Principal (initial amount), P = 12,000,000


Annual simple interest rate, R = 12%


From date: Mar 13, 2018


To date: Mar 13, 2019


Duration, T = 365 days (12 Months)


Commission fee (withdrawal or payment), F = 80%


No. of days in a year, N = 365


I = Simple interest:

I = (P × R × T) ÷ N =


(12,000,000 × 12% × 365) ÷ 365 =


(12,000,000 × 12 × 365) ÷ (365 × 100) =


52,560,000,000 ÷ 36,500 =


1,440,000

B = Amount earned before deducting the
commission fee (withdrawal or payment):

B = P + I =


12,000,000 + 1,440,000 =


13,440,000

D = Amount earned after deducting the
commission fee (withdrawal or payment):

D = B - F =


B - F% × B =


(1 - F%) × B =


(1 - 80%) × 13,440,000 =


20% × 13,440,000 =


2,688,000

Pr = Investment profit:

Pr = D - P =


2,688,000 - 12,000,000 =


- 9,312,000
