Compressed-Air Saving Calculator
This ROI calculator estimates how much air-gauge flow could be avoided during idle time. It uses your measured flow, operating schedule, tariff and reduction assumption; it is not a compressor energy audit.

Worked example
Ten gauges at 25 L/min for 16 hours/day and 300 days/year consume an estimated 72,000 m³ annually. If half the time is idle and idle flow falls 90%, the avoidable volume is 32,400 m³.
Load the example in the calculatorFormula and methodology
- Annual volume is calculated from simultaneous gauge flow and scheduled operating time.
- Only the entered idle fraction and achievable reduction are counted as avoidable volume.
- Simple payback divides entered investment by annual monetary saving and excludes financing and maintenance effects.
Annual m³ = gauges × L/min × 60 × hours/day × days/year ÷ 1,000Saved m³ = annual m³ × idle fraction × reductionSaving = saved m³ ÷ 1,000 × cost per 1,000 m³ How to interpret the result
- The estimate is sensitive to simultaneous operation, leakage and the method used to calculate compressed-air cost.
- Verify flow and idle time at the machine before approving investment.
- An air-saving control must preserve measurement readiness, stability and safe restart behaviour.
Common errors and limitations
- Using compressor nameplate flow instead of measured point-of-use flow.
- Assuming every gauge operates simultaneously.
- Using electricity tariff alone instead of a validated compressed-air cost.

Frequently asked questions
What air cost should I enter?
Use your plant’s validated cost per 1,000 m³, including relevant power and operating costs. If unavailable, treat the result as a scenario only.
Does lower flow affect measurement?
It can. Air-saving controls should reduce flow only in defined idle states and restore a stable measurement condition before use.
Is leakage included?
Only if it is included in the measured gauge flow or separately reflected in your assumptions.
