How do the entered income subtotals differ?
For every valid row, the tool multiplies entered income per second per unit by quantity and an optional multiplier, then sums each side. It does not assign item prices or score the trade.

Enter both offers as item rows and compare their displayed income contribution. This is arithmetic support, not an appraisal or recommendation.

Compare two offers by entered income only
Add the rows you can verify in-game. Names, quantities, income rates, multipliers, and notes are supplied by you; this site has no item-price or demand dataset.
Income comparison is not a fair-value appraisal. The result does not assess rarity, demand, availability, restrictions, or transfer safety.

Income comparison is not a fair-value appraisal.
Before confirming in-game
- Confirm names, quantities, displayed income, and any visible multiplier on both sides.
- Treat free-text names and notes as your own observations; they are not verified by the calculator.
- Check the in-game confirmation screen yourself. The subtotal cannot account for rarity, availability, preferences, rules, or transfer behavior.
Trade calculator questions
Is this an official Brainrot Laboratory value calculator?
No. It is an independent income-only worksheet. It has no official or community-authoritative item-price dataset.
Why does the result only compare entered income?
Displayed income cannot establish rarity, demand, availability, restrictions, transfer rules, or a market valuation.
Where do the item names and numbers come from?
Every row is player-entered. Names and notes do not affect the math; quantity, displayed income, and an optional multiplier determine each row subtotal.
What happens when a side is empty or a number is zero?
A one-side entry returns only that side's subtotal. Zero income is valid, and a ratio with a zero denominator is shown as unavailable rather than Infinity.
