CD Maturity Calculator
Calculate exact maturity dates, grace period windows, and projected balances for any certificate of deposit term.
Results
The CD Maturity Calculator computes the exact maturity date and the total balance available on that date. The output includes the principal plus compound interest, the grace period start and end dates, and the automatic renewal deadline.
Maturity Date Planning
Maturity date planning aligns CD expiration with specific financial milestones. Depositors who match term lengths to planned expenses avoid early withdrawal penalties and maximize earned interest.
How Maturity Dates Are Calculated
The maturity date equals the account opening date plus the CD term length. A 6-month CD opened on March 1 matures on September 1. A 12-month CD opened on March 1 matures on March 1 of the following year. Banks use calendar dates rather than business days, so maturity can fall on a weekend or holiday. When the maturity date falls on a non-business day, the grace period begins on the next business day.
Grace Period Mechanics
The grace period is a 7-to-14-day window after the maturity date during which the depositor decides the next action. There are 3 available actions during the grace period: withdraw the full balance (principal plus interest), renew the certificate at the current market rate, or transfer the funds to a different account type. No early withdrawal penalty applies during the grace period because the certificate has already matured.
Automatic Renewal
Automatic renewal occurs when the depositor takes no action during the grace period. The bank renews the certificate for the same term length at the prevailing market rate. The new rate may differ from the original rate. Depositors who prefer to shop for better rates across multiple institutions should set a calendar reminder before the maturity date to prevent unintended automatic renewal.

Non-Standard Term CDs
Some banks offer non-standard CD terms such as 7 months, 11 months, 13 months, or 17 months. These promotional terms are designed to fill specific deposit gaps and frequently carry higher-than-average APY rates. Depositors should compare non-standard term rates against standard terms to identify opportunities for higher returns with minimal additional commitment time.

Calculate MaturityFAQs
How do I calculate a CD maturity date?

What is a CD grace period?
A CD grace period is a window of 7 to 14 calendar days after the maturity date. During the grace period, the depositor can withdraw, renew, or modify the certificate without penalty.
What happens if I miss the CD grace period?
The certificate automatically renews at the prevailing market rate for the same term length. The new rate may be higher or lower than the original rate.
Can I set up automatic renewal on a CD?
Yes, most banks automatically renew CDs at maturity unless the depositor opts out during the grace period. The renewal rate is the bank's current posted rate.
