**Formula**

The formula for calculating the future value of a 5-year CD ladder is:

$FV=P×(1+r/n_{nt}$

Where:

- $FV$ is the future value,
- $P$ is the principal amount (initial investment),
- $r$ is the annual interest rate (decimal),
- $n$ is the number of times interest is compounded per year, and
- $t$ is the number of years.

**Example**

Suppose you invest $10,000 with an annual interest rate of 3.5%, compounded quarterly. After 5 years, the future value ($FV$) can be calculated as follows:

$FV=10000×(1+0.035/4_{×}$

**FAQs**

**Q: How often is interest compounded?**

A: Input the number of times interest is compounded per year in the “Compounded per Year” field.

**Q: Is the interest rate in percentage format?**

A: Yes, enter the annual interest rate in percentage format (e.g., 3.5 for 3.5%).
