how much does it cost to per hour to leave a computer on?

All it would be doing is downloaading.
Monitor would be turned off.

Most accurate way would be to measure current draw and work from there.
At a guess I'd be saying it'd work out to something like 100W, so about
2.5kWhr per day, but there's so many unknowns that you'd be better off
getting a measurement done. Do you know someone (a sparky?) with a
clamp-on current meter?

You can also just turn everything else off in the house, and use the
electricity meter that your electricity bill is based on. Somewhere on
it there will be an indicator of how many turns the disc makes per kWh.
Just measure the time for it to turn once, and do the sums. It shouldn't
take more than a few minutes with a typical meter.

Would take around three to four hours to use a Unit (one kilowatt-hour) of
power. Use the cost per Unit in your area to calculate hourly cost..

If its a notebook it will suck up 65-90 watts

If its a PC, all PC's have a 300-450 watt power supply.
But the average it would suck up is about 250 watts
Would do considerably more if Playing 3D games, > 300W
Each PC is different, graphics, disk drives, memory, CPU
A 17" monitor will suck up about 100 watts

I thin its about 12c Kilo watt hour so it would cost
3c Hour to run 250 watts.

is that all???

I thought it would be like 10 cents an hour.
Someone at work tried to tell me 4 cents an hour.

You'd be figuring about $2.40 per day?? Even my back-of-the-envelope
guesstimate is probably excessive on average, and it would be about
$0.40 per day (at about $0.15c/kWhr).

Cheers.

Unless it normally uses no power, in which case it won't help at all.
But the OP said he wouldn't have a monitor connected.

If the monitor goes into standby | energy saver | green mode it draws
~10 watts, when fully on is about 100 Watts. If you turned it off
would draw 0 watts, so 'yes' it would help if you 'tuen' it off.

If you have a 17" or bigger, I would never recommend turning it on/off at all
you will actually do more harm than leaving it on. The Power on surges are
enormous and will eventually blow the Power Supply.

Instead of showing a stupid screen saver (power waster) you should configure
it to turn the monitor off (energy saver mode).
