Understanding Deposit Rates

A deposit rate, often referred to as the Annual Percentage Yield (APY) or interest rate, is the percentage of your initial deposit that you will earn over a period, typically one year. This rate is offered by financial institutions on savings accounts, certificates of deposit (CDs), and other deposit products. A higher deposit rate means your money grows faster, allowing you to reach your financial goals sooner.

When comparing deposit products, it's crucial to look beyond just the advertised rate. Consider the compounding frequency (how often interest is calculated and added to your principal) and any fees or minimum balance requirements. APY takes compounding into account, providing a more accurate picture of your potential earnings.

For example, if you deposit $1,000 into an account with a 3% APY, after one year, you would have earned $30 in interest, bringing your total to $1,030. If the interest compounds more frequently, the actual amount earned might be slightly higher due to earning interest on previously earned interest.
