Calculating mortgage payments is a crucial aspect of financial planning, especially for those seeking a 30-year loan. To simplify this process, we present a user-friendly mortgage calculator built using HTML and JavaScript.

**How to Use**

**Formula**

The formula for calculating the monthly mortgage payment is:

$M=P(+r)n−r(+r)n $

Where:

- $M$ is the monthly mortgage payment,
- $P$ is the loan amount,
- $r$ is the monthly interest rate (annual rate divided by 12 and multiplied by 0.01),
- $n$ is the total number of payments (loan term in years multiplied by 12).

**Example**

Let’s consider a $300,000 loan with an annual interest rate of 4.5% over 30 years.

$M=300,000×(+)360−(+)360 $
