## Formula

Cost = IT kW × PUE × hours × price.

- 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).

## Inputs

- 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 kW IT, PUE 1.5, 8,760 hours at $0.10.
1. 160 × 1.5 × 8,760 = 2,102,400 kWh.
2. × 0.10 = $210,240.

## 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.

## 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.
