Frequently Asked Questions
How is CD total earnings calculated ?
downward-arrow
Total CD earnings is calculated based on your initial deposit amount, the CD interest rate, the CD term, and the compounding frequency. The formula typically uses compound interest, which means your interest earns interest over time resulting in the CD’s annual percentage yield (APY). Use our CD earnings calculator to input your deposit, term, and APY to instantly see your total interest earned and final balance. This helps you estimate your exact return before you lock in your savings.
What’s the difference between APY and interest rate ?
downward-arrow
The interest rate is the base rate your certificate of deposit (CD) earns, while the APY (annual percentage yield) includes the effect of compounding interest over one year. The APY gives a more accurate picture of how much you’ll actually earn on your deposit. When comparing CD rates, always look at the APY instead of just the interest rate to understand the true return on your investment. Our CD interest calculator uses APY to show your expected earnings based on your CD term and deposit amount.
Does compounding frequency affect my CD returns ?
downward-arrow
Yes, the compounding frequency can significantly impact your CD returns. A CD that compounds interest daily will earn more over time than one that compounds monthly or annually, even if the interest rate is the same. The more frequently interest is compounded, the more you’ll earn on your original deposit assuming that interest stays in the CD until maturity.
Do You Offer Other Long-Term CD Rates?
downward-arrow

Yes, we offer a wide range of CD rates across both short-term and long-term durations to fit your savings strategy. You can explore options including:

These options give you the flexibility to choose the right term, whether you're building a CD ladder or maximizing long-term returns.

How do I compare CD rates and choose the best option?
downward-arrow

When comparing CD rates, focus on the APY (annual percentage yield) rather than just the interest rate, as APY reflects your true earnings including compounding.

To compare CD rates effectively, look at the APY and match it with your preferred term length. You can review current options like 6-month CD rates, 12-month CD rates, 24-month CD rates and longer terms 3-year CD rates, 4-year CD rates, and 5-year CD rates to see how rates vary over time.

Then, use the calculator above to estimate your total earnings based on your deposit, APY, and term—so you can quickly identify which option delivers the best return for your goals.
