Alright, let’s build your first calculator. I’m going to walk you through this step-by-step because honestly, the interface might look a bit different than what you’re used to (in a good way!).
After you activate the plugin, you’ll see a new “Calculators” menu in your WordPress admin. Click on Dashboard first – it’s worth checking out. You’ll see your stats (which will be zero for now, obviously), and some quick action buttons.
Click the big “Add New Calculator” button. You ready? Let’s go!
First things first – the plugin uses a tabbed interface. Think of it like filling out a form in stages. You’re starting on the Basic tab.
Give your calculator a name. Something descriptive like “Custom T-Shirt Calculator” or “Lawn Care Quote Calculator” – whatever makes sense for your business.
Now click over to the Formula tab. This is where you set up how the calculator actually calculates prices. You’ll configure your base price and how different field values affect the final price.
This is the fun part! Click on the Fields tab and you’ll see where you actually build your calculator.

Last tab! This is where you control publication settings and behavior options for your calculator.

Notice something missing? Category Assignment isn’t in this Settings tab – it’s actually back in the Basic Info tab under “Assignment Strategy”! We’ll cover all the details about connecting your calculators to products and categories in the next section: Connecting Calculators to Your Products.
Hit that Save Calculator button and you’re done! Your calculator is now ready to assign to products.
