Hi. 

Below is my rough guess.

  • Generally, industry put 11 oz  – 15.5 oz on an 18″ pizza
  • Most common cheese to put on pizza is mozzarella.
    • Pizza makers mix different cheese varieties.
    • I don’t know exactly what kind of cheese mix Costco is using – but mozzarella is my starting point to guess.
  • 1 oz of mozzarella cheese has  78 calories.
  • So, my rough guess..
    • A whole Costco pizza has 858 – 1209 calories just in cheese
    • A slice of Costco pizza has 143 – 201 calories just in cheese
