How to add Calculator to a Squarespace store

Embed Calculator on Squarespace

01

Create a Calculator plugin for Squarespace on Common Ninja

First, create a Squarespace Calculator plugin on Common Ninja. On the plugins catalog, find the Calculator and enter the Editor.

02

Save the Calculator plugin

When you're done creating the Calculator plugin, 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 plugin to your Squarespace store, 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 plugin embed code. In the next steps, you will paste this code into your Squarespace store.

04

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

Next, go to your Squarespace store 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 Squarespace’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 plugin on your Squarespace store.

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 plugin on your Squarespace plugin. You can just add the code to a special HTML section in the text editor.

06

Alternative Method 2: Add it directly to your Squarespace store’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 plugin to your Squarespace store. You can do this by putting it straight into your Squarespace store'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.
