Find the amount of interest earned by $8000 invested at 5% annual simple interest rate for 1 year. To start a mobile dog-grooming service, a woman borrowed $2,500. If the loan was for two years and the amount of interest was $175, The annual percentage rate (APR) of a loan is the interest you pay each year represented as a percentage of the loan balance. For example, if your loan has an APR of 10%, you would pay $100 annually per $1,000 borrowed. This is different from compound interest, where interest is calculated on on the initial amount and on any interest earned. As you will see in the examples below, the simple interest formula can be used to calculate the interest earned, the total amount, and other values depending on the problem.

For the above calculation, you have $4,500.00 to invest (or borrow) with a rate of 9.5 percent for a six-year period of time. Note that, for any given interest rate, the above formula simplifies to the simple exponential form that we're accustomed to. For instance, let the interest rate r be 3%, compounded monthly, and let the initial investment amount be $1250. Then the compound-interest equation, for an investment period of t years, becomes: The formula to find the balance, B, of a continuously compounded interest account with interest rate, r, after a certain time, t, is given by To solve this problem, we need to know only the initial investment (P), our final balance (three times P) and the interest rate (expressed as a decimal), 0.019. The formula for simple interest is. where is the amount that's loaned to you, is the annual interest rate, and is the time (in years) interest accumulates. In this problem, and Plug these values in: So in three years, you will owe an interest of $192. The interest charged in case of simple interest remains fixed for all the year.
