Pump electricity cost
Price measured pump electrical demand and running hours.
Your inputs
Complete the fields for your selected method. Zero means intentionally zero, not unknown. Currency selection labels amounts; it does not convert exchange rates.
How this calculation works
measured input kW*hours*tariff. Metered alternative: pump cost = period metered kWh × matching price.
Use measured real electrical input kW, not volts × amps or shaft power. Hours describe time at that measured input. All rates are user supplied; no tariff lookup. An integrated kWh reading must not have duty cycle applied again. This does not select a pump or estimate hydraulic suitability.
What information do I need?
Use records for the same job, equipment or accounting period. Only the fields for your selected entry method are required. An unknown amount is not zero.
Input definitions and where to find them
- How do you know the energy use?: Choose the information you actually have. Only the selected method is required.
- Measured pump real electrical input (kW): Measured REAL pump electrical input at this operating point. Used with: Measured input power and operating schedule.
- Period running time (hours): Run-hour meter/controller log for the selected period. Used with: Measured input power and operating schedule.
- Electricity price per kWh (selected currency): Matching energy/volumetric tariff or bill component for electricity price per kwh, excluding fixed charges or other charges not modeled.
- Pump electricity for this chosen period (kWh): Use an isolated record or clearly labeled estimate matching this field and period. Do not substitute an unrelated whole-site total. Used with: Metered or separately estimated kWh.
Use the Where to find this value controls beside the inputs for available work-it-out helpers. Estimates remain your assumptions; a helper does not verify the source figures.
Worked example
Example amounts use US dollars (USD).
Example answer: Period electricity cost is $450.00 for the illustrative inputs below.
Example inputs
- How do you know the energy use?: Measured input power and operating schedule
- Measured pump real electrical input: 3.00 kW
- Period running time: 1,000.00 hours
- Electricity price per kWh: $0.15
- Period electricity cost
- $450.00
- Period electricity
- 3,000.00 kWh
These illustrative values are not recommended rates or industry averages. Replace every example input with your own figures.
Use the result well
Price measured pump electrical demand and running hours.
Keep inputs on the same scope and time basis. Calculations retain precision internally; displayed values generally round to two decimal places, with extra precision for very small values and whole-unit rounding where required. Economic comparisons describe your supplied assumptions and do not guarantee future results.
