CD Investment Calculator
Use this calculator to estimate the future value of your Certificate of Deposit (CD) investment and the total interest you'll earn over its term.
What is a Certificate of Deposit (CD)?
A Certificate of Deposit (CD) is a type of savings account that holds a fixed amount of money for a fixed period of time, and in return, the issuing bank pays interest. When you purchase a CD, you agree to keep your money deposited for a specific "term," which can range from a few months to several years. In exchange for locking up your funds, CDs typically offer higher interest rates than traditional savings accounts.
How Do CDs Work?
When you open a CD, you deposit a principal amount, and the bank agrees to pay you a specific Annual Percentage Yield (APY) for the duration of the term. The APY reflects the total amount of interest you'll earn over a year, taking into account compounding. At the end of the CD's term, known as the "maturity date," you can withdraw your initial deposit plus all the accumulated interest. If you need to withdraw your money before the maturity date, you'll typically incur a penalty, which often means forfeiting some or all of the interest earned.
Benefits of Investing in CDs
- Predictable Returns: The interest rate is fixed for the entire term, so you know exactly how much you'll earn.
- Low Risk: CDs offered by FDIC-insured banks (or NCUA-insured credit unions) are protected up to $250,000 per depositor, per institution, per ownership category.
- Higher Yields: Often offer better rates than standard savings accounts, especially for longer terms.
- Financial Discipline: The penalty for early withdrawal can encourage you to keep your savings untouched.
Drawbacks of Investing in CDs
- Liquidity Restrictions: Your money is locked up for the CD's term, making it less accessible than a regular savings account.
- Inflation Risk: If inflation rises significantly during your CD's term, the fixed interest rate might not keep pace, reducing your purchasing power.
- Opportunity Cost: You might miss out on higher returns if interest rates rise significantly after you've locked into a CD with a lower rate.
How to Use the CD Investment Calculator
Our CD calculator helps you visualize the growth of your investment. Simply enter the following details:

Example Calculation:
Let's say you invest $10,000 in a 3-year CD with an APY of 5.0%.
- Initial Deposit: $10,000
- APY: 5.0%
- Term: 3 Years
Using the calculator, you would find:
- Total Interest Earned: Approximately $1,576.25
- Total Value at Maturity: Approximately $11,576.25
This example demonstrates how your money can grow predictably over time with a CD.
