+Browser Rendering requires a Workers plan. Learn more about [Workers plans](/workers/platform/pricing/).
+
 There are two ways to use Browser Rendering. Depending on the method you use, here is how billing works:
-- [**REST API**](/browser-rendering/rest-api/): Charged for **Duration** only ($/browser hour)
-- [**Workers Bindings**](/browser-rendering/workers-bindings/): Charged for both **Duration** and **Concurrency** ($/browser hour and # of concurrent browsers)
+- [**REST API**](/browser-rendering/rest-api/): Charged for **browser hours** only
+- [**Workers Bindings**](/browser-rendering/workers-bindings/): Charged for both **browser hours** and **concurrent browsers**
+
+Browser hours are shared across both methods (REST API and Workers Bindings).

 ###  Do failed API calls, such as those that time out, add to billable browser hours?
 No. If a request to the Browser Rendering REST API fails with a `waitForTimeout` error, the browser session is not charged.
