Is this an official calculator?

No. It is an independent player-input calculator and does not use an official Roblox formula.

How do I measure bananas per minute?

Record your starting count, play a normal route for 60 seconds, and subtract the start from the end.

Why does the estimate change?

Your route, upgrades, trainer, multiplier, lag, target availability, or a game update can change the measured rate.

What is upgrade break-even?

It is the entered cost divided by the improvement between your measured new and old rates when that improvement is positive.
