Compressed Air Cost Calculator
Compressed Air Cost: kW = specific power × flow. Methodology stated, your own inputs only.
In short
Compressed Air Cost: kW = specific power × flow. Methodology stated, your own inputs only.
Formula: kW = specific power × flow. Cost = kW × hours × price. Cost per m³ = specific power ÷ 60 × price.
What this calculator does
Compressed Air Cost: kW = specific power × flow. Methodology stated, your own inputs only. Worked example, questions and limitations included.
Use it to turn Currency (symbol only, never converted), Specific power (manufacturer data sheet), Average air delivered, 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 energy calculation.
Inputs and what they mean
- Currency (symbol only, never converted)
- — choice value.
- Specific power (manufacturer data sheet)
- — number value.
- Average air delivered
- — 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: cost of compressed air from specific power, the approach in the U.S. DOE compressed air sourcebook.
Specific power comes from the compressor's data sheet (e.g. CAGI sheet) at your pressure.
Leaks and artificial demand count as delivered air.
kW = specific power × flow. Cost = kW × hours × price. Cost per m³ = specific power ÷ 60 × price.
Inputs used: Currency (symbol only, never converted), Specific power (manufacturer data sheet), Average air delivered, Hours in the period, Your energy price per kWh (from your bill or a saved rate).
Worked example
A year of air
- 6.5 × 10 = 65 kW.
- 65 × 4,000 = 260,000 kWh.
- × 0.12 = $31,200.
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
- Specific power varies with pressure and part load.
- Dryers and auxiliary loads are not included unless in specific power.
- 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 compressed air 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.
Where does specific power come from?
The manufacturer's performance data sheet at your operating pressure. It is equipment-specific, so none is assumed.
Free air or compressed volume?
Use the same basis as the data sheet, usually free air delivered (FAD). Check the formula, example, and limitations on this page before using the result for a real energy decision.
Does this cover leaks?
Leaked air is delivered air, so it is included in cost if it is in your flow figure. Check the formula, example, and limitations on this page before using the result for a real energy decision.
How do I use the Compressed Air Cost Calculator?
Enter the required values for Currency (symbol only, never converted), Specific power (manufacturer data sheet), Average air delivered, 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 Compressed Air Cost Calculator use?
kW = specific power × flow. Cost = kW × hours × price. Cost per m³ = specific power ÷ 60 × 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.
