What is Simple Interest?
Simple Interest (SI) is the most basic method of calculating interest on a loan or investment. It is calculated only on the original principal amount using the formula: SI = P x R x T / 100, where P is Principal, R is Rate of interest per annum, and T is Time in years.
Where is Simple Interest Used?
Simple interest is commonly used in short-term loans, car loans, some personal loans, and certain types of bonds. It is also used in calculating interest for Treasury bills and other money market instruments. Unlike compound interest, the interest does not compound, making it more straightforward to calculate.
Simple vs Compound Interest
With simple interest, you earn or pay the same amount of interest each year. With compound interest, interest is added to the principal and subsequent interest is calculated on the new total. Over longer periods, compound interest significantly outgrows simple interest. For short-term calculations, the difference may be minimal.
