Costco Pizza Nutrition Overview
Calories Per Slice of Costco Pizza
If you’ve ever ordered a Costco pizza, you already know—each slice is huge. A single slice of Costco cheese pizza clocks in at approximately 710 calories, while a slice of pepperoni can reach around 720 to 750 calories, depending on oil content and topping density. The combo pizza, which includes meat and veggies, is slightly higher still, averaging 760–770 calories per slice.
That’s more than a third of the daily recommended intake for some people. Considering that a whole Costco pizza is cut into 6 extra-large slices (or 12 smaller ones), one slice can be equivalent to 2 regular slices from other pizza chains.
Macronutrient Breakdown: Carbs, Fat, and Protein
A closer look at the nutrition label reveals more than just calories. A slice of Costco cheese pizza typically includes:
- Fat: 28–30 grams
- Carbohydrates: 70–72 grams
- Protein: 36–38 grams
- Sodium: 1,500–1,700 mg
That sodium content alone nears your full daily limit. This breakdown helps explain why even one slice leaves you feeling full. It’s dense, carb-loaded, and loaded with flavor—thanks to Costco’s generous cheese and thick crust.
If you’re planning to enjoy a slice with dessert, consider balancing it with something lighter like this protein-packed cottage cheese cookie dough. It’s a great way to satisfy your sweet tooth while adding more protein to your meal.
You might also love pairing your slice with a lighter finish like strawberry fluff, especially if you want a less sugary, refreshing contrast after that cheesy richness.

Types of Costco Pizza and Their Calories
If you’re wondering how Costco pizza calories stack up between each type, you’re not alone. Every pizza option at the Costco food court brings its own flavor—and calorie load. Let’s break it down by type.
Pepperoni Pizza
The Costco pepperoni pizza is legendary, but it’s also the heaviest in calories. One extra-large slice delivers around 740 calories, with:
- 32g fat
- 75g carbohydrates
- 38g protein
The pepperoni’s grease soaks into the crust, increasing fat and calorie content. If you’re tracking Costco pizza calories per slice, this one’s among the highest. It’s delicious, but moderation is key.
Cheese Pizza
A single slice of Costco cheese pizza has approximately 710–720 calories. While it seems simpler, the calorie count is still significant because of the thick crust and heavy cheese layer:
- 30g fat
- 72g carbs
- 37g protein
Compared to other pizzas, cheese offers no significant savings in terms of Costco pizza calories, but it may be a better choice if you’re avoiding processed meats.Hearty and filling, each bite still delivers a hefty calorie boost
Combo Pizza (Meat & Veggies)
When available, the Costco combo pizza included sausage, pepperoni, peppers, and onions—all baked into the crust. One slice often exceeded 770 calories. Although it had vegetables, they weren’t enough to lower the total Costco pizza calories meaningfully.

How Many Slices Are in a Costco Pizza?
One of the reasons Costco pizza calories can add up so quickly is portion size. A standard Costco pizza is 18 inches across—massive compared to most takeout pies. It’s cut into 6 extra-large slices, though many customers choose to slice it into 12 smaller pieces at home.
Each original slice is equivalent to nearly two standard slices from a typical pizzeria, meaning when you’re eating just “one,” you’re getting double the calories and carbs. If you’re logging your food intake, always confirm whether it’s one Costco slice or a smaller portion.
A whole Costco cheese pizza contains about 4,320–4,400 calories total, depending on topping density. That means two slices can easily exceed 1,400 calories, nearly 70% of an average adult’s daily recommended intake.
Is Costco Pizza Healthy?
Let’s be honest: Costco pizza calories come from indulgent ingredients. With white flour crust, heavy cheese, and sodium-packed toppings, it’s not designed as a health food. One slice often contains:
- 30g+ fat
- 1,500+ mg sodium
- Over 70g of refined carbs
These figures make it more of an occasional treat than a regular meal. However, you can make smarter choices. Skip the soda, share a slice, and balance it with fiber or lean protein.
Costco Pizza Ingredients List
To understand Costco pizza calories, you need to know what’s actually in the slice. Costco doesn’t cut corners on ingredients—each pizza is loaded with quality items, but also lots of calories. Here’s a quick look at what goes into a typical cheese or pepperoni pizza:
- Enriched white flour dough
- Tomato-based pizza sauce (sugar, oil, seasoning)
- Whole milk mozzarella cheese
- Optional toppings: pepperoni (pork/beef), sausage, vegetables (onion, bell pepper, olives)
Costco’s thick crust already carries a hefty calorie load, but it’s the gooey layer of cheese that truly pushes the numbers up. More than half of the total calories come from refined carbs and fats, making each slice incredibly energy-dense.
Toss in toppings like pepperoni or sausage, and you’re looking at a serious jump in sodium and saturated fat. Even without those extras, a standard slice packs such a punch that many health-conscious eaters prefer to split it—or stick to just half.
Tips to Make Your Slice Healthier
You don’t have to give up your favorite slice to cut back on calories. Here’s how to cut Costco pizza calories without sacrificing flavor:
- Split a slice—grab an extra plate and enjoy it with a friend.
- Skip sugary drinks – Go with water or unsweetened iced tea
- Pair with fiber – A leafy green salad helps digestion and balance
- Avoid heavy desserts – Go for lighter options like strawberry fluff
- Plan your meal – Eat light earlier in the day to balance your intake
