Typically, interest is paid on deposits to savings accounts. Your savings will increase as a result of the interest you earn on money you save, particularly if you have a higher-interest savings account. Simple interest - is paid on some investments and does not take into account the interest that has been added to the account; rather, it calculates interest just on the original amount. These investments often have a slightly higher interest rate. Compound interest - is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods. Compound interest is the norm for savings accounts.
