Formula Explained

The calculation for money market interest is based on the compound interest formula:

Where:

• A = Interest earned
• P = Principal amount
• r = Annual interest rate (in decimal)
• n = Number of times interest is compounded per year
• t = Time the money is invested for (in years)

For monthly interest calculations, we use t = 1/12 (one month) and n = 12 (monthly compounding).

Worked Example

Let's say you deposit $5,000 into a money market account with an annual interest rate of 2.5% that compounds monthly. Here's how the calculation works:

In this example, you would earn $10.42 in interest over the month, bringing your total balance to $5,010.42.

Key Factors to Consider

When using a money market interest calculator, consider these important factors:

• Minimum balance requirements: Some money market accounts require you to maintain a minimum balance to earn interest.
• Fees and penalties: Be aware of any fees associated with the account, such as monthly maintenance fees or penalties for withdrawals.
• Interest rate changes: Money market interest rates can change over time, so check for rate adjustments periodically.
• Tax implications: Interest earned on money market accounts is typically tax-exempt, but consult a tax professional for specific advice.
