Rates on CDs are typically higher. You can open a CD account if you wish to earn the greatest interest possible. You won't have access to the funds, though, until a specific timeframe has passed.
So, if you anticipate needing the money soon, a CD might not be the greatest option. Withdrawal costs are equal to many months' or a year's worth of interest.
You will be able to withdraw money up to six times per month thanks to money market rates, which provide you access to your money. They occasionally provide checks and typically have higher minimum balances.
However, as the rates are typically only slightly higher than those of standard savings accounts, you won't be making much money on interest. A money market account might not be the greatest option if you want to increase your interest earnings.
