Certificate of Deposit: Definition, Advantages & How to Invest in CD

A certificate of deposit (CD) is a type of savings account that offers a fixed interest rate and is provided by banks and credit unions for a specific period of time. Certificate of Deposit offers a higher interest rate than traditional banks, this interest rate is fixed as long as the funds remain untouched for the agreed term. The high interest rate serves as an incentive for giving up the ability to withdraw funds. 

If you have funds lying in the bank without yielding any interest, then you should check out some of the advantages of having a Certificate of Deposit.

Advantages of Certificate of Deposit

Certificate of Deposit is a great option for those looking to save money for a long period of time and earn a higher interest on it without the risk of investing it in stocks or keeping it in a traditional account with low to no interest. By understanding the advantages of a CD, you can be better informed about the risks and rewards it offers for your financial goals.

1. Safety

Certificates of Deposit are safe and insured by the Federal Deposit Insurance Corporation(FDIC). Unlike stocks and other volatile assets you are assured of a fixed return on your funds. 

2. Higher Rates

Compared to traditional bank accounts, CDs typically have a higher interest rate. Though the difference is that traditional savings accounts have flexible withdrawals, with little to no interest. This can be sorted out by choosing a CD that offers flexible withdrawals and interest.

3. CD Laddering

CD laddering involves opening multiple CDs with different terms to create a staggered investment approach. So instead of putting all your funds into one account for a period of time, you can divide them into different accounts with different terms and withdrawal periods.

4. Guaranteed Returns

CD is non-volatile, meaning you can predict the amount of money you’d be receiving at the end of the term as the Annual Percentage Yield(APY) is fixed. With a Certificate of Deposit calculator, you can insert the amount you have saved and your APY to have an estimate of the amount your funds will yield.

For example, if you have a 4-year CD term with a savings of $3,000 and earn an APY of 1.02%, by the end of your CD term you’d have about $3,124 in your CD.

5. No Monthly Maintenance Fee

There are no monthly maintenance fees with Certificate of Deposits. Unlike traditional savings accounts that may charge you a fee for monthly maintenance, you get to keep all your interest in a CD.

6. Early Withdrawal Option

CDs have the option of early withdrawal, though it comes with penalties like loss of interest and extra charges depending on the financial institution and CD type. For example, the No-Penalty CD allows for early withdrawal without penalties and offers flexibility while still earning interest.

7. Variety

There are different types of CDs available to choose from. Banks, credit unions and brokerage firms offer different CD options that suit your financial goals.

How to Invest in Certificate of Deposit (CD)

To invest in a Certificate of Deposit, you need to open an account. Opening a CD account is similar to that of any standard bank deposit account, the difference being the agreement you sign on paper or digitally. Ensure you compare CD options of various banks and credit unions before signing. After that, you’d need to take the following into consideration;

1. CD Term

Keep in mind the minimum deposit requirement of the CD before opening an account. This amount varies depending on the financial institution. While some banks have a minimum balance requirement, others don’t require any to open a CD account. Although, a typical traditional CD requires a deposit of $2,500. A jumbo CD for instance requires a larger minimum deposit usually around $100,000 or more.

3. Interest Rates

CDs usually come with higher interest rates compared to traditional savings accounts, that are usually fixed from the start. The interest rate most times depends on the bank or credit union, CD term and interest rate overtime. Research on the interest rates of multiple financial institutions and their CD terms.

4. Financial Institution

Banks and credit unions offer CDs with varying terms and interest rates. Research on the best CD term and interest rate that suits you from different financial institutions. Also, the minimum required amount for opening a CD account largely depends on each institution. Shop around and compare notes to see which financial institution has the best rates and terms.

5. Monitor and Renew

Once you open a CD account, keep an eye on it to determine when it’s matured so you can renew or roll over to a new CD and get a better interest rate.
