Calculation method used. Calculation formula. Used notations
[1] Calculation method used: 30 / 360
Number of days in a month = 30
Number of days in a year = 360
[2] Simple interest, I
Calculation formula:
I =
(P × r × t) ÷ 360
I = Simple interest amount
360 = Number of days in a year
P = Principal (initial amount)
P = 2,384.00 units (Dollar, Euro, Pound, etc.)
r = Annual simple interest rate, r = 2.20%
t = Duration of the investment, in days
t = 1 year, 1 month and 14 days
t =
+ 1 year × 360 days / year
+ 1 month × 30 days / month
+ 14 days
t = 404 days
Calculate the simple interest amount
[3] Substitute for the values
in the Simple Interest formula:
I =
(P × r × t) ÷ 360 =
(2,384.00 × 2.20% × 404) ÷ 360 =
2,384.00 × 2.20 ÷ 100 × 404 ÷ 360 =
(2,384.00 × 2.20 × 404) ÷ (360 × 100) =
2,118,899.2 ÷ 36,000 ≈
58.858311111111 ≈
58.86
[4] V = Amount earned before deducting the
Withdrawal Fee Amount:
V = P + I =
2,384.00 + 58.86 =
2,442.86
Withdrawal Fee Amount, Fw. Financial gain, Pr
[6] The amount charged for withdrawing the money
Fw = Fw% × V
Fw, Withdrawal Fee Amount
Fw%, Commission Fee % (on withdrawal), as a percentage
V, Amount earned, V = P + I
Fw =
Fw% × V =
1% × 2,442.86 =
1/100 × 2,442.86 =
(1 × 2,442.86)/100 =
2,442.86/100 =
2,442.86 ÷ 100 =
24.4286 ≈
24.43
[7] Financial gain, Pr:
Pr = I - Fw
Pr, financial gain
I, simple interest amount
Fw, Withdrawal Fee Amount
Pr =
I - Fw =
58.86 - 24.43 =
34.43
Answer:
Principal (initial amount) = 2,384.00
Amount earned = 2,442.86
Simple interest amount = 58.86
Withdrawal Fee Amount = 24.43
Financial gain = 34.43
