How Money Market Earnings Are Calculated
Money market earnings are calculated using the compound interest formula:
The calculator uses this formula to estimate your earnings. For example, if you invest $1,000 at 2% annual interest compounded monthly for 5 years:
Future Value = $1,000 × (1 + 0.02/12)^(12×5) = $1,104.08
Total Interest Earned = $1,104.08 - $1,000 = $104.08
Types of Money Market Accounts
There are several types of money market accounts available:
- Traditional Money Market Accounts (MMAs): Offer higher interest rates than savings accounts but typically require a higher minimum balance.
- Online Money Market Accounts: Often have lower fees and higher interest rates than traditional MMAs.
- Certificates of Deposit (CDs): Fixed-term deposits that offer higher interest rates but require you to leave the money invested for a set period.
- High-Yield Savings Accounts (HYSAs): Similar to savings accounts but offer higher interest rates, often with lower fees.
Each type of account has different features and requirements, so it's important to compare them before choosing the right option for your needs.

Frequently Asked Questions
What is the difference between APR and APY?
APR (Annual Percentage Rate) is the simple interest rate, while APY (Annual Percentage Yield) includes the effect of compounding interest. APY is always higher than APR for the same account.
How often are money market interest rates compounded?
Most money market accounts compound interest daily, but some may compound monthly or annually. The calculator allows you to select the compounding frequency.
What are the risks of money market accounts?
Money market accounts are generally low-risk, but there is some risk of loss if the financial institution fails. CDs carry the additional risk of early withdrawal penalties.
How do I choose the best money market account?
Consider factors like interest rates, fees, minimum balances, withdrawal limits, and your specific financial goals when choosing a money market account.
