Calculate Simple Interest







Formula

The formula to calculate simple interest is:

\[ SI_{\text{Annual}} = \frac{P_{\text{Annual}} \cdot r_{\text{Annual}} \cdot t_{\text{Annual}}}{100} \]

Where:

Definition

Simple Interest is the extra amount gained or paid on the principal amount for the time period at a fixed rate of interest.

Principal Amount of Simple Interest is the amount invested, borrowed, or lent initially at a fixed rate for a given duration of time.

Annual Rate of Simple Interest is the percent of the simple interest paid over the principal amount for the due period.

Time Period of Simple Interest is the number of years for which the principal amount is invested, borrowed, or lent at a fixed rate of interest.

Example Calculation

Let's assume the following values:

Using the formula:

\[ SI_{\text{Annual}} = \frac{1000 \cdot 10 \cdot 2}{100} = 200 \]

The simple interest is 200.
