Money market accounts offer high interest rates and liquidity, making them ideal for short-term savings. This calculator helps you estimate potential earnings from a money market account based on your deposit amount, interest rate, and term length.
What is a Money Market Account?
A money market account (MMA) is a financial product that combines the features of a savings account and a checking account. These accounts typically offer higher interest rates than traditional savings accounts and provide easy access to funds.
Key Features of Money Market Accounts
- High interest rates (often above savings accounts)
- FDIC insurance (up to $250,000 per depositor)
- Check-writing capabilities (some accounts)
- Debit card access
- Online and mobile banking features
Types of Money Market Accounts
- Traditional Money Market Accounts: Offer interest on balances above a minimum requirement
- No-Minimum Money Market Accounts: Allow you to maintain a zero balance
- High-Yield Money Market Accounts: Provide competitive interest rates
Important Considerations
While money market accounts offer attractive rates, they typically have monthly maintenance fees if your balance falls below the minimum requirement. Always review the terms and conditions before opening an account.
How to Use This Calculator
This money market calculator estimates your potential earnings based on three key factors:
- Initial Deposit: The amount of money you want to invest
- Annual Percentage Yield (APY): The annual interest rate offered by the money market account
- Term Length: The number of years you plan to keep the money in the account
Enter these values into the calculator on the right side of the page, then click "Calculate" to see your estimated earnings and growth over time.
Formula Used
Future Value = Initial Deposit × (1 + APY)ᵗᵉʳᵐ
Total Interest Earned = Future Value - Initial Deposit
Key Formulas
The calculator uses these fundamental financial formulas to determine your money market earnings:
Future Value Calculation
The future value of your money market account is calculated using compound interest:
FV = P × (1 + r)ⁿ
Where:
- FV = Future Value
- P = Principal (initial deposit)
- r = Annual interest rate (APY)
- n = Number of years
Interest Earned Calculation
The total interest earned is simply the difference between the future value and the initial deposit:
Interest = FV - P
Assumptions
- Interest is compounded annually
- No additional deposits or withdrawals during the term
- APY remains constant throughout the term
Example Calculation
Let's say you deposit $5,000 into a money market account with a 2.5% APY for 3 years. Here's how the calculation works:
Step 1: Calculate Future Value
FV = $5,000 × (1 + 0.025)³
FV = $5,000 × 1.0736
FV = $5,368.00
Step 2: Calculate Total Interest Earned
Interest = $5,368 - $5,000
Interest = $368.00
After 3 years, you would have $5,368 with $368 in interest earned.

Frequently Asked Questions

- Yes, money market accounts are typically FDIC-insured up to $250,000 per depositor, just like savings accounts.
