What the author says it does
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

Questions the author answers
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.
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. Calculated Fields Form also provides more powerful real-time calculation capabilities, which in Gravity Forms is limited to simpler field operations. Both offer conditional logic, multi-page forms, and payment integrations.
How does Calculated Fields Form compare to WPForms?
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.
What controls are included in the plugin?
The plugin provides a wide range of form controls including text fields, email, phone, numbers, currency, date/time pickers, time slot selectors, sliders, radio buttons, checkboxes, dropdown menus, file upload, signature, QR code reader, audio and video recording fields, calculated fields, page breaks, summary fields, and container controls.
