1. What is the CD Calculator in Days?

The CD Calculator in Days calculates the future value of a Certificate of Deposit (CD) investment with daily compounding interest over a specified number of days.

2. How Does the Calculator Work?

The calculator uses the CD formula:

Where:

• \( A \) — Future value of the investment ($)
• \( P \) — Principal amount ($)
• \( r \) — Annual interest rate (as a decimal)
• \( d \) — Number of days the money is invested

Explanation: The formula calculates compound interest with daily compounding, where interest is added to the principal each day, earning interest on interest.

3. Importance of CD Calculation

Details: Accurate CD calculation helps investors understand the potential growth of their savings, compare different investment options, and make informed financial decisions about certificate of deposit investments.

4. Using the Calculator

Tips: Enter the principal amount in dollars, annual interest rate as a percentage, and number of days. All values must be positive numbers.
