Add a VAT calculator widget to your page or post.
Add a VAT calculator to your WordPress site, using the VAT Calculator Plus web site widget. You can set a fixed VAT rate or let your visitor set the rate. The VAT calculator has a clean, modern look, and if you are a CSS guru, you can style it totally yourself.
Use the VAT Calculator Plus Settings page to generate a ShortCode that you can copy and paste into your content.
