What is a CD (Certificate of Deposit)?
A Certificate of Deposit (CD) is a fixed-term savings account offered by banks and financial institutions. You deposit a fixed amount of money for a specific time period, and in return, you earn interest at a fixed or variable rate.
Key Features of CD:
- Fixed investment period (e.g., 6 months, 1 year, 5 years)
- Guaranteed interest earnings
- Low risk investment
- Higher interest rates than regular savings accounts
However, your returns depend on:
- Initial deposit
- Interest rate
- Time period
- Compounding frequency
This is exactly what the Marcus CD Calculator helps you determine.

Compound Interest Formula Explained
The Marcus CD Calculator uses the standard compound interest formula:
Compound Interest Formula
A = P (1 + r/n)^(n × t)
Where:
- A = Final amount (maturity value)
- P = Principal (initial deposit)
- r = Annual interest rate (decimal)
- n = Compounding frequency per year
- t = Time in years
Interest Earned Formula
Interest = A − P
How Compound Interest Works
Compound interest means you earn interest on both:
- Your initial deposit
- Previously earned interest
This creates a snowball effect, where your money grows faster over time.
Example:
If you invest $10,000 at 5% interest compounded monthly for 5 years, your earnings will be significantly higher than simple interest.
Example Calculation Table
| Principal ($) | Rate (%) | Time (Years) | Compounding | Maturity Value ($) | Interest Earned ($) |
|---|---|---|---|---|---|
| 1,000 | 4 | 2 | 12 | 1,083.00 | 83.00 |
| 5,000 | 5 | 3 | 4 | 5,796.00 | 796.00 |
| 10,000 | 6 | 5 | 12 | 13,488.00 | 3,488.00 |
| 15,000 | 4.5 | 4 | 1 | 17,799.00 | 2,799.00 |
