Calculators by Symmetry


Employees always asking questions about their paychecks? 

Calculators by Symmetry are payroll tax modeling calculators that are placed into your website. Each package, standard or premium, comes with our full collection of calculators and tools and is available as widgets or through an API. 

Unique to the product is the ability to completely customize. Do you want your calculator to be blue? Done. Want to preset a state for payroll purposes? Do it. Need to pass your employee data into the calculator via JSON? You got it.

You paste the widget code we give you into your site, along with a unique key, and your calculators are ready for use. If you select the API option, it's also a cut and paste job - but this offers the added benefit of being 100% stateless. Build an entire interface around it. Make it striped. Code some cool animations. Go crazy! 

The API performs calculations and returns the information in JSON data, which is displayed however you want. If you love the way our calculators already look, go for the widget. You drop it in and you're done. With either version, your payroll department can free up time by directing employees to your calculators. 

​Complete Customization

Change the background color, font color, style, or pre-set values with the widgets or use the API to build an unique interface.


​Full Set of Calculators

Each package - standard or premium - comes with our full set of calculators.


​Responsive Design

The widget and the API are both responsive, meaning your employees can access the calculators anywhere.
