Every upgrade will ultimately pay for itself, but some upgrades pay for themselves faster.

This table shows the efficiency of the upgrade itself in the first row of each cell and the efficiency of the tower including that upgrade in the second row. The efficiency is how many rounds it will take until the tower pays for itself. In short, the lower the numbers are, the better.

Please note that the left side gives lives per round and lives per ability use that have their own efficiency (dollars per life per round/use; smaller is better); the right side can pay for itself over time alongside normal banana income, 4R+ can also pay for itself with an amount of lives lost, and 5R can pay for itself with ability activations. Infinity symbols (∞) in the first rows are because that upgrade does nothing to improve that aspect of the tower.

  • Bananas never expire, and can stay on-screen indefinitely.
  • Bananas auto-collect when a high number of them are on-screen.
  • Passive Income provides a constant stream of income that can generate lots of additional income for a small cost during longer rounds.
  • Rubberfruit farms can be used to regrow farm even without Regrow bloons.
  • While expensive, the 5S ability is extremely powerful and an excellent late game tool for wasting excess cash.



  • After enough rounds have passed, it earns you significantly more than it cost.
  • Can give extra lives.


  • Cannot attack bloons, except with the 5S ability, which costs a hefty amount of money to use.
  • Banana generation becomes ineffective during longer rounds in freeplay.

Known Bugs

  • Sometimes, only the farms which are upgraded at last round will produce bananas.
  • Farms sometimes do not produce the correct amount of bananas.
