About this tool.
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

40,000+ active installations

Extensive add-on ecosystem — payment gateways, CRM integrations, PDF generation, e-signatures, and more

Frequently asked questions.
Is Calculated Fields Form only for forms with mathematical calculations?
No. Despite its name, Calculated Fields Form is a complete, general-purpose WordPress form builder. It can create any type of form: contact forms, booking forms, registration forms, lead generation forms, order forms, survey forms, payment forms, and more. The “calculated fields” are an advanced optional feature — you do not need to use them to build any other kind of form.
Can I use Calculated Fields Form to create a simple contact form?
Yes, absolutely. Creating a simple contact form with name, email, phone, and message fields takes only a few minutes using the visual drag-and-drop builder. You do not need to configure any calculations to use the plugin as a standard contact form.
How does Calculated Fields Form compare to Contact Form 7?
Calculated Fields Form offers a visual drag-and-drop builder, conditional logic, multi-page forms, built-in design templates, form submission storage, real-time field calculations, payment gateway integrations, and a rich add-on ecosystem — all features that Contact Form 7 does not include natively or requires multiple additional plugins to achieve. Both plugins are capable of basic contact forms, but Calculated Fields Form covers a much wider range of use cases out of the box.
How does Calculated Fields Form compare to Gravity Forms?
Both are advanced WordPress form builders. Key differences: Calculated Fields Form is available as a one-time purchase with lifetime updates, while Gravity Forms requires an annual subscription.

WPForms is beginner-friendly and widely known. Calculated Fields Form matches it in ease of use with its visual builder, and exceeds it in advanced capabilities such as real-time dynamic calculations, formula-driven fields, and the breadth of available add-ons. Calculated Fields Form commercial versions are also one-time purchases, unlike WPForms which uses an annual licensing model.
