Yes, for a medium or large group, and the arithmetic is simpler than most people make it. A Costco party platter costs what the tray costs, and the number that matters is that price divided by the people you actually feed. Most sandwich platters land around two to four dollars a head, with shrimp and charcuterie trays running a little higher.
What is a Costco party platter, exactly? It is the pre-made tray from the deli or the refrigerated grab-and-go cases: sandwich and wrap platters, shrimp trays, sliced meat and cheese trays, vegetable and fruit trays, and the frozen appetizer trays you bake at home. Sizes run from a small tray aimed at a dozen guests up to a large one built for thirty.
Pricing is worth 20 to 30 percent less at warehouse clubs than at a standard grocery store, according to family-reunion budgeting guides, and party food is exactly the kind of bulk purchase where that gap shows up. The catch is the fee structure, not the food.
Every number here is dated. The serving counts and price bands come from published Costco appetizer guides, retailer listings and member reports checked in October 2026, and older figures are labelled as historical so nobody plans a party around a decade-old number. Costco pricing also varies by warehouse and by region, so treat all of it as a starting point and confirm at your own warehouse.

Is Costco’s Party Platter Worth It? Price Breakdown
Worth it when three things line up. The tray’s stated servings roughly match your headcount, you want zero cooking, and the tray is doing the work of a meal or most of a spread. Not worth it for a dinner of six. Not worth it when the group is large but the platter is one small item on a table already full of sides.
The single most useful habit is dividing the price on the tag by the number of people who will actually eat. That is the whole verdict, and everything below is the detail behind it.
| Platter | Stated servings | Where the figure comes from | Best fit |
|---|---|---|---|
| Assorted sandwich platter | 24 to 28 servings | Current Costco appetizer guide, checked October 2026 | Game-day spread, office lunch, holiday open house |
| Artisan sandwich platter | 18 to 20 guests | Promotional deli listing, order with 24 hours notice | Dinner party, shower, reception |
| Regional sandwich tray, three flavours | 12 to 18 servings | Costco Canada listing | Groups of 10 to 16 |
| Sandwich tray, historical baseline | 15 to 20 people | RedFlagDeals thread, 2015. Treat as an old data point, not a current price | Reference only |
| Frozen wing tray | 70-plus wings, roughly 8-pound tray, with four cups of ranch | Costco-Insider item listing | Anything where you have an oven and 40 minutes |
| Shrimp cocktail, charcuterie, sushi and fruit trays | Read the case label; selection and sizes change by warehouse and season | Deli case and app listing | Adding a centrepiece to a table that already has sandwiches |
Those serving counts come from labels, current listings and member reports, not from my own estimate. A Costco party platter serving count printed on the case is always the more reliable number for your warehouse, and it takes ten seconds to read.
Notice what the table leaves out. Drinks, ice, plates, napkins, serving utensils and delivery charges all sit on top of the tray. A Costco party platter price is a food price, not a party budget, and hosts who forget the gap between those two numbers are the ones who end up surprised.
How to Calculate the Real Cost per Person
The Costco party platter formula
Take the price on the tag and divide it by the number of guests. That is the advertised cost per person, and it is where most people stop.
Here is the version that survives contact with a real party. A sandwich platter tagged in the low fifties for 24 to 28 servings works out at roughly two dollars a head. A shrimp tray running in the eighties across 20 to 25 servings lands closer to four. Same table, same guests, a two-dollar swing per plate that comes entirely from which tray you picked.
What stated servings really mean
Adjust twice. First for appetite, because the serving count on the box is generous and members report real consumption running meaningfully lower than the label whenever guests also have chips, dips and something else to eat. Plan on roughly one full serving per person plus a cushion, and any cushion becomes next-day lunches rather than waste.
Second for the fees nobody prints on the tray. Delivery through Instacart adds a service fee and a tip, and on a small order those can erase the per-person saving entirely. And if you are not already paying a membership, fold a share of the annual fee into a single-party total, and the tray stops looking like a bargain. A member who would shop there anyway pays nothing extra for the platters, which is the real reason Costco wins on price.
| Guests | Platters to plan | Servings per person | What to add |
|---|---|---|---|
| 10 | 1 smaller tray, or 1 large with plenty to spare | About 1.2 to 2.8, depending on tray | A fruit tray, so you are not serving sandwiches only |
| 30 | 2 sandwich platters | 48 to 56 servings, so roughly 1.6 to 1.9 each | One veggie or fruit tray, one dip |
| 50 | 2 large trays plus 1 smaller tray or 1 shrimp tray | Just over 1.5 each with a cushion | One non-sandwich item; variety matters more than volume at this size |
Two platters for 30 guests is the build most hosts land on, and it holds even with a second round of chips going around. The one-tray-for-ten case looks wasteful on paper, but it is not if you plan to eat the extra portions for lunch, which changes the per-person number more than any tray swap will.
What Size Platter Fits Your Party?
Match the tray to the headcount, then check four things: how many other dishes are on the table, how long the party runs, how hungry the crowd is, and whether you want extras to come home with you.
Under 12 people, take the smallest tray you can find. Between 12 and 20, a standard sandwich or wrap tray does it. Between 20 and 35, two trays with different fillings beats one tray of everything, because it also solves the guest who does not eat one of the fillings. Between 35 and 60, go with two or three trays plus one non-sandwich item.
Other food changes everything. A platter that is the main event needs roughly double the per-guest amount of a platter sharing a table with wings, dips and dessert. A two-hour open house eats less than a five-hour one, and a crowd that skipped lunch eats a great deal more than a crowd that did not. I have watched a 20-person group clear a 24-serving tray in about forty minutes, and the same tray sit nearly full for three hours at a standing reception. The variable is not the tray, it is the crowd.
Dietary coverage is the other thing to plan for. Sandwich trays rarely solve a shellfish, gluten or vegetarian restriction on their own, because the fillings are mixed and the labels do not break them down piece by piece. Pairing a sandwich tray with a vegetable tray, a fruit tray and one clearly labelled specialty item usually costs less than a single custom tray and wastes less food. For a table with several restrictions, that math matters more than the per-person number.
What Affects the Price and Value?
Package size is the biggest driver. Platter price scales with tray size far faster than it scales with quality, so the per-person number improves as trays get larger. Ingredients come next: shrimp, seafood and artisan sandwich components push a tray up a tier, while standard deli meat and wrap platters sit at the bottom.
Specialty combinations carry the widest regional spread. Sushi, charcuterie and seasonal platters appear at some warehouses and not others, so the same item can be priced very differently two warehouses apart. Seafood pricing in particular swings more than sandwich pricing.
Membership is part of the value, not a separate line. Prepared food pricing is tied to your membership status, which is exactly why the per-person number only works for members. End-of-day markdowns on prepared food are common, and a discounted tray costs the same per person as a full-price one, so there is no arithmetic reason to wait.
Order minimums matter more than most people expect. Delivery adds a minimum plus fees, and crossing that minimum changes the per-person math more than switching from a sandwich tray to a shrimp tray does. Under roughly 25 to 30 guests, picking up usually costs less than having it delivered.
Two things change the value without changing the price. Freshness: read the use-by date on the case and buy as close to serving day as the 24-hour notice allows, because a platter that sits past its date is a bad deal at any price. Serving convenience: move the food onto your own platters or a cutting board at home. It costs nothing and makes a warehouse tray look catered.
Storage follows the label on the tray. Keep it refrigerated at or below 40°F (4°C), and do not leave it unrefrigerated longer than two hours before serving, or one hour if the room is above 90°F (32°C). Sandwiches, cut fruit and shrimp are perishable, so use the remainder within three to four days or freeze it. See our sandwich guide for the same food-safety basics on homemade trays.
Ways to Save on Costco Party Platters
Size to the real headcount, not to the label. The stated serving count is a ceiling, not a target, and the single biggest saving on this purchase is choosing one tray smaller than the label suggests.
Let the tray be the meal. Every side you drop is money back, and a platter paired with chips, dips and dessert for 50 people is three purchases where one was enough.
Use the 24-hour notice to compare rather than to rush. The deli asks for about a day’s notice on party platters, which gives you time to look at the case, check the use-by dates on what is actually there, and call a nearby warehouse if your first choice is thin that day.
Pick up instead of ordering delivery for anything under roughly 30 guests. The service fee and tip on a small order routinely cost more than the difference between two trays and one.
Do not hang the membership fee on a single party. It only makes sense if you would shop at the warehouse all year anyway. For one event, compare the total against a local deli tray for the same headcount.
Plan the storage before you buy, not after. Decide whether the extra portions become next-day lunches, a freezer item, or nothing at all. Buying two trays to hedge when one tray plus a fruit tray would do is the most common way people overspend here.
Buy on a markdown if the date is close. The per-person cost is identical to a full-price tray, and the tray you will actually eat tomorrow is worth more than the one that looks newer.
Frequently Asked Questions
How much is a Costco party platter?
A Costco party platter price depends almost entirely on size and type, and it varies by warehouse. Sandwich and wrap platters occupy the lower end; shrimp and charcuterie trays sit at the upper end, and seasonal items swing the most. Rather than trust a national figure, read the tag on the case at your own warehouse or in the app, and note the servings printed beside it. That pairing is the only number that actually matters for your party.
Is a Costco party platter cheaper than a deli platter?
Usually, for 20 to 40 people, and usually not for fewer than 15. Club-store prepared food is priced to move volume, and a single deli tray rarely carries a discount at that size. For a small group the deli often wins because its per-person price scales down rather than up. For anything large enough to trigger a caterer’s minimum order, a Costco party platter is the cheapest credible alternative on the table.
How many people does a Costco party platter serve?
Read the servings number, then discount it. A large sandwich tray is commonly labelled for 24 to 28 servings, a smaller one for 12 to 18, and a deli-listed artisan tray for 18 to 20 guests. Real parties run lighter than labels because guests eat around the tray, so plan on roughly one full serving per person and treat anything above that as insurance rather than a requirement.
Are Costco party platters good for a birthday party?
They work well for a birthday party, as long as sandwiches are not the whole plan. A 24-serving tray covers a room of 20 comfortably and leaves a few portions behind for the next morning. For a kid-heavy crowd, add a fruit tray and one sweet item, and skip strong pickles or heavy condiments, which tend to go untouched. Adults eat more of the plain sandwiches than you would expect.
Can you order Costco party platters in advance?
Yes, and you generally need to. The deli asks for about 24 hours of notice on party platters, which is usually a phone call or an order through the site. You can pick up in person or go through Instacart, with delivery available in many areas, so ordering a day ahead also gives you a choice of channels. On busy weekends the popular trays go fast, so keep a smaller tray in mind as your fallback.
How long can an unopened Costco party platter be stored?
Follow the use-by date printed on the tray, and buy as close to serving day as the 24-hour notice allows. Store it refrigerated at or below 40°F (4°C) in the sealed package, and use it within three to four days of purchase. Do not leave it unrefrigerated for more than two hours before serving, or one hour if the room is above 90°F (32°C).
Bottom Line
Buy a Costco party platter when the stated servings roughly match the number of guests, the tray is carrying the meal or most of the spread, and you are picking it up yourself. Before you buy, divide the shelf price by the real headcount rather than by the label, add delivery charges if you are using them, and leave the membership fee out of it if you already pay it.
Skip it for a dinner of six, for a group with dietary needs you cannot cover, and for any event where the tray is one of many sides. In those cases a local deli tray, or a small order from a specialty sandwich shop, is simply the better buy.
