Frequently Asked Questions

Common questions about FizzyTech HST Calculator

Nowhere until you place it. Use the shortcode, the block, a widget, or switch on automatic insertion or the floating button in Settings → HST Calculator → Placement.

Yes. Each one works independently, and each block can have its own colours.

Settings → HST Calculator → Tax rates, edit the number, save. There is also a "Restore built-in rates" button.

Yes. All the maths runs in the browser, so a cached page behaves exactly like an uncached one. I changed a setting and the page still looks the same. Saving settings clears your page cache automatically — WP Rocket, W3 Total Cache, WP Super Cache, LiteSpeed, WP Fastest Cache, SiteGround Optimizer, Cache Enabler, WP-Optimize, Breeze, Hummingbird, Comet Cache, Swift Performance, Autoptimize, Nginx Helper, Kinsta and Pagely are all handled. There is also a "Clear page cache" button next to Save. If a change still is not showing, the cache is one this plugin cannot reach: a server-level cache at your host, or a CDN such as Cloudflare. Clear it there. Also try a private browsing window, to rule out your own browser holding an old copy.

Only if you switch it on. It is off by default, nothing in the plugin depends on it, and when shown it is marked rel="nofollow" so it cannot affect your site's search ranking either way.

This version covers the five HST provinces, which use a single combined rate. You can add other provinces and rates by hand in the Tax rates tab, but the display will describe the amount as HST.
