Real cost of running computers

The cost of my electricity has recently rocketed to £120 per month. As I don't heat or cook with electricity, I've been wondering how I can possibly use that much and I came across this calculation -

Personal Computer and Monitor (220+150)
= 370 Watts x 4 hours/day x 365 days/year
1000
= 540 kWh x 8.2 p / kWh
= £44.28 / year
Until recently I had 4 desktops on all the time, (2 members of the family now have laptops so the situation has improved) but 4 PCs on 24/7 according to this calculation are costing me £88.56 per month in electricity - this can't be right can it?

If one machine costs £44.28 a year then 4 machines will cost £177.12 which is £14.76pm

As a start I suggest you look here. My marginal rate per KWh is 5.83p

Monument - the original calculation is only for 4 hours use per day, my calculation is based on 24/7.
anskyber - have been looking at comparison sites but your rate seems much cheaper

Its npower and I am in Cumbria. It can vary.

I'm with npower too but live in Oxfordshire - the plot thickens!

And according to my recent bill's, the cost are going to increase even further, more so, over the winter months. Anyone know where I can get a steam, wood or candle powered computer?.

Mine is a "sign on line" tariff, slightly less than their standard rates. Here at least!

Drat! I'm having a poor morning. The price I quoted was from my September bill. I am now on 8.15p. Which is still the cheapest for me in this area. Apologies for the misleading post earlier.

click here for an electrical running cost calculator, it may help you calculate your running cost more easily?

And click here for a 'Watt' rating for your monitor etc.
