# Kafka Streams Billing Confluent bills Kafka Streams per hour for each Apache Kafka® cluster that has a connected Kafka Streams application. The charge scales with the number of eCKU on the cluster, or with the CKU count on a Dedicated cluster. The charge applies per cluster, not per application or client. For current prices, see the [Confluent Cloud pricing page](https://www.confluent.io/pricing/). ## Related content - [Kafka Streams overview](../../kafka-streams/overview.md#client-kafka-streams) - [FAQ for Confluent Cloud Billing](../billing-faq.md#billing-faq)
