Compound Interest Definition

Compound interest is the interest calculated on the principal and the interest accumulated over the previous period. It is different from the simple interest where interest is not added to the principal while calculating the interest during the next period. Compound interest finds its usage in most of the transactions in the banking and finance sectors and also in other areas as well. Some of its applications are:

  1. Increase or decrease in population.
  2. The growth of bacteria.
  3. Rise or depreciation in the value of an item.

Compound Interest Formula

The compound interest formula is given below:

Compound Interest =  Final Amount –original Principal

Let us get to know the values of Amount and Interest in case of Compound Interest for different years-

Time (in years) Amount Interest
1 P(1 + R/100) (R/100) PR100
2 P(1+R100)2 P(1 + R/100) (R/100)
3 P(1+R100)3 P(1 + R/100)2 (R/100)
4 P(1+R100)4 P(1 + R/100)3 (R/100)
n P(1+R100)n P(1 + R/100)n-1 (R/100
