So you’ve finally got a little cash set aside for investing, Congrats! Now you need to learn how to invest your money so it works for you. You have found that there are many different ways to invest your savings to earn top dollar. But you’re leery on investing because you do not want to lose your nest egg. When investing you never want to invest more than you are wiling to lose. An almost risk free type of investment is a CD or certificate of deposit.

A CD is a type of timed savings account where you are not to liquidate or take cash out of the account for a certain period of time, called a term. When the term is up you can take your money out of the CD, this is called the CD’s maturity date. You are able to withdraw funds from a CD early, however there are consequences to this. You may not receive all the earned interest and you might not receive the full principal back as well. It is rarely a good idea to withdraw funds from a CD early unless you are in dire need of funds.

How Does It Work?

Understanding how a CD works is really pretty simple. Banks or Credit Unions offer CDs with different terms, which will earn interest on the funds while they are in the CD accounts. Once the maturity date is reached you can decide to cash out the CD or roll the principal and earned interest into a new investment account.

Before you decide to put your money into a CD it is important to know that you do not expect any major expenses to come up during the CD term. You do not want to need cash and not readily be able to access it or be penalized for doing so. Once you decide you want to invest in a CD, you need to decide what term is going to work best for your financial situation and investment needs or desires.

CD Terms

CDs come in a variety of terms. You can have a short term CD one month to six months. Most CDs are a minimum of a year. Typically the longer the term of the CD the better the earned interest rate on the investment. Standard CD terms are six month, one year, two years, and up to five or ten years. Some CDs require a minimum deposit, but not all. So even if you do not have a large amount of money to invest there is a right CD for you.

Types of CDs

Standard CD: The standard CD investment has a fixed term with a fixed interest rate. You deposit $X and after the term is up, you will have earned $X in interest. The rates will vary by institution.

Liquid CD: Also known as a No-Penalty CD: This is like a standard CD however because you are able to retrieve your funds the investment during the term it will earn a lower interest rate.

Variable CD: The Variable CD investment has a fixed term, but the earned interest rate will vary. The interest rate would change due to different market conditions that would cause the rate to increase or decrease. This investment has more risk than the standard CD because the end earned interest could be less. You would not lose the principal amount like you could in other investment tools, so you principal is still safe and earning interest, your just may no earn as much interest as you had hoped.

Jumbo CD: It is exactly what it sounds like, if you have a large amount of money to invest, you could consider a Jumbo CD as it earns more in interest than a standard or variable CD.

Step Up CD: A Step Up CD has a step up plan for the interest rate on the CD. During specific times during the term of the CD the interest rate will increase. A Step Up CD Provides investors with a higher earned interest over the course of the CD term.

Trade Up CD: Also known as a Bump Up CD. If CD rates have increased a Trade Up CD offers investors a one-time chance to unlock their current CD interest rate and lock in at the current rate.

Callable CD: A Callable CD is where the issuing institution can call back (terminate the CD) after a protected period of the investment ( say 6 months ) but before the CD’s maturity date of 1 year. It can be good or bad depending on what happens in the market. Unless you plan on tracking CD rates on a routine basis this type of CD may not be the best option for you, especially if you are just starting to invest in CDs.

Pros and Cons of Investing in CDs


  • Secure investment – you do not have to worry about the principal investment being depleted.
  • If you do not renew or move your funds into a new account, CDs have an auto-renew feature. The bank will reinvest your funds into a standard CD; this will keep your investment earning interest for you if you forget to roll your investment.
  • You know, give or take, what your earned interest will be after maturity of the CD.


  • If you do not renew your CD the institution may auto-renew your funds into a standard CD, which if that wasn’t your plan you have now lost time to choose your own investment. Be sure to stay on top of your CD maturity dates.
  • You do not readily have access to your money. If you end up needing money during the CD term, if you go to withdraw funds you will likely lose interest earnings and possibly principal for the early withdraw.
