## Formula:

The formula for calculating the maturity value of an 18-month CD is:

$Maturity Value=Principal Amount×(1+nAnnual Interest Rate )_{nt}$

Where:

- $Principal Amount$ is the initial amount invested.
- $Annual Interest Rate$ is the interest rate per compounding period.
- $n$ is the number of times interest is compounded per year.
- $t$ is the number of years the money is invested.

## How to Use?

**Enter Principal Amount**: Input the initial amount you are investing in the 18-month CD.**Specify Annual Interest Rate**: Enter the annual interest rate offered by the CD.**Compounding Frequency**: Indicate how often interest is compounded per year (e.g., quarterly, monthly).**Calculate**: Press the calculate button to determine the maturity value of your investment.

## Example:

Let’s consider an example:

- Principal Amount: $10,000
- Annual Interest Rate: 2.5%
- Compounding Frequency: Quarterly

\text{Maturity Value} = $10,000 \times \left(1 + \frac{0.025}{4}\right)^{4 \times 1.5}

\text{Maturity Value} \approx $10,254.45

So, the maturity value of the 18-month CD in this example would be approximately $10,254.45.
