Future Value of an Ordinary Annuity | |||
= C*[(1+i)^n-1]/i | |||
Where, | |||
C= Cash Flow per period | |||
i = interest rate per period | |||
n=number of period | |||
800000= C[ (1+0.004166667)^300 -1] /0.004166667 | |||
800000= C[ (1.004166667)^300 -1] /0.004166667 | |||
800000= C[ (3.4813 -1] /0.004166667] | |||
=$1343.39 | |||
Total payment = $1343.3869*12*25 | |||
403016.07 | |||
=$403016.07 | |||
Interest earned = $800000-403016.08 | |||
=$396983.92 | |||
