Costco Pizza Nutrition: What You Should Know Before That First Bite
Costco pizza nutrition might not be top of mind when you’re biting into that hot, cheesy slice—but it probably should be. As a nutritionist (and yes, a fan of good pizza), I believe enjoying your favorite foods doesn’t mean ignoring what’s in them.

I remember grabbing two slices of pepperoni after a long Costco haul. They were delicious—crispy, gooey, everything you want in a food court pizza. But halfway through, my inner nutritionist kicked in:
“How many calories are in this?”
“Is this totally wrecking my macros?”

That moment led me to dig into the real facts behind Costco pizza nutrition—not just for me, but for everyone who wants to enjoy it without guessing.

In this guide, I’ll break down the calories, protein, carbs, fat, and sodium in each type of Costco pizza. You’ll also find comparisons with other popular chains, tips to make it fit your goals, and smart ways to store leftovers.

Costco Pepperoni Pizza Nutrition Info

Nutrient	Per Slice (1/8 of 18”)
Calories	850 kcal
Total Fat	36g
Saturated Fat	15g
Carbohydrates	92g
Protein	44g
Sodium	1,890mg

Note: Higher fat and sodium due to pepperoni, but also 44g of protein — ideal for post-workout recovery if timed well.

Combo Pizza (Where Available)

Nutrient	Per Slice (1/8 of 18”)
Calories	810 kcal
Total Fat	32g
Saturated Fat	13g
Carbohydrates	93g
Protein	42g
Sodium	1,760mg
Fiber	7g
Sugar	9g

Sadly discontinued in many areas, this fan-favorite had the most balanced macro and fiber profile due to added veggies. Combo pizza slices were a legend for a reason. With a combination of meats and a hearty serving of vegetables, each slice delivered a robust 810 calories—enough for a meal, not just a snack. The veggie toppings didn’t just add color; they upped the fiber to 7g per slice and helped balance out the macros. You’d get 42g of protein, 93g of carbs, and 32g of fat, with the extra veggies tipping the scales toward a more satisfying, nutrient-diverse bite. It’s easy to see why this option was beloved: the blend of flavors, the added texture from bell peppers and onions, and the ability to pair it with a crisp side salad or some steamed greens made it feel a bit less like pure indulgence. Of course, with 1,760mg of sodium per slice, it’s still a treat best enjoyed in moderation. For those who managed to snag a slice before the combo disappeared, it was a filling, flavorful meal—one that ticked more nutrition boxes than its cheese or pepperoni counterparts, all for the same unbeatable price.

Comparison with Other Chains

Chain	Slice Size	Calories	Protein	Carbs	Fat
Costco	1/8 of 18″	760-850	40-44g	92-94g	26-36g
Pizza Hut	1/8 of 14″	300	14g	34g	12g
Domino’s	1/8 of 14″	270	11g	33g	10g
Papa John’s	1/8 of 14″	290	12g	35g	11g

Summary: Costco pizza slices are literally twice as big. When adjusted for portion size, nutritional density is comparable.

Understanding Portion Sizes

• One Slice = 1/8 of an 18” Pizza (~310g)
• Twice the size of other chains
• Each slice is about 9 inches long
• Macronutrient density per ounce is similar to competitors

For accurate tracking: Treat one slice of Costco pizza as 2–2.5 regular slices from other brands.

How Costco Pizza Fits Into a 2,000-Calorie Day

So where does a Costco pizza slice land you if you’re tracking a standard 2,000-calorie target? In short: front and center. With each slice clocking in at 760 to 850 calories (depending on your topping of choice), that’s a whopping 30–40% of your daily intake in just one go.

Let’s put it into perspective:

• If you’re aiming for 2,000 daily calories, a single Costco slice often leaves you with just 1,150–1,240 calories left for the rest of the day.
• For comparison, grabbing a slice at Pizza Hut or Domino’s (about 270–300 calories per slice) uses up only about 13–15% of your daily goal, but remember, those slices are half the size.
• With 40–44g of protein and over 90g of carbs per slice, Costco’s pizza is essentially a full meal—plan your other food choices accordingly to stay balanced.

Bottom line: One slice can easily anchor a meal, but balance it with lighter, nutrient-dense options elsewhere to stay on target for your daily needs.

Expert Tips for Nutritional Management

Portion Control Hacks

• Cut slices in half
• Share a slice with someone
• Blot excess oil to save 30-50 calories
• Pair with a fiber-rich salad to stay full longer

Balancing Meals

• Eat lighter earlier in the day if you know you’ll indulge
• Add extra veggies on the side for volume without extra calories
• Drink a full glass of water before your meal to feel fuller

How Much Exercise to Offset a Slice?

Wondering just how much movement it takes to balance out those iconic, oversized slices? Let’s break it down with some real-life activity comparisons.

• Swimming Laps: A 150-pound person swimming at a moderate pace will torch roughly 400–500 calories per hour. That means you’d need to swim for about an hour—covering approximately 3,000 meters—to burn off the calories in one Costco pizza slice.
• Pumpkin Spice Latte (Grande): For comparison, swimming for around 30 minutes (1,500 meters) is enough to counteract the calories in a classic fall latte.
• Thanksgiving Dinner: Feeling ambitious? Burning off the equivalent of a hearty holiday meal (about 2,000 calories) would require a marathon swim of over three hours!

Quick Reference Table:

Food Item Calories Swimming Needed (Moderate Pace) Costco Pizza Slice ~700 1 hour (3,000 meters) Pumpkin Spice Latte (Grande)390 30 min (1,500 meters) Thanksgiving Dinner 2,030 3 hours (8,500 meters) >

Tip: Don’t sweat the math—consider simply fitting in a brisk walk, a bike ride, or any activity you enjoy. Pizza isn’t earned, but physical activity helps keep things in balance.

Healthier & Lower-Carb Options at Costco’s Food Court

If you’re looking to lighten up your Costco pizza run—or just want to keep your macros in check—there are a few easy strategies you can use right at the food court:

• Go Crustless: If you’re following a keto or low-carb diet, consider eating just the toppings (cheese, sauce, veggies, and meat) and leaving the bulk of the crust behind. It’s not fancy, but it’ll significantly cut carbs and calories.
• Double Up on Veggies: Ask for extra veggies where possible, or bring along a bag of pre-cut veggies to enjoy on the side. Bell peppers, onions, and mushrooms will boost fiber and help fill you up for fewer calories.
• Blot the Oil: Grab a napkin and gently blot excess oil—this simple move can shave off 30–50 calories per slice with zero flavor sacrifice.
• Pair with a Salad: Costco’s food court doesn’t always offer salads, but you can grab a bagged salad from the refrigerated section. Pair a smaller portion of pizza with a hearty side salad and skip the heavy dressings for a balanced meal.
• Split a Slice: Remember, each Costco slice is nearly double the size of most chain pizzas. Sharing a slice (or cutting it in half) instantly halves the calorie load and makes room for more greens on your plate.
• Hydration Trick: Drink a full glass of water before digging in—this simple hack helps control portions by curbing hunger and keeping you full longer.

With these tweaks, you can satisfy your pizza craving and keep your meal lighter, more filling, and balanced—without missing out on the classic Costco pizza experience.
