What is a CD?
A certificate of deposit, or CD, is a deposit account that generally requires you to leave funds deposited for a specified term. In exchange, the institution pays interest according to the account terms.
How this calculator works
The calculator uses the stated annual percentage yield, or APY, to estimate growth over the selected term. APY is designed to reflect the annualized yield on the account.
Why APY matters
APY provides a standardized way to compare deposit account earnings because it reflects the annualized yield rather than displaying only the stated interest rate.
What this calculator assumes
This estimate assumes a fixed APY, no additional deposits or withdrawals, and that interest remains with the CD through maturity.
Early withdrawals
Many CDs impose an early-withdrawal penalty. The amount and method vary by institution and specific CD terms, so this calculator does not estimate early-withdrawal penalties.
Variable-rate and callable CDs
Some CDs may have rates that change during the term, and callable CDs may allow the issuer to end the account before the scheduled maturity date. This calculator is intended for a standard fixed-APY CD.
Important limitation
Actual bank calculations and account terms may differ. Review the CD disclosure for the maturity date, APY, early-withdrawal rules, renewal policy, and other applicable conditions.
