#### How pipeline quota usage is calculated
Pipeline quota usage is calculated as the sum of the duration of each individual job. This is slightly different to how pipeline _duration_ is [calculated](#how-pipeline-duration-is-calculated). Pipeline quota usage doesn't consider any overlap of jobs running in parallel.
For example, a pipeline consists of the following jobs:
- Job A takes 3 minutes.
- Job B takes 3 minutes.
- Job C takes 2 minutes.
The pipeline quota usage is the sum of each job's duration. In this example, 8 runner minutes would be used, calculated as: 3 + 3 + 2.
