The following calculators are provided to help you determine the size of generator required for your specific application. Other calculators on this page are for unit conversions and other power related calculations.
Use the calculator below to estimate electricity usage and cost based on the power requirements and usage of appliances. The amount of time and power that each appliance is used varies significantly between households, so for the best results, adjust the usage for each appliance to most accurately reflect your personal usage.

The intent of the power calculator is to provide guidance for estimating the electrical and heat loads for typical operating conditions. It should not be used to calculate power or HVAC requirements. Instead, please use the appropriate site planning guide to allow for proper allowances.
You MUST allow electrical and cooling headroom for unforeseen circumstances, component upgrades, and increased computational loads. Please allow for worst-case power conditions. Actual power consumption will vary from the sample workload used in the power calculator. These include, but are not limited to, the factors below. Each of these factors may cause significant differences in power consumption:
The "Sample Power" results shown (if using 100% workload) represent server power consumption measurements with CPUs at 100% utilization running SPECjbb2005. HPC workloads may consume more power than the commercial workload used in this calculator. If shown for this calculator, the "Active Idle Power" results represent power consumption measurements taken from servers with operating systems booted and stabilized, yet running at minimal utilization. Sample results shown are representative of measurements taken with room temperatures below 25C. System power can vary depending upon hardware/software configurations and environmental conditions. For precise results, actual measurements based upon the exact hardware/software/environmental conditions are recommended.

This rate calculator estimates annual electricity costs for battery electric truck and bus deployments at a given utility meter. For ease of use, the calculator is pre-populated with several utility rate schedules, charging strategies, and charging time periods. The user can select from these or add additional, rate schedules, charging strategies, and charging periods as needed.
It's easy to determine the costs of running your appliances. You can use this tool to determine the approximate energy usage and cost of most major electric appliances. The electric appliance calculator is an estimate cost of appliances. Actual costs may vary between customers. For the most accurate estimate of your home, complete an energy audits.
This calculator presents all the levelised cost of electricity generation (LCOE) data from Projected Costs of Generating Electricity 2020. The sliders allow adjusting the assumptions, such as discount rate and fuel costs, and all data can be downloaded in CSV format.
Ever wonder how much it costs to run your ceiling fan all day? Want to know how that compares to using your window air conditioner? Our easy-to-use power calculator can show you just how much electricity your household appliances use.
This electrical power calculator helps you compute the power consumed by electrical devices. Do you want to know how to calculate electrical power? Are you wondering: what is the power factor? Just read the text below to find out.
RMS is a square root of the mean of squares of numbers (see the root mean square calculator for more). The commonly referred voltage of electrical outlets (230 V in the EU and Australia, 110 V in the USA and Canada, 100 V in Japan) is the RMS voltage.
The power factor depends on the device. For a device that is purely resistive, like an electric kettle or an electric heater, the power factor is 1. A device with inductive or capacitive elements puts the current and voltage out of the phase. This makes its power factor less than 1. Check out the power factor calculator to learn more.
To compute the electrical power, you have to specify the current, voltage, and power factor of the item. For devices connected to electrical outlets, the voltage is just the voltage of the domestic power. The current drawn by the device can usually be found either marked on a plug or somewhere on the device.
The data provided is for reference only. Actual values may vary based on manufacturing tolerances, cable assembly length, connector performance, actual operating frequency, and measurement accuracy. The calculator will only return data for frequencies below the cutoff frequency of the cable.Note that the power handling calculation is based on controlled conditions, including a temperature of 25C, sea level, and a still air (natural convection) environment. Power handling may be limited by the connector choice. Please note that the results presented here are not a guarantee of performance and are for reference only. For results tailored to your specific application, please contact our applications engineering team.
This tool uses basic information about your driving habits to calculate total cost of ownership and emissions for makes and models of most vehicles, including alternative fuel and advanced technology vehicles. Also see the cost calculator widgets.
This app uses the calculation requirements found in the 2017 National Electrical Code to determine the ampacity of insulated conductors and certain cable-type wiring methods. This calculator also complies with the 2020 NEC requirements. Certain installations (such as cable trays and medium-voltage conductors) are not included in this app. Insulated single conductors are assumed to be installed in conduit or direct buried. All calculations assume a voltage of no more than 2000 volts and that the appropriate NEC requirements are followed by the installer, engineer or other responsible party. For more information on ampacity calculations, please consult our technical resources.
Note: The calculator will permit choosing NM-B and UF-B up to 2 AWG. NM-B is permitted to be manufactured with conductors as large as 2 AWG, but multiconductor UF-B is limited to conductors no larger than 6 AWG by the UL standard.
Power is personal. Depending on how much electricity you use and when you use it, one price plan may suit you better than the others. Use our calculator to see what your total bill would look like under Time-of-Use (TOU), Ultra-Low Overnight (ULO) and Tiered prices, taking into account the other rates charged by your electricity utility (Delivery and Regulatory) and the Ontario Electricity Rebate.
Compare your current bill from your local utility with what to expect if you sign an energy contract with an energy retailer (also called an electricity retailer or a natural gas marketer). The bill calculator uses the regulated rates for each utility in Ontario. You can enter the contract price offered by the energy retailer to compare.
So that we can focus all our efforts on our new application, we have retired our myElectrical.com cable sizing calculator.We recommend you now use our main cable sizing application over at myCableEngineering.com.
To find out how many watts of electricity a device is using, just plug the monitor into the electrical outlet the device uses, and then plug the device into the monitor. It will display how many watts the device uses. If you want to know how many kilowatt-hours (kWh) of electricity the devices uses in an hour, or a day, or longer, just leave everything set up and read the display later.
Most people think electrical upgrades are needed if they add electric appliances, but this can be avoided with thoughtful selection of efficient products or by using load sharing devices. Homes have access to a set amount of power through the service wire from a nearby power pole. For example, a service wire may provide 24,000 Watts (100 Amps at 240V). Choosing power efficient appliances can help you avoid upgrading the utility service wire and your circuit breaker panel.
Share amperage between major appliances to better allocate circuit panel breaker capacity
Below is an example of how the main electrical panel in 2,000 square foot home might look, after the home is converted from gas to all-electric.
This calculator provides the required electrical power (power output from the amplifier) to produce a desired Sound Pressure Level (SPL) at a given distance, along with an amount of headroom to keep the amplifier(s) out of clip.
Many people don't realize that a transformer labeled for use with a specific voltage will work just as well at other voltages. This calculator provides power delivered from a transformer tap when driven with other than the rated voltage.
