This document explains Cloud Scheduler pricing details.
Cloud Scheduler pricing is based on the job. A Cloud Scheduler job defines a single activity scheduled to run at a frequency provided in the definition.
The actual running of a job is called an execution. A job is not billed for individual executions. For instance, if a single job is defined to run for "every day of the month", then that job is billed $0.1/month and not $3/month for 30 executions of that single job.
Each Google billing account gets 3 jobs per month free. Note that the free tier is measured at the account level not the project level. For example, if your account has 5 projects with 2 jobs each, you will have 3 free jobs and 7 paid jobs.
|Job cost||Free tier|
|$0.10 per job per month||3 free jobs per month, per billing account|
