It's more, but it's not hugely more. I realize this differs in other places and E6 is pretty insane in Australia.
Yeah, we got it bad here. I've never done a direct comparison so may as well now.

Dead Link Removed (1 of 2 E6 labs left within 700km, the only Dip'n'dunk and Kodak Q-Lab left), all dev/sleeve, no mounting or prints:
E6 135-36 $13.60
E6 120 $12.10
C41 135-36 $12.10
C41 120 $10.80
There's another (cheaper) E6 lab here, at least there was last time I used them a year or two ago, and a few other 1-hour Minilabs for C41. But if I'm going to do something, I do it right and send it to Atkins if I'm not going to do it myself.
So all up:
In 35mm, that makes C41 from 58c to 73c per frame, E6 is 85c to 90c per frame.
At 6x6, that makes C41 from $1.60 to $1.80 per frame, and E6 is $2 to $2.10 per frame.
Yes, C41 prints cost more, and so do Slide mounts, but I don't really do either. Atkins do offer a scan/print service, but they charge pretty much the same for E6/C41 (E6 is a tiny bit higher), so that's not going to influence the final price-difference much.
I scan all of mine which costs the same either way (although E6 is a crudload easier to scan), some C41s I do print RA4 but it's a rare occurrence.
But then, price has never been a factor for me, really, in deciding between C41 and E6. I use RVP50 the most for the saturation, or switch to Ektar when there's a huge range of light. Those two make up 90% or so of all my colour. The other 10% is usually in a toy camera where I just buy whatever cheap expired crap I can get off fleabay. Once or twice in the last few years I've used Portra 160 and some Astia in sheets specifically for people.
In B+W I go more on price, eg I can't see much difference (for
my eyes and the way
I shoot and develop, ymmv) between HP5 and TriX, so I shoot whatever is cheaper on the day (usually HP5). Ditto in 100-speed, I've got bulk-rolls of Rollei Retro, TMX, FP4, because they were bargains at the time.
And mostly in the smaller sizes I'm not shooting for 'keepers' so I don't feel the need to perfectly calibrate every workflow for exactly repeatable results using the same film for 1000 cartridges.
