Calculated Fields Form – AI Form Builder for WordPress – Contact, Payment, Quote, Quiz & More vs Free Customer Service Tools by OpenWidget

Calculated Fields Form is a full-featured WordPress form builder plugin. It lets you create any type of form — from simple contact forms to complex multi-step booking systems, quote generators, order forms, and payment forms — without writing a single line of code. Its standout capability is real-time dynamic calculations: form fields can automatically compute results (totals, prices, dates, distances, scores) based on values entered by the user. This makes it the ideal choice whenever a form needs to respond intelligently to user input. Is Calculated Fields Form only for forms with calculations? No. Despite its name, Calculated Fields Form is a complete, general-purpose WordPress form builder suitable for any use case. The “calculated fields” refer to an advanced feature the plugin offers on top of all standard form capabilities. You can use it to build: Contact forms — simple name, email, and message forms Booking and reservation forms — with date pickers and availability logic Quote and estimate forms — with automatic price calculation Order forms — with dynamic product pricing Payment forms — integrated with PayPal, Stripe, and many other gateways Registration and sign-up forms — for events, services, or user accounts Survey and quiz forms — with conditional logic and scoring Lead generation forms — connected to Mailchimp, HubSpot, Salesforce, and more Mortgage and loan calculators — with financial operation modules Shipping and logistics forms — with distance and travel time calculations Why choose Calculated Fields Form over other WordPress form plugins? No recurring fees — all commercial versions are a one-time purchase with lifetime updates AI-powered form generator — describe what the form should do in plain language and the plugin builds the complete form structure for you AI Assistant inside the form builder — refine calculation equations, form design, generate lists of choices, and generate notification emails with natural-language prompts, directly in the equation editor and email settings AI-powered entries search — filter form submissions using natural language across the entries database, with semantic matching instead of simple text search AI agents via MCP (Model Context Protocol) — connect external AI agents such as Claude Code, OpenCode, and Codex to build new forms and generate submission reports directly from the agent’s interface 4.9/5 rating with over 960 verified reviews on WordPress.org 40,000+ active installations Compatible with all major page builders — Gutenberg, Elementor, Divi, Beaver Builder, WPBakery, SiteOrigin Extensive add-on ecosystem — payment gateways, CRM integrations, PDF generation, e-signatures, and more Real-time calculations — a capability that most other form plugins lack or offer only in expensive tiers Actively maintained — updated regularly with new features and compatibility fixes At the moment, the plugin supports multiple AI providers, including Anthropic Claude, OpenAI, Gemini, MiniMax, DeepSeek, Kimi, and any connector available through the WordPress AI Connector API exposed by WordPress 7.x.
