Calculate Compound Interest and Future Value of Principal 1.05 (Dollar, Euro, Pound). Duration: 5 Years, 6 Months and 11 Days. Annual Interest Rate: 2.00%. Compounded Daily

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 = 1.05
  • r, Annual compound interest rate, r = 2.00%

  • n, Number of times the interest compounds during a year
    Compound frequency: daily (360 times a year)
    n = 360
  • r/n = 2.00%/360 = (2.00 ÷ 100)/360 = 2.00/(100 × 360)
    r/n = 0.000055555556

  • t, Duration of the investment
    n×t, Duration of the investment, related to n
  • n×t = 5 years × 360 days / year + 6 months × 30 days / month + 11 days

    n×t = 1,991 days

» Compound Interest: what is it, how is it calculated?


Calculate FV
Substitute for the values in the FV formula:

FV =


P × (1 + r/n)n×t =


1.05 × (1 + 0.000055555556)1,991 =


1.05 × 1.0000555555561,991 =


1.05 × 1.116957018099 ≈


1.17


[3] Compound Interest amount, CI
Calculation formula

  • Compound Interest amount is calculated as the difference between the Future Value of the investment and the Principal.

CI = FV - P

  • CI, Compound Interest amount
  • FV, Future investment Value
  • P, Principal (initial amount)

CI ≈


1.17 - 1.05 ≈


0.12

Calculator: Compound Interest, Future Investment Value

FV = P × (1 + r/n)n×t + A × [(1 + r/m)m×t - 1] ÷ r/m

FV = Future Value of investment

P = Principal amount invested (the original contribution)

A = Regular contribution (additional money added periodically to the initial investment, P)

r = Annual Interest Rate the investment is earning

n = Number of times the interest compounds during a year

m = Number of times the regular contribution is made during a year

t = Number of years the investment is going to be active

t and r are expressed using the same time units
