Do you write a blog? Own a car dealership? Or are otherwise involved in financial services? Then you should consider adding one (or all!) of my financial calculators to your website. They are all easy to install. And for now, they are all free. More below...»

Loan Calculator

What's a widget? What's a plugin?

If your website is built using WordPress use a "plugin". If your website is built using plain HTML/CSS/JavaScript use a "widget". It's that easy.

Note, if you have a WordPress site, and you want to install a calculator in a WordPress "widget area", you still download and use the "plugin". :-)

Both widgets and plugins are fully customizable. Click on the appropriate link below for all details.

Plugins for Sites Built with WordPress

Widgets for HTML Websites

And naturally all plugins and widgets come with full support. You can leave your questions at the bottom of any of the above linked pages.

  • Hi
    Have downloaded wordpress loan calculator, however it doesn’t appear to be responsive on mobile phone. The only bit responsive is the end of period drop down. Cant seem to enter the numbers on mobile phone?
    Please help

    • Does the loan calculator plugin on this page work for you? What browser and what cell? I have recently had a report of problems with Android, but not sure with what browser.

  • Hello Karl,
    Are those 8 widgets only suitable for a wordpress website or the full set of your financial calculators could be installed online?

  • Hi
    Im in the UK and im looking at setting the default option to Pounds from the initial page load and not having to use the selector at the bottom.

    Is this possible and how can i achieve it for the wordpress version.


    • Hi Andy, thanks for posting your question here. You didn’t mention which plugin you want to use. Here are the directions

      The calculators are designed for an international audience, and the user can pick the currency. based on the retirement savings plugin. Others will be similar, but file location and names will change (the edit is the same though).

      However, if you don’t mind making an edit, to the source code, you (the website owner) can change the currency. Here’s how to do it:

      In the plugin folder, there is a js folder. Should be here with default install:


      find this file:


      With a plain text editor, such as notepad open it up and search for this text:


      Should be around row 7. Change the “$” to whatever you need as the example below. Save, and refresh the webpage


      If you want the € on the right, replace ccy_r instead.

      This will change the plugin’s default for you

      The downside with this hack is, no one visiting the page will be able to set the currency to “$”. Or at least I don’t think they will be able to. I didn’t actually test that.

      Hope this works for you.

    • Hello, as with all WordPress plugins that are downloadable from, the source code is provided. It would be possible for you or someone else to translate the calculator. But as of now, I do not have a Spanish language version.

      • Tnx for your reply. Sincerilly, your plugin is the better that I found at this moment, you really have to translate to Spanish and other languages.

        • Alvaro, in principle, I agree that the site and plugins need to be translated. The issue, of course, is one of resources. I only have so much time. Even if I had volunteers provide translations, it takes a long time to work with them and to create the new pages. I still have calculators that need to be added to the site.
