Figuring out the percent different between two numbers is something I have to do often. Embarrassingly, I have to think about how to do it for a minute. I can always come up with the correct answer, but it takes me longer than I think it should.

So instead of waiting to get smarter, I just created this little WordPress plugin and a custom WordPress widget, shown here.

  • This WordPress custom plugin consists of the following files.

    Your percentager.php file should look like this.

    With the percentager custom WordPress plugin installed and activated, let’s add it to a post. You activated it right? If not, do that before continuing.

    To add the percentager custom WordPress widget to a post or page, you have to install AMR Shortcode Any Widget. Do that.

    Once you have the AMR Shortcode Any Widget installed and activated, go to Appearance -> Widgets. There you will now see “Widgets for Shortcodes.” You should also see the Percentager widget. Drag Percentager onto the “Widgets for Shortcodes” box.

    Now Percentager is available to be included in a posts and pages.

    Create a post and add this to the body in Text mode.
