Simple (Flat Rate) Interest Calculator: Calculate the Annual Simple (Flat) Interest Rate of the Invested Amount of Money (Principal, Initial Starting Amount Lent, Deposited or Borrowed), of 927 units (Dollar, Euro, Pound, etc.) To Produce a Sum of Money of 1,000,000,000,000 units, for a period of 530,483 days (17,429 Months). The transaction fee is 332%
Detailed calculations of the simple (flat) interest rate
Notations and variables used:
Principal (initial amount), P = 927
Amount produced by the interest, I = 1,000,000,000,000
From date: Oct 30, 564
To date: Mar 30, 2017
Duration, T = 530,483 days (17,429 Months)
Transaction fee rate, F% = 332%
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 × 1,000,000,000,000) ÷ (927 × 530,483))% =
(36,500,000,000,000,000 ÷ 491,757,741)% ≈
74,223,539.269105272712% ≈
74,223,539.27%
Calculate E, the amount earned after adding to the principal the amount produced by the simple (flat rate) interest
E = P + I =
927 + 1,000,000,000,000 =
1,000,000,000,927
Calculate L, the amount left after deducting the transaction fee
F = F% × E ⇒
L = E - F =
E - F% × E =
(1 - F%) × E =
(1 - 332%) × 1,000,000,000,927 =
- 232% × 1,000,000,000,927 =
- 2,320,000,002,150.64
Calculate Pr, the profit of the investment
Pr = L - P =
- 2,320,000,002,150.64 - 927 =
- 2,320,000,003,077.64
Used symbols: % percent, ÷ divide, × multiply, = equal, ≈ approximately equal.
