Compressed air cost calculator
Estimate what compressed air inefficiency could be costing your organisation.
Enter a few details about your compressed air system to create an indicative estimate of annual energy cost, leakage cost and potential savings.
The result is an estimate based on your inputs and editable assumptions. It does not replace measured site data or a formal compressed air assessment.

Indicative estimate based on the values and assumptions entered
This estimate currently includes leakage reduction only.
- Estimated annual compressor electricity use
- 780,000 kWh
- Estimated annual energy cost
- €117,000
- Estimated annual leakage cost
- €23,400
- Potential annual leakage saving
- €14,040

Additional improvement may include opportunities related to pressure, control, operating practices or inappropriate use. Enter a value only if you have a reasonable basis for the estimate.
Based on the values entered, the system is estimated to use 780,000 kWh of electricity per year. At the selected electricity price, this represents approximately €117,000 in annual energy cost. With an estimated leakage level of 20%, the current leakage cost is approximately €23,400. Removing 60% of that leakage produces an indicative annual saving of approximately €14,040.

Calculation methodology
A transparent estimate based on energy, operating hours and leakage assumptions.
The calculator estimates annual compressor electricity use from installed power, average use and operating hours.
Annual energy use = Installed power × Utilisation × Operating hours
It then estimates annual energy cost using the entered electricity price.
Annual energy cost = Annual energy use × Electricity price
The leakage estimate is applied to the annual energy cost.
Annual leakage cost = Annual energy cost × Leakage percentage
Potential savings are calculated from the share of current leakage expected to be removed.
Potential leakage saving = Annual leakage cost × Expected leakage reduction
Any additional improvement estimate is included only when actively entered by the visitor.
Additional saving = Annual energy cost × Additional improvement percentage
Total potential saving combines leakage saving and any additional saving.
Total saving = Potential leakage saving + Additional saving
What this calculator does not include
- Compressor efficiency at different load points
- Pressure related energy effects
- Air demand profiles
- Load and unload losses
- Heat recovery
- Production interruptions
- Leak location and repair cost
- Pipe system pressure drop
- Air quality requirements
- Seasonal operating changes
- Equipment condition
- Local taxes and electricity tariff structures
A measured compressed air assessment may produce a materially different result.
From estimate to measured performance
The better the data, the more useful the decision.
Installed power and operating hours can create a useful first estimate. Measurement of actual electricity use, airflow, pressure and leakage provides a stronger basis for operational and investment decisions.
Use available system information to understand the possible scale.
Collect actual energy, flow, pressure and leakage data.
Assign ownership, report performance and act on priorities.
Independent knowledge without an equipment sales agenda.
The calculator and surrounding guidance are informed by LMS Nordic's wider field experience.
