This tool calculates the interest you can earn from a Certificate of Deposit (CD) based on your initial deposit and the interest rate.
How to Use the Calculator
To use the CD Interest Rate Calculator, simply enter the required values in the provided fields and click the “Calculate” button. The results will appear in the results section below the form.
Explanation of the Parameters
- Initial Principal ($): The amount of money initially deposited in the certificate of deposit (CD).
- Annual Interest Rate (%): The annual interest rate earned on the initial principal.
- Number of Years: The total number of years the money is invested or left in the CD.
- Compounding Periods Per Year: The frequency with which the interest is compounded per year (e.g., monthly, quarterly, yearly).
How the Calculator Works
The calculator computes the future value of the initial principal based on the annual interest rate, the number of years, and the number of compounding periods per year. The formula used is:
Future Value = Principal * (1 + Annual Interest Rate / Compoundings Per Year)^(Compoundings Per Year * Number of Years)
Limitations
This calculator assumes that the interest rate remains constant over the investment period and that no additional deposits or withdrawals are made after the initial deposit.
