A = P ( 1 + r / n)nt
Amount of savings = Principal originally invested * (1 + decimal annualized rate of interest / number of compounding periods per year)times per year interest is compounded * years invested
Then to figure out the interest earnings you would subtract the original principal from the result.
A = P ( 1 + r / n)nt - P
$1,105.08 = $1,000 ( 1 + 0.0016666667/12) 12 * 5
$1,105.08 - $1,000 = $105.08
