Embed calculators for free

Add Rechnerzentrale calculators to your website – for guides, blogs, associations, law firms or payroll offices. Free of charge, including commercial use.

Your benefits

  • No cookies, no tracking – nothing to add to your privacy policy.
  • Always up to date: new values at the turn of the year apply to your embed automatically.
  • Just an iframe: no third-party script on your site, optionally a tiny inline script for the right height.
  • Light, dark or automatic to match your visitors’ settings.
  • Presets possible: the current inputs can be included in the code.

How it works

  1. Pick a calculator from the list below and open it.
  2. Below the result, tap “Embed”, choose a theme and preset values if needed.
  3. Copy the code and paste it into your page – for example as an HTML block in WordPress.

Terms of use

  • Embedding is free of charge, including on commercial websites.
  • The calculator, the source line inside it and the link line below it stay unchanged and visible; the code must not be changed in a way that hides, shortens or removes the calculator or the links, or marks them “nofollow”.
  • Results are calculated carefully but without warranty; they are no substitute for tax or legal advice.
  • We may change calculators and discontinue individual embeds or the service as a whole.
  • Embedding on pages with unlawful content is not permitted.

Calculators in your own design

Would you like a calculator in your colours and font, without our source link, with your own presets or with additional fields? We can build it for you.
