Buffets look simple. Make a lot of food, set one price, fill the pans.
But buffet profit lives in cost per guest, not in recipes. If you do not know that number, you are guessing your margin.
This guide shows the cost math, waste controls, and pricing rules that keep a buffet profitable in the U.S.
Quick Summary
- Buffet cost is cost per guest, not cost per item
- Overproduction buffer should be 5-8% for dinner
- Portion standards protect the buffet line
- Price tiers (lunch/dinner/kids) stabilize margin
- Reprice when meat and dairy move
Why Buffet Costing Is Tricky
- Overproduction is the silent tax.
- Guest consumption swings by daypart.
- Premium proteins move fast in price.
- Buffet pans encourage portion creep.
- To-go boxing hides extra cost.
Buffets win when you control volume, not just recipes.
The Core Buffet Formulas
Cost per guest = Total food cost / Expected guests
Food cost % = Cost per guest / Buffet price
Overproduction buffer = Planned food cost x Buffer %You are not pricing a plate. You are pricing a guest average.
Build the Cost per Guest (Simple Method)
Start with your base guest count for a daypart. Example: 120 dinner guests.
Now allocate cost by category:
| Category | Target per guest | Notes |
|---|---|---|
| Proteins | $5.50 | chicken, beef, seafood mix |
| Starches | $2.00 | rice, potatoes, pasta |
| Veg + salad | $1.50 | raw + cooked |
| Sauces + garnishes | $0.75 | dressings, toppings |
| Dessert | $1.25 | cookies, cakes, pudding |
| Total | $11.00 | base cost per guest |
Add a 6% buffer for overproduction:
$11.00 x 1.06 = $11.66 per guestIf your buffet price is $34.99:
Food cost % = 11.66 / 34.99 = 33.3%That is a healthy target.
Portion Standards That Protect Margin
Set simple standards for the line. Do not leave it to the pan.
| Item type | Portion standard | Why it matters |
|---|---|---|
| Protein | 4-5 oz | meat costs control the whole buffet |
| Starch | 5-6 oz | cheapest filler, stable margin |
| Veg | 3-4 oz | cost stable, adds variety |
| Salad | 3 oz | dressing cost can spike |
| Dessert | 2-3 oz | cheap, but easy to over-serve |
Train on ounces per serving, not “one scoop.”
Overproduction Buffer Rules
Buffet waste is real, but you can cap it.
- Lunch buffet: 3-5% buffer
- Dinner buffet: 5-8% buffer
- Weekend / holiday: 8-10% buffer
If you are above 10% every day, your pricing is wrong or your refill cadence is too aggressive.
Example: 120-Guest Dinner Buffet
Assumptions
- Planned guests: 120
- Base cost per guest: $11.00
- Buffer: 6%
Total food cost = 120 x 11.66 = $1,399Now estimate your total revenue:
- Buffet price: $34.99
- Guests: 120
Revenue = 120 x 34.99 = $4,199Food cost % = 1,399 / 4,199 = 33.3%
Now you can see if labor and rent fit.
Price Tiers That Actually Work
- Lunch price: 10-20% lower
- Dinner price: full menu, premium proteins
- Kids price: 40-60% of adult price
- Senior price: optional discount on off-peak days
Pricing tiers reduce waste from low-consuming guests while keeping margin from heavy eaters.
The Premium Protein Rule
Every premium protein has a price trigger.
Examples:
- Crab legs: limited nights or per-pound add-on
- Ribeye carving station: only on weekends
- Shrimp: cap by plate or replace with cheaper seafood
Do not let premium proteins live on the line all day.
To-Go Boxing (Hidden Cost)
If guests take food home, you must price it.
Options that work:
- Charge per box
- Limit boxing to late hours
- Offer a paid to-go package instead of free boxing
Free boxing can turn a 33% food cost into 40% overnight.
Market Signal (US)
BLS data shows food away from home prices up 4.1% (year-over-year, Dec 2025).
If your buffet price is fixed for a full year, that inflation cuts straight into margin.
