How it works
- Copy the code under the calculator you want.
- Paste it into your page where the calculator should appear.
- Done — your visitors calculate without leaving your site.
Every CalcPrincipal calculator can live on your website or blog, free. Pick a calculator below, copy its code and paste it into your page's HTML: the calculator appears there, ready to use, and stays maintained and up to date on our side. The small credit line under it is the only thing we ask in return.
