Certificate of Deposit (CD)

A Certificate of Deposit (CD) is a savings certificate with a fixed maturity date and specified fixed interest rate. It is a time deposit commonly offered by banks, thrift institutions, and credit unions.

- Maturity Date: CD terms range from a few months to several years. Early withdrawal may incur penalties.
- Deposit Insurance: In many countries, CDs are insured by government agencies (e.g., FDIC in the US) up to a certain amount.
Example
For instance, a bank might offer a one-year CD at an interest rate of 2%. If you invest $1,000, at the end of one year, you will receive $1,020, assuming no early withdrawal.
