the actual wattage rating on the unit will not be accurate. I recently measured my pc consumption using a device you plug into the socket and then that measures the usage.

I was quite surprised at how much less my stuff actually used than I thought

Then of course your unit prices might be higher and lower rate or you may have a standing charge depending on your supplier.

I basically just use a unit rate of 10p per kwh this in the main is higher than my unit price but it may well be lower than your unit price again depending on your tariff
