Why buffets need their own worksheet
On a regular menu you can cost a plate and be fairly confident each guest gets one. A buffet doesn't work that way. One guest has a salad and soup, the next goes back for prime rib three times. What you can measure is the total food you put out in a service and the number of people who ate. Divide one by the other and you have an average cost per guest, which is the number your price has to cover.
The formula
- Total food cost is the cost of everything that went out to the line, the salad bar and the dessert station for one service, at your purchase prices.
- Cost per guest is total food cost divided by guests served.
- Adjusted cost per guest adds a waste and refill allowance for food that was discarded or replenished but isn't in your totals.
- Price at target is adjusted cost divided by your target food cost percentage.
The calculator also rounds up to the next price ending in .99 and shows the food cost percentage at your current price.
How to fill in the worksheet
- Pick a single service: Tuesday lunch, Friday dinner or Sunday brunch. Weekday and weekend buffets often have very different guest counts and line-ups, so price them separately.
- List each station or item and the food cost that went out. The easiest way is to cost each pan from its recipe card and count pans. Some kitchens weigh each pan before it goes out instead.
- Enter the number of guests who paid for the buffet. Use your POS count, not a guess.
- Add your waste allowance. If you're already counting every refill pan, the allowance covers only what you threw away and didn't record.
- Enter your target food cost and, if you have one, the current price.
- Download the CSV after each service. After a few weeks you'll have an average that's far more reliable than any single day.
A worked example
A weekday lunch buffet puts out $412 of hot-line food, $138 on the salad bar and $74 of bread and desserts, for $624 in total. It served 160 guests, so food cost per guest is $3.90. Adding an 8 percent waste allowance brings it to about $4.21.
At a 32 percent target, the price needs to be about $13.16, which rounds to $13.99. The current price of $14.99 puts food cost near 28 percent, so this lunch is on target with room to spare. If guest count dropped to 120 on the same food, cost per guest would jump to $5.20 before waste, and the same price would run well over target. That's the real lesson of the worksheet: on a buffet, guest count and production planning move food cost as much as purchase prices do.
Controlling buffet cost after you set the price
Production planning comes first. Use your guest counts to forecast each service, and cook in batches tied to that forecast. Keep a simple log of pans sent and pans returned; a week of logs will show you which items are overproduced.
Line design is next. Guests fill their plates with what they see first. Put salads, breads, rice and vegetable dishes ahead of the expensive proteins, and use pans and serving spoons sized for the portion you want.
Finally, plan the last hour. A buffet that stays fully stocked until close throws away the most food. Switch to half pans, offer a cooked-to-order item, or close stations one at a time, and tell guests politely what's coming out fresh.

Frequently asked questions
How do you price a buffet per person?
Add up the food cost of everything you put out for one service, divide by the number of guests who ate, add an allowance for waste and refills, then divide by your target food cost percentage. Track several services, because one slow day or one busy holiday will skew a single reading.
What waste allowance should I use for a buffet?
Measure it. Weigh or count what comes off the line and goes in the trash for a week or two, and compare it with what you put out. Until you have your own number, a conservative allowance in the high single digits is a reasonable placeholder for a well-run line, and much higher for a line that is kept full right up to closing.
Should a buffet run a higher food cost than the regular menu?
Often it does. Buffets usually need less service labor per guest, so many operators accept a higher food cost percentage in exchange for lower labor. Look at the buffet's prime cost, food plus the labor it needs, before deciding that a higher food cost is a problem.
How can I lower buffet food cost without guests noticing?
Put the lower-cost, high-appeal items first in the line, use smaller serving utensils and pans for the expensive items, refill in smaller batches near the end of service, and have a chef carve or serve the most expensive protein instead of leaving it self-serve.
Should children pay a lower price?
Most buffets use a child price or price by age bracket. Count children separately in your guest tally for a few weeks so you can see how much they really eat, then set the child price from that data.
