Steal a Brainrot Calculator

About the Steal a Brainrot calculator

This unofficial Steal a Brainrot calculator compares both sides of a trade with community value scores, mutation multipliers, combined trait bonuses, quantity, and estimated income per second. It is designed for quick W/F/L checks, not as an official price list or a guarantee that another player will accept a trade.

The value table is a dated snapshot based on a public community value list. Steal a Brainrot values can change after weekly updates, Admin Abuse events, rarity changes, and shifts in player demand, so always check the last-updated date before relying on a result.

How to use the W/F/L trade checker

1. Add every Brainrot in your offer.
2. Add every Brainrot you would receive.
3. Select the mutation shown on each item.
4. Add the combined trait bonus shown by the item's traits. Enter 0 when it has no traits.
5. Set the correct quantity and compare both value and income totals.
6. Treat a result within 5% as close enough to require a manual demand and rarity check.

How the calculation works

The calculator starts with the item's base community value and, when available, its base income per second. It then applies the selected mutation and the combined trait bonus:

combined multiplier = mutation multiplier + total trait bonus

adjusted value = base value × combined multiplier × quantity

adjusted income = base income × combined multiplier × quantity

For example, a Gold item has a 1.25× mutation multiplier. If its visible traits add another 5×, the combined multiplier is 6.25×. Mutation multipliers and the additive trait model follow the public Steal a Brainrot mutation reference.

The adjusted value formula is a comparison model, not an official market formula. Demand, exist count, limited availability, and rare trait combinations can make the real trade outcome different from the numeric result.

Trade value versus income

Value and income answer different questions:

• Value estimates how the community may compare the items in a player-to-player trade.
• Income estimates how much the items can generate per second with the selected modifiers.

A high-income Brainrot is not always the most desirable trade item. Likewise, an older limited item can retain demand even when a newer Brainrot generates more income. Check both totals and the demand column instead of accepting a trade based on one number.

If an item's income is marked Not tracked, it still contributes to the value total but contributes 0 to the displayed income total.
