Flexible WordPress forms with dynamic calculations
Calculated Fields Form is a full-featured WordPress form builder for creating forms that respond intelligently to user input. The Professional, Developer, and Platinum editions are commercial versions that combine general-purpose form building with real-time calculations for totals, prices, dates, distances, and scores.
Despite its name, the plugin is not limited to forms that contain calculations. You can use it for a simple contact form or build a more involved multi-step booking system, quote generator, order form, payment form, registration form, survey, quiz, or lead-generation workflow without writing code.
Paid capabilities for practical workflows
- Real-time calculations: Automatically calculate results from values entered by the user, including prices, totals, dates, distances, and scores.
- AI-powered form generation: Describe the form you need in plain language and generate its complete form structure.
- AI Assistant: Refine calculation equations, adjust form design, generate lists of choices, and create notification emails through natural-language prompts.
- AI-powered entry search: Filter form submissions across the entries database using natural-language queries and semantic matching.
- AI agents via MCP: Connect external agents such as Claude Code, OpenCode, and Codex to build forms and generate submission reports from an agent interface.
- Page-builder compatibility: Use the plugin with Gutenberg, Elementor, Divi, Beaver Builder, WPBakery, and SiteOrigin.
Use cases and integrations
Create booking and reservation forms with date pickers and availability logic, quote and estimate forms with automatic pricing, order forms with dynamic product prices, or payment forms connected to available payment gateway add-ons. Registration forms can support events, services, or user accounts, while surveys and quizzes can use conditional logic and scoring.
The add-on ecosystem extends the workflow with CRM connections to Mailchimp, HubSpot, and Salesforce, PDF generation, e-signatures, unique-value validation, iCal attachments, and file uploads to the WordPress media library. Payment integrations listed in the source include PayPal, Stripe, Revolut, Authorize.Net, Skrill, iDeal options through TargetPay or Mollie, PayTM, SagePay, Sage, eWay, Payrexx, and Spanish bank gateways.
How to get started
Install the selected commercial edition in your WordPress site, open the form builder, and choose the type of form you want to create. You can describe a form for the AI-powered generator or build it directly, then configure fields, equations, conditional behavior, notifications, and any required add-ons. Test the form with representative values to confirm that calculations and submission workflows behave as intended before publishing it.
Commercial editions
Professional, Developer, and Platinum are the paid editions of Calculated Fields Form. They are presented as one-time purchases with lifetime updates, giving you a choice of commercial plan while retaining the plugin’s broad form-building purpose and calculation-focused workflow.
