Do iMac's and LCD's cost much to run?

How much would it roughly cost to run both for 10 hours per day 7 days a week?

a 40 inch LCD and 22 inch iMac

For the iMac you can work it out from here-without knowing your unit kWh cost and precise model, no-one can do the calculation for you. But on a 21.5 inch Mac it's little more than a light bulb, even at 100% CPU running.

For the monitor, look at the rating plate and it should tell you the power consumption.

Is there any website to put in the watts and it shows you how much it uses a hour/day/week/month/year?

The simple answer is: not really. Modern LCDs draw minimal power, even larger ones. Computers rarely draw over 100 W unless you're using a beefy graphics card for gaming or workstation tasks, so even being on all day wouldn't cost more than 20p.

If you know the wattage you've already got the anwer. 100W will consume 0.10kWh per hour, or 1kWh in 10 hours. Multiply by the unit rate you pay and you have the answer. So 10 hours on your iMac at a unit rate of 12p per kWh would cost 12p per day.
