What Is a Certificate of Deposit (CD)?

Unlike regular savings accounts, CDs usually offer:

In exchange, your money remains deposited for a set term such as:

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

At the end of the term, you receive your original deposit plus earned interest.

Understanding Compound Interest

Compound interest is one of the most powerful concepts in investing.

It means you earn interest on:

• Your original deposit
• Previously earned interest

The more often interest compounds, the faster your money grows.

Interest is added every month, increasing total earnings.

Interest grows every day, maximizing returns.

Even small differences in compounding frequency can significantly impact long-term savings.
