Wedding Food Calculator
Enter your guest count and service style and you'll get an exact shopping list: cocktail hour pieces, protein by the pound, sides, non-alcoholic drinks, and how many servers to hire.
Plan on 8 ounces of cooked protein per adult, plus a service-style buffer. For a 150-guest buffet, that's about 118 pounds of raw protein, 42 pounds of starch, and 335 water bottles.

The Wedding Money Kit's DIY Wedding Food Calculator saves this shopping list for your headcount, adds a column for what you actually pay, and sets your grocery total next to what a caterer would charge for the same crowd.

The per-guest rule, and why buffets need more
Wedding caterers plan around 8 ounces of cooked protein per adult at a buffet, split evenly if you're serving two proteins, plus 4 ounces each of starch and vegetable and 3 ounces of salad (WebstaurantStore, Summer & Cinnamon). But a buffet needs more food than a plated dinner serving the same portions, because self-service is uneven. Some guests take seconds, some skip a dish entirely, and a nearly empty tray still has to look presentable for the last table through the line. That's why the calculator adds a 10 percent buffer on top of the straight per-adult math for a buffet, and 15 percent for family-style, where a shared platter has to stay full at every table it's passed to.
Plated dinners get none of that buffer. The kitchen portions every plate in the back, so there's no self-serve waste to plan around, and this calculator hands you a flat per-plate card instead of scaling quantities by guest count at all.
Heavy appetizers as the meal
Some receptions skip the sit-down meal entirely and run on a heavy hors d'oeuvres spread instead. The math changes completely: instead of one plate per guest, you're pricing a running schedule of passed and stationed bites across the whole reception. Plan on 15 pieces per guest across the first two hours, then 4 more per guest for every hour after that (Here Comes The Guide). A typical 5-hour reception puts guests at 27 pieces each by the end, which is enough variety and volume to function as dinner. Pick "Heavy appetizers" as your service style above and the calculator prices the whole night off that schedule and drops the main-meal rows.
A worked example: 150 guests, buffet, two proteins
Say you've got 150 guests at a buffet with a 1-hour cocktail hour and two proteins. The cocktail hour alone needs 900 pieces across 7 varieties, about 129 of each. For the main meal, each of the two proteins comes to 42 pounds cooked, which means buying 59 pounds raw per protein once you account for cooking loss. Add 42 pounds of starch, 42 pounds of vegetable, 31 pounds of salad, and 248 rolls. On the drinks side, that's 335 water bottles, 210 cans of soda, and 25 gallons of lemonade or iced tea. Staff it with 7 servers and budget a $140-$350 tip. Change any input above and the whole list rebuilds instantly.
How much food by guest count
Here's the buffet shopping list at six common guest counts, all with a 1-hour cocktail hour, two proteins, and the 10 percent buffer already built in:
| Guests | Raw protein | Starch | Water bottles | Servers |
|---|---|---|---|---|
| 50 | 40 lbs | 14 lbs | 112 | 3 |
| 100 | 78 lbs | 28 lbs | 224 | 5 |
| 150 | 118 lbs | 42 lbs | 335 | 7 |
| 200 | 156 lbs | 56 lbs | 446 | 10 |
| 250 | 192 lbs | 69 lbs | 558 | 12 |
| 300 | 232 lbs | 83 lbs | 670 | 14 |
These use the buffet default with two proteins and a 1-hour cocktail hour. Switch to family-style, plated, or heavy appetizers, or change the hours and protein count, and every row moves. Run your own numbers in the calculator above, or open the dedicated 100, 150, or 200 guest pages for the full bottle-by-bottle breakdown at that size.
Kids and vendor meals
Kids rarely eat a full adult portion, so this calculator counts each child as half a guest for main-meal math, a standard catering-industry shortcut (Summer & Cinnamon). Vendor meals work the other way: your photographer, DJ, band, and planner are working a long day and typically eat a full adult plate off the same buffet or kitchen line, so each vendor meal adds a full portion. Enter both numbers separately above, since they pull the main-meal quantities in opposite directions.
The drinks nobody budgets for
Alcohol gets planned first, but water, soda, lemonade or iced tea, and coffee are just as real a cost, and they're easy to forget until the reception is short on cups. This calculator splits non-alcoholic drinks 40 percent water, 25 percent soda, and 35 percent lemonade or iced tea, sized off how many guests drink alcohol and how many don't (Gallup), plus a coffee row for the roughly 85 percent of adults who take a cup, 30 percent of those decaf. One thing this tool deliberately skips: ice. Ice serves both the bar and the non-alcoholic drinks, so it's sized once, on the wedding alcohol calculator, to keep you from buying it twice.
Staffing and tips
Server counts come straight from the same staffing ratios as our catering cost calculator: about one server per 22 guests for a buffet, family-style, or heavy-appetizer reception, and one per 11 for a plated dinner, since plated service takes more hands per table. The tip range follows the same per-server band. If your caterer's quote already includes a service charge, the catering service charge calculator tells you whether that charge already covers the tip or whether staff still need one separately.
Frequently Asked Questions
How much food do I need for a wedding buffet?
Plan on 8 ounces of cooked protein per adult, 4 ounces each of starch and vegetable, 3 ounces of salad, and about one and a half rolls, then add a 10 percent buffet buffer. For 150 guests that works out to roughly 118 pounds of raw protein to buy, 42 pounds of starch, and 248 rolls. Enter your own guest count above for the exact list.
How much more food does a buffet need than a plated dinner?
A buffet needs a 10 percent overage on every dish because guests serve themselves unevenly and a tray can't run out mid-line. Family-style needs 15 percent, since a shared platter has to stay full down to the last table. A plated dinner needs no overage at all: the kitchen portions each plate exactly, so nothing gets built in for waste. That's also why this calculator skips main-meal quantities for plated and hands you a per-plate card instead; the caterer counts the rest.
Can heavy appetizers replace a sit-down meal?
Yes, and a lot of cocktail-style receptions do it. Instead of a plated or buffet dinner, you serve 15 pieces per guest across the first two hours and 4 more per guest for every hour after that. For a typical 5-to-6-hour reception, that puts guests well past 20 pieces each, which is enough to function as dinner. Pick heavy appetizers as your service style above and the calculator drops the main-meal rows and prices the whole reception off that schedule instead.
How much food do I need for 150 wedding guests?
For a 150-guest buffet with a 1-hour cocktail hour and two proteins, plan on about 118 pounds of raw protein, 42 pounds of starch, 42 pounds of vegetable, 248 rolls, and 900 cocktail hour pieces. See our dedicated 150-guest page for the full breakdown with both one- and two-protein lists.
Do kids and vendor meals count the same as adult guests?
No. Kids count as half an adult portion in this calculator, since a child's plate rarely matches an adult's appetite. Vendor meals, on the other hand, are added at a full adult portion, because your photographer, DJ, and planner eat a full plate off the same line. Enter both separately above and the main-meal quantities adjust for you.
What drinks does this calculator cover that the bar calculator doesn't?
This tool sizes the non-alcoholic drinks: water, soda, lemonade or iced tea, and coffee with a decaf split. It does not touch beer, wine, or liquor, and it does not count ice, since ice serves both bars, and double-counting it here would mean buying too much. Use the wedding alcohol calculator for the bar and its ice, and this one for everything else guests drink.
