Certificate of Deposit (CD)

What is a Certificate of Deposit (CD) and how does it work?

A Certificate of Deposit (CD) is a banking product where you deposit a fixed amount for a predetermined time at a fixed interest rate. At maturity, you receive your original deposit plus interest. Early withdrawals usually incur penalties, making CDs a stable, low-risk investment for fixed returns.

A Certificate of Deposit (CD) is a savings product offered by banks and credit unions that requires you to deposit a set amount of money for a fixed term, ranging from a few months up to several years. In exchange, the institution pays you a guaranteed fixed interest rate, often higher than regular savings accounts. When the CD reaches maturity, you receive your initial deposit plus the interest earned.

How CDs Work

Banks and credit unions use CDs to secure cash for fixed periods, which helps them fund loans and other investments. For depositors, CDs offer a predictable return with minimal risk. Withdrawals prior to the end of the term usually trigger an early withdrawal penalty—commonly a few months’ worth of interest—which reduces your earnings. Once a CD matures, you can withdraw your funds without penalty or roll them into a new CD.

Benefits of Certificates of Deposit

  • Stability and Safety: Money in CDs at FDIC-insured banks or NCUA-insured credit unions is protected up to $250,000 per depositor, per institution, ensuring safety against loss.
  • Fixed Interest Rate: The interest rate is locked in for the entire term, insulating you from market fluctuations.
  • Higher Returns than Savings Accounts: CDs generally offer better interest rates compared to standard savings accounts.

Considerations and Strategies

  • Term Lengths: Typical CD terms range from 3 months to 5 years or longer. Longer terms typically offer higher rates but reduce liquidity.
  • Laddering: A strategy to manage liquidity involves buying multiple CDs with staggered maturity dates, allowing periodic access to funds without penalties while capitalizing on higher long-term rates. Learn more about laddering and diversification.
  • Comparing Rates: CD interest rates vary among institutions and over time. Shopping around can secure better yields.
  • Awareness of Penalties: Early withdrawal penalties vary but often equal 3 to 6 months of interest. Knowing these details helps avoid unexpected losses.

Typical Use Cases

CDs are well-suited for conservative savers who want to protect principal while earning fixed returns, people saving for future events (like a home down payment or education expenses), and those who want to diversify their cash holdings beyond liquid savings accounts.

Common Misconceptions

  • You cannot freely withdraw your money before maturity without penalty.
  • CDs do not benefit from rising interest rates during the term.
  • Not all CDs strictly outperform savings accounts in every economic environment.

IRS and Tax Implications

Interest earned on CDs is taxable as ordinary income and reported on IRS Form 1099-INT by the financial institution. For tax details, refer to the IRS Topic Number 403: Interest Received.
