I got my first round of bonus interest from UOB One. I checked the bonus interest history details and the MAB for May-2024 was $153,534.42 and bonus interest (level 2) earned was $503.21.
Is the amount of bonus interest earned correct?
Perhaps you have seen some base interest credited on 31 May eg. $6.37 (0.05%)
Total interest is base interest ($6.37) + bonus interest ($503.21) = $509.58
Calculation of total interest, based on MAB (mthly avg balance) = (First $75k@ 3%=$191.09) + (Next $50k@ 4.5%=$191.09) + (Next $25k@ 6%=$127.40) = $509.58
For UOB One a/c bonus interest, in the absence of any additional promo which has other criteria to fulfill, it is better to manage the MAB equal or very close to $150k. I notice that anything more than $150k does not seems to earn base interest or perhaps I keep at very close to $150k.
