Detailed simple (flat rate) interest calculations
Notations and variables used:
Simple (flat rate) interest amount, I
Principal (initial amount), P = 118
Annual simple interest rate, R = 986%
From date: Mar 11, 966
To date: Feb 11, 2018
Duration, T = 384,207 days (12,623 Months)
Transaction fee rate, F% = 504%
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 =
(118 × 986% × 384,207) ÷ 365 =
(118 × 986 × 384,207) ÷ (365 × 100) =
44,701,716,036 ÷ 36,500 ≈
1,224,704.548931506849 ≈
1,224,704.55
Calculate the amount earned after adding the simple (flat rate) interest to the principal, E
E = P + I =
118 + 1,224,704.548931506849 =
1,224,822.548931506849 ≈
1,224,822.55
Calculate the amount left after deducting the transaction fee, L
F = F% × E ⇒
L = E - F =
E - F% × E =
(1 - F%) × E =
(1 - 504%) × 1,224,822.548931506849 =
- 404% × 1,224,822.548931506849 ≈
- 4,948,283.09768328767 ≈
- 4,948,283.1
Calculate the profit of the investment, Pr
Pr = L - P =
- 4,948,283.09768328767 - 118 =
- 4,948,401.09768328767 ≈
- 4,948,401.1
