In one line
Per node-hour for every node in the cluster, whether or not anything is hitting the cache.
What gets missed
DAX bills nodes, not cached reads, and a production cluster wants three nodes across AZs. The cluster keeps billing after traffic stops, and the DynamoDB reads it saves you are a separate, smaller line.
