A money market deposit account, also known by the acronym “MMDA,” is a type of savings account offered by banks and other financial institutions. Although federally insured, it differs from traditional savings accounts by providing a higher rate of interest. Unlike other types of insured, high-interest accounts, money placed in a money market account is available to the account holder at any time instead of being held for a committed time period.

What are the Benefits of a Money Market Deposit Account?

In addition to being federally insured and providing higher interest rates, a money market deposit account also has several other benefits.

• Immediate investment opportunities – When using a money market account, investments can be made immediately in mutual funds, stocks and bonds.
• No withdrawal penalties – There are no penalties for withdrawing money from a money market deposit account, as there often are with IRA’s and other high interest investment accounts.
• Fast access to funds – Money can be withdrawn from money market deposit accounts using checks, and in some cases, debit cards. Although not the same as a traditional checking account, money is removed in a similar fashion.
• Choice of providers – Money market account providers include banks, brokerage and mutual fund companies. This means there is opportunity to shop around and find the best interest rate available.
• Convenience – These accounts make convenient places to hold money from recent investment sales and estate settlements, and to store money that will be used for upcoming investments.

What are the Disadvantages of a Money Market Deposit Account?

Although there are many benefits, there are also some disadvantages of money market deposit accounts.

• Limited transactions – Because a money market deposit account accrues higher interest than a typical checking or savings account, the number of transactions allowed per month is limited, usually to five or less.
• Higher balance requirement – In order to receive the highest interest rate, many financial institutions require that a minimum balance is maintained in the account at all times. Some banks require a minimum as low as $500, while others have much higher minimums.
• Interest rates vary – Interest rates on money market deposit accounts are not locked and may vary from institution to institution. In addition, the account may accrue the highest interest when the economy is stable, but fluctuate wildly during times of recession.

A money market deposit account is a good choice for retirees or investors that would like to store their money while earning a high interest rate, still maintaining instant access to funds and being insured against loss. For a long-term investment, other accounts may offer even higher interest, but they may be less secure. Many people choose a money market deposit account for the flexibility and security they provide.
