Introduction

The SAB Trade Calculator adds up both sides of a Steal a Brainrot trade using values you choose, and shows which side is bigger and by how much. Steal a Brainrot is a Roblox game where you buy a brainrot, steal brainrots from other players and generate money.1

Give each brainrot the value you put on it, in one unit for both sides, such as in-game cash or your own points. The tool totals each side, works out the difference and the percentage, and shows the working.

How to Use Our SAB Trade Calculator

You Give: Add each item you would hand over. Type its name, how many, and the value you give one of it. Press Add an item for another line.

You Get: Add each item the other player would give you in the same way.

Value each: Use one unit on both sides, such as in-game cash or your own points.

Calculate: See the total for each side, the difference, and the difference as a percentage of what you give, with the working. Reset clears both sides.

Reading the Result

Each side's total is quantity times value, added up over its lines. The difference is what you get minus what you give, so a positive number means you get more by your own values. The percentage compares that difference with what you give: giving 150 for 160 is a 6.7% gain. The bar shows each side's share of the two totals together.

The result is only as good as the values you enter. Two players can put different values on the same item, and the tool shows how the trade looks by yours.

Side total
T = \sum_{i=1}^{n} q_i \times v_i

\text{Difference \%} = \frac{\Delta}{T_{\text{give}}} \times 100
Share of the combined value
S_{\text{give}} = \frac{T_{\text{give}}}{T_{\text{give}} + T_{\text{get}}} \times 100
