Money market account rates have been falling due to Federal Reserve rate cuts. It’s important to compare rates to maximize earnings. The national average MMA rate is 0.58%, but some accounts offer 4% APY. Consider opening an account now to take advantage of high rates while they last.

The amount of interest earned in a money market account depends on the annual percentage rate (APY). With an average rate of 0.58%, a $1,000 deposit would grow to $1,005.82 after one year. Opting for a 4% APY account would result in a balance of $1,040.81, including $40.81 in interest.

Higher deposits in a money market account lead to greater earnings. For example, with a $10,000 deposit in a 4% APY account, the total balance after one year would be $10,408.08, resulting in $408.08 in interest.
