You have to change your preferences in Photoshop's preference dialog --

Go to File>Prefs>FileHandling and turn ON Image Previews -- Ask When Saving.
If this is set to Never, you won't see the option when you SaveAs... The
image preview is what jumps the file size, especially with a small image.

If you have your prefs set to save all of the icons, previews and a profile,
it will add size to a file. Since these addons are generally about the same
number of bytes regardless of the size of the file, you'll see a bigger jump
in size on a smaller file, proportionally.

I tested this informally on a Mac, with an 8Mb file reduced to a JPEG. With
no profile and no image previews of any sort, at JPEG 11, it registered
1.203Mb in the PS dialog box, and 1.248 actual as measured in the Info box.

The same file, with a profile and all the image previews, including Full
Size, was 1.337Mb, about 110Kb more. The time estimate doesn't account for
the additional data, only the data in the JPEG file itself.

Using Save for Web, and optimizing for a file size of 1203 to roughly match
the same level of compression yielded a slightly smaller file, about
1.150Mb. 

Note that Save for Web does not preserve the IPTC data, but Save As does.
This is due to the fact that Save for the Web is usually used to slice
images, and to get the file size as low as possible. This is by design, I
believe.
