Also, energy costs vary from region to region. If you want to know how much

electricity your space heater uses, you'll need a recent electric bill to work along

with the example.

You'll need two pieces of information from your bill; the amount due for the

current month and the number of kWh (kilowatt hours) used. You can find the

kWh usage in the meter reading section of your bill.

The amount of electricity used by a space heater is measured in watts and

expressed on your utility bill as kilowatt hours (kWh). Technically speaking,

kilowatt hours is the product of power in kilowatts (1000 watts) and time in

hours - not kilowatts per hour. But for the purposes of this explanation,

kilowatts per hour is sufficiently accurate.

**Step 1. Determine cost per kWh (kilowatt hour)**

The easiest way to do this is divide your total current monthly bill by kWh

usage.

**Monthly bill ÷ kWh usage = Cost per kWh**

This isn't the most accurate way to determine the cost per kWh because all

electric bills include a customer service charge of $6 or more which in effect

increases the cost per kWh by 5-10% depending on the amount of your bill. So

it's up to you, you can either use the full billing amount or subtract the service

charge before you divide it by the kWh usage.

For the examples here I'm going to include the monthly service charge because

you really don't have the option to pay it. I typically spend around $69 a

month for 438 kWh of electricity. When I plug the numbers into the formula

above it looks like this:

**69 ÷ 438 = 0.158 **So my cost per kilowatt hour is slightly less than 16¢.

Not coincidentally, your cost per kWh equals the cost to run a 1,000 watt

space heater for one hour.

**Step 2. Determine the cost to run any wattage space heater per hour**

**Cost to run space heater per hour **= **heater watts x .001 x cost per kWh**

For a 1,500 watt space heater at a rate of $0.158 per kWh, the formula looks

like this:

**1,500 x .001 x .158 = .237**, or **24****¢**** per hour** rounded up.

Some personal space heaters, like the Toasty Toes Footrest heater, use only

90 watts of power and cost practically nothing to run:

**90 x .001 x .158 = .014 or 1½¢ per hour rounded up.**

**Step 3. Estimate monthly cost to run**

Let's say I plan on running my 1,500 watt space heater every day of the month

for 6 hours. This is how to figure out how much to budget for:

**$0.24 (per hour) x 6 (hrs) x 30 (days) = $43.20**.

**How much will you pay?**

Electric rates in New England are some of the highest in the country. The

national average according to the EIA is 12½¢ per kWh. So whatever the rate

is in your area, you now have the know how to budget for monthly space

heater use and avoid an unpleasant surprise when you open your electric bill.

Most electric space heaters and

electric fireplaces are rated at

1,500 watts. This would be the

"high" setting on the heater.

However, most space heaters

also have a "low" setting or a

thermostat, so for the sake of

simplicity we'll assume the

space heater in this example is

operating continuously at the

full power setting of 1,500

watts.
