What You Get...

Great Features & Flexibility

All of these calculators are ad-free & keep your visitors on your site to continue the real estate buying process.

Work Across Any CMS & Programming Language

The calculators install as an HTML inline frame (or iframe), so they will work with sites that use any sort of CMS (Wordpress, Joomla, Drupal, Blogger, Typepad, MovableType, ExpressionEngine, custom CMS tools & smarty templating, etc.) & sites programmed in any web language (eg: PHP, ASP, ASPX, Coldfusion, Ruby on Rails, Python, etc.). The embed code includes set width and height settings that are easily adjustible if you want to modify the look and feel.


You can insert our calculator into your sidebar or footer by using the built in widget feature. One of the default widgets is Text, allowing you to paste in arbitrary HTML code like our above calculator options. Select your sidebar or footer area, select the text widget option & drop it into that menu, drop our above code into that widget, then click save.

The other option would be to embed it within an HTML page to make a page focsed specifically on offering the calculator. If you embed our calculator inside of a Wordpress post or page, make sure to do either of the following:

  • when editing the page or post click on the "text" option (rather than the "visual" option) so you can paste HTML into it
  • disable the Wordpress rich text editor
    (checkbox setting at then hit save)

Real Estate Agent & Broker Friendly

Some widely known real estate listing aggregation sites like Zillow and Trulia offer free widgets which then link into their large portals, which then outrank REALTORS® in search engines like Google, Bing, and Yahoo! Search on local search queries:

As an independent real estate agent, you most likely work in a relatively small area, whether it's the little town you live in, or the San Antonio metro area, which is small relative to the country. But sites like Zillow and Trulia are accessible to anyone anywhere in the country, including those people who may be moving to your local area.

By including a backlink to its own listings in your city, Zillow is basically horning in on your local search action. And it's not just the link itself, but the text that is linked, which is called anchor text. When this text is optimized, it helps to target specific searches. In this backlink, the optimized anchor text is: "Homes for sale in San Antonio," meaning it's meant to target people searching for that specific item with those specific words.

Our site's content is strictly focused on helping people buy homes — we do not compete against local real estate agents by publishing geo-focused real estate listings.

We can't, don't & won't try to push you down the search page unlike the big guys.

International Friendly

While the full-page & extended calculators include United States (US) based defaults on PMI, taxes & closing costs, the basic calculator was designed to be friendly to all international markets. It does not contain any specific currency units or region-specific features, such that you don't have to worry about US-specific charges in Canada or a Dollar symbol in the UK.

Security & Encryption Come Standard: HTTPS Implementation

Our site uses a Let's Encyrpt security certificate to load our content in a secured manner. This means when you embed our widget codes in your site, they are embedded in a secured manner. Our widgets work in any HTTP or HTTPS website. And, more importantly, you keep your client's information secured!

You're in Great Company

Many REALTORS®, real estate brokers & home builders leverage our calculators to add functionality to their websites, helping them sell more homes.



Commercial Loans

Most of the above calculators cater to residential mortgages. Here is embed code for our commercial mortgage calculator. If you need embed code for any of our other calculators, just send us an email and we will create a version for you.
