How we worked it out

  1. Energy per hour: 750 W ÷ 1,000 = 0.75 kWh
  2. Cost per hour: 0.75 kWh × $0.135 = $0.101
  3. Cost per day: × 4 hours = $0.405
  4. Month and year: × 30 days = $12.15, × 365 days = $147.83

About air compressor running costs

Air compressors cycle as pressure falls and rises. Motor size and workload make real consumption vary substantially.

Typical sizes: 750 W, 1,500 W, 2,000 W, 3,000 W.

How to spend less: Fix air leaks and choose a tank and compressor suited to the tool.

What this estimate assumes

  • The appliance draws its full stated wattage the whole time it is on. Real units with a thermostat cycle off and cost less.
  • Wattage is the typical label value, not a measured value. Check the label on your own appliance.
  • The rate is an approximate residential average in Oregon. Your bill may include fixed fees, tiers or time-of-use pricing. Edit the rate above.
  • A month is 30 days and a year is 365 days.
