What this calculator tells you
Enter your compressor's horsepower, load, and run hours to see what it costs in electricity per month, per year, and over 10 years.
Your Compressor
Results
Annual electricity use: 0 kWh
Annual electricity cost:
$0 per year
Cost per month: $0
10-year energy cost: $0
Over 10 years, electricity is typically 75% of a compressor's total cost of ownership. The purchase price is about 12%.
How this is calculated
- Shaft power draw = HP x 0.746 kW per HP / motor efficiency %.
- Annual kWh = power draw x average load % x operating hours per year.
- Annual cost = annual kWh x electric rate ($/kWh).
- Monthly cost = annual cost / 12. The 10-year figure is annual cost x 10 at today's rate, with no escalation.

Common questions
How much electricity does an air compressor use per year?
Annual kWh is roughly compressor horsepower times 0.746 kW per HP, divided by motor efficiency, times average load percentage, times operating hours. A 50 HP compressor at 75 percent load and 93 percent motor efficiency running 4,160 hours per year uses about 125,000 kWh, which is roughly 15,000 dollars per year at 12 cents per kWh.
What share of a compressor's total cost of ownership is electricity?
Over a 10 year life, electricity is typically about 75 percent of a compressor's total cost of ownership. The purchase price is only about 12 percent, with maintenance making up most of the rest. That is why efficiency, proper sizing, and leak control matter far more than sticker price.
How can I reduce my air compressor's energy cost?
The biggest wins are fixing leaks, lowering system pressure to the minimum your processes need, matching compressor size to real demand, and using a variable-speed drive when demand swings. An air system audit identifies which of these applies to your plant and what each is worth per year.
