The CFF plugin allows you to create both simple and professional forms. Its form builder includes dynamic calculated fields and many other controls.

Calculated forms list
Absolutely! The “Calculated Fields Form” plugin opens up a world of possibilities. Here’s a breakdown of what you can achieve:
Financial Calculations: Design forms that automatically compute totals, taxes, discounts, and other financial metrics.
Booking Forms: Seamlessly handle date operations, availability checks, and booking calculations.
Product Pricing: Dynamically calculate product prices based on user inputs or predefined rules.
Math Operations: Perform basic arithmetic, percentages, and complex mathematical functions.
Text Processing: Manipulate text fields, concatenate strings, and format data.
Date Operations: Handle date differences, age calculations, and time-related tasks.
Advanced Operations:
Distance Calculations: Compute distances between locations.
Chart Generation: Create charts dynamically based on form data.
Third-Party Service Integration: Call external APIs or services for real-time data retrieval.
And the best part? All resulting forms are mobile responsive, ensuring a seamless experience across devices.
The most remarkable aspect is that you don’t need to hire a developer to create forms. With basic knowledge, you can have professional forms in minutes.
The form builder is entirely visual, offering a wide selection of controls (Text fields, Numbers, Currency, Date/time, Slider control, Email, Radio buttons, Checkboxes, Container fields, Multi-page control, QR code reader, Recording, Calculated fields, and many others). This versatile toolkit empowers you to create customized forms effortlessly.
And its new AI assistant provides exceptional support for developing complex calculation formulas and designing custom forms with ease.
The “Calculated Fields Form” plugin includes integration with popular page builders:
For other editors, it is possible to insert the form into the pages via its shortcode. Each web form has an associated shortcode that allows you to insert it wherever you want.
[CP_CALCULATED_FIELDS id="1"]
“Calculated Fields Form” comes with dozens of predefined forms that you can select during the form creation process, or you can build new forms from scratch.
Calculated Fields Form Commercial
The free version of the “Calculated Fields Form” plugin provides essential functionality, including sending notification emails to the website owner with the form data, basic operations for use with equations, and core features such as customizing form design, setting up conditional fields, and modifying the form layout. More advanced distributions, Professional, Developer, and Platinum, come with additional capabilities such as sending copy emails to form users, integration with payment gateways and external services, controls for managing database connections (including links to external data sources like Google Sheets in CSV format), and a variety of complex operations. All commercial versions are available as a one-time purchase with lifetime access to plugin updates. ( https://cff.dwbooster.com/download )

Below, some possible formulas are included as examples, but the possibilities are endless.
With simple mathematical operations:
fieldname1 + fieldname2
fieldname1 * fieldname2
fieldname1 / fieldname2
fieldname1 - fieldname2
fieldname1 - fieldname2
With mathematical operations involving multiple fields and grouped fields:
fieldname1 * (fieldname2 + fieldname3)
With rounding operations. Round the result to two decimal places:
PREC(fieldname2 / fieldname3, 2)
There are infinite number of formulas that can be created using complex structures. For example, the following formula includes conditional statements:
(function () {
if (100 < fieldname3) return fieldname1 + fieldname2;
if (fieldname3 <= 100) return fieldname1 * fieldname2;
})();
For complex formulas/equations you must use the function format with return statement to return the result to the calculated field:
(function () {
var result = 0;
/* Your code here */
return result;
}) ();
One of the “Calculated Fields Form” strengths is the ability to use any valid JavaScript code to implement the equations/formulas.
However, the plugin includes a wide variety of operations and operators to simplify the development process.
Mathematical Operations and Operators
Operations for interacting with external services
Operations for handling URLs and query strings
In addition to the operation modules listed above, the Developer and Platinum versions of the plugin include additional modules:
Distance and Travel Time Operations
The plugin includes the shortcode [CP_CALCULATED_FIELDS_VAR] to generate JavaScript variables from parameters received by “GET” or “POST”, “SESSION” variables, or “COOKIES”:
[CP_CALCULATED_FIELDS_VAR name="..."]
In the shortcode, you must replace the “…” symbols with the name of the parameter or variable. The variables are created as properties of the cff_var variable. For example, in the [CP_CALCULATED_FIELDS_VAR name=”my_var”] shortcode, you can access the variable value from the equations by using cff_var[‘my_var’], or cff_var.my_var
For example:
[CP_CALCULATED_FIELDS_VAR name="varname"]
You can use the variables generated through the shortcode [CP_CALCULATED_FIELDS_VAR] in the formulas of the calculated fields: fieldname1*cff_var.varname
