All money generated by this farm is now stored in the bank and earns 15% interest every round.
~ BTD6 description


Monkey Bank is the 3rd upgrade on Path 2 for Banana Farm in Bloons TD 6. When a Banana Farm gets upgraded to Monkey Bank, the farm becomes a bank controlled by monkeys. The Monkey Bank no longer drops bananas but instead generates money throughout the round, which is placed in its very own "bank account", separate from that of other Monkey Banks.

It generates $230 per round which can be upgraded to $270 and $310 with the Increased Production and Greater Production upgrades, respectively. It can store up to $7,000 and can be increased to $9,500 with Bigger Banks. At the end of each round, the currently stored balance earns 15% interest. Therefore, a Monkey Bank can produce at least $265 per round at bare minimum when interest is taken into consideration.

Despite Path 3 upgrade crosspaths not seeming to be useful at increasing income, Path 3 upgrade crosspaths have utility usage. Monkey Bank with EZ Collect will highlight itself once it is full, while a Monkey Bank with the Banana Salvage upgrade will autocollect its balance when full after one round.

Unlike BTD5, selling a Monkey Bank will automatically withdraw the balance stored in the bank.

Income earning per round (12.0 and later)Edit

As of Version 12.0, bank income bonus has decreased from +$160 to +$150 by default. Therefore, instead of at least $240 per round, this income gain is decreased to at least $230 per round.

Note: The table assumes that the Monkey Bank has been initially upgraded before the first round starts and that the result is given as when the round has ended. (After interest has been applied)

As of Version 17.0, the buff to Monkey City allowed nearby income-producers, such as Monkey Banks, to gain +10% more income per round. This applies for the income bonus, and it stacks on top of the current interest rate (in addition to interest buffs from Benjamin, if applicable).

As of Version 7.0, bank account capacity is decreased for Monkey Banks, though IMF Loan bank account capacities remained the same.

Income earning per round (pre-7.0)Edit

The following is information regarding income earning per round for the Monkey Bank before the Version 7.0 nerf that lowers the maximum bank capacity. For Version 7.0 and later, the following is still true for IMF Loans' and Monkey-Nomic's bank accounts.

Note: The table assumes that the Monkey Bank has been initially upgraded before the round starts and that the income is given as when after the round.

Note 2: In BTD6 v3.x, the Monkey Bank does not appear to consistently calculate interest correctly for the 0/3/x and 1/3/0 banks. The following results are the maximum of three tests

TriviaEdit

  • On Version 14.0 and later, Monkey Banks and their subsequent upgrades do not make bank collection sounds when collecting their accounts.
    • Interestingly enough, the autocollection from crosspathing with Banana Salvage didn't make an autocollection sound either, even before Version 14.0.
