The rate of return monthly, as Kenneth said,
is 14%/12 = 1.167 % per month.
On the first month you would earn $175 interest
However, on each subsequent month the interest
earned for the month is a little higher than the
previous due to the rise in the amount of money
in the investment account.
For the year:
A = 15,000(1+.14/12)12 = $17,240.13
This means the interest for the year was
$2,240.13
As a monthly average we earned:
2240.13/12 = $186.68 average interest earned per month
