How is simple interest calculated?

Simple interest is calculated by taking the principal amount, multiplying it by the rate of interest, and then further multiplying it by the time that the money is invested or borrowed, expressed in years. This formula allows you to find out how much interest will be earned or paid over that time period.

The formula is represented as:

Simple Interest = Principal x Rate x Time

This method is straightforward, as it relies solely on these three variables. By understanding that principal refers to the initial sum of money, the rate is the percentage at which interest is calculated, and time is the duration for which the money is invested or borrowed, one can effectively determine the total interest accrued.

Using this formula ensures that the calculation is clear and methodical, as it directly relates each component to the interest generated. Other options do not accurately represent the standard method for calculating simple interest, as they either mix the terms incorrectly or do not apply the correct mathematical operations.
