Simple interest is a fundamental finance concept involving the interest on a principal sum over time. It's calculated using the formula SI = PRT, where 'SI' is the simple interest, 'P' is the principal, 'R' is the annual interest rate, and 'T' is the time in years. This method is typically used for short-term loans or investments. Understanding the difference between simple and compound interest is crucial for financial decision-making, as it affects the total interest accrued.

Formula for calculating simple interest
The formula for calculating simple interest is SI = PRT, where SI stands for the simple interest accrued over time
Variations of the formula
The formula for calculating simple interest can be rearranged to solve for any of the variables if the others are known, providing a comprehensive tool for solving financial problems
Simple interest can be applied in various financial contexts, such as calculating interest on loans and investments, using the formula SI = PRT
Simple interest is calculated based on the principal amount, the annual interest rate, and the time period
The annual interest rate must be converted to a decimal before performing calculations
The total amount, including interest, is determined by adding the simple interest to the principal, using the formula A = P + SI
Compound interest is calculated on the initial principal and the interest that has been added to it over time
Unlike compound interest, simple interest does not take into account the interest previously earned, resulting in a lower total amount of interest accrued over the same period
