Detailed simple (flat rate) interest calculations
Notations and variables used:
Simple (flat rate) interest amount, I
Principal (initial amount), P = - 1,650
Annual simple interest rate, R = 492%
From date: Apr 21, 1998
To date: Apr 21, 2020
Duration, T = 8,036 days (264 Months)
Transaction fee rate, F% = 424%
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 =
(- 1,650 × 492% × 8,036) ÷ 365 =
(- 1,650 × 492 × 8,036) ÷ (365 × 100) =
- 6,523,624,800 ÷ 36,500 ≈
- 178,729.446575342466 ≈
- 178,729.45
Calculate the amount earned after adding the simple (flat rate) interest to the principal, E
E = P + I =
- 1,650 + (- 178,729.446575342466) =
- 1,650 - 178,729.446575342466 =
- 180,379.446575342466 ≈
- 180,379.45
Calculate the amount left after deducting the transaction fee, L
F = F% × E ⇒
L = E - F =
E - F% × E =
(1 - F%) × E =
(1 - 424%) × - 180,379.446575342466 =
- 324% × - 180,379.446575342466 ≈
584,429.40690410959 ≈
584,429.41
Calculate the profit of the investment, Pr
Pr = L - P =
584,429.40690410959 - (- 1,650) =
584,429.40690410959 + 1,650 =
586,079.40690410959 ≈
586,079.41
