how much does a voltage regulator consume?

I have appliances that are plugged to a voltage regulator 24 hours a day. One is used to convert 110 to 220v. The other one I used for safety puposes from surges or low voltage. If these are idle (the appliance is off) but always on, how much would it consume? If it is on, what difference will it make on an appliance plugged directly to a 220v source and one that is plugged to a voltage regulator? It just says 500W for the other and 1000W for the other, but I think it's just the capacity and not the actual consumption.

It seems with the very efficient regulator these days, 90% eff is typical. e.g. If I pay P1000 a month for a certain appliance, perhaps P100 is wasted ... not so bad ... What do you think?

Thanks for your response, Ruperto. However, I need a measured wattage value (oh, i forgot to mention wattage consumption) so I can justify the existence of my voltage regulator vs plugging it directly to a 220v outlet.
