**Introduction**

Calculating mortgage rates is a crucial aspect of the home-buying process, and having a reliable tool at your disposal can make this task more manageable. In this article, we’ll guide you through creating a user-friendly 10 Year Fixed Mortgage Rates Calculator using HTML and JavaScript.

**How to Use**

To use the calculator, enter the necessary details such as loan amount, interest rate, and loan term in the corresponding input fields. Click the “Calculate” button, and the result will be displayed instantly.

**Formula**

The formula used for calculating monthly mortgage payments 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 interest rate divided by 12).
- $n$ is the total number of payments (loan term multiplied by 12).

**Example**

Suppose you have a $200,000 loan amount with a 4% annual interest rate for a 10-year term. Using the formula:

$r=×4% =0.00333$

$n=10×12=120$

$M=200,000×((+)120−(+)120 )≈$1932.68$
