**Introduction:** Planning for a 3-Year Certificate of Deposit (CD) investment involves understanding the potential future value. The 3-Year CD Rate Calculator assists in estimating the growth of your investment by considering key factors such as the principal amount, annual interest rate, compounding frequency, and the investment duration.

**Formula:** The calculator uses the compound interest formula to calculate the future value of the CD investment.

**How to Use:**

- Enter the initial principal amount.
- Input the annual interest rate as a percentage.
- Specify the number of compounding periods per year.
- Enter the investment duration in years.
- Click the “Calculate” button to estimate the future value of the CD investment.

**Example:** Suppose you have $10,000 to invest in a 3-Year CD with an annual interest rate of 5%, compounded quarterly. Input these values and click “Calculate” to see the estimated future value of your investment.
