WS Form LITE – Drag & Drop Contact Form Builder vs Calculated Fields Form – AI Form Builder for WordPress – Contact, Payment, Quote, Quiz & More

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?
