This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.



This plug-in provides an opportunity to automatically integrate calculator. This way you don’t need to place the code manually, all you need to do is authorize access from the uCalc account and choose an already made calculator from the list.

uCalc is a service that helps you create and maintain calculators to estimate services and delivery costs as well as build booking, review, feedback, and event registration forms. No special knowledge and operational fees are required. You can create a calculator by just dragging the blocks and putting together simple formulas like A+B=C. You are provided with the embed code that needs to be added to a website powered by any platform. The built-in calculator is edited through the service.

The builder has the following benefits:

  • Ready-to-use templates and a collection of elements: a slider, button, drop-down list, checkmarks, contacts collection, date picker, etc.

  • Completed orders notifications are sent to the owner or manager of the website via email or SMS

  • Results with the opportunity to apply a promo code are sent to clients via email or SMS

  • Design customization: background and text colors, fonts and color customization of the elements

  • Display of several results, for example, with and without a discount

  • Recognition of any currency and measure (weight, size, volume, product unit)

  • Option to illustrate every element

  • Widgets on the website automatically adapt for smartphones and tablets

Уважаемые разработчики, пожалуйста, жалейте чужое время, укажите в описании плагина, что бесплатно калькулятором можно пользоваться только 14 дней + ссылку на тарифы. п.с. Комментараии в блогах хоть разнообразьте, видно же что заказаны.

The designer helped us to arrange reception of applications from clients and to remove the general problem connected with a spam. When there are many forms on the site, every month there are a lot of applications, and along with them, third-party advertising of spam bots. Previously, our forms received a lot of spam, but now it’s no more, thanks to uCalc. We had to redo some forms, but we are very satisfied with the result.
