Savings accounts allow individuals to accumulate money for future needs and wants. They provide easy access to funds while earning interest, though usually at a low rate. Interest can be simple or compound, with compound interest adding earned interest to the principal balance over time. Other savings options include CDs, money market accounts, US savings bonds, and IRAs, each with different features regarding access, penalties, and tax treatment. Proper financial planning is needed to meet savings goals based on timeframe, interest rates, target amounts, and calculating growth.
