Leak economics
See what wasted compressed air could be costing your operation over a year.
Estimated annual energy cost
$1,057
At these settings, the leaks represent about 2.1 kW of compressor input.
Formula: leak CFM × 0.18 kW/CFM × (pressure ÷ 100) ÷ efficiency × hours/week × 52 × electricity rate. The 0.18 kW/CFM factor is a planning benchmark at 100 psig. A leak count uses a rough 0.25 CFM per leak.
Operating cost
See what it costs to produce each thousand cubic feet of compressed air.
Cost per 1,000 cubic feet
$0.33 / MCF
Annual electricity cost
$41,381
Annual air produced
124,800,000 ft³
$/MCF is the cost of producing one thousand cubic feet of compressed air, useful for comparing systems and spotting the cost of leaks and inefficiencies.
Formula: kW input = hp × 0.746 ÷ (efficiency/100); annual kWh = kW input × hours per week × 52; annual air produced (ft³) = CFM × 60 × hours per week × 52; cost per MCF = (annual kWh × $/kWh) ÷ (annual air produced ÷ 1000). Assumes steady delivered output, operating schedule, and electricity rate; results are planning estimates.
Project planning
Estimate the utility incentive available before you commit capital or apply for a program.
Total estimated incentive
$10,000
Demand incentive (kW × $1,800)
$18,000
Energy incentive (kWh × $0.20)
$10,000
Applies: Demand incentive — the greater of the two. The 50% project-cost cap limits the estimate.
50% project-cost cap: $10,000
Net cost after incentive
$10,000
Covers 50% of project cost
Enter a project cost to apply the 50% cap.
Utilities pay for either the peak demand a project removes or the energy it saves, whichever pays more, and never more than half the project cost. A completed air audit is what pins down the real numbers.
Formula: the incentive is the greater of the demand incentive ($1,800 per kW saved) or the energy incentive ($0.20 per kWh saved) — the two do not combine — and the result is capped at 50% of project cost. Actual program rates, caps, and eligibility vary by utility and region.

Prefer to work offline? We’re building a small library of practical spreadsheet tools for plant and maintenance teams.
These are the same SteddyAir workbooks used in the field — free to download.
Excel spreadsheet (.xlsx) · XLSX
A multi-tab workbook with seven handy tools in one file: motor amp draw and in-rush current, SCFM ↔ ACFM conversion, diesel vs electric running cost, pump-up and reverse pump-up compressor capacity tests, refrigerated dryer sizing, and a compressor oil carryover estimator.
Excel spreadsheet (.xlsx) · XLSX
Work out the compressed air — and the money — lost through timed condensate drains. Enter drain size, pressure and open/close cycle for up to 20 drains and see the annual energy cost, plus typical system efficiency benchmarks.
Excel spreadsheet (.xlsx) · XLSX
Finds your system's leakage rate from a simple load/unload test and turns it into an annual energy cost, using your tank and piping volume, compressor ratings and hydro rate. Includes a second tab for a quick leak-plus-storage estimate.
Excel spreadsheet (.xlsx) · XLSX
Checks whether your air velocity and pressure drop are within recommended ranges for headers, branch lines, drops and tools, and recommends the minimum pipe size to fix it. Includes pipe sizing and fitting equivalent-length reference tabs.
Excel spreadsheet (.xlsx) · XLSX
Estimates how much water your aftercooler and dryer remove, based on flow, pressure, inlet temperature, humidity, approach temperature and target pressure dewpoint — with typical dryer dewpoint reference data.
