Frequently Asked Questions

The golden rule is 1.5 drinks per person per hour. For a party of 20 people lasting 3 hours, that's roughly 90 total drinks. This calculator breaks that down by drink type based on your guest mix of drinkers vs. non-drinkers, the party vibe, and even the season. Always round up — it's better to have a few extras than run out!

There's a popular 50-30-20 rule: 50% beer, 30% wine, 20% liquor. However, this varies heavily by party type. A Super Bowl party might be 60% beer, while a cocktail party flips to 65% liquor. Our calculator adjusts these ratios automatically based on your selected party type for more accurate results.

Plan for 1 to 1.5 pounds of ice per person for a standard party. In summer or for outdoor events, bump that up to 2 pounds per person. Ice is used for chilling drinks, filling coolers, and serving cocktails. A 20-person party typically needs 20–30 lbs of ice. Buy more than you think — it's inexpensive and leftover ice can always be used later.

Yes, absolutely. In hot summer weather, people drink approximately 20–30% more fluids. You'll want extra water, soda, and beer. For winter indoor parties, consumption tends to be more moderate, though warm cocktails and red wine become more popular. Our calculator includes a season selector that adjusts totals automatically.

Non-drinkers typically consume 1–2 soft drinks per hour. Also remember that drinkers will want some non-alcoholic options too — as mixers or just to pace themselves. A good rule of thumb: provide at least 1 soft drink per person per hour, then add extra for mixers. Offering a variety (cola, lemon-lime soda, sparkling water, juice) keeps everyone happy.

Plan for 2–3 cups per person for the entire party. People switch drinks, lose track of their cup, or need fresh ones for different beverages. For a 20-person party, having 50–60 cups on hand is smart. If you're serving both hot and cold drinks, or using disposable cups, add 15% extra just in case.

Wine (750ml): ~5 glasses (5oz pours). Liquor (750ml): ~17 servings (1.5oz shots or cocktail bases). Beer: 1 bottle/can = 1 serving (12oz). Knowing these conversions helps when shopping. For example, if you need 30 wine servings, buy at least 6 bottles. Our calculator shows both servings and bottle counts for easy shopping.

Essential mixers: club soda, tonic water, cola, ginger ale, cranberry juice, orange juice, and simple syrup. Also stock fresh lemons, limes, and bitters. A good rule: count mixers as part of your soft drink total. For every bottle of liquor, plan on 3–4 liters of mixers. Our soft drink calculation already factors in mixer needs for cocktail-heavy parties.

Unopened beer, wine, and liquor keep for months (or years for liquor). Unopened soda lasts 6–9 months past its date. Leftover ice can go back in the freezer. Consider sending guests home with a drink or two as a fun party favor! Most hosts agree: having 10–15% leftovers is far better than running out mid-party. Err on the side of abundance.

This calculator uses industry-standard event planning formulas based on 1.5 drinks per person per hour, adjusted for drinker ratio, party type, season, and intensity. It's trusted by party planners and caterers as a reliable baseline. Every party is unique — adjust up if your crowd are enthusiastic drinkers, or down for a more relaxed gathering. We recommend adding a 10% buffer to all results for peace of mind.
