sorry korkor me maths noob, assuming every month i withdraw the interest, is $9777 still better than $10000? thanks in advance~
As 2.5% interest rate is only applicable up to 10,000 SGD. Interest earned on this amount (credited at the end of first month); earns 1% only for the remaining 11 months. Hence; the total interest for 9777 and 10000 might be same if you leave it for 1 year.
But if you withdraw you interest monthly; then the account balance at every month-end (policy monthiversary) remains 10000 SGD; hence, whole amount earns interest at 2.5 %.
I have done some rough maths:
Principal up to Annual Interest Daily equivalent
10000
2.5 6.7607E-05
from 10000 to 100,000
1 2.72429E-05
Principal Amount 10000
