What Is a Certificate of Deposit (CD)?

A Certificate of Deposit (CD) is a savings product offered by banks and financial institutions where you deposit money for a fixed period of time and earn guaranteed interest. Unlike regular savings accounts, CDs usually offer higher interest rates because your funds remain locked for a specific term.

Common CD terms include:

• 6 months
• 1 year
• 3 years
• 5 years
• 10 years

At the end of the term, also known as the maturity date, you receive your original deposit plus accumulated interest.

Example of CD Calculator Usage

Let’s look at a real-world example.

Example Scenario

• Initial Deposit: $10,000
• Annual Interest Rate: 5%
• Term: 5 Years
• Compound Frequency: Monthly

Estimated Results

• Final Balance: $12,833.59
• Interest Earned: $2,833.59
• Total Growth: 28.34%

This means your original $10,000 investment could grow by over 28% during the 5-year period.

Understanding Compound Interest

Compound interest is one of the most powerful concepts in personal finance. Instead of earning interest only on your original deposit, you also earn interest on previously earned interest.

This creates exponential growth over time.

Example of Compound Frequency Impact

Yearly Compounding

Interest is added once per year.

Monthly Compounding

Interest is added 12 times per year.

Daily Compounding

Interest is added every day, resulting in slightly higher returns.

The more frequently interest compounds, the larger your final balance becomes.
