Abrasive Blasting, Shot Peening & Surface Prep calculator
Blast Compressor Energy Cost Calculator
Compressed air is one of the largest hidden costs in abrasive blasting. This calculator converts compressor energy use into dollars so shops can compare nozzle sizes, pressure settings, compressor packages, and blast schedules with energy included.
What this calculator does
- Estimate electrical energy cost from compressor kWh, utility rate, loaded duty percentage, and demand or fixed charges.
- you need to include compressor electricity in a blast quote or compare energy impact between setups
- Returns the compressor energy dollars associated with the blast job or time window.
Formula used
- Loaded energy cost = compressor energy × utility energy rate × loaded blast duty
- Total compressor energy cost = loaded energy cost + demand/fixed charge
Inputs explained
- Compressor energy: undefined
- Utility energy rate: undefined
- Loaded blast duty: undefined
- Demand/fixed energy charge: undefined
How to use the result
- Use it for quoting, energy projects, compressor comparisons, and pressure-reduction savings checks.
- Demand charges, diesel rentals, leaks, unloaded running, and heat recovery are only included if you add them in the fixed charge or energy input.
Common questions
- How do I estimate compressor kWh? Use metered energy when available, or compressor kW multiplied by loaded operating hours.
- Should unloaded compressor time count? Yes, include it in kWh if the compressor runs unloaded during the job.
- Can this compare nozzle sizes? Yes. Larger or worn nozzles raise CFM and compressor load, which should show up as more kWh or a higher duty percentage.
- Does this include abrasive cost? No. Use the blast media consumption and cost per square foot calculators for material and total prep cost.
