1. What is the Marcus CD Calculator?

The Marcus CD Calculator helps you estimate the growth of your Certificate of Deposit (CD) investment with Marcus by Goldman Sachs. It uses the compound interest formula to project your earnings based on current CD rates, principal amount, and term length.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

Where:

• \( A \) — Final amount including principal and interest
• \( P \) — Principal investment amount
• \( r \) — Annual interest rate (decimal)
• \( n \) — Number of compounding periods per year
• \( t \) — Time the money is invested for (years)

Explanation: The formula accounts for compound growth, where interest is earned on both the principal and accumulated interest.
