electrical costs for the fish hobby

[Ripdevil]

I am just wondering when running these tanks, how expensive my electrical bill will be when I add a certain sized tank depending on filtration and heating. Has anyone taken close note to how much these things increase your bills? I dont mean to sound cheap, but I have a 125g, 75g, and a 40g. and there are so many more fish that I wish to acquire, I just dont want to get carried away and be spending a fortune on my elec bill every month. . . .?
