Detailed calculations of the simple (flat) interest rate
Notations and variables used:
Principal (initial amount), P = 111,362
Amount produced by the interest, I = 135
From date: Dec 31, 718
To date: Aug 31, 2018
Duration, T = 474,694 days (15,596 Months)
Transaction fee rate, F% = 990%
Transaction fee amount, F
Number of days in a year, N = 365
Calculate R, the annual simple (flat) interest rate to earn the amount I
The simple (flat rate) interest calculation formula:
I = (P × R × T) ÷ N ⇒
R = (N × I) ÷ (P × T) =
100% × (N × I) ÷ (P × T) =
((100 × N × I) ÷ (P × T))% =
((100 × 365 × 135) ÷ (111,362 × 474,694))% =
(4,927,500 ÷ 52,862,873,228)% ≈
0.000093212868% ≈
0%
Calculate E, the amount earned after adding to the principal the amount produced by the simple (flat rate) interest
E = P + I =
111,362 + 135 =
111,497
Calculate L, the amount left after deducting the transaction fee
F = F% × E ⇒
L = E - F =
E - F% × E =
(1 - F%) × E =
(1 - 990%) × 111,497 =
- 890% × 111,497 =
- 992,323.3
Calculate Pr, the profit of the investment
Pr = L - P =
- 992,323.3 - 111,362 =
- 1,103,685.3
Used symbols: % percent, ÷ divide, × multiply, = equal, ≈ approximately equal.
