How Money Market Accounts Work

Money market accounts are designed for short-term savings with liquidity needs. They typically offer higher interest rates than traditional savings accounts but may have restrictions on withdrawals and minimum balance requirements.

These accounts are often FDIC-insured up to certain limits, providing security for your deposits. The interest is usually compounded, meaning you earn interest on both your initial deposit and the accumulated interest.

Key Features

Higher interest rates than savings accounts
FDIC insurance (varies by institution)
Compounding interest
Liquidity (easy access to funds)
Potential restrictions on withdrawals

The Formula

The future value of a money market account with compound interest is calculated using the following formula:

A = P × (1 + r/n)^(n×t) Where: A = the future value of the investment/loan, including interest P = the principal investment amount (the initial deposit or loan amount) r = the annual interest rate (decimal) n = the number of times that interest is compounded per year t = the time the money is invested or borrowed for, in years

For example, if you deposit $1,000 at an annual interest rate of 2%, compounded monthly for 5 years, the calculation would be:

A = 1000 × (1 + 0.02/12)^(12×5) A ≈ $1,104.08

Worked Example

Let's say you want to calculate the return on a $5,000 deposit in a money market account with a 1.5% annual interest rate, compounded quarterly, for 3 years.

Principal (P) = $5,000
Annual interest rate (r) = 1.5% or 0.015
Compounding frequency (n) = 4 (quarterly)
Time (t) = 3 years

Using the formula:

A = 5000 × (1 + 0.015/4)^(4×3) A = 5000 × (1.00375)^12 A ≈ 5000 × 1.0456 A ≈ $5,228.00

In this example, you would earn approximately $228 in interest over 3 years.
