Your meter calculates costs based on a per Kilowatt hour (kWh) basis. A kWh is based on 1000 watts of power being used for one hour.

By reading your meter daily and using a little bit of simple math, you can help plan your electric bill each month. In times of extreme heat or cold, reading your meter each day can help you conserve energy and minimize weather-related usage.

Start by determining how much your ideal electric bill would be and use this formula so you can figure out how many kilowatt hours you can use each month.

• Budgeted Amount divided by 0.11 (all electric) = Budgeted kWh
• Budgeted kWh divided by 30 days = Daily kWh usage goal

For Example, if you want your bill to be no more than \$150/month,

• \$150 divided by 0.11 = 1,364 kWh
• 1,364kWh divided by 30 days = 45 kWh per day

To monitor your daily usage, read your meter at the same time each day and subtract one number from the other. This will give you your daily kWh usage.

With this in mind, start by getting some idea of how much each appliance typically uses.

24-Hour Equipment

Home or office, a refrigerator is always on. At 9 cents per kWh a 180-Watt Refrigerator costs \$11.66 per month.

Frequently Used Electric Equipment

Lights, air-conditioning in summer, heat in winter, TV sets and computers are among the devices we power-up everyday often for hours at a time.

Routine Short Use Daily Electric Equipment

Toasters, microwaves, hairdryers, and battery chargers are examples of the types of electric equipment we use daily but for short periods

# Household Electric Usage

To calculate the exact usage of an electrical item, use this simple formula.

• Wattage divided by 1,000 = kW
• kW times hours run per month = kWh
• kWh times 11 cents = monthly cost

For example, a 100-watt light bulb runs 300 hours per month (10 hours per day).

• 100 watts divided by 1,000 = 0.1kW
• 0.1kW x 300 hours = 30kWh per month.
• 30kWh x \$0.11 = \$3.30 per month

These charts provide an idea of how many kWh per hour typical household electric things consume.
