Creating a Loan Payment Estimator using HTML - A Step-by-Step Guide

I'm in the process of creating a new website with godaddy.com and am struggling to code a calculator for customers to determine their payments. The calculator must include fields for Loan Amount, Loan Length in Months, Interest Rate, and Monthly Payment. I'm particularly stuck on calculating the Monthly Payment due to code placement issues. I need help generating an HTML code for this payment estimator on godaddy.com.

I've tried analyzing various pages for inspiration, used an html generator, and reached out to several individuals in my network without success.

This is the current code snippet I have:

<html><div class="wpb_wrapper"><center><form method="POST" name="calc">
<table border="0" width="60%">
<tbody>
<tr>
<th bgcolor="#FFFFFF" width="50%">Data Entry</th>
</tr>
<tr>
<td bgcolor="#F7F7F7">Loan Amount</td>
<td align="right" bgcolor="#F7F7F7">$<input id="amount" max="100000000" min="1" name="loan" size="10" type="text" /></td>
</tr>
<tr>
<td bgcolor="#F7F7F7">Loan Length in Months</td>
<td align="right" bgcolor="#F7F7F7"><input name="months" size="10" type="text" /></td>
</tr>
<tr>
<td bgcolor="#F7F7F7">Interest Rate</td>
<td align="right" bgcolor="#F7F7F7">%<input max="10000000" min="1" name="rate" size="10" type="text" value="10" /></td>
</tr>
<tr>
<td bgcolor="#F7F7F7">Monthly Payment</td>
<td align="right" bgcolor="#F7F7F7"><em>Calculated</em> <input name="pay" size="10" type="text" /></td>
</tr>
<tr>
<td align="center" bgcolor="#FFFFFF"><input type="reset" value="Reset" /></td>
<td align="center" bgcolor="#FFFFFF"><input type="button" value="Calculate" /></td>
</tr>
</tbody>
</table>
</form>
<p><span style="font-size: xx-small;"> "Enter only numeric values (no commas), using decimal points where needed." <br /> "Non-numeric values will cause errors." </span></p>
  </center></div></html>

There are no error messages, but I can't seem to calculate the monthly payment.

Answer №1

What you possess is a pure snippet of HTML code, which lacks the capability to perform any calculations on its own.

However, if your goal is to have a basic loan calculator, there is no need to start from scratch. There are numerous free pre-made calculators that can be easily integrated into your HTML code.

Approach 1: Utilizing an HTML embed code.

One such example of a free calculator can be found at :

You can insert this code into your html file:

<div style="width:185px; text-align:center;">
    <p style="text-align:center;">
       <a href="https://www.mortgagecalculator.biz" target="_blank">
           <img src="https://www.mortgagecalculator.biz/img/mlogo.gif" border="0" alt="Mortgage Calculator.biz."/>
       </a><br/>
       <iframe src="https://www.mortgagecalculator.biz/c/variables.php?loan=258678&rate=4.1&years=30" frameborder="0" width="185px" height="240px" scrolling="no"></iframe><br/>
       <a href="https://www.mortgagecalculator.biz/c/free.php" target="_blank"><font size="1" color="#000000">HTML Mortgage Calculators</font></a>
    </p>
</div>

The drawback of using an embed code is its reliance on an external website for the calculator's functionality. If that site experiences downtime, your calculator will also be affected.

Approach 2: Incorporating code directly into the html file:

A more reliable option is to integrate the actual calculator code within your HTML file. Look for freely available code online, ensuring to seek permission from the author before use.

For reference, here is a link to some code:

While HTML alone lacks the ability to perform calculations, you can achieve this by mastering javascript (numerous helpful tutorials are available online).

Once you have a strong grasp of javascript and understand how to create functions and manipulate element content, you'll be able to carry out these calculations.

To execute a javascript function upon clicking a button, simply include this code:

<button onclick="function();">Button text</button>
