About this calculator

This calculator is aimed at industrial cost planning and budgeting — it projects a compressor's full-year electricity running cost directly from input power and duty cycle, for comparing options, justifying efficiency upgrades, or building an annual utility budget.

Formula

Annual Cost = kW × Hours/day × Working Days/yr × Rate

kWCompressor input power — kilowatts
RateElectricity tariff — currency per kWh

Worked Example

Given: A 15 kW compressor runs 16 hrs/day, 310 days/year, at ₹8/kWh.

Result: Annual cost = 15 × 16 × 310 × 8 = ₹5,95,200.

How to Use

Enter the compressor's electrical input power (from the nameplate or the Motor Power / Compressor Power calculator).
Enter running hours per day and total working days per year.
Enter your electricity rate.
Click Calculate for the projected annual running cost.

Important Assumptions

Assumes constant full-load operation for the stated hours; real compressors cycle load/unload, so actual annual cost is often somewhat lower than this full-load estimate unless using average measured power.

Common Mistakes

Using nameplate motor HP directly instead of actual electrical input power in kW.

Frequently Asked Questions

How does this differ from the Compressor Electricity Cost Calculator?

The calculation is the same; this version is framed around annual budgeting and cost comparison for industrial planning, while the other breaks the figure down by day and month as well.

These calculators are provided for informational and estimation purposes. Results depend on the assumptions and input values used. Always verify critical engineering calculations against applicable standards, manufacturer specifications, site measurements, and qualified professional advice.
