Before you lock in a fixed rate, run through this quick checklist to make sure you are squeezing the most from your savings while keeping liquidity and insurance coverage intact.
A Certificate of Deposit (CD) is a time deposit offered by banks and credit unions that pays a fixed interest rate for a specific term. CDs are considered low-risk investments because they're typically insured by the FDIC up to $250,000.
CD terms typically range from 3 months to 5 years, with longer terms generally offering higher interest rates. The interest rate is locked in when you open the CD and remains fixed throughout the term.
How often interest is calculated and added to your principal. More frequent compounding results in higher returns.
Typically 3-12 months of interest if you withdraw funds before maturity. Always check penalty terms before investing.
APY (Annual Percentage Yield) includes compounding effects and gives you the true annual return on your investment.
CD interest is taxable as ordinary income in the year it's earned, even if you don't withdraw it.
Investing in multiple CDs with different maturity dates to balance liquidity and higher interest rates.
Consider your liquidity needs before investing in CDs. While they offer guaranteed returns, your money will be locked up for the entire term unless you pay early withdrawal penalties.

Our CD calculator uses standard compound interest formulas to provide accurate projections based on the information you enter. The results assume the interest rate remains constant throughout the term and that no early withdrawals are made. Actual returns may vary slightly due to bank-specific terms and conditions.
APY (Annual Percentage Yield) includes the effects of compounding and represents the actual annual return you'll earn. APR (Annual Percentage Rate) is the simple interest rate without compounding. For CDs, APY is more important as it shows your true earnings potential including compound interest.
More frequent compounding results in higher returns. Daily compounding will earn slightly more than monthly, which earns more than quarterly or annual compounding. However, the difference is usually small for typical CD terms and rates. Our calculator lets you compare different compounding frequencies to see the impact.
Early withdrawal from a CD typically results in a penalty, usually equivalent to 3-12 months of interest depending on the CD term and bank policies. Our calculator includes an option to estimate this penalty. The penalty is deducted from your principal if you haven't earned enough interest to cover it.
Yes, CD interest is taxable as ordinary income in the year it's earned, even if you don't withdraw it. You'll receive a 1099-INT form from your bank if you earn more than $10 in interest. Our calculator includes an option to estimate after-tax returns based on your tax rate.
Minimum deposits vary by bank and CD type, typically ranging from $500 to $10,000. Some banks offer no-minimum CDs, while others require $25,000 or more for premium rates. Higher minimums often come with better interest rates, so it's worth shopping around.
Longer terms typically offer higher rates but lock up your money for more time. Choose based on your liquidity needs and interest rate outlook. If you expect rates to rise, shorter terms give you flexibility to reinvest. If rates are high or declining, longer terms lock in current rates.
CD laddering involves buying multiple CDs with different maturity dates. For example, you might buy 1, 2, 3, 4, and 5-year CDs. As each matures, you reinvest in a new 5-year CD. This strategy provides regular access to funds while maintaining higher long-term rates.
Online banks typically offer higher CD rates than traditional banks due to lower overhead costs. Both are FDIC insured up to $250,000, so safety is comparable. Consider factors like customer service, ease of account management, and whether you need branch access when choosing between online and traditional banks.
Most traditional CDs don't allow additional deposits after opening. However, some banks offer "add-on CDs" that permit additional deposits during the term, though these typically offer lower initial rates. If you want to make regular deposits, consider a high-yield savings account or money market account instead.
