Advocate IBillin an Event steram based on cu consumption
Hi KGU_16031986
Thank you for contacting the Microsoft Fabric Community Forum.Your calculation is correct, with just a minor adjustment to consider:
The conversion from CU-seconds to CU-hours and the application of the per-CU-hour rate are accurate. The total cost over 14 days is approximately AUD 32.9.
The only suggestion is to normalize by the full 14-day window rather than the “active duration” (13.09 days), since the CU-consumption metric already reflects active versus idle usage.
Per calendar day: 172.38 CU-h ÷ 14 = 12.31 CU-h/day
Daily cost: AUD 2.35/day
Estimated 30-day cost: ≈ AUD 70.4
If you prefer to use “active days” (13.09), your figures of AUD 2.51/day and AUD 75.3/month remain valid.
In summary, the total cost for the 14-day period (AUD 32.9) is correct. The difference in monthly projections depends on whether you use calendar days or active usage days for normalization.

Community ChampionI would perhaps multiply by 1.25.
Because, your capacity is likely not running at 100% on average - that would be risky due to throttling. Let's say your target average utilization of the capacity is 80%, so you have a safety buffer of 20% to avoid entering throttling.
In that case, I'd multiply the chargeback by 1.25 (100%/80%) so that everyone's contributing to paying for the safety buffer as well.
