung Tung Sahur. The goal is to steal brainrots, grow your collection, and trade with other players to get the rarest ones. If you are a Roblox developer earning Robux from your own game, you can use the Roblox DevEx Calculator to estimate how much real money your Robux convert to.

How Brainrot Values and Trading Work

Every brainrot in the game has a market value. This value tells you how much a brainrot is worth compared to others. When you trade with another player, you want to make sure the items you give away are worth about the same as the items you get back. If you give away more value than you receive, you overpay. If you receive more value, you get the better deal. The trade checker uses a percent difference calculation to determine how far apart the two sides are.

Rarity, Demand, and Mutations

Each brainrot has a rarity tier: Common, Uncommon, Rare, Epic, Legendary, Secret, or OG. Higher rarity usually means higher value. Brainrots also have a demand level — high, medium, or low. A brainrot with high demand is easier to trade because more players want it.

Mutations are special versions of a brainrot, like Shiny, Gold, Rainbow, or Galaxy. A mutation adds a percentage boost to the brainrot's base value. For example, a Galaxy mutation adds +150% to the value, making the brainrot worth 2.5 times its normal price. Always check if a brainrot has a mutation before you accept a trade.

What Does Base Income Mean?

Each brainrot earns you in-game currency every second. This is called base income per second. Rarer brainrots earn more income. This helps you save up and grow your collection faster over time.
