Key Terms

Initial Investment: The amount of money you're putting into the money market.
Annual Interest Rate: The percentage yield you expect to earn annually.
Investment Period: The length of time your money will be invested.

Money Market Basics

Money markets are financial markets where short-term borrowing and lending take place. Common money market instruments include:

Money market funds
Certificates of deposit (CDs)
Treasury bills
Commercial paper

Money Market Funds

Money market mutual funds invest in short-term debt instruments with maturities of less than one year. They typically offer higher yields than savings accounts but with slightly higher risk.

Certificates of Deposit (CDs)

CDs are time deposits offered by banks and credit unions. They offer fixed interest rates for specific terms, typically ranging from one month to five years.

Simple Interest Formula

For money market investments, simple interest is often used to calculate earnings:

Future Value = Initial Investment × (1 + (Annual Interest Rate × Investment Period))

Total Interest = Future Value - Initial Investment

Calculator Formulas

The calculator uses the following formulas to determine your money market investment results:

Future Value Calculation

The future value of your investment is calculated using the simple interest formula:

Future Value = P × (1 + (r × t))

P = Initial Investment
r = Annual Interest Rate (as a decimal)
t = Investment Period (in years)

Total Interest Calculation

The total interest earned is simply the difference between the future value and the initial investment:

Total Interest = Future Value - P

Example Calculation

Let's say you invest $10,000 at an annual interest rate of 2.5% for 3 years. Here's how the calculation works:

Initial Investment	$10,000
Annual Interest Rate	2.5%
Investment Period	3 years
Future Value	$10,765.63
Total Interest Earned	$765.63

Using the formula: Future Value = $10,000 × (1 + (0.025 × 3)) = $10,765.63
