What is a Certificate of Deposit?

A certificate of deposit (CD) is a financial product that allows you to deposit money for a fixed period in exchange for interest payments. Terms typically range from three months to five years; generally, the longer the term, the greater the exposure to interest rate risk. Larger initial deposits or longer investment durations often yield higher interest rates. CDs are considered low-risk investments with lower returns compared to stocks, but historically, their interest rates have been more favorable than those of savings accounts and money market accounts.

CDs are subject to taxes as income in the U.S., unless held in tax-deferred accounts like IRAs or Roth IRAs. For more information on these accounts, you can refer to our IRA Calculator or Roth IRA Calculator.

The term "certificate of deposit" originated from a time before electronic transactions, when financial institutions issued physical certificates to document deposits. This practice has largely been replaced by electronic record-keeping today.

FDIC Insurance

One of the key features of CDs in the U.S. is their protection by the Federal Deposit Insurance Corporation (FDIC). CDs from FDIC-insured banks are insured for up to $250,000, ensuring that if a bank fails, your funds are secure up to this limit. For those looking to invest more than $250,000, purchasing CDs from multiple FDIC-insured banks can provide full insurance coverage. Credit unions offer similar protections through the National Credit Union Administration (NCUA).

How to Purchase CDs

CDs are offered by various financial institutions, including large banks. Because interest rates can vary significantly, it's essential to shop around and compare annual percentage yields (APY) and maturity periods. The process of buying a CD is straightforward: you'll need to make an initial deposit and choose a term. Be aware that different banks may have different minimum deposit requirements, and some brokers may charge fees for their services.

When you "buy" a CD, you’re essentially lending money to the bank, which uses those funds for various purposes, including re-lending to others. The interest rates offered on CDs are influenced by a range of factors, including the federal funds rate.

History of CDs

The concept of a certificate of deposit dates back to European banks in the 1600s, where depositors received receipts for their funds, which the banks would then lend to merchants. To encourage depositors not to withdraw their funds prematurely, banks began paying interest for the designated holding period. This laid the groundwork for the modern CD.

A significant development for CDs occurred after the stock market crash of 1929, which highlighted the need for regulation in banking. The FDIC was established to protect depositors, providing a safety net for investors holding CDs.

How to Use CDs

CDs can serve multiple purposes in a financial strategy, including:

Withdrawing from a CD

CDs are intended to be held until maturity. Early withdrawals typically incur penalties, which can vary based on the length of the CD and the issuing institution. In some cases, it may make financial sense to pay the penalty in a rising interest rate environment to reinvest in higher-yielding options.

CD Ladder Strategy

While longer-term CDs offer higher returns, they also lock up your funds for extended periods. A CD ladder is a strategy that mitigates this drawback by utilizing multiple CDs with staggered maturity dates. For example, you might invest in three CDs with terms of one, two, and three years. As each matures, you can choose to reinvest the principal and interest into a new CD or access your funds. This strategy provides flexibility and can help take advantage of rising interest rates.

APY vs. APR

It’s important to differentiate between annual percentage yield (APY) and annual percentage rate (APR). Banks generally use APR for debt accounts, while APY is relevant for interest-accruing accounts like CDs. APY reflects the total interest earned over a year, including compounding, making it a better representation of actual returns compared to APR.

Compounding Frequency

The frequency of compounding can impact the total returns on your investment. Generally, the more frequently interest compounds, the greater the return. For more details, consider using our Compound Interest Calculator.
