Investing wisely is a key component of financial planning, and having the right tools to calculate future values can help individuals make informed decisions. In this article, we’ll explore the construction of a financial calculator using HTML, CSS, and JavaScript, with a practical example to illustrate the calculation process. The goal is to determine the number of years it takes for an investment to reach a target amount, considering an initial investment, annual deposits, and an annual interest rate.

Example Scenario:

Let’s consider a scenario where an individual has \$33,556.25 in a brokerage account and plans to deposit an additional \$5,000 at the end of every future year. The target is to accumulate \$220,000 with an expected annual interest rate of 12%.

Input \$33,556.25 in the initial amount.

\$5,000 in the annual deposit field.

Interest rate: just 12 (12%) in the annual interest rate

and \$220,000 in Target Amount.

### Conclusion:

Building a financial calculator empowers individuals to make informed investment decisions. By understanding the formula and using web development technologies like HTML, CSS, and JavaScript, users can interactively calculate the number of years required to reach their investment goals.
