Monkey Bank, also known as Bank, is the Banana Farm's path 2 tier 3 upgrade in Bloons TD 6. Instead of producing bananas to collect, during rounds the Monkey Bank adds cash to an internal balance, which not directly available for use but can be withdrawn at any time. During a round, it generates equal-valued cash packets divided from its base income generation. After a round ends, the Monkey Bank increases its balance by 15% in interest. The Monkey Bank has a maximum balance of $7,000 ($9,500 with Bigger Banks Bigger Banks), and when the Monkey Bank is full it will no longer produce any cash in any way until the balance is withdrawn.

The Monkey Bank's base income generation during the round is $180 per round, affected by its own Valuable Bananas upgrade and the More Valuable Bananas More Valuable Bananas MK, which is increased further by Increased Production and Greater Production. The actual cash generation without More Valuable Bananas More Valuable Bananas is, before end-of-round interest, a total of $225 per round (+$50 per Path 1 upgrade), increased to a total of $234 per round (+$52 per Path 1 upgrade) with it.

If crosspathed with EZ Collect, the Bank will visually glow when full, which reminds the player to collect its cash. If crosspathed with Banana Salvage, the Bank autocollects itself at the end of the round when full.

Cash production in Half Cash

In Half Cash, the Monkey Bank's cash production is halved as normal, but its interest is unchanged. Because the Monkey Bank's growth is non-linear, it produces more than half as much cash overall after the first round.

Strategy

This section was last updated for: version 50.2

Monkey Bank is a great farming option if allowed to build interest, and collected when at full or almost full capacity. Under those conditions, it earns much more money than similarly priced farms such as Marketplace and Banana Plantation. To be used optimally, players should keep an eye on their Monkey Banks' balances and remember to withdraw when it's time. The Monkey Bank with Greater Production is greatly improved by   Bigger Banks and   More Valuable Bananas. With those Monkey Knowledge upgrades, the 2-3-0 crosspath generates $9,465 per 11 rounds or about $860 per round on average, over double that of Marketplace.

However, Monkey Bank becomes a poor option if constantly collected too early (not building up much interest), or too late (wasting time while the balance is full). Another downside is that the cash it produces is locked in its balance until withdrawn, as opposed to other farms which let you use the cash right away; this can be a hindrance if the money is urgently needed. Synchronizing multiple Banks and their balances can be convenient, but is not cost-efficient when spamming Banks.

Greater Production is almost always preferred, as it lets the Monkey Bank generate more money. The Banana Salvage upgrade loses out on cash, but will make the Monkey Bank automatically withdraw its balance after it is full; this may be appealing to particularly hands-off players, while still generating more cash on average than a Marketplace.

  •   Upgrade cost increased ― $2,800 → $3,200
  •   Upgrade cost increased ― $3,200 → $3,300
  •   Capacity reduced ― $10,000 → $7,000
    • Note: IMF Loan and Monkey-Nomics capacity is unaffected
  •   Cash produced per round reduced by $10
  •   Description changed ― "Generates money each round and stores it in the bank. Earns 15% interest each round." → "All money generated by this farm is now stored in the bank and earns 15% interest each round."
  • Repositioned the collection buttons
Monkey Bank is just too stonks even without Benjamin. This nerf shouldn’t hurt it too much, but will make it snowball a little bit slower and balance with the other paths better.
— Update notes
  •   Upgrade cost increased ― $3,300 → $3,500
Banana Farm’s xx2 upgrade is the inferior crosspath, so we’ve amped up the utility with the lazy aspect so that if it’s going to be inferior for production, it’s at least going to be extra lazy & less far behind.
— Update notes
  •   Resolved an issue where fractional cash amounts could sometimes round up instead of down (bug fix)
0-3-2
  •   Now autocollects at the end of the round with no delay if capacity is full
Bank is a little too much more efficient than any other Banana Farm option, this price nerf should leave it so it really somewhat still is but not so far ahead.
— Update notes
  •   Upgrade cost increased ― $3,500 → $3,800
For sake of consistency we want Monkey Bank to increase in cash generation when used with sources that externally buff generation so everything works as expected
— Update notes
  •   Now increases in cash generation with external buffs
  •   Income generation now works with More Valuable Bananas monkey knowledge (undocumented)
The current power of xx5 Village combined with previous nerfs to Middle Farm have it currently feeling underappreciated for farm profits, some slight price adjustment.
— Update notes
  •   Upgrade cost reduced ― $3,800 → $3,650
  •   Glow indicator of full banks works without 0-X-1 crosspath (bug)
  •   No longer glows when full without the X-X-1 EZ Collect crosspath (bug fix)
