What is Simple Interest?
Simple interest is a quick and easy method of calculating the interest charge on a loan or investment. It is determined by multiplying the daily interest rate by the principal by the number of days that elapse between payments.
Unlike compound interest, where interest is earned on both the principal and the accumulated interest, simple interest is only calculated on the original amount of money (the principal). It is commonly used for short-term loans, car loans, and consumer loans.
