What is a certificate of deposit? 

A Certificate of Deposit (CD) is a financial account that holds a fixed amount of money for a period of time — like six months, 12 months or five years — and the Bank will pay you guaranteed interest for holding the money.

Frequently Asked Questions

This page offers a list of Frequently Asked Questions (FAQs) and answers regarding Certificates of Deposit at Security National Bank.

How do I open a CD account?

To get started, set up an appointment or call us at (712) 277-6500. You can also apply online for a 14-month, 22-month or 30-month CD.

What is the difference between a CD and savings account?

CDs are a low-risk savings tool, and they generally pay a higher interest rate than a regular savings account. They also have a fixed interest rate, unlike savings accounts, which have variable interest rates that are subject to change.

Can I lose money in a CD account? 

No, CD accounts grow at a fixed rate over a set period of time called a term. The money is also FDIC insured up to allowable limits, making CD accounts among the lowest-risk investments that will not lose value. The only way you could lose money is if you make an early withdrawal from your CD. In this case, you would face a potential penalty (see below question).

How much do I need to open a CD?

All Security National Bank CDs require a minimum deposit of $1,000 to open an account.

Are there any additional fees for opening a CD? 

No, you will not be charged any fees when opening a certificate of deposit account and it will not affect your credit score in any way.

Can I open a CD online? 

Yes, you can select terms of 14, 22 or 30 months online. To select other terms, please visit one of our branch locations.

How much interest will I get on my CD?

How much interest you earn depends on how much you deposit, your term and your interest rates. See our current rates or use the calculator on this page to see how much you could earn at the end of each term.

Interest begins to accrue on the business day you deposit non-cash items (e.g. checks). You must maintain the minimum balance designated for each term in the account each day to obtain the disclosed annual percentage yield (APY). Simple interest is compounded and credited semiannually for terms of one year or longer. For terms of less than one year — simple interest is compounded and paid at maturity.

Can I add money to my existing CD?

No, you cannot add money to an existing account until its maturity date. However, you can open additional CDs anytime at Security National Bank. Contact us to learn more.

Can I withdraw my money before the CD term is up?

You can withdraw your money early, however there will be a penalty for withdrawal prior to the end of your CD term.

Term Penalties:

  • 91 days or less: The greater of 7 days interest or the accrued interest
  • 92 days to 1 year: 91 days interest
  • Over 1 year: 182 days interest

What happens when my CD matures? 

Once your CD matures, you will have a 10-day window to choose between three options: 

  1. Allow your CD to renew.
  2. Withdraw your money and open a different CD with new terms.
  3. Withdraw your money and put it into another account.

If you do not withdraw your money, Security National Bank will automatically renew your CD for the same term — although it may be at a different rate — until the Bank receives written notice that you no longer wish to renew the account. 

Contact us to learn more.

What does FDIC insured mean?

The Federal Deposit Insurance Corporation (FDIC) insures deposits for banks. Many types of bank accounts are FDIC insured up to $250,000. This protects your money in the event that a bank fails or closes, but only to that maximum amount. Most deposit accounts, such as savings and checking accounts, are FDIC insured. Many investment accounts are not.
