Principal (initial amount), P = 45,000
Annual simple interest rate, R = 7.9%
From date: Feb 14, 2018
To date: Mar 14, 2018
Duration, T = 28 days
Commission fee (withdrawal or payment), F = 0%
No. of days in a year, N = 365
I = Simple interest:
I = (P × R × T) ÷ N =
(45,000 × 7.9% × 28) ÷ 365 =
(45,000 × 7.9 × 28) ÷ (365 × 100) =
9,954,000 ÷ 36,500 ≈
272.712328767123 ≈
272.71
B = Amount earned:
B = P + I =
45,000 + 272.712328767123 =
45,272.712328767123 ≈
45,272.71
