HELLO FRND
________

Interest is of two types, simple interest and compound interest

Simple Interest: When the interest is calculated on the principal amount, then that interest is called simple interest.

Compound interest: After the fixed period, the interest earned to get a new principal has been added to the previous principal. For the next fixed period of time, if interest is calculated on the new principal, then that interest is called compound interest.

Compound interest phase: In each stage, the period of time after which compound interest is the reason, is called the phase of compound interest. Generally, stages of compound interest are calculated for 3 months, 6 months and 1 year.

Amount under compound interest: The amount of principal and compound interest for a specific period is known as the amount.
