Data Center Energy Cost Calculator
Data Center Energy Cost: Cost = IT kW × PUE × hours × price. Methodology stated, your own inputs only.
In short
Data Center Energy Cost: Cost = IT kW × PUE × hours × price. Methodology stated, your own inputs only.
Formula: Cost = IT kW × PUE × hours × price.
What this calculator does
Data Center Energy Cost: Cost = IT kW × PUE × hours × price. Methodology stated, your own inputs only. Worked example, questions and limitations included.
Use it to turn Currency (symbol only, never converted), Average IT load, Your measured PUE, Hours in the period, and the other shown inputs into a checked result you can compare, copy, or rerun with different assumptions.
The page shows the formula, a numeric worked example, and the assumptions that affect this data centers calculation.
Inputs and what they mean
- Currency (symbol only, never converted)
- — choice value.
- Average IT load
- — number value.
- Your measured PUE
- — number value.
- Hours in the period
- — number value.
- Your energy price per kWh (from your bill or a saved rate)
- — number value.
How to use it
- Enter each value in the unit shown next to the box (use the unit converter first if your numbers are in other units).
- Check the breakdown to see every intermediate step.
- Read the limitations before relying on the result.
Formula
Methodology: facility energy = IT energy × PUE (The Green Grid), priced at your tariff.
No PUE or electricity price is assumed.
Demand charges are not included — use the Electricity Cost calculator for a full bill.
Cost = IT kW × PUE × hours × price.
Inputs used: Currency (symbol only, never converted), Average IT load, Your measured PUE, Hours in the period, Your energy price per kWh (from your bill or a saved rate).
Worked example
A year
- 160 × 1.5 × 8,760 = 2,102,400 kWh.
- × 0.10 = $210,240.
Reading the result
The headline figure is the main answer. Any breakdown underneath shows the parts that make it up, so you can check the working and see what changes when you adjust an input.
Saved energy rates
No reference rates are saved yet. Enter the price per kWh from your own bill — this site never assumes one.
Limitations and assumptions
- Flat price; no demand or time-of-use charges.
- Constant IT load and PUE.
- Results are estimates built only from the figures you enter. No electricity, fuel or gas price, equipment efficiency or benchmark is built in — tariffs vary by supplier, region and time, and equipment data must come from the manufacturer. Designs and installations must be checked by a qualified professional.
- The result depends on the values you enter for this data center energy cost calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.

Common questions
Why isn't an electricity or fuel price filled in?
Prices differ by country, supplier, tariff and time of use, so there is no universal figure. Enter the rate from your bill or contract, or pick a dated saved rate if one is listed on the page.
Is there a target or industry average built in?
No. Results depend on climate, design, load and measurement point, so none is shown. Compare against your own history.
Why split IT and overhead?
It shows how much of the bill goes to cooling and losses rather than computing. Check the formula, example, and limitations on this page before using the result for a real data centers decision.
How do I use the Data Center Energy Cost Calculator?
Enter the required values for Currency (symbol only, never converted), Average IT load, Your measured PUE, Hours in the period, Your energy price per kWh (from your bill or a saved rate). The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.
What formula does the Data Center Energy Cost Calculator use?
Cost = IT kW × PUE × hours × price. The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone.
Can the Data Center Energy Cost Calculator be used for exact decisions?
Use it as a calculation aid, not as a substitute for checking the underlying rule, contract, policy, or professional advice that applies to your situation. When a result depends on local rules, personal details, prices, or dates, enter those values yourself and confirm them before acting.
