Yes, it does. I used to leave mine on 24/7. Why…I don’t know.
I started turning in off before I went to bed and didn’t turn it back on until I got home from work. My bill dropped $25.00. While that is less than a dollar a day, I can think of better things to do with $25.00 than pay the electric company.

I doubt that the results would be noticable…maybe 50 cents a month depending on how much you use it. Your major appliances pull much more energy, so you would be more likely to save more money by turning down your water heater, or drying your clothes on a line rather than in a dryer.
If you are so inclined, you can figure out how many watts/hour your computer uses, and figure out exactly how much it costs to run your computer. It is just a simple math problem from there…
Hope this helps!

No. It takes less than a desk lamp. A laptop takes almost nothing. In point of fact, none of the electronic devices you use take enough power to make much difference. The biggest power users are heating and air-conditioning, followed by illumination.

I have been told in our area it saves 12 cents an hour to have it shut down.
This is from a man who does computer work..

Most newer computers have a 350-400 watt power supply, older ones have a 200-250 watt power supply. Since the wattage recorded is output and the power is being transformed down the output will probable slightly less than the power used. Assuming there is a 20% loss (pulled that number out of my ear) then you will be using somewhere between 240 watts and 480 watts an hour. You pay for energy by the killowatts per hour (1000 watt= 1 kw) 480 watts = .48 KW which can be multiplied by your rate per kw hr to determine the cost of operation.

Leaving an average computer "idling" will use about the same amount of electricity as leaving a 150 to 200 watt light burning constantly. If the monitor does not got to "sleep" it will use another 25-100 watts depending on the type and size.

I had a large electricity bill and contacted the Electricity Board in my State. They sent me a prospectus about how to save on electricity. One item said that leaving the computer on all the time adds $AS100 per year to your bill.
Hope this helps.
