There is no required amount to open the account or to keep in the account. Marcus does not have monthly maintenance fees. You start earning interest on anything over $1 in the high yield savings account.

Marcus offers very competitive interest rates on their savings account and CD accounts. The interest rates are competitive with other online-only accounts. They are much higher than your typical bank rates.

Many different term lengths of CDs are available. Marcus offers nine different CD term lengths from six months to six years. The longer the term, the higher interest rate you earn. All the CD interest rates are very competitive with other online-only banks.

The personal loans offered through Marcus do not have fees. The loans are a fixed-rate interest loan. You can borrow up to $40,000. These loans can be to consolidate debt or for home improvement projects. The loans range in length from 36 to 72 months.

Marcus only offers deposit accounts of CDs and a high yield savings account. Checking accounts, money market accounts, and business accounts are not offered.

Since Marcus does not offer checking accounts, you cannot transfer money between Marcus checking and savings accounts. The easiest way to deposit money into your Marcus savings account is to link to an external bank account. You can also send a wire or check. Marcus does not charge a fee to send or receive a wire transfer, but the external bank might.

Marcus does not offer an ATM or debit card for the high yield savings account. To access your money, you must transfer the money back into your external bank account. You can also request a wire transfer.

To open any CD with Marcus, $500 is required. That amount opens the CD and is the amount needed to start earning interest. The interest rates vary depending on the term length of the CD. The longer the CD term, the higher the interest rates.

The Primary savings account offers competitive interest rates. For the first $1,000, you earn over a six percent interest rate. Any amount over $1,000 earns a lower rate of 0.25 percent. Between the two rates, the account earns competitive interest rates. The Primary savings account is the account you must open to become a member of DCU.

You can open all DCU accounts online. You do not need to visit a branch location to open the accounts. To open DCU accounts, you must be at least 18 years old. You must provide a government-issued ID and Social Security Number. Your address, phone number, and date of birth are also required.

The highest amount required to open a DCU checking or savings account is only $5. To earn interest for some accounts requires a larger balance. The CDs require $100 or $500, depending on the CD. Jumbo CDs require $25,000. DCU accounts do not have monthly fees or a required amount to keep in the account to avoid a fee.

To open an account with DCU, you must become a member of the credit union. You become a member by opening the Primary savings account with at least $5. Once you open that account and become a member, you can open any other DCU account.

The DCU money market account has tiered interest rates. To earn the most competitive interest rates requires a balance of at least $100,000. Lower balances earn interest, just not the highest rate.

The Ltd. savings account requires a balance of $25,000 to earn any interest. Any balance over $25,000 earns the most competitive rate, but balances below do not earn any interest.

Only one withdrawal is allowed per month from the Ltd. savings account. For every other withdrawal, there is a fee of $25. To earn interest on this account requires a balance of $25,000. There is no required amount to open the account.
