How build minutes/seconds are calculated in Bitbucket Cloud?

Summary

If there are two pipelines and each takes 10 seconds, it will be counted as 20 seconds only. However, there are a few exceptions, in which build seconds are calculated more.  

Solution

Consider a pipeline built with two parallel steps, each taking 1 minute to run.

In this scenario:

• Build duration: 1 minute

• Build minutes used: 2 minutes (since the parallel steps run simultaneously, the individual build minutes are accounted for separately)

Consider a pipeline build that runs with 2x memory configuration and completes in 1 minute.

In this case:

• Build duration: 1 minute

• Build minutes used: 2 minutes (because the 2x memory usage entails 2x build minutes to be accounted for billing purposes)

Consider a pipeline build that runs with 4x / 8x memory configuration and completes in 1 minute.

In this case:

• Build duration: 1 minute

• Build minutes used:

  • 4 minutes (because the 4x memory usage entails 4x build minutes to be accounted for billing purposes)

  • 8 minutes (because the 8x memory usage entails 8x build minutes to be accounted for billing purposes)
