Is there a list, chart or something that gives a estimate for the life of a barrel for each centerfire caliber? I know that there is no way to know down to the last shot due to factory loads, reloads, number of shots per hour, etc. I was just wondering about a rough guesstimate.

Not that I have ever seen.
You can fairly well judge it by just looking at the cartridge though.
Big-Bore's like the 45-70 and low pressure rounds like the 30-30 would be indefinitely long.
Medium capacity rounds like .223, .308, and 30-06?
Perhaps 5,000 - 8,000 before accuracy would seriously suffer for normal uses.
Over-bore calibers like the high-velocity varmint calibers .22-250 or .22 Swift, and the big small bore Magnums like the .264 Mag or 300 RUM could be less then 2,000 rounds.
In short, the calibers that burn a whole bunch of powder, and push it through a smaller hole burn up barrels much faster then better balanced calibers.

There is a little spreadsheet at:
http://accurateshooter.wordpress.com/2009/09/23/handy-excel-formula-predicts-useful-barrel-life/
It is based on benchrest accuracy expectations and will give a lower number than you might expect based on less demanding uses and Internet Expert Prognostications of 10,000 round barrels.

I wouldn't bother with arbitrary add-ons to an already arbitrary formula.
As I told the other guy, shoot the gun on a target every once in a while and when the holes get too far apart to suit you, the barrel is shot out.
The Army Long Range team was changing out 6.5x284 barrels every 850 shots, even though most sources say they are good from 1000-1200, maybe more if you set the barrel back to get a clean throat before it fails.
I saw a .308 fail to last from 4600 to 4700 shots. The guy brought it to a Long Range match with 4600 on it and it would not stay on the 6 foot square backer at 1000 yards.
Hatcher said that Springfield test barrels were still shooting to mil spec at 6000 when they were changed out as a precaution.
NRA once printed a report showing 30,000 rounds with acceptable military accuracy from a FN FAL in Norwegian service.

Ignoring factors like barrel material quality, rifling type, bullet jacket material, bullet lube, load hotness, and anything else besides the bore size?estimate for the life of a barrel for each centerfire caliber?
Sure, your barrels will last for as many rounds as the bore size in millimeters multiplied by your waist size in centimeters.
