Calculate Certificate of Deposit earnings at maturity. Compare CD rates and terms to find the best return for your deposit with guaranteed interest.
Certificates of Deposit offer guaranteed returns with FDIC insurance, making them one of the safest places to park cash. With CD rates in 2026 ranging from 4% to 5.5% depending on the term, this calculator compares different CD terms and compounding frequencies to maximize your earnings.
Certificates of Deposit (CDs) are time deposits offered by banks and credit unions that provide a fixed interest rate in exchange for locking your money for a specified period. CDs are among the safest savings vehicles available, with FDIC insurance up to $250,000 per depositor. They offer higher interest rates than regular savings accounts in exchange for limited access to your funds. This calculator helps you project your earnings at maturity and compare different CD terms and rates to find the best option for your financial situation.
Result: $10,000 in a 12-month CD at 5.00% APY: Interest earned over 1 year: $500. Total at maturity: $10,500. If compounded daily (5.12% APY): interest = $512.70, total = $10,512.70. The $12.70 difference from daily vs monthly compounding is small for short terms.
