Unless you are very disciplined it probably wouldn't help, but it could help you understand how you failed to control it. It doesn't require math to remember to shut off lights and unused equipment. It makes a good math exercise to calculate how much it cost you to forget.

In order for math to help you control your electric bill you would have to know how many billable kilowatts you were using per day. There are some web pages out there that will give you a formula to figure that out.

wattage of appliance 1500 wats divided by 1000 = 1.5 kilowatts x the hours used a day times your rate per killowatt is how much you will be charged. And I did need math to figure this out. you can do the same thing by looking at the light bulbs you have to determin wattage and all your electric appliances but it would be a pain.

You don't necessarily have to know math to control your electricity bill as long as you recognize increases and decreases when you see them.

There are some simple ways to control your electricity bill:

1) unplug all small appliances, lamps, and electronics when not in use.

2) if you have a washer in the home and can easily get to its plug; unplug it when not in use.

3) turn off lights when not in rooms.

4) don't leave chargers for cell phones and other digital devices plugged in when not in use.

5) keep air conditioner set on 78 degrees in summer.

6) if you use electricity to heat your home, set it at 68 degrees or below during cold season.

2 +2 is always 4. This is important to understand when calculating electric bills. It could help you understand how to save money. Turning your lights off when you aren't using them is also helpful. Great Question!

Because if you know how to calculate your bill, approximate consumption and understand your bill you can see how or where you spend more and how to try to save some money. But also, as I did not long ago, after quite a lot of calculations and data for the last 2 years and looking at different tariffs from several gas and electricity suppliers, I swap suppliers and I'm saving some only now, approximately £5 less per month.

Let me give you a practical example.

First of all I'll explain how the electricity company calculates your bill.

Most electrical appliances have labels showing a number in Watts or Kilowatts. The Watt is a measure of power. 1 Kilowatt = 1000 Watts. If you have a kettle with 1200 Watts on the label, this is the same as 1.2 Kilowatts. The higher the rating, the greedier the appliance. The longer you run a power hungry appliance the quicker goes up your electricity bill.

Well, how fast does the electricity bill go up?

The utility company uses a measure called the Kilowatt Hour to calculate electricity bills. A kilowatt hour is a measure of the quantity of energy you consume in 1 hour.

In practice, you multiply the Kilowatt rating of an appliance times the number of hours it is used times the billing rate. I will use $0.3 per kilowatt hour as the billing rate. If I used my 1.2 Kilowatt kettle for 2 hours the number of kilowatt hours would be:

1.2 x 2 = 2.4 Kilowatt Hours

Therefore the bill would be:

2.4 x $0.3 = $0.72
