Air Compressor (1.50 HP) Energy Calculator (Cost and kWh Usage)

Air compressors are a common appliance used in many industries and households. These machines are used for numerous purposes, from inflating tires to powering pneumatic tools. While air compressors are handy, they also consume a considerable amount of energy. In this article, we will explore the energy consumption and costs of using an air compressor with 1.50 horsepower.


How To Use This Calculator

Using this energy calculator is a simple and will help you determine the costs of running your appliance. Click on ‘Calculate’ to use the predefined values, or enter your daily usage in hours, appliance watts, and your current energy costs in dollars. The calculator will provide you with the daily, monthly, and yearly results. It’s important to ensure the accuracy of the information entered to get the most accurate results.

Hours Used Per Day

Enter the number of hours you estimate the appliance will be on throughout the day. To use fractions of an hour please use a decimal point in the form.

For example: 1 hour and 30 mintes would be 1.5, and 3 hours and 15 minutes would be 3.25

Power Used in Watts

The calculator already includes a default average wattage. If your appliance uses a different wattage then enter it in the calculator.

Your Energy Rate in kWh

The calculator includes an average energy rate (price in $/kWh) to use for the calculation. This may not be the exact price that you’re currently paying for electricity. If you know your energy rate please enter your price per kilowatt-hour.

Energy Consumption

The energy consumption of an air compressor depends on its horsepower, and in the case of a 1.50 HP appliance, it uses 2200 watts. The wattage indicates the amount of power the air compressor draws from the electrical supply.

To understand the energy consumption of this appliance, let’s assume that it runs for two hours daily. Using the formula below, we can calculate the daily energy consumption.

Daily Energy Consumption = Wattage x Hours of use = 2200 watts x 2 hours = 4400 watt-hours

Based on this calculation, we can determine that the air compressor consumes 4.4 kWh of energy daily.

The cost of energy is continually increasing, and it is essential to make informed decisions about the appliances we use. This applies to air compressors, which consume a considerable amount of energy. Understanding the energy consumption of these devices helps users make informed decisions about their usage and costs. By managing usage and employing energy-saving techniques, users can reduce their energy bills while still enjoying the benefits of an air compressor.

Cost in Dollars of Energy Usage

With the daily energy consumption of 4.4 kWh, we can calculate the daily, monthly, and yearly energy costs using the formula below.

Daily Energy Cost = Daily Energy Consumption x Energy price per kWh = 4.4 kWh x $0.12/kWh = $0.53/day

Monthly Energy Cost = Daily Energy Cost x Number of days in a month = $0.53 x 30 = $15.84

Yearly Energy Cost = Daily Energy Cost x Number of days in a year = $0.53 x 365 = $192.72

Based on these calculations, we can determine that an air compressor with 1.50 horsepower costs approximately $192.72 per year to operate.

Money Saving Tips

  1. Check for leaks: Air compressors are prone to leaks, which can cause a drop in pressure, resulting in more energy consumption. Regularly inspecting hoses, fittings, and other parts for leakages can help reduce energy consumption and save money.

  2. Use the right tool for the job: Using a smaller air compressor for smaller jobs can help save energy and reduce costs.
  3. Turn off the compressor: Turning off the compressor when it is not in use can significantly reduce energy consumption.
  4. Use an energy-efficient compressor: When looking to purchase an air compressor, consider selecting an energy-efficient model. These models are designed to consume less energy and reduce energy bills.

By implementing these energy-saving techniques, users can reduce their energy costs and operate their air compressors more efficiently.


Air compressors with 1.50 horsepower are essential appliances, but they consume a considerable amount of energy. Understanding the energy consumption of these devices and employing energy-saving techniques can significantly reduce energy bills. By adopting these measures, users can operate their air compressors efficiently while saving money.
