Detailed calculations of the simple (flat) interest rate
Notations and variables used:
Principal (initial amount), P = 95,782.8
Amount produced by the interest, I = 518
From date: Jan 24, 862
To date: Jul 24, 2018
Duration, T = 422,401 days (13,878 Months)
Transaction fee rate, F% = 0.02%
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 × 518) ÷ (95,782.8 × 422,401))% =
(18,907,000 ÷ 40,458,750,502.8)% ≈
0.00046731547% ≈
0%
Calculate E, the amount earned after adding to the principal the amount produced by the simple (flat rate) interest
E = P + I =
95,782.8 + 518 =
96,300.8
Calculate L, the amount left after deducting the transaction fee
F = F% × E ⇒
L = E - F =
E - F% × E =
(1 - F%) × E =
(1 - 0.02%) × 96,300.8 =
99.98% × 96,300.8 =
96,281.53984 ≈
96,281.54
Calculate Pr, the profit of the investment
Pr = L - P =
96,281.53984 - 95,782.8 =
498.73984 ≈
498.74
Used symbols: % percent, ÷ divide, × multiply, = equal, ≈ approximately equal.
