Power Cost Analysis Calculator

Calculate annual power costs, cost per rack, and potential savings from PUE efficiency improvements.

Total IT equipment power draw across all racks.
kW
Total active racks for per-rack cost allocation.
Current Power Usage Effectiveness. Industry average ~1.58.
Projected PUE after efficiency upgrades. Best-in-class: 1.1-1.2. Enter same as current if no improvement.
Blended electricity rate. US commercial avg ~$0.08-$0.12/kWh.
$/kWh

Current Costs

Total Facility Power:
IT Load x PUE.
-kW
Annual Energy Consumption:
Total facility power x 8,760 hours/year.
-MWh
Annual Power Cost:
Total annual electricity expense.
-
Monthly Power Cost:-
Cost per Rack per Month:
Monthly cost allocated equally across all racks.
-
Effective Rate (incl. overhead):
Utility rate x PUE = true cost per kWh delivered to IT.
-$/kWh

PUE Improvement Savings

Annual Cost at Target PUE:-
Annual Savings:-
Monthly Savings:-
Power Reduction:-kW
5-Year Savings:-
Reference: Uptime Institute Global Data Center Survey. US DOE estimates PUE improvement from 1.8 to 1.4 saves ~22% of energy. 8,760 hours/year.
