Data Centre Power & PUE Calculator.
Calculate facility power, yearly energy, electricity cost, CO₂ emissions and cooling load from IT load and PUE.
About 1.1–1.2 for efficient hyperscale sites, 1.4–1.8 for typical facilities, 2+ for small server rooms.
Use your country’s or supplier’s published factor.
- Facility power
- 75 kW
- Overhead (cooling, UPS losses, lighting)
- 25 kW
- DCiE (1 ÷ PUE)
- 66.7 %
- Cost per month
- 8,218 USD
- Cost of the overhead per year
- 32,873 USD
- Emissions per year
- 263 t CO₂
- Heat from IT equipment
- 170,600 BTU/h · 14.2 tons
- Uses the average IT load over a year (8,766 hours). Peak load sizes cooling and power distribution; average load drives the bill.
- PUE is defined by ISO/IEC 30134-2 and The Green Grid.
How to use Data Centre Power & PUE Calculator
Enter the average IT load, PUE, your electricity price and currency, and your grid emission factor.
How it works
Facility power = IT load × PUE; energy = facility power × 8,766 hours; cost and CO₂ multiply energy by price and emission factor; heat = IT watts × 3.412 BTU/h.
Example
50 kW of IT at PUE 1.5 draws 75 kW, 657.5 MWh a year: about 98,600 USD at 0.15 per kWh.
