| Unless I am mistaken, it works the same as other types of accounts.
Example : you have $1000 in an account at 4.16%/m ( ! ): at the end of the month, you will have earned $41.6 as interests, thus your balance would be $1041.6.
But you make interest with interests : next month, you would also earn interest on those 41.6, not just on 1000.
4,16% per month seems high though ! ( what 's the name of your bank !? )
Now, if it's per year ( much more likely ):
1000 x 0.0416 / 12 = $3.47 interests on the 1st month.
second month : ( 1000 + 3.47 ) x 0.0416 /12
and so on... |
