Principal (initial amount), P = 1,000
Annual simple interest rate, R = 0.5%
From date: May 6, 2017
To date: May 6, 2037
Duration, T = 7,305 days (240 Months)
Commission fee (withdrawal or payment), F = 806%
No. of days in a year, N = 365
I = Simple interest:
I = (P × R × T) ÷ N =
(1,000 × 0.5% × 7,305) ÷ 365 =
(1,000 × 0.5 × 7,305) ÷ (365 × 100) =
3,652,500 ÷ 36,500 ≈
100.068493150685 ≈
100.07
B = Amount earned before deducting the
commission fee (withdrawal or payment):
B = P + I =
1,000 + 100.068493150685 =
1,100.068493150685 ≈
1,100.07
D = Amount earned after deducting the
commission fee (withdrawal or payment):
D = B - F =
B - F% × B =
(1 - F%) × B =
(1 - 806%) × 1,100.068493150685 =
- 706% × 1,100.068493150685 ≈
- 7,766.483561643836 ≈
- 7,766.48
Pr = Investment profit:
Pr = D - P =
- 7,766.483561643836 - 1,000 =
- 8,766.483561643836 ≈
- 8,766.48
