Compound Interest [Using Formula]
Compound Interest when compounded semi-annually:
 What is the compound interest on rupees “P” at “r%” semi-annually for 3

years?
a. The time period is divided equally into time periods of 1
2
year each.
b. The rest of the procedure remains the same.
c. {Interest at the end of (n + 1)th period =
𝑃𝑛×𝑟×

Compound Interest with different rates in successive years:
a. Interest at the end of each time period will be calculated using the rates specific to that
time period.
b. The rest of the procedure remains the same.
General Formulae: Computing Amount and Compound Interest:

annually) at the end of N years 𝐴 = 𝑃(1 +
