@Robin De Greve Thanks for reaching out. Container Apps jobs, resources consumed by each execution are billed at the active rate from start to completion. No usage charges apply when a job is not running executions. This suggests that idle usage pricing, which applies to Container Apps revisions and replicas, does not apply to Container App jobs.
do let me know incase of further queries, I would be happy to assist you.
