Discover offers CDs, and they're available online with no minimum deposit requirement

Yes, Discover Bank offers certificates of deposit (CDs). You can open one entirely online through Discover's website, and there is no minimum deposit amount — you can start with as little as $1. The interest rate you receive is fixed for the entire term you choose, which ranges from three months to five years.

Discover CDs work the same way as CDs at any other bank: you give the bank a sum of money for a set period, and in return they pay you a fixed interest rate. When your term ends, you get your original deposit back plus the interest earned. The main difference between Discover and traditional banks is that everything happens online, and you don't need to visit a branch or meet a minimum balance.

The rates Discover offers change daily based on market conditions. Because Discover is an online-only bank with lower overhead costs than brick-and-mortar banks, their CD rates are often competitive with or higher than rates at physical bank branches, though this varies depending on the term length and the current interest rate environment.

Key Takeaways

  • Discover CDs require no minimum deposit and can be opened entirely online through their website.
  • You choose a term length between three months and five years, and your interest rate stays the same for that entire period.
  • When your CD matures, you receive your original deposit plus all interest earned, and you can then decide whether to open a new CD or move the money elsewhere.
  • Discover's CD rates change daily and are typically competitive because the bank has no physical branches to maintain.
  • If you withdraw money before your CD matures, Discover charges an early withdrawal penalty that reduces your earnings.

How Discover's CD terms and rates work

Discover offers five standard CD terms: three months, six months, one year, three years, and five years. The longer the term, the higher the interest rate you typically receive — this is how banks compensate you for locking your money away for a longer period. A three-month CD will pay less than a five-year CD, but your money becomes available sooner.

The rate you receive is locked in on the day you open the CD and does not change, even if interest rates in the broader economy rise or fall. This means if you open a one-year CD at 4.50% and rates jump to 5.50% the next month, you still earn 4.50%. The trade-off is that you know exactly how much interest you will earn before you commit your money.

Interest on Discover CDs is compounded daily and credited to your account monthly. This means you earn interest on your interest, which slightly increases your total return over time. The exact amount depends on the rate and the term length.

Early withdrawal penalties and what happens when your CD matures

If you need to withdraw money from your CD before the term ends, Discover charges an early withdrawal penalty. The penalty amount depends on the term length: shorter-term CDs have smaller penalties, and longer-term CDs have larger ones. For example, a three-month CD might have a penalty of one month's interest, while a five-year CD might have a penalty of 18 months' interest. You should check Discover's current terms before opening a CD to see the exact penalty for the term you choose.

When your CD reaches its maturity date, Discover automatically renews it into a new CD with the same term length at the current rate, unless you tell them otherwise. You have a grace period (usually around 10 days) after maturity to withdraw the money or move it to a different product without penalty. If you do nothing during that window, the renewal happens automatically. This is important to remember: if rates have dropped significantly, you may want to move your money rather than let it renew at a lower rate.

Opening a Discover CD online

To open a Discover CD, you log into your Discover Bank account online or use the Discover mobile app. If you don't already have a Discover account, you create one by providing your Social Security number, date of birth, address, and other standard identification information. The entire process takes about 10 minutes.

Once you're logged in, you select the CD product, choose your term length, and enter the amount you want to deposit. You can fund the CD from an external bank account (which takes one to two business days to transfer) or from an existing Discover savings or money market account (which is when ready). You review the terms, confirm the interest rate, and complete the opening. Your CD begins earning interest when ready.

How Discover CDs compare to savings accounts and money market accounts

Discover also offers savings accounts and money market accounts, and the main difference is flexibility versus rate. A Discover savings account has no term — you can withdraw money anytime without penalty — but the interest rate is typically lower than a CD. A money market account usually offers a rate between a savings account and a CD, but also allows withdrawals (though there are limits on how many you can make per month).

If you know you won't need the money for a specific period and want the highest rate Discover offers, a CD is the right choice. If you might need access to your money sooner, a savings or money market account is more flexible, even if the rate is lower. Some people use a CD ladder — opening multiple CDs with different maturity dates — so that money becomes available at regular intervals without locking everything away for years.

FDIC insurance on Discover CDs

Discover Bank is FDIC-insured, which means your CD deposits are protected up to $250,000 per depositor, per account type, per bank. If you have a CD and a savings account at Discover, they are counted separately for insurance purposes, so you could have $250,000 in a CD and $250,000 in a savings account, and both would be fully insured. If you have multiple CDs at Discover, they are added together and count as one account type for insurance purposes.

This protection means that even if Discover Bank failed (which is extremely rare), your money would be protected by the federal government up to the limit. This is one reason people choose to bank with FDIC-insured institutions rather than keeping large sums in non-bank investments.

Frequently Asked Questions

Can I add money to a CD after I open it?

No. Once you open a CD, the deposit amount is fixed. You cannot add more money to that specific CD. If you want to deposit additional funds, you would need to open a separate CD. Some people open multiple CDs at different times or with different amounts for this reason.

What happens if I need my money before the CD matures?

You can withdraw it, but Discover charges an early withdrawal penalty that reduces your earnings. The penalty amount depends on your CD's term length. You should review the exact penalty before opening the CD so you understand the cost if your situation changes.

Are Discover CD rates better than other banks?

Discover's rates are competitive and often rank among the highest available, but rates change daily and vary by term length. You can compare Discover's current rates to other online banks and credit unions on rate-tracking websites. The "best" rate depends on which term you need and when you check.

Can I open a CD if I don't have a Discover account yet?

Yes. You can create a Discover Bank account and open a CD at the same time through their website. You'll need to provide identification information and fund the CD from an external bank account or with a wire transfer.

What's the difference between a CD and a high-yield savings account at Discover?

A CD locks your money for a set term at a fixed rate, while a savings account lets you withdraw anytime without penalty. Discover's CD rates are typically higher, but savings accounts offer flexibility. Choose a CD if you won't need the money for a specific period; choose a savings account if you want access without restrictions.
