1. What is the CD Maturity Formula?

The CD maturity formula calculates the future value of a Certificate of Deposit investment based on principal amount, annual interest rate, compounding frequency, and time period. It helps investors estimate their returns from Guardian Savings Bank CD investments.

2. How Does the Calculator Work?

The calculator uses the CD maturity formula:

\[ A = P \times (1 + R / n)^{n \times T} \]

Where:

\( P \) — Principal investment amount (USD)
\( R \) — Annual interest rate (decimal)
\( n \) — Compounding frequency per year
\( T \) — Time period in years
\( A \) — Maturity amount (USD)

Explanation: The formula calculates compound interest by accounting for how often interest is added to the principal balance, which then earns additional interest.
