Calculate how much beer, wine, liquor, mixers, and non-alcoholic drinks you need for any party. Covers cocktail parties, casual BBQs, weddings, and more.
Running out of drinks at a party is a hosting nightmare. Buying too much wastes money. This Party Drink Calculator tells you exactly how much beer, wine, liquor, and mixers to buy for any size event.
The standard rule of thumb is 2 drinks per person for the first hour and 1 drink per person for each additional hour. But that varies by event type — a cocktail party has higher consumption than a dinner party. A summer BBQ runs through more beer than a winter gathering. This calculator adjusts for event type, duration, and the mix of drinkers.
Enter your guest count, party duration, and the mix of beer/wine/cocktail drinkers. The calculator outputs exact quantities: cases of beer, bottles of wine, handles of liquor, and liters of mixers. It also handles non-alcoholic beverages, ice requirements, and gives a total cost estimate. Perfect for everything from backyard gatherings to wedding receptions.
Beverage planning for events is notoriously difficult to estimate. Too little and guests are disappointed. Too much and you waste money. This calculator gets it right. Keep these notes focused on your operational context. Tie the context to the calculator’s intended domain. Use this clarification to avoid ambiguous interpretation. Align this note with review checkpoints.
Drinks per person = 2 (first hour) + 1 per additional hour. Standard drink: 12 oz beer, 5 oz wine, 1.5 oz liquor. Beer: 1 case = 24 beers. Wine: 1 bottle = 5 glasses. Liquor: 1 handle (1.75L) = ~39 shots. Ice: 1 lb per person.
Result: 200 drinks total: 60 beers (2.5 cases), 50 wine glasses (10 bottles), 90 cocktails (4 bottles liquor)
40 guests × 5 drinks each (2 first hour + 3 more) = 200 total drinks. Split by preference: 30% beer, 25% wine, 45% cocktails. Plus 40 lbs ice and 20L mixers.
Cocktail parties (standing, socializing) = highest consumption, about 2.5 drinks/hour after the first hour. Dinner parties = moderate, about 0.75 drinks/hour during dinner. BBQs and outdoor events = high for beer, moderate overall. Weddings = follow the cocktail party model for cocktail hour, dinner party model during reception dinner.
For a full bar: tonic water, club soda, cola, ginger ale, cranberry juice, orange juice, lemon/lime juice. Plan 1 liter of mixer per 3 cocktail drinks. Garnishes: 1 lime per 8 drinks, 1 lemon per 10 drinks. Don't forget cocktail napkins — plan 3 per guest.
Costco and Sam's Club offer the best prices on alcohol in bulk. Buy house wine by the case for 10–15% discount. Opt for mid-range spirits — most people can't tell the difference in mixed drinks. Keg beer is 40–50% cheaper per serving than bottles if you have 30+ beer drinkers.
2 drinks for the first hour, 1 per hour after that. A 4-hour party = 5 drinks per person average. Adjust up for cocktail parties, down for daytime events.
General guideline: 40% beer, 30% wine, 20% cocktails, 10% non-alcoholic. Adjust for your crowd — a summer BBQ skews more beer, a formal dinner more wine.
About 1 pound per person for drinks, plus extra for coolers. For a 40-person party, get 40–60 lbs of ice.
If everyone drinks wine: 20 people × 5 drinks ÷ 5 glasses/bottle = 20 bottles. If only 30% are wine drinkers: about 6 bottles.
Yes! A signature cocktail simplifies bar setup and shopping. It also reduces variety needed. Batch it in a large dispenser for self-service.
Plan 2–3 non-alcoholic options. Sparkling water, flavored lemonade, and mocktails are crowd-pleasers. Budget 3–4 drinks per non-drinker.
