Money Market Cd Calculator

Money market certificates of deposit (CDs) offer a way to earn interest on your savings while locking up funds for a fixed period. This calculator helps you determine how much you'll earn from a money market CD based on your deposit amount, interest rate, and term length.

How to Use This Calculator

To calculate your money market CD earnings:

Enter the principal amount (the initial deposit) in the "Initial Deposit" field.
Select the annual interest rate offered by your financial institution.
Choose the term length of your CD (typically 3 months to 5 years).
Select whether the interest is compounded annually, quarterly, monthly, or daily.
Click "Calculate" to see your projected earnings and total value.

The calculator will display your total earnings and the future value of your CD, taking into account the compounding frequency you selected.

Formula Used

The future value of a money market CD is calculated using the compound interest formula:

Compound Interest Formula

Future Value = P × (1 + r/n)^(n×t)

Where:

P = Principal amount (initial deposit)
r = Annual interest rate (in decimal)
n = Number of times interest is compounded per year
t = Time the money is invested for, in years

Earnings are calculated as Future Value minus the initial deposit.

Worked Example

Let's say you deposit $5,000 in a money market CD with a 2.5% annual interest rate, compounded quarterly, for 2 years.

Principal (P) = $5,000
Annual interest rate (r) = 2.5% or 0.025
Compounding frequency (n) = 4 (quarterly)
Time (t) = 2 years

Plugging these values into the formula:

Calculation

Future Value = 5000 × (1 + 0.025/4)^(4×2)

= 5000 × (1.00625)^8

= 5000 × 1.050945

= $5,254.73

Your total earnings would be $5,254.73 - $5,000 = $254.73.

CD vs. Savings Account Comparison

Money market CDs typically offer higher interest rates than regular savings accounts, but with the trade-off of locking up your funds for a fixed period. Here's a comparison:

Feature	Money Market CD	Savings Account
Interest Rate	Higher (typically 1-5%)	Lower (typically 0.1-1%)
Access to Funds	Locked for term (early withdrawal may incur penalties)	Immediate access
Minimum Deposit	Often higher ($1,000-$5,000)	Lower ($1-$100)
Term Length	Fixed (3 months to 5 years)	No term requirement
Best For	Short- to medium-term savings goals	Everyday spending and liquidity needs

Note

Interest rates and terms vary by financial institution. Always check current rates and terms before opening a CD.
