Suppose you give 100 to a bank which pays you 5 simple interest at the end of every year. In this formula P is the principle amount of the loan R is the interest rate which is expressed as a percentage value and T is the number of periods in time.
T Time period in years When calculating simple interest by days use the number of days for t and divide the interest rate by 365.
R r 100 t Time Periods involved. The simple interest formula adds the principle amount with the total interest over a period of time. Input method reads user input as a string. After one year you will have 105 and after two years you will have 110.
