Compound interest refers to the process in which the interest associated with a savings account, loan, or investment rises over time exponentially instead of linearly. It is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods. The rate at which compound interest accrues depends on the frequency of compounding, such that the higher the number of compounding periods, the greater the compound interest.

This is what differentiates it from simple interest. If the interest differs every year and gets increased if we stop paying every month then we can say the loan is charged with compound interest. It is used to calculate changes in population and computing growth of bacteria etc.,

A = amount

P = principal

t = time period

Compound interest is an interest charged on a certain sum of money. It can be calculated annually, quarterly and half - yearly. Compound interest is charged on the principal amount and the interest. This is the difference between simple and compound interest. Simple interest is calculated just on the principal amount. Generally banks offer loans for compound interest. If you look at the bank statement and find the interest rate changing every year and increasing then you can understand that you are being charged with compound interest.
