Detailed simple (flat rate) interest calculations
Notations and variables used:
Simple (flat rate) interest amount, I
Principal (initial amount), P = 19,570
Annual simple interest rate, R = 3%
From date: Jul 8, 2017
To date: Aug 1, 2017
Duration, T = 24 days
Transaction fee rate, F% = 200%
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 =
(19,570 × 3% × 24) ÷ 365 =
(19,570 × 3 × 24) ÷ (365 × 100) =
1,409,040 ÷ 36,500 ≈
38.603835616438 ≈
38.6
Calculate the amount earned after adding the simple (flat rate) interest to the principal, E
E = P + I =
19,570 + 38.603835616438 =
19,608.603835616438 ≈
19,608.6
Calculate the amount left after deducting the transaction fee, L
F = F% × E ⇒
L = E - F =
E - F% × E =
(1 - F%) × E =
(1 - 200%) × 19,608.603835616438 =
- 100% × 19,608.603835616438 =
- 19,608.603835616438 ≈
- 19,608.6
Calculate the profit of the investment, Pr
Pr = L - P =
- 19,608.603835616438 - 19,570 =
- 39,178.603835616438 ≈
- 39,178.6
