Hi, @Douglas_William. Internally, the granularity of the “build minutes” calculations is by the second.
We bill by the minute. We calculate by the second. You can see more details of your team’s build minutes use here:
You can see there on March 2, there were six builds in the day. However, the total build minutes use for the day is only one minute.
For example, if you have two builds each which are 15 seconds long (for a total of 30 seconds), your total usage would be 1 minute (because the total is rounded up to the nearest minute).
Another example, two builds, one which is 2 minutes 30 seconds and one which is 2 minutes and 31 seconds.
This would be 5 minutes and 1 second total so that monthly usage (assuming only these two builds in the billing cycle) would be 6 minutes as the 5:01 is rounded up to the nearest minute.
So, iIf you have 60 builds that are all 2 seconds each, that is going to bill as 2 minutes and not 60 minutes.
