Just an added bonus for those of you who wanna maximize everything to the extreme, given now that we can open so many 5% jars.

We already know that the first 36.60 MYR will earn the effective 10% p.a. interest.

I said earlier that anything above 36.60 will earn 5% p.a., but that's not entirely correct.

The next (and subsequent) 0.01 MYR interest crediting (above the original 0.01 MYR on the 36.60 principal) will only occur when the interests are 0.015, 0.025, 0.035, 0.045 etc.

Let's do some checking:

1. (0.005/0.05)*366 = 36.60
2. (0.015/0.05)*366 = 109.80
3. (0.025/0.05)*366 = 183
4. (0.035/0.05)*366 = 256.20

and so on.

Notice the difference between the consecutive cases (4-3, 3-2, 2-1) are all by the exact same amount 73.20 MYR. It makes sense because the marginal interest rate is 5% p.a., and so 73.20 MYR * 0.05 / 366 = 0.01 MYR (this is where the extra 0.01 comes from on top of the original 36.60 MYR).

If your deposit amount is between the numbers (e.g. 109.80 > 5% jar amount > 36.60, 183 > 5% jar amount > 109.80, etc.), you will only earn up to the previous case's interest.

E.g. if you deposit 50 MYR, you earn case 1's interest of 0.01 MYR (this is as if you deposited only 36.60 MYR).

So if you want to fully utilize your money, make sure you arrange your deposits such that it hits exactly the number 36.60, 109.80, 183, 256.20 etc. Anything in between is deemed "inefficient".

You can obtain the "cases" by applying the formula (0.005+n*0.01)/0.05*366 where n = 0, 1, 2, 3, ... (For the mathematically-inclined, the number sequence forms an arithmetic progression with starting value, a = 36.60 and common difference, d = 73.20, T_n = a + (n-1)*d, n = 1,2,3,...)

support what JudgeCheezels said 10days days ago?

those guys were badmouthing Boost so much,
apps poor yes but
>>Also the 5% P.A is secretly limited, it’s already fully allotted since yesterday. You can go put in your 25k today on that special jar and you’ll get an error. They never mentioned any of this in their T&C.>>

totally not true.

CelcomDigi Jar interest in. All BoostBank interests credited successfully... time to sleep...

The 4 Sabah jars are over-subscribed. No more new deposits possible.

Guys the Sabah jars have been reopened!

Applied for BoostBank debit card 2 days ago. Card arrived today! RM 10 cashback. Now waiting for 2% cashback announcement... 

from TOS2 (he has exceeded the 3post time limit for now so i'm posting on his behalf)

Based on what has been checked so far, DSA stays at 2.5% p.a.: https://support.myboostbank.co/hc/en-gb/art...st-Bank-account

All 8 normal saving jars and Celebration jar rates are down to 3% p.a.:

(Normal saving jar) https://support.myboostbank.co/hc/en-gb/art...my-Savings-Jars

(Celebration jar) https://support.myboostbank.co/hc/en-gb/art...campaign-period

All special jars, including CelcomDigi and Sabah jars rate dropped to 3.3% p.a. Check the promos T&C here: https://support.myboostbank.co/hc/en-gb/cat...n-and-Campaigns

Don't trust the numbers on the app for now. They are outdated and keep fluctuating, especially the special jars... sometimes showing 3.3% p.a., sometimes showing 3.6% p.a.
----------------------------

Magic numbers:

2.5% DSA: Minimum 0.005*365/0.025 = 73, at increment of 0.01*365/0.025 = 146 for every extra cent of interest (no max limit *, 50k daily transfer limit cap)

3.0% normal saving jar + Celebration jar: Minimum 0.005*365/0.030 = 60.84, at increment of 0.01*365/0.03 = 121.67 for every extra cent of interest (Normal jar max limit is 1 million, but to earn interest, max needed is just 60.84 + 121.67 * 8218 = 999,944.90 per jar, uhmmm let's push it further, since we will get 999,944.90 * 0.03/365 = 82.19 per day at this juncture, might as well target 82.185 per day right? Hence, the maximum principal to put in is 82.185*365/0.03 = 999,917.50.

For celebration jar, repeat the same and you shall get max principal of 24,880.84, with max daily interest of 2.05)

3.3% special saving jar: Minimum 0.005*365/0.033 = 55.31, at increment of 0.01*365/0.033 = 110.61 for every extra cent of interest (I will leave it as an exercise for you to show that for the 50k CelcomDigi jar, if you are eligible, the max principal to put is 49938.64 and you get max daily interest of 4.52 MYR.)

* after credit transfer verification, max across all balance including saving jars: RM 100,000,000, see https://myboostbank.co/terms-and-conditions section C, item 3)

Kindly double check the calculations yea.
