Cost Calcul’ator


The Cost Calcul’ator plugin is a useful tool for creating custom forms to calculate a price estimate for your product or service.



The Cost Calcul’ator plugin allows you to create unlimited forms using various layout options and different field types (select, slider, switcher etc.). For each field used you can set a specific price that will change depending on the user’s interaction and choices. The Cost Calcul’ator plugin is very useful to show to your user an estimate cost of your product or service and it will encourage the user to contact your company for more information.

The plugin does not only have a Cost Calcul’ator inside it but it also has a “Projects” module through which you can insert infinite Projects and show to your clients your Portfolio works, the single project page containing custom fields (budget, author, duration, year of creation, etc ..) and an automatic layout template optimized to show your project in the best possible way.


The plugin is developed with Ajax technology in order to improve the user experience and increase interaction performance with your customer, in this way the price calculation will be in real time and the page load will not be required to see the final price . To create the effects of Slider, select and switcher we used the native WordPress JQuery UI library, this for don’t introduce new libraries and keep the code always lighter and faster in order to increase the performance as much as possible and avoid any incompatibility with plugins and external themes.

The plugin sets up easily. We had an issue with Contact Form 7 not working only in Cost Calculator and the support team worked diligently to troubleshoot and resolve a few setup errors made on our end.

A pity you cannot insert decimal 'prices' to work-a-round using percentages. For example I need to calculate 2% for a commission on selling price object. And it would also be better if it would show thousand seperator (, or .). Need improvement.
