Prime Share is not a savings account—it's a share certificate issued by a credit union

Prime Share is a savings product offered by some credit unions, but it functions differently from a traditional savings account. It is a share certificate, which means you deposit money for a fixed period (usually three months to five years) and receive a set interest rate in return. During that time, you cannot withdraw the money without paying an early withdrawal penalty.

A savings account, by contrast, lets you deposit and withdraw money whenever you want with no penalty. The interest rate on a savings account can change at any time, and you have when ready access to your funds. Prime Share locks your money away and locks in a rate—which can be an advantage if rates are high, but a disadvantage if you need the cash before the term ends.

The name "Prime Share" is specific to credit unions that use it. Not all credit unions offer it, and the terms vary by institution. Before opening one, you need to understand what happens if you need your money early and whether the interest rate justifies tying up your funds.

Key Takeaways

  • Prime Share is a share certificate, not a savings account, and requires you to keep money deposited for a set term ranging from three months to five years.
  • You will pay an early withdrawal penalty if you need to access your money before the term ends, typically equal to several months of interest.
  • The interest rate on Prime Share is fixed for the entire term, so you know exactly what you will earn, unlike a savings account rate that can change.
  • Prime Share is only available through credit unions that offer it, and the terms, rates, and penalties differ between institutions.

How Prime Share works and what the penalties cost

When you open a Prime Share certificate, you agree to deposit a specific amount of money and leave it untouched until the maturity date. The credit union pays you a fixed interest rate on that deposit. At maturity, you receive your original deposit plus the interest earned.

If you withdraw the money before maturity, the credit union deducts an early withdrawal penalty from your earnings. The penalty is usually stated as a number of months of interest—for example, three months of interest or six months of interest. If your certificate was earning $50 in interest and the penalty is three months of interest, you lose $37.50 (three months of the $50 annual rate) and receive the rest.

Some credit unions state the penalty as a flat dollar amount instead. You need to ask your credit union what the exact penalty is before you open the account, because it varies. A penalty that costs you three months of interest on a small deposit might be only $5, but on a large deposit it could be $100 or more.

The key question is whether you can afford to leave the money alone for the full term. If there is any chance you will need it, a regular savings account is safer, even if the interest rate is lower.

Prime Share versus a regular savings account: when each makes sense

Choose Prime Share if you have money you will not need for several months or longer and you want to lock in a higher interest rate. Credit unions often pay more interest on share certificates than on savings accounts, so if rates are currently high, a Prime Share certificate can be a good way to earn more on money you are already planning to save.

Choose a savings account if you need to keep your money accessible, if you are not sure when you might need it, or if you want the flexibility to withdraw without penalty. Savings accounts also let you add money whenever you want, whereas a Prime Share certificate is a one-time deposit for a fixed amount.

Some people use both: they keep an emergency fund in a savings account and put longer-term savings into Prime Share certificates. This way, they have access to money if something unexpected happens, but they also earn a higher rate on money they know they will not touch.

What to check before opening a Prime Share certificate

Before you commit, confirm these details with your credit union in writing or through their website:

  • The minimum deposit required (some credit unions require $500 or $1,000 to open)
  • The term length options available (three months, six months, one year, etc.)
  • The interest rate for each term length
  • The exact early withdrawal penalty, stated in months of interest or as a dollar amount
  • Whether you can add money to the certificate after opening it (most do not allow this)
  • What happens at maturity—whether the funds automatically renew into a new certificate or return to your account

Interest rates on Prime Share certificates change over time and vary between credit unions. A rate that is attractive today may not be in a few months, so compare what your credit union is offering to what other institutions are paying before you decide.

FDIC and NCUA insurance on Prime Share

Prime Share certificates held at a credit union are insured by the National Credit Union Administration (NCUA), not the FDIC. NCUA insurance covers up to $250,000 per account holder per institution, the same limit as FDIC insurance for bank savings accounts.

This means your deposit is protected if the credit union fails. However, insurance does not protect you from the early withdrawal penalty if you need your money before the term ends. The penalty is a contractual cost you agreed to, not a loss due to bank failure.

If you have more than $250,000 to deposit, you can open multiple certificates at different credit unions to keep all your money insured. Each institution's insurance is separate.

How Prime Share compares to other credit union savings products

Credit unions typically offer three main savings products: a regular share savings account (similar to a bank savings account), a share draft account (similar to a checking account), and share certificates like Prime Share.

A share savings account has no term limit and no penalty for withdrawal, but the interest rate is usually lower than a certificate. A share draft account is for frequent transactions and typically earns little to no interest. Prime Share is for money you want to save for a specific period and earn a higher rate on.

Some credit unions also offer other certificate products with different names or slightly different terms. Ask your credit union whether Prime Share is their standard certificate product or whether they have alternatives that might suit your needs better.

What happens when your Prime Share certificate reaches maturity

When the term ends, your credit union will notify you of the maturity date. At that point, you have choices: you can withdraw the money, let it automatically renew into a new certificate at the current rate, or move it to a different account.

If the certificate automatically renews and you do not want it to, contact your credit union before the maturity date to request a withdrawal instead. If you miss the window and it renews, you will have another early withdrawal penalty if you need the money when ready.

The interest rate on the renewed certificate will be whatever the credit union is currently offering, not the rate you had before. If rates have dropped, your new rate will be lower. If rates have risen, your new rate will be higher. This is why it is worth checking what rates are available as your maturity date approaches.

Frequently Asked Questions

Can I withdraw money from Prime Share before the term ends?

Yes, but you will pay an early withdrawal penalty. The penalty is usually several months of interest. You receive your original deposit minus the penalty, so the longer you have held the certificate, the less the penalty costs you. Check your credit union's specific penalty before opening the account.

Is Prime Share FDIC insured?

No. Prime Share is insured by the NCUA (National Credit Union Administration) because it is held at a credit union, not a bank. NCUA insurance covers up to $250,000 per account holder per institution, the same protection level as FDIC insurance.

What is the difference between Prime Share and a money market account?

Prime Share has a fixed term and fixed rate; you cannot withdraw early without a penalty. A money market account typically allows withdrawals anytime, though some have limits on how many you can make per month. Money market accounts usually pay less interest than certificates but more than regular savings accounts.

Can I add money to my Prime Share certificate after I open it?

Most credit unions do not allow you to add money to an existing certificate. You would need to open a new certificate if you want to deposit additional funds. Ask your credit union about their policy before opening the account.

What happens if I need my money and cannot afford the early withdrawal penalty?

You will have to pay the penalty or wait until maturity. There is no way around it once you have signed the certificate agreement. This is why it is important to only put money into Prime Share that you are confident you will not need for the full term.
