Air Compressor Power Costs

The yearly cost of operating an air compressor can be approximated as:

C = P_bhp 0.746 c_kWh h_year / μ

or

USD Cost per Year = (Horse Power x 0.746 x Cost per kWh x Operating Hours per Year) / Motor Efficiency

All cost units should be in USD. Air compressor power costs count for typically 60-70% of total operating costs. Fixed costs are typically from 10-20% and other operating costs are typically 15-25% of the total operating costs.
