The formula to calculate the time period of simple interest is:
\[ t_{\text{Annual}} = \frac{100 \cdot \text{SI}_{\text{Annual}}}{P_{\text{Annual}} \cdot r_{\text{Annual}}} \]
Where:
The 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.
Simple interest is the extra amount gained or paid on the principal amount for the time period at a fixed rate of interest.
The principal amount of simple interest is the amount invested, borrowed, or lent initially at a fixed rate for a given duration of time.
The annual rate of simple interest is the percent of the simple interest paid over the principal amount for the due period.
Let's assume the following values:
Using the formula:
\[ t_{\text{Annual}} = \frac{100 \cdot 200}{1000 \cdot 10} = 2 \]
The time period is 2 years.
