## Formula

Cost = full-load input kW × average load × hours × price.

- Methodology: energy cost of compressed air generation as set out in the U.S. DOE compressed air sourcebook.
- Unloaded running still draws power — use measured average load where possible.
- No price or load profile is assumed.
- Cost = full-load input kW × average load × hours × price.
- Inputs used: Currency (symbol only, never converted), Compressor electrical input at full load (data sheet), Average load in the period, Running hours, Your energy price per kWh (from your bill or a saved rate).

## Inputs

- Currency (symbol only, never converted)
- Compressor electrical input at full load (data sheet)
- Average load in the period
- Running hours
- Your energy price per kWh (from your bill or a saved rate)

## Worked example: A plant compressor

75 kW input, 70% average load, 6,000 h at $0.11.
1. 75 × 0.70 × 6,000 = 315,000 kWh.
2. 315,000 × 0.11 = $34,650.

## 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.

### What load should I use?

The average measured input as a share of full-load input. Unloaded compressors often still draw a large share.

### Is maintenance included?

No — energy only. Add maintenance separately.

### How do I get cost per volume of air?

Use the Compressed Air Cost calculator with the compressor's specific power. Check the formula, example, and limitations on this page before using the result for a real energy decision.

### How do I use the Compressor Cost Calculator?

Enter the required values for Currency (symbol only, never converted), Compressor electrical input at full load (data sheet), Average load in the period, Running hours, 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 Compressor Cost Calculator use?

Cost = full-load input kW × average load × 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.

## Limitations and assumptions

- Average load hides cycling losses.
- Energy only — no maintenance or capital.
- 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 compressor cost calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
