#### What is Simple Interest?

Simple Interest (S.I) is the method of calculating the interest amount for some principal amount of money.

#### Simple Interest Formula

The Formula for simple interest helps you to find the interest amount if the principal amount, rate of interest and time periods are given.

Simple interest formula is given as

**SI = (P × R ×T) / 100**

Where

SI = simple interest

P = principal

R = interest rate (in percentage)

T = time duration (in years)

In order the calculate the total amount, the following formula is used:

**Amount (A) = Principal (P) + Interest (I)**

Where,

**Amount **(A) is the total money paid back at the end of the time period for which it was borrowed.

#### Difference Between Simple Interest and Compound Interest

There is another type of interest called compound interest. The major difference between simple and compound interest is that simple interest is based on the principal amount of a deposit or a loan whereas the compound interest is based on the principal amount and interest that accumulates in every period of time
