Detailed simple (flat rate) interest calculations
Notations and variables used:
Simple (flat rate) interest amount, I
Principal (initial amount), P = - 1,882
Annual simple interest rate, R = 356%
From date: Jan 21, 1998
To date: Apr 21, 2020
Duration, T = 8,126 days (267 Months)
Transaction fee rate, F% = 166%
Transaction fee amount, F
Number of days in a year, N = 365
Calculate the amount of the simple (flat rate) interest, I
The simple (flat rate) interest calculation formula:
I = (P × R × T) ÷ N ⇒
I = (P × R × T) ÷ N =
(- 1,882 × 356% × 8,126) ÷ 365 =
(- 1,882 × 356 × 8,126) ÷ (365 × 100) =
- 5,444,354,992 ÷ 36,500 ≈
- 149,160.410739726027 ≈
- 149,160.41
Calculate the amount earned after adding the simple (flat rate) interest to the principal, E
E = P + I =
- 1,882 + (- 149,160.410739726027) =
- 1,882 - 149,160.410739726027 =
- 151,042.410739726027 ≈
- 151,042.41
Calculate the amount left after deducting the transaction fee, L
F = F% × E ⇒
L = E - F =
E - F% × E =
(1 - F%) × E =
(1 - 166%) × - 151,042.410739726027 =
- 66% × - 151,042.410739726027 ≈
99,687.991088219178 ≈
99,687.99
Calculate the profit of the investment, Pr
Pr = L - P =
99,687.991088219178 - (- 1,882) =
99,687.991088219178 + 1,882 =
101,569.991088219178 ≈
101,569.99
