How Many Calories In Costco Pizza Slice? | Real-World Numbers

Calorie Range By Slice Type

The food court offers giant slices cut from an 18-inch pie. A cheese slice lands near 760 calories, a pepperoni slice hovers around 710, and the combo clocks in around 760. Those figures come from nutrition panels gathered from store boards and public calculators that compile chain data. Portions are generous, so the range is higher than a typical corner pizzeria slice.

Costco Slice Calories & Macros (Per Slice)

Variety	Calories	Macro Snapshot
Cheese	~760	~40 g protein; ~30 g fat; ~80 g carbs; ~1,740 mg sodium
Pepperoni	~710	~33 g protein; ~28 g fat; ~77 g carbs; ~1,767 mg sodium
Combo	~760	~34 g protein; ~31 g fat; ~82 g carbs; ~1,942 mg sodium

Why The Numbers Move Around

Calories aren’t identical across warehouses. Differences in cheese load, oil on the pan, and how cleanly the pie is cut all nudge totals. A slightly smaller wedge trims some calories; an edge slice with extra crust can bump them up. Toppings matter too. Pepperoni brings fat but sometimes lands a touch lighter than the extra cheese in a plain slice. The combo’s veggies add bulk and salt from meats, which is why sodium spikes.

How Menus Present Slice Calories

Chain restaurants with many locations must display calories on menu boards. For pies, the rules allow listing calories per slice as long as the number of slices per pie is shown next to the figure. That’s why many boards show a single number right beside the item name rather than a range. You’ll also see totals for a whole pie when it’s sold as a unit.

Portion Size, Weight, And Cut

One pie is cut into six broad wedges. That cut size explains the calorie range compared with typical 8-slice pies at smaller shops. If a staff member trims a slice’s tip or adds a sliver, the number changes a bit, but not enough to swing the ballpark figures by hundreds.

How A Slice Fits Your Day

Think in terms of the day’s budget. A single wedge can take up a third of a 2,200-calorie target, or even more for smaller budgets. Protein is high for pizza, which helps with fullness, but sodium is up there too. If the rest of your meals lean fresh and lower in salt, one wedge can fit without blowing the day. Planning around daily calorie intake helps you decide whether to pair it with a salad, split the slice, or save half.

Cheese Vs. Pepperoni Vs. Combo: Picking Your Spot

Cheese keeps the ingredients simple. It often carries the most protein per slice and a touch more fat from extra cheese. Pepperoni brings a smoky bite with similar carbs and slightly less total energy than cheese. The combo piles on meats and vegetables; the calorie figure matches cheese, but salt jumps because cured toppings bring sodium.

Macro Differences That Matter

Protein helps with satiety during a long shopping run. Carbs deliver quick energy but can feel heavy if paired with a sugary drink. Fat content changes mouthfeel and fullness. If you want the most protein per calorie, split a cheese slice with a friend and add a side of fruit later. If you want a lighter feel, pepperoni may come in a hair lower on energy even with the cured meat.

Smart Ways To Trim Calories (Without Losing The Treat)

You don’t need to skip the food court. A few small moves cut energy load while keeping the taste. Share a wedge, skip the soda, or blot the surface oil with a napkin. Each tactic saves a modest amount; together they make room for dessert or an extra protein hit later in the day.

Practical Tweaks And Estimated Calorie Savings

Move	Estimated Savings	Notes
Split One Slice Two Ways	~350–380 kcal	Works for cheese or combo wedges
Blot Surface Oil	~20–50 kcal	Varies by pan oil and cheese melt
Skip Sugary Soda	~200–300 kcal	Choose water or diet soda
Pair With A Side Salad	Indirect	Fiber helps you stop at one wedge
Order Whole Pie, Cut Into 8	Portion control	Smaller wedges = easier tracking

Reading Store Boards With Confidence

You’ll usually see a single large number next to each slice flavor. That figure reflects the standard cut and recipe. When a board shows per-slice energy, it should also make clear how many wedges the pie yields. If your location displays a whole-pie figure instead, divide by six for a quick slice estimate. If you’re counting closely, snap a photo of the board to log later.

What About Regional Differences?

The recipe is standardized, but dough proofing time, sauce ladle depth, and oven belts can change slightly by region. Most warehouses still land within the same ballpark. If you notice a thicker cheese cap or a darker bake, expect a minor swing in fat or moisture, not a full category jump.

Pairings That Keep You Satisfied

Balance the wedge with protein and fiber elsewhere in the day. Greek yogurt at breakfast and a produce-heavy dinner bring the day’s nutrients back in line. If you want a drink with the slice, unsweetened iced tea or water keeps energy in check. If you want a treat, a fruit cup or a small soft-serve swirl fits better than a large soda.

Whole Pie Math For Parties

Hosting after a big shop? One 18-inch pie cut into six hefty wedges offers roughly 4,200–4,600 calories total, depending on flavor. That gives you a handle on how many pies you need for a crowd. Add a tray of cut veggies and a light dip and most guests will stop at one wedge.

Frequently Missed Details

Protein Is Surprisingly High

That’s why one wedge often holds you over during a long day of errands. It also means you can keep the rest of your meals lighter without feeling shortchanged.

Sodium Deserves Attention

Numbers often sit between 1,700 and 1,900+ milligrams per wedge. If you have a sodium target, drink water and steer the rest of the day toward lower-salt choices like fresh fruit and plain grains. You’ll enjoy the slice and still hit your goals.

Ordering Tips That Actually Help

• If you’re solo, ask for a box and save half for later.
• Grab a fork and eat the topping and cheese first, then stop if you’re satisfied.
• Pair it with sparkling water for the “treat” feel without extra energy.
• Walking the lot after lunch adds steps while the cart is full.

Make The Numbers Work For You

A wedge can fit in many plans. Use the board figure as your anchor. Match the rest of the day to your needs with lean protein and produce, and keep drinks simple. If you like structured targets, a short stint in a calorie deficit during the week balances a food court lunch.
