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; }) ();
Operations and operators to use in equations/formulas
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
Create variables from parameters received by “GET” or “POST”, “SESSION” variables, or “COOKIES” to use in the equations
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
The complete list of parameters accepted by the variables shortcode is available at the following link: CLICK HERE

Highly recommend
By janetdawson on November 22, 2025
I've been using this for years now, mostly to create calculators and project planners. Our users are not techy but have no problem using the forms.
Great Plugin
By schuhmacherseb on November 3, 2025
Awesome Plugin. Great featues & functionality. 10/10
Love it!
By jeanneinlandproducts on October 29, 2025
Works very well and is a very important part of a few of our Woocommerce product pages!
Great features
By Charles (charlesrodmell) on October 24, 2025
Using the free and paid versions on various sites. So good. Especially the visual dependencies to hide lower parts of a form until action taken, for simplicity.
Tolles Plugin, bin begeistert
By ljndner on October 23, 2025
Ich benutze Calculated Fields auf unserer Vereinswebsite für verschiedenen Wettkampftabellen. Erst dachte ich, ich muss wohl ein eigenes Plugin schreiben. Doch dann fand ich Calculated Fields. Das Plugin erfüllt alle meine Anforderungen. Sogar komplexe Berechnungen und Abhängigkeiten lassen sich darstellen. Der Formularentwurf gelingt auch auf alle möglichen Anforderungen. Ganz toll finde ich auch, dass man dem Formular sagen kann, es soll ich die Feldwerte per Browser merken. Damit sind die letzten Werte von letzten Besuch im Formular vorhanden. Also ein ganz großes Lob und Dank an die Entwickler des Plugins. Hier sind wohl Profis am Werk!
The tool if you want to create complex calculators
By Atipa Pluemchai (hatthabasel) on October 15, 2025

Calculated Field Forms is Amazing!!!
By twolsey on October 13, 2025
I have been using CFF for many many years and rely on its' functionality and flexibility on a daily basis with all of my clients' software solutions. It is an amazing product that allows seamless connectivity to my client databases. It is also tremendously flexible and responsive with the mobile applications/forms I create with the software. I have also connected it to my Dropbox and to make.com easily via webhooks. Very helpful features. The support I have received is so helpful and also very timely.
I recommend CFF to anyone requiring an amazing software for web and mobile form solutions that connect easily to MySQL databases (and more) and to any form of additional automation workflows. Support is awesome.

Support is fantastic

Very quick and efficient!
Best calculator plugin, but...
By Ben Delarosa (bendelarosa) on September 3, 2025
The best Calculator-Plugin.
Hi,
my name is Ben. After trying out more than a dozen plugins, I finally settled on “Calculated Field Forms.”
Reason: Best performance and works with all other plugins.
My problem: I would like to see not only the names of the fields in the form, but also the prices before selection.
Example:
Product Bravo = $100.00
Product Charly = $150.00
Total = $250.00
All I see in the form is:
Product Bravo
Product Charly
Total = $250.00
Unfortunately, I can't find a solution when creating the form.
I can't find anything about this in the information either.
Perhaps there is a solution?
Thank you.
Regards
Ben
Awesome plugin and BEST support
By cme (cmaass) on August 17, 2025
This plugin is way better than you can imagine. It is so much more than just a mathematical calculation form. It has been a tremendous help to my site. And most importantly, the support is phenomenal. I have reached out for help several times over the years and they are ALWAYS on point. I receive replies from them the same day and usually a solution in less than 48 hours- every time! I highly highly recommend CFF.
