How to Create a WordPress Price Calculation Form

Start from the plugin forms screen and open the AI wizard. Describe the business, the pricing variables, the expected steps, and the fact that the Property Size item will use a Price calculation formula.

For this guide, the prompt asks for a cleaning service calculator with package choice, property size, number of rooms, add-ons, frequency discounts, and a final summary.

After generation, return to the forms list and check that the calculator has a clear name. A descriptive name makes it easier to manage test forms, demos, and production calculators later.

In this example, the form is named Home Cleaning Price Calculator because the calculation model is tied to a cleaning service offer.

A good price calculation form should follow the way a buyer thinks. Start with the service package, then ask for variables that affect price, then show options, discount choices, contact fields, and a final summary.

This order keeps the calculation understandable because the visitor sees each pricing decision before the final estimate.

Open the item that should calculate the variable price, then open its Price tab and enable Price calculation. In this example, the Property Size slider uses a calculation formula to change the square-foot rate depending on the selected cleaning package.

The formula starts with the standard rate, then raises the rate when deep cleaning or move-in and move-out cleaning is selected. This is easier to maintain than creating duplicate fields for every package.

Use the Add a value and Add a condition controls beside the formula editor when referencing other fields. That way, the builder inserts the correct item references instead of forcing you to type item IDs from memory.

Create a WordPress page for the calculator and embed the form with the fullscreen attribute. This keeps the pricing flow focused and avoids distractions from the surrounding theme layout.

Use the form ID from the forms list. The example shortcode below uses the local demo form created for this guide.

Open the public page and start the form as a visitor. The first step should make the offer easy to understand and set the base price for the estimate.

For the cleaning calculator, Standard Cleaning starts at $80. Deep cleaning and move-in or move-out cleaning can use different base prices and different square-foot rates.

Move to the property details step and check that the square-foot price, bedroom quantity, and bathroom quantity produce a sensible subtotal.

In this example, the property size is set to 1,000 square feet. With the standard rate, that adds $120 before room and bathroom quantities are included.

Optional services are useful when the buyer may need extras but should not be forced into a larger package. Add-ons also make the final summary more specific for the business receiving the request.

The demo selects Inside Oven and Interior Windows. The total rises from $255 to $320 before the recurring-service discount is applied.

Recurring services often deserve a discount because the business can schedule them more efficiently. A select field can apply a percentage reduction after the subtotal is built.

Here, Weekly service applies a 15% reduction. The estimate drops from $320 to $272, and the summary later records the selected discount.

Before the final estimate, collect only the details that help the business respond: special requests, preferred date, files, or notes. Do not bury the pricing logic under too many non-pricing questions.

A short note explaining the calculation can also reduce confusion for users and clients who review the form later.

The final summary is where the calculator earns trust. It should show the selected package, calculated quantities, add-ons, discount, contact details, and final total in a way the customer and business can both understand.

In the demo, the final total is $272 after package price, property size, bedroom and bathroom quantities, selected add-ons, and the weekly discount.
