Compound interest is the process of adding interest to the preliminary number of an investment, and from then on earning further interest on this new amount. This is positive from easy interest, in which the rate is applied once to the preliminary number and then multiplied by the term of the investment.
The vast majority of investment vehicles offer composition interest.

Calculating composition interest is not as right forward as easy interest, although it is not particularly difficult once the underlying method is known. The remainder of this record outlines the method to use.
In order to make the calculation it is primary to know both the periodic rate of interest and the compounding period. Given these two facts it is possible to decide the return on investment over a given period, as well as a nominal yearly rate and yearly division rate (Apr), two means of comparing investments contribution separate compounding periods.
Compounding periods will generally be one of daily, monthly, quarterly or yearly, although technically any fixed duration is possible.
For instance a compounding duration of monthly and periodic rate of 1% means every month interest is calculated at 1% and added to the primary (initial amount). This is the same as an list that has a monthly compounding duration with a 12% nominal yearly interest rate (12% / 12 months = 1%).
Definition of terms:
Pv = gift value of a sum (initial investment, or principal)
Fv = hereafter value of a sum (the total equilibrium at the end of a given period)
i = the periodic rate of interest
n = the number of compounding periods in a sum
The method to calculate the hereafter value of an preliminary investment is then:
Fv = Pv(1 + i)^n
In the method ^ means to the power of. For instance 2^3 is 2 to the power of 3, which is 8.
For example what is the hereafter value of investing ,000 for 10 years at a nominal yearly rate of 12% given a compounding duration of monthly?
Pv, the gift value is ,000
i, the periodic interest rate is 12% / 12 months = 0.12 / 12 = 0.01
n, the number of compounding periods, is 10 years 12 months = 120 months
So plugging in the numbers:
Fv = 1000 (1 + 0.01)^120 = ,300.39
In other words, the investment returns ,300.39 in interest over the ten years.
Although it is right forward to calculate composition interest this way it is also possible to use an online calculator.
