FOCUS column
ChargePeriodEnd
The exclusive end of the charge period. Some exports do not state it, in which case the value is absent rather than assumed, because only the granularity of the source knows where a charge period ends and a guessed end would misplace usage that spans a boundary.
Example
The same hourly charge carries 2026-09-12T15:00:00Z; a daily Azure Cost Details row leaves it empty because the export gives only a date.
Where it comes from, per export
The export column that feeds ChargePeriodEnd in each format the platform ingests, and the transform applied. A format with no row does not carry the column; the value is then absent rather than guessed.
| Export | Source column | Transform |
|---|---|---|
| AWS Data Exports, FOCUS | ChargePeriodEnd | as is |
| Azure Cost Management, FOCUS export | ChargePeriodEnd | as is |
| Azure Cost Details (actual cost) | Not carried | — |
| Azure Cost Details (amortized cost) | Not carried | — |
| Google Cloud detailed billing export | usage_end_time | cast to datetime |
How Runcost uses it
Runcost keeps the value nullable on purpose and infers the granularity per export, so a missing end never reads as the epoch.
