Please remember you do not need to start the formula using = and also you do not need brackets for multiplying operations, only use brackets where totally necessary.

How to embed calculator on my website?

To embed your calculator, please go to the Embed tab on the right side of the top menu above your calculator, right next to the green button Save a calculator. 

Every calculator has an embed code that looks like this, please see below, and you have two options to choose from - without or with an iframe.

<link rel="stylesheet" href="" />
<script src=""></script>
<div ng-app="calculoid" ng-controller="CalculoidMainCtrl" ng-init="init({calcId:64,apiKey:''})" ng-include="load()"></div>


This code is the same for every calculator except for this part:


CalcID stands for the unique calculator number that loads a specific calculator, in this calculator 64. No API key, as in the example above, loads calculator according to free membership. If you login or add manually your API key there, your calculator will be loaded according to your membership type and its permissions.

How can I adjust styling of my calculator?

While Calculoid offers a number of styling options, such as field and font colours and sizes, the best way to adjust styling of your calculator is through CSS of the website where you have your calculator embedded. Calculoid inherits styling from webpage where it is embedded. 

Does Calculoid work on Wix, Weebly, Hubspot,etc?

As long as you have access to HTML of your website, Calculoid can be embedded on your website. It is also adviced to have access to CSS for adjustment of styling. Our general advice is to embed any existing calculatorto make sure that calculator styling is not affected in a way that makes calculator unusable.
