About this calculator

Electricity is typically 70–80% of a compressor's total lifetime cost, far exceeding the purchase price. This calculator estimates the daily, monthly and annual electricity consumption and cost of running a compressor, based on its input power rating and duty cycle.

Formula

kWh/day = kW × Hours/day; Cost = kWh × Rate
  • kWCompressor input power — kilowatts
  • RateElectricity tariff — currency per kWh

Worked Example

Given: A 15 kW compressor runs 16 hours a day, 26 days a month, at ₹8/kWh.

Result: Daily: 15×16 = 240 kWh → ₹1,920. Monthly: 240×26 = 6,240 kWh → ₹49,920. Annual: ₹5,99,040.

How to Use

  1. Enter the compressor's electrical input power in kW (from the nameplate or motor power calculator, not just FAD).
  2. Enter typical running hours per day and working days per month.
  3. Enter your electricity rate per kWh.
  4. Click Calculate for daily, monthly and annual consumption and cost.

Important Assumptions

  • Assumes the compressor runs at full rated power for the entire stated hours — real compressors cycle between load and unload (or vary with a VSD), so actual consumption is often lower than this full-load estimate.
  • Use average measured power for the most accurate result if available.

Common Mistakes

  • Using FAD (m³/min) instead of the compressor's input power (kW) in this calculator.
  • Ignoring load/unload cycling, which typically means actual average power is below the full-load nameplate rating.

Frequently Asked Questions

Why is electricity the biggest cost of owning a compressor?

Over a typical 10-year life, electricity commonly accounts for 70–80% of total cost of ownership, with purchase price and maintenance making up the rest — this is why compressor efficiency and leak control matter economically.

How can I reduce this cost without buying new equipment?

Fixing air leaks, reducing unnecessary pressure, and avoiding excessive unloaded running time are the most common low-cost ways to cut compressed air electricity cost.
