Calculation formula. Used notations. Project Breakdown.
[1] Calculation method used: 30 / 360
Number of days in a month = 30
Number of days in a year = 360
[2] Future Investment Value, FV
Calculation formula:
FV =
P × (1 + r/n)n×t
FV, Future Investment Value
P, Principal (initial amount), P = 700.00
r, Annual compound interest rate, r = 0.02%
n, Number of times the interest compounds during a year
Compound frequency: daily (360 times a year)
n = 360
r/n = 0.02%/360 = (0.02 ÷ 100)/360 = 0.02/(100 × 360)
r/n = 0.000000555556
t, Duration of the investment
n×t, Duration of the investment, related to n
n×t =
+ 1 month × 30 days / month
n×t = 30 days
Calculate FV
Substitute for the values in the FV formula:
FV =
P × (1 + r/n)n×t =
700.00 × (1 + 0.000000555556)30 =
700.00 × 1.00000055555630 =
700.00 × 1.000016666814 ≈
700.01
[3] Compound interest amount, CI
Calculation formula
CI = FV - P
CI, compound interest amount
FV, Future Investment Value
P, Principal (initial amount)
CI ≈
700.01 - 700.00 ≈
0.01
