ELECTRICITY COST$22.50

Custom at 1.000 kW × 1 × 5.0000 h/day × 30 days = 150.000 kWh; at $0.1500/kWh

Estimate based on the values shown
MethodEnergy = power in kW × quantity × hours/day × days; cost = energy × utility price. Presets provide typical rated power and can be replaced with a custom W or kW value. Power accepts W, kW, BTU/h, metric horsepower, or refrigeration tons; schedules accept daily minutes/hours and weekly, monthly, or annual hours.

Before you use the result

Check the entered units and assumptions before using the result for purchasing, construction, engineering, or safety decisions.

How to use the Electricity Cost Calculator

Estimate electricity cost from appliance preset, power, power unit with the Electricity Cost Calculator. It includes Appliance electricity cost, Appliance energy use, Runtime from energy workflows, so choose the one that matches the values you actually know. Use it to check a practical estimate, paying close attention to the selected units and assumptions.

Step by step

  1. For the Electricity Cost, enter appliance preset, power, power unit, quantity, usage amount. Keep each value in the unit displayed beside its field.
  2. Review the selected Electricity Cost workflow and inputs, then read electricity cost in the result panel.
  3. Change one Electricity Cost assumption at a time to compare scenarios. Use Reset to restore this tool's worked example values.

How the calculation works

Energy = power in kW × quantity × hours/day × days; cost = energy × utility price. Presets provide typical rated power and can be replaced with a custom W or kW value. Power accepts W, kW, BTU/h, metric horsepower, or refrigeration tons; schedules accept daily minutes/hours and weekly, monthly, or annual hours.

Worked example

In the Electricity Cost worked example, appliance preset Custom, power 1,000, power unit W, quantity 1 produces electricity cost of $22.50. Custom at 1.000 kW × 1 × 5.0000 h/day × 30 days = 150.000 kWh. Review the displayed units before comparing the result.

Understanding the result

The Electricity Cost reports electricity cost. Use it to check a practical estimate, paying close attention to the selected units and assumptions. Check the entered units and assumptions before using the result for purchasing, construction, engineering, or safety decisions.

How to check the answer

Check the Electricity Cost result by reversing the conversion or recomputing electricity cost from appliance preset, power, power unit. For construction, electrical, weather, or purchasing decisions, compare the result with the applicable specification or professional guidance.

Common questions

What does the Electricity Cost calculate?

Estimate electricity cost from appliance preset, power, power unit with the Electricity Cost Calculator.

Which Electricity Cost inputs have the biggest effect?

electricity cost responds directly to appliance preset, power, power unit, quantity, usage amount. Change one input while holding the others constant to see its effect.

Is the Electricity Cost result exact?

Check the entered units and assumptions before using the result for purchasing, construction, engineering, or safety decisions. Recheck appliance preset, power, power unit and use electricity cost only for a decision where that level of precision is appropriate.
