Can't tell you, but mine is on 24/7 apart from restarts, and it does not result in excessive bills. I would think it's about the same as a TV, maybe less.

(Watts x Hours Used / 1000) x cost per kilowatt per hour = total cost.

Your PC will probably use around 100-200 watts depending on the age, components and screen used.

12.88p per KWH is the Higher Rate charge from NPower on one of my bills. So

200watts x 4 hours / 1000 = 0.8

0.8 x 12.88 = 10.304 pence for 4 hours or 30.912 pence for 12 hours.

I think thats how it works. (if I did my number crunching correctly!) And that is based on a power hungry machine on the higher rate charge. So It's likely your charge will be MUCH less. Hope that helps
