Terms (short and simple)

  • The widget is free for any website, including commercial sites.
  • Please keep the small "by NetPayMeter" credit line under the calculator.
  • The widget does not set cookies or show ads, and it does not collect what visitors type. Inputs are sent only to calculate the result.
  • Results are estimates, not tax advice. See how we calculate.

Questions

Will the widget slow down my page?

No. The script loads asynchronously after your page, and the calculator lives in an isolated container, so it cannot change your site's styles.

Do I need to update it when tax rates change?

No. The calculations run on NetPayMeter, so your embed always uses the current year's federal, FICA and state rules.

Can I change the size or colors?

The calculator fills the width of the space you put it in (up to 680px). Need something different? Contact us.
