+  The fixed premium fee is denominated in USD but no USD is ever used. The LINK equivalent of the fee is calculated at
+  request time, and then deducted from your subscription in LINK at response time. See the [example cost
+  calculation](/chainlink-functions/resources/billing#cost-calculation-example) for more information.
