-    Estimated Billed Capacity units indicates the number of capacity units using which the billing is estimated. This is calculated as the greater value between Current capacity units (capacity units required to load balance the traffic) and Fixed billable capacity units (minimum capacity units kept provisioned).
+    The **Estimated Billed Capacity units** metric indicates the number of capacity units estimated for billing. This metric is calculated as the greater value between **Current capacity units** (capacity units required to load balance the traffic) and **Fixed billable capacity units** (minimum capacity units kept provisioned).
 
 More metrics such as throughput, current connections and compute units are also available to understand bottlenecks and estimate the number of capacity units required. Detailed information is available at [Application Gateway Metrics](application-gateway-metrics.md)
