Here is an example of how interest is compounded semi-annually-

A person invests Rs. 6,000 in an investment for five years. He is going to receive 3% semi-annual compound interest.

  • First, change the interest rate to decimal- 3/100= 0.03
  • Determine the number of compounding terms

In this case, interest will be calculated over five years. Every year will have two compounding periods, except for the first year. The first year will have one compounding period. Therefore, in total, there are 9 compounding periods.

  • Use the formula

6,000[(1+.03)^9-1]= Rs. 1,830.

The total interest accrued over the five years will be Rs. 1,830.
