I ate one slice of a costco combo pizza.I bought the whole pizza not the slice,however. im confused. about how much calories it contains since it says 680 calories.It seems like too much is this actually. true?It was a very small slice

That's the nutrition info Costco published for a 10.7 ounce serving. A lot of people have taken photos of the pizza and posted them online, and judging by those photos it's commonly cut into 12 slices. I agree that 680 calories per slice seems high for 1/12 of an 18" pizza.

Let's compare it to a similar 16" Papa John's pizza based on that online nutrition info.

Papa John's The Works 16" = Ten 172 gram slices at 350 calories each = a 1720 gram pizza with 3500 calories

Costco Combo 18" = Twelve 303 gram slices at 680 calories each = a 3636 gram pizza (8 lbs?) with 8160 calories

Using some quick geometry, an 18" pizza is 25% larger than a 16" pizza. Yet, on paper, the Costco pizza is over 100% larger. It doesn't add up.

Using Papa Johns as a reference, one would expect the Costo pizza to be 4375 total calories. (That's 3500x1.25.) Cutting it into roughly 6 - 8 slices (instead of 12) would get in the ballpark of 680 calories per slice.

Somebody should head to Costco and weigh the pizza, or at least a slice from an evenly cut pizza, and report back on that weight along with how many slices were in the pizza. I'll speculate that the 680 calorie and 10.7 ounce serving size was calculated on a lower number of slices per pizza, while they cut them into 12 slices in the stores. If so, each 1/12 size slice is likely around 340-450 calories.

Here's the published Costco data: https://docs.google.com/file/d/0B7SwqP0b-svxRmtOeXhzY0NUaENvdGRaeUZld19nUQ/edit?pli=1

Perhaps the pizzas sold by the entire pizza are cut into more slices (12) than the pizzas cut to be sold by the slice. That would explain why the "per slice" slice has so many calories and much more than what the original poster thought hers should have based on its size. (She said hers was purchased by the pizza.) I have now thought more about Costco pizza than anyone ever should.
