First, your aim is to maximize the highest effective rate. That means you double the 5% birthday/partner promo jars to 10%. I computed the figure to be 36.60 MYR.
Then, you move to the next highest effective rate, i.e., the normal saving jars, you seek to double the rates from 3.6 to 7.2%, I computed the figure to be 50.84 MYR per pocket for a total of 8 pockets maximum = total 406.72 MYR.
Lastly you double the DSA rate from 2.5% to 5% = magic number is 73.20 MYR.
--------------------------------------
After this, you dump all your remaining money back into the 5% birthday jar and promo jars up to the maximum limit possible. Remember, for the special jars, anything above 36.60 MYR will earn 5% p.a. (the marginal interest rate).
After you hit the limit for all
special jars, dump 1006.50 MYR into GX Bank to earn the 4% effective rate.
If there's anything leftover, you then dump the rest into the normal saving jars (for effective rate of 3.6% p.a.)
If all 8 saving jars at BoostBank are full, you go down the "effective rate chain" further and move money to Rize (3.3%).
Further down you have TnG Go+ of around 3.4% p.a., and further down you have AEON Bank 3% -> BoostBank DSA 2.5% p.a. (anything above 73.20 MYR earns marginal rate of 2.5% p.a.) -> GX Bank 2% p.a. (anything above 1006.50 at GX Bank earns marginal rate of 2% p.a.).
Thank you.
I going to try yr magic number on GxBank, since it's empty now.
