P x R x T is the calculation for

The formula P x R x T is used to calculate simple interest, where P represents the principal amount (the initial sum of money), R is the annual interest rate (expressed as a decimal), and T is the time in years for which the money is borrowed or invested. This formula derives from the concept that simple interest is calculated only on the principal amount for the entire duration of the investment or loan, without any compounding.

Using this formula, you can easily determine the interest earned or paid by multiplying these three components. Simple interest is straightforward and is commonly used in various financial scenarios, such as loans and savings accounts, where the interest does not compound. Understanding this calculation is crucial for comprehending how interest accumulates over time in financial transactions.
