3 Year Cd Calculator
A 3 Year CD Calculator is a financial tool designed to help users estimate the future value of their Certificate of Deposit (CD) after a fixed period of three years. A CD is a secure savings product offered by banks and credit unions where you deposit money for a fixed term in exchange for a guaranteed interest rate.
Unlike regular savings accounts, CDs lock your money for a specific duration, and in return, you earn higher interest. The 3-year CD is one of the most popular mid-term investment options for individuals looking for stable, low-risk returns.
This calculator helps you quickly determine how much your investment will grow over three years based on your principal amount, interest rate, and compounding frequency.

- Compounding: Monthly (12 times per year)
- Time: 3 years
Using the formula:
