How to add Calculator to a Onepage landing page

Embed Calculator on Onepage

01

Create a Calculator widget for Onepage on Common Ninja

First, create a Onepage Calculator widget on Common Ninja. On the widgets catalog, find the Calculator and enter the Editor.

02

Save the Calculator widget

When you're done creating the Calculator widget, click on the Save Changes button at the right top corner of the editor. If you don't have an account on Common Ninja, you'll have to register first.

03

Copy the Calculator Embed Code

When you're ready to add the Calculator widget to your Onepage landing page, click the Add To Website button at the top bar of the Editor. On the window that opens, click the Copy Icon to copy the widget embed code. In the next steps, you will paste this code into your Onepage landing page.

04

Paste the code to your Onepage website’s HTML field.

Next, go to your Onepage landing page editor and find the HTML field. It is most likely in the form of an HTML/Code widget or module which you can find on the Onepage’s editor. Add it to your page, and paste the Calculator Embed Code you’ve copied before to the HTML field. Save and update, and that’s it, you should have Common Ninja’s Calculator widget on your Onepage landing page.

05

Alternative Method 1: Through the HTML option in the text’s editing area.

If you can't find the HTML/Code widget or module, there's another way to put Common Ninja’s Calculator widget on your Onepage widget. You can just add the code to a special HTML section in the text editor.

06

Alternative Method 2: Add it directly to your Onepage landing page’s HTML code.

If you're having trouble finding a widget or a special part in your text editor where you can add the Embed Code, you can try a different way to add the Calculator widget to your Onepage landing page. You can do this by putting it straight into your Onepage landing page's HTML code.

Why Use This Widget

Use the Calculator widget when you want to help visitors quantify value, cost, or outcomes based on their own inputs. Interactive calculators are powerful tools for simplifying complex decisions such as pricing estimates, savings, ROI, loans, or nutrition. Users enter their situation and receive immediate, personalized results, which increases trust in your expertise and keeps them engaged. This is useful for financial services, SaaS pricing, agencies, health, and education. By giving clear numeric answers, you reduce guesswork and shorten the path from curiosity to action. Calculators often become high intent entry points for leads who have already seen how your solution fits their case.
