Appliance Wattage Guide - Calculate How Much Energy You Use

Want to know how much wattage you are using - (wasting)? Check out a handy guide listing how much energy common appliances use not only when the run, but when you first start them up. Also, find out your running and starting watt needs for a generator.

This formula will focus on determining your running and starting watt needs for a generator.

The size of generator you need depends on your power requirements. Generally, a higher-wattage generator lets you power more items at once.

Select the items you wish to power at the same time. Fill in the running watts and additional starting watt requirements.

Add the RUNNING WATTS of the items you wish to power. Enter this number in the TOTAL RUNNING WATTS column.

Select the ONE INDIVIDUAL ITEM with the highest number of additional starting watts. Take this ONE NUMBER, add it to your TOTAL RUNNING WATTS, and enter it in the TOTAL STARTING WATTS box.

What’s up with Wattage – Frequently asked Questions

How many watts does it take to power basic items in an average size house?
In a typical home, essential items will average 5000 - 7500 watts of power to run.

What is the difference between running watts and starting watts?
Running, or rated watts are the continuous watts needed to keep items running. Starting watts are extra watts needed for two to three seconds to start motor-driven products like a refrigerator or circular saw, this is the maximum wattage the generator can produce

Why is only one additional starting watt item used to calculate your total starting wait requirement?Unlike running watts, starting watts are only needed during the first few seconds of operation. In most cases, only one item will start or cycle at the same time, therefore this is the most accurate estimate.

What if I can't determine the running or the starting watt requirement for a tool or appliance?
If the running watts are not on the tool or appliance, you may estimate using the following equation: WATTS =VOLTS x AMPS.
Only motor-driven items will require additional starting watts. The additional starting watts required may be estimated at 1 -2x the running/rated watts.
