Detailed calculations of the simple (flat) interest rate
Notations and variables used:
Principal (initial amount), P = 16,410
Amount produced by the interest, I = 380
From date: Aug 25, 442
To date: Jul 25, 2016
Duration, T = 574,861 days (18,887 Months)
Transaction fee rate, F% = 516%
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 × 380) ÷ (16,410 × 574,861))% =
(13,870,000 ÷ 9,433,469,010)% ≈
0.001470296874% ≈
0%
Calculate E, the amount earned after adding to the principal the amount produced by the simple (flat rate) interest
E = P + I =
16,410 + 380 =
16,790
Calculate L, the amount left after deducting the transaction fee
F = F% × E ⇒
L = E - F =
E - F% × E =
(1 - F%) × E =
(1 - 516%) × 16,790 =
- 416% × 16,790 =
- 69,846.4
Calculate Pr, the profit of the investment
Pr = L - P =
- 69,846.4 - 16,410 =
- 86,256.4
Used symbols: % percent, ÷ divide, × multiply, = equal, ≈ approximately equal.
