Detailed simple (flat rate) interest calculations
Notations and variables used:
Simple (flat rate) interest amount, I
Principal (initial amount), P = 1
Annual simple interest rate, R = 314%
From date: Jan 1, 1
To date: Dec 1, 9999
Duration, T = 2,921,543 days (119,987 Months)
Transaction fee rate, F% = 162%
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 × 314% × 2,921,543) ÷ 365 =
(1 × 314 × 2,921,543) ÷ (365 × 100) =
917,364,502 ÷ 36,500 ≈
25,133.27402739726 ≈
25,133.27
Calculate the amount earned after adding the simple (flat rate) interest to the principal, E
E = P + I =
1 + 25,133.27402739726 =
25,134.27402739726 ≈
25,134.27
Calculate the amount left after deducting the transaction fee, L
F = F% × E ⇒
L = E - F =
E - F% × E =
(1 - F%) × E =
(1 - 162%) × 25,134.27402739726 =
- 62% × 25,134.27402739726 ≈
- 15,583.249896986301 ≈
- 15,583.25
Calculate the profit of the investment, Pr
Pr = L - P =
- 15,583.249896986301 - 1 =
- 15,584.249896986301 ≈
- 15,584.25
Used symbols: % percent, ÷ divide, × multiply, = equal, ≈ approximately equal.
