Electricity Cost Calculator
Calculate electricity use from measured kWh or input power, operating hours, equipment count and average load. Apply a monthly state/sector average or enter your actual rate. No local tariff, demand-charge schedule or tax rule is inferred.
Your consumption and costs
Choose one consistent reporting period. Use a decimal point and optional comma thousands (1,234.56). Zero means intentionally zero.
Results
Enter your figures and calculate.
How this calculation works
kWh = measured electricity OR input kW × operating hours × machine count × average load%; energy cost = kWh × USD/kWh.
Worked example
Illustrative figures, not current rates. Use Load illustrative example to inspect every input.
- Calculated consumption in the chosen period
- 100 kWh
- Energy or fuel cost at entered price
- 16 USD
- Cost at comparison price
- 20 USD
- Change caused by comparison price
- 4 USD
- Total period cost including entered other costs
- 16 USD
Use the results responsibly
- All figures refer to one user-chosen period. These are energy-cost scenarios, not complete utility bills or supplier offers.
- Electricity/natural-gas reference averages are monthly and published with a lag. Propane/heating-oil prices are seasonal reported averages excluding taxes.
- Do not add a fixed bill component again if the supplied average already includes it. Actual tariffs may have tiers, minimum charges, demand charges, taxes and credits not modeled here.
- Heat-content examples are approximate. Confirm the correct fuel grade, composition, heat content, efficiency and unit against your own documents.
Sources, units and permitted reuse
- EIA reuse policy: EIA-produced data may be reused; source/date attribution is retained. No government endorsement.
- EIA heat-content and energy conversion examples. Fuel factors vary by product and year; enter your supplier factor where available.
- EIA Electric Power Monthly, Natural Gas data, and Heating Oil and Propane Update.
Calculations run on your device. No quantities or bill amounts are sent to EIA. Reference requests retrieve fixed public report URLs through BusCalc. Nothing saves automatically; downloaded receipts are unsigned, editable records of supplied inputs, not certified bills. Full specialty reports are not automatically included in paid packages.
