Compound Interest (study island)
Chat with our AI personalities
Simple interest is interest that is calculated only on the amount of unpaid principal on a loan. Such interest is not added to the value of the loan but is tracked separately. Compound interest is interest that is calculated on the total of unpaid principal and accumulated interest on a loan. The difference is in simple interest there is no interest charged on accumulated interest while in compound interest there is interest charged on accumulated interest.
With compound interest the interest amount is added to the principle and then earns interest as well. This is usually expressed as an annual percentage rate (APR). Simple interest is not added to the principle and does not earn further interest and is used rarely.
"Compounded annually" means that the interest is added once a year.
Interest is a certain amount of money added on top of what you already have. For example: If you had £1000 in your bank account, and the bank added 5% interest, you would gain £50 free from the bank for keeping that £1000 in your bank.
