How to Compare the Return on a CD Vs. Money Market
Certificates of deposit and money market deposit accounts are different accounts offered at banks and other financial institutions. Certificates of deposit offer a fixed rate of interest and the money must be left in the account until it matures. Money market deposit accounts offer higher interest rates than a savings account but still offer similar liquidity, or access to your money. As of August 2009, both certificates of deposit and money market deposit accounts are insured for up to $250,000 per person.

Determine whether you can invest enough in the money market account to meet the minimum balance requirements, if any.

Tips & Warnings
To calculate the value of a certificate of deposit when it matures, use the following formula where A is the amount of money you put into the certificate of deposit, R is the interest rate, N is the number of times per year the interest is compounded and Y is the term of the certificate of deposit in years. Value at Maturity = A * (1 + R / N) ^ (Y * N)
Do not confuse money market deposit accounts with money market mutual funds. Money market mutual funds are not FDIC insured and are not as liquid as money market deposit accounts.
