IMF Loan ability: Gives you $9,000 but you have to pay it back over time.
~ In-game description

IMF Loan is the fourth upgrade of Path 2 for the Banana Farm in Bloons TD 6. In addition to a bigger bank capacity of $10,000 ($12,500 with the BiggerBanksIcon Bigger Banks MK), the IMF Loan has an activated ability where, upon activation, the player is loaned $9,000 ($10,000 with BackroomDealsIcon Backroom Deals), at the cost of accruing debt. When in debt, 50% of the player's earnings go into paying it off gradually (cost of 40% earnings with BackroomDealsIcon Backroom Deals). IMF Loan abilities can still be activated while the player is in debt, but each subsequent IMF Loan ability usage gives only $4,500 usable credit ($6,000 with Backroom Deals) and $4,500 additional debt ($4,000 with Backroom Deals), as 50% (40%) of each subsequent loan goes toward paying off previous loans, and therefore has no effect.

The activated ability has a cooldown time of 90 seconds, and additionally cannot be used until the loan is entirely paid off. Like all income-only abilities, IMF Loan can only be used a limited number of times per round and the ability is unusable after 3 minutes since the start of a round. The ability can only be used up to two times per round per IMF Loan, unless sold and rebought.

IMF Loan's ability is not affected by any income-increasing buffs such as Monkey City.

This upgrade costs $6,120 on Easy, $7,200 on Medium, $7,775 on Hard, and $8,640 on Impoppable.

Description[]

Overview[]

Imf ability default

IMF Loan ability activated. Note the cash gain and the accompanied debt

IMF Loan is a large blue-grey office building with yellow windows and a small entrance flanked by grey stone pillars, with steps leading up to the actual doorway. On the roof is a banana logo attached to a semicircular extension, as well as a small metal chimney.

Top Path crosspathing adds grey/gold stones around the foundation. Bottom Path crosspathing adds wooden, then cyan crates with a banana logo at the front of the building.

The IMF Loan offers greater capability to handle money, from a larger bank account, to the capability to loan a sum of cash at the drawback of debt, and the capability to deposit money (available only via BankDepositsIcon Bank Deposits).

Targeting Priorities[]

IMF Loan, which stores money in its bank account similarly to its preceding upgrade Monkey Bank, does not have a real targeting priority. Instead, it has different buttons that alter its behavior.

IMF Loan comes with two "targeting priorities" by default: Collect, and Collect All. "Collect" withdraws all money from the current IMF Loan, while "Collect All" withdraws all money from all Banks (including IMF Loans) on screen. If the BankDepositsIcon Bank Deposits MK is enabled, IMF Loan also receives the Deposit button, which deposits money into the IMF Loan's bank account.

IMF Loan Ability

Upon activation, the player will receive $9,000 but at the cost of $9,000 debt. The ability will recharge after 90 seconds, but can only be activated again if all of that IMF Loan Bank's debt is paid off. Both the loan and the debt will increase to $10,000 with the BackroomDealsIcon Backroom Deals MK.

How the "debt" works is that 50% of all income gained (40% of all income gain with Backroom Deals) from all sources will be used to pay off the debt. The amount of income used to pay off the debt is paid off onto the first IMF Loan that owes money and then onto any other subsequent in-debt IMF Loans after paying off the first IMF Loan. The in-debt penalty will remain until all of the debt is paid off from all IMF Banks. The amount of debt is displayed to the right of the cash counter on the top of the screen. The amount of debt of a certain IMF Loan Bank is shown in the respective IMF Loan Bank. Note that the player can still sell an IMF Loan Bank while any of the loans are in debt (including itself), but the loan debt will remain until fully paid off. Fortunately, it is impossible to lose as a result of not paying off IMF Loan debts because bankruptcy is not a lose condition.

Unlike normal loans, the player cannot manually pay off the debt of a certain IMF Loan Bank. However the total debt can be paid off quickly by repeatedly depositing and withdrawing from any bank using Bank Deposits.

The ability cannot be used if the player still has debt from the same IMF Loan Bank.

Strategy[]

Summary[]

IMF Loan offers a tricky ability to master, as though its ability explicitly about gaining money in a large burst, it effectively cancels out the profit with the penalty of a loan which halves the gains of all revenue sources (including other IMF Loan abilities) by paying itself off, leading to an ability with zero sum profit if the player does not reinvest the cash.

The IMF Loan provides the player with a powerful utility: instant income for instant purchasing power or reinvestment into more IMF Loans. This is typically great for Ranked Boss, as it can potentially provide the player with extreme amounts of cash by round 40. The downside is that the debt is a significant detriment for later tiers, as income gain is reduced by 40% with BackroomDealsIcon Backroom Deals, 50% without the MK point. This same point also raises the cash gained per loan from $9,000 to $10,000, making the IMF Loan more productive overall.

Another important part of IMF Loan are BankDepositsIcon Bank Deposits via Monkey Knowledge. It allows manual depositing of cash into the IMF Loan, which gains interest after holding the bank deposit for at least 2 rounds. In turn, proper bank deposits maximizes the IMF Loan's income, with constant micromanagement. Such benefit is maximized on Ranked Boss Bloon Events that enable MK. Without this MK, it is not worth using the IMF Loan.

Note that using multiple loans at once will grant $9,000/$10,000 from the first ability, but each subsequent loan will be affected by other loan's debt, granting $4,500 ($6,000 with Backroom Deals) and will only increase the total loan by $4,500 ($6,000 with Backroom Deals) rather than $9,000/10,000, assuming it must pay off maximum debt. This value can be higher if debt is below this.

Only one loan can be paid off at a time, and any large singular sum, primarily selling towers, that exceeds this debt will directly go to the player without paying off additional loans at a 50%/40% rate. This is actually a key strategy in ranked Boss events, and gives more value to very expensive towers, such as Plasma Monkey Fan Club.

Efficiency[]

The following are tables regarding the income production rate of the normal Monkey Bank function of the IMF Loan upgrade. In general, it has a higher bank capacity but a similar income production rate to Monkey Bank. As such, its bank functionality does not become more efficient than Monkey Bank until its own bank balance surpasses the Monkey Bank's maximum bank capacity.

Income earning per round (35.0-Present)[]

Version 35.0 secretly changed the total amount of income per round the income packets generate, in addition to accepting all external buffs that increase income (mainly Monkey City).

Instead of $230/$270/$310 per round, the Bank now produces $225/$274/$325 per round, ignoring the added interest applied afterwards. Also, MoreValuableBananasIcon More Valuable Bananas now increases income generation of each cash packet.

Also assumes that the BiggerBanksIcon Bigger Banks MK is active.

Bank Deposits MK (35.0-Present)[]

Adding Bank Deposits will almost always increase profit per round. However, after some testing and calculating, the most efficient strategy has made itself apparent, To save space in the table, assume that all farms have the 2-4-0 upgrade.

The money is shown as the amount in the bank at the end of the round (after interest has been applied) and as if all deposits happened during the first round.

Calculations about the average profit per round for each scenario have been made. It is concluded it is more efficient to withdraw 1 round before the bank reaches its maximum capacity. Otherwise, the last interest payment is reduced due to the account balance hitting its cap of $12,500. The profit per round can be calculated by subtracting the amount deposited from the amount of money in the bank, then dividing by the number of rounds before withdrawing.

Income earning per round (12.0-34.3)[]

As of Version 12.0, bank income bonus has decreased from +$160 to +$150 by default, including for IMF Loan. 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 IMF Loan has been initially upgraded before the round starts and that the income is given as when after the round.

Also assume that no manual deposits from the Bank Deposits MK are done.

As of Version 17.0, the buff to Monkey City allowed nearby income-producers, such as IMF Loans, 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).

Bank Deposits MK (19.0 onwards)[]

Adding Bank Deposits will almost always increase profit per round. However, after some testing and calculating, the most efficient strategy has made itself apparent, To save space in the table, assume that all farms have the 2-4-0 upgrade.

The money is shown as the amount in the bank at the end of the round (after interest has been applied) and as if all deposits happened during the first round.

Calculations about the average profit per round for each scenario have been made. It is concluded it is more efficient to withdraw 1 round before the bank reaches its maximum capacity. Otherwise, the last interest payment is reduced due to the account balance hitting its cap of $12,500. The profit per round can be calculated by subtracting the amount deposited from the amount of money in the bank, then dividing by the number of rounds before withdrawing.

Example math: 2-3-0 bank after depositing 4750. withdrawing at the end of round 4.
9004-4750 = 4254,
4254 / 4 rounds = 1,063.5, rounded to ~1,064 per round

Income earning per round (pre-11.0)[]

The following is information regarding income earning per round for the IMF Loan before it received a buff when combined with Benjamin. On Version 7.0 and later, there was a Monkey Bank nerf that did not affect IMF Loans or Monkey-Nomics.

Mathematics[]

Python code is written below as a demonstration of a rough model of a Monkey Bank simulation. Currently, this code does not take into account the presence of Benjamin's Bank buffs (multiply the total deposit per round by 1.05 or 1.12 for Level 5-8 and Level 9+, respectively).

Variables:

  • account: The bank balance of the current bank account. Code below declares it as $0 (0).
  • deposit: The total deposit per round into the current bank account. Code below declares it as $230 (230).
  • interestrate: The interest rate of the current bank account. Code below declares it as +15% per round (1.15).
  • capacity: The maximum bank capacity of the current bank account. Code below declares it as $10,000 (10000).
  • i: The iterator that loops the number of "rounds" for the Bank to run. Please change the hardcoded maximum i value to whatever number of rounds you wish.
Python Code for Monkey Bank mathematics
class Bank:
    def __init__(self, account, capacity):
        self.account = account
        self.capacity = capacity
    
    def bankrun(self, deposit, interestrate):
        self.account += deposit
        if (self.account >= self.capacity):
            print("bank is full")
        else:
            print("Bank balance after deposits: %s" % self.account)
        self.account *= interestrate
        if (self.account >= self.capacity):
            print("bank is full")
        else:
            print("Bank balance after interest: %s" % self.account)
        return self.account
        
bank = Bank(0, 10000)
print(bank.account)
print(bank.capacity)

deposit = 230
interestrate = 1.15
print("Deposit: %s" % deposit)
print("Interest rate: %s" % interestrate)
for i in range(0, 15):
    print("Iteration %s" % (i + 1))
    bank.bankrun(deposit, interestrate)

Additional Tips[]

  • The best crosspath choice for the basic Bank functionality is usually 2-4-0 for the maximum income gain, but for IMF Loan the 0-4-2 may be better if trying to utilize the higher sellback and reducing inconvenience of BankDepositsIcon Bank Deposits micro.
  • IMF Loan's ability takes a long time to go from initial cooldown. In the 30's rounds, it may take up to about 3 rounds in order for the ability to become ready without getting penalties in Ranked Boss.
  • Try to use strategies for Bank Deposits to maximize usage of manual deposits (see Bank Deposits#Strategy for further context).

Version History[]

Balance Changes[]

IMF Loan was formerly one of the least effective income-production towers in the game, not only because the loan's income gain was less than the cost of the upgrade itself, but because it initially did not have any other perks. Subsequently, it has evolved to become a stronger version of the Monkey Bank, more specifically because it kept the Monkey Bank's old bank capacity since Version 7.0, and its upgrade price was slashed to an acceptable level on an even earlier update. It also kept the benefit of Bank Deposits, later becoming popularized in Boss Events because of the income potential of that MK Point.

IMF Loan would become more popular among Ranked Boss players after Version 32.0 nerfed the Monkeyopolis to no longer be worth going for early, and is a dominant staple of Ranked Boss events that would be significantly curbed with nerfs to the IMF Loan Ability in Version 35.0. After v35.0, the IMF Loan is only used when farming with it can afford important towers which are unaffordable otherwise, such as a Ray of Doom or Plasma Monkey Fan Club, or during low ability cooldown weeks. Version 40.0 slightly buffed its value to compete against the revitalized one-Farm Monkeyopolis.

4.0
  • BUFF Cost of IMF Loan is cheaper ($12,000 → $7,500).
7.0
  • Change Indirect buff, because IMF Loan's capacity was kept at $10,000 but Monkey Bank's capacity was lowered to $7,000.
8.0
  • NERF IMF Loan ability (along with other income-based abilities) now undergo the full initial cooldown before initial ability usage.
12.0
  • NERF IMF Loan bonus cash produced per round reduced from $160 to $150 (from $240 per round to $230).
14.0
  • NERF Bug: If the IMF Loan's debt has been paid off, the Banana Farm that triggered it cannot use its ability until the next round starts. The same applies to Monkey-Nomics.
14.2
  • BUFF Bug fix; the ability no longer requires the next round to start upon paying off the IMF Loan (again, also applies to Monkey-Nomics).
18.0
  • BUFF Added Monkey Knowledge Point "Bank Deposits": this MK allows the player to deposit money into the Monkey Bank, earning interest over time.
19.0
  • NERF Deposits do not gain income until 1 round after being deposited.
  • BUFF [undocumented] Monkey Bank with EZ Collect (or Banana Salvage) will now glow upon detecting full once it adds another pocket of cash, rather than only just after the round it becomes full.
27.0
Given the relatively low value and use case of upgrading Banks further to IMF Loan, the overall incredible power of the Bank Deposits MK on Banks, and the fact that Banks are majorly considered to be the most powerful farm; we have decided to limit this incredibly powerful Knowledge point [sic] until the IMF Loan to both reign it in and give a little more back to that lacking T4 upgrade.
~ Ninja Kiwi
28.0
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. [...]
~ Ninja Kiwi, referring to Banana Salvage
  • BUFF 0-4-2 crosspath affected by various 0-3-2 Bank buffs
32.2
  • BUFF [bug fix] Resolved an issue where selling an IMF Loan at the same time and taking a loan would not immediately try to pay back the loan with that tower’s sellback
35.0
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, however along with this buff the current power of IMF loan on this path already feels too strong so we are lowering that power for IMF Loan in exchange.
~ Ninja Kiwi
  • BUFF IMF Loan will now increase in cash generation with external buffs.
    • [Undocumented] This does not affect the cash granted from abilities of IMF Loan or Monkey-Nomics.
  • NERF IMF Loan ability loaning quantity decreased from $10,000 → $9,000
  • NERF BackroomDealsIcon Backroom Deals bonus cash reduced from +$2,000 → +$1,000
    • Total reduction with BackroomDealsIcon decreased from $12,000 → $10,000
  • NERF Resolved a bug that caused Collecting All from multiple x3x Banks or higher to only target repayment back towards a single active IMF Loan
    • This is a nerf because it means that Collecting All cannot have multiple banks bypass Debt after 35.0, as before 35.0, they did not all need to pay debt when the debt of one is payed off.
    • This also applies to selling an IMF loan with bank deposits.
  • Change Upgrade name "IMF loan" has been corrected to "IMF Loan"
40.0
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.
~ Ninja Kiwi
  • BUFF IMF Loan cost reduced ($7500 → $7200)
    • Overall price decrease is $450, due to Monkey Bank costing $150 less.

Trivia[]

  • According to internal text, IMF stands for "International Monkey Fund". In real life, IMF is an abbreviation for International Monetary Fund, a financial agency that loans money to countries with troubled economies.
  • While the IMF Loan's loan mimicks many attributes of a loan, more specifically an automatic payment of an interest-free loan, it doesn't work the same as a loan from a real-world bank for the following reasons:
    • IMF Loan's loan never has income penalties for not paying back debt promptly. In addition, real-life loans typically have a maximum loan debt allowance, which otherwise would lead to financial consequences such as bankruptcy.
    • One can basically not pay back an IMF Loan for however amount of rounds as the player wishes without losing from forced bankruptcy.
    • Assuming the IMF Loans are run by the same company, paying off a loan with an existing loan from the same company would be not practical, since that would be counterintuitive to a bank.
  • There was a known bug related to IMF Loan in Co-Op where towers can disappear when the server refreshes the map to sync the game if there is an IMF Loan present on the map. This seems to be patched around version 12.0.
