Turn a pricing rule into a formula inside WP Cost Estimation. This guide uses a painting estimate at €35 per m² with a 10% discount above 100 m², so you can check exactly what the generated calculation should do.
Use your own business rates. In this example, surface area is multiplied by €35. When the area is strictly greater than 100 m², reduce the whole painting subtotal by 10%. At exactly 100 m² there is no discount.
Create the surface-area input first. In the component whose price should use this rule, enable Price calculation and choose Use A.I. Name the existing input clearly in your instruction so the formula can use the right field.
Charge €35 per m². Above 100 m², apply a 10% discount to the whole painting subtotal.
Specify that this rule covers painting only, before tax, with no additional quantity multiplier. If you need a minimum fee, travel cost or extra options, give each rule and its order explicitly.
Check the referenced field, the comparison operator and the discount base. The output belongs in the plugin’s calculation editor. Do not paste a generic JavaScript example with invented field IDs. Save the component and open the form preview.
These are arithmetic checks for the example rule, before taxes and extras. Enter each area in the actual form and compare its painting subtotal.
80 m² × 35 € = 2 800 €
100 m² × 35 € = 3 500 €
120 m² × 35 € × 0.9 = 3 780 €Yes. Configure your provider in the plugin’s AI Settings. OpenAI and Anthropic are supported for text-based AI tools. API usage is billed by your provider separately from the plugin license. Optional image generation uses OpenAI.
