Principal (initial amount), P = 40,000
Annual simple interest rate, R = 2%
From date: Jun 5, 2018
To date: Jul 5, 2019
Duration, T = 395 days (13 Months)
Commission fee (withdrawal or payment), F = 0%
No. of days in a year, N = 365
I = Simple interest:
I = (P × R × T) ÷ N =
(40,000 × 2% × 395) ÷ 365 =
(40,000 × 2 × 395) ÷ (365 × 100) =
31,600,000 ÷ 36,500 ≈
865.753424657534 ≈
865.75
B = Amount earned:
B = P + I =
40,000 + 865.753424657534 =
40,865.753424657534 ≈
40,865.75
