In one line

Every second a build, sandbox, or fleet instance stays alive becomes a line item.

What gets missed

Reserved capacity fleets bill from provisioning, not from when a build starts, with a 60-minute minimum per instance. Free-tier minutes cover on-demand small compute only, never fleets or sandboxes.
