Pump Electricity Cost Calculator

Use this calculator to estimate a water pump's electrical energy use and running cost. The tool works from motor output, estimated efficiency, power factor, operating time and your local electricity tariff.

Use the correct inputs

Read motor HP or kW from the nameplate. Efficiency converts motor output into estimated electrical input kW; runtime and the per-kWh tariff determine this tool’s energy-cost estimate. Power factor, supply phase and voltage are used separately for the optional current and kVA estimate; power factor does not directly multiply this calculator’s kWh cost. Use verified inputs.

Understand the result

The output is an estimate of energy consumption and cost for the period shown. Actual bills can differ because load, voltage, pump condition, flow restriction, starts, tariff slabs, demand charges and other site loads vary. Do not treat the result as a guaranteed bill amount.

Use it for comparison

Keep the same duty and water requirement when comparing two options. If measured current or power differs greatly from the estimate, ask a qualified electrician or pump technician to inspect the installation before changing protection settings or equipment.

Energy • Runtime • Cost

Estimate what your water pump costs to run.

Enter motor output power and efficiency to estimate energy use and running cost. Add verified electrical details when you also need an estimated current and kVA.
