Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 50 guests × 75% drinking rate | 38 drinkers |
| Calculate base consumption | 38 drinkers × 1.5 drinks/hour × 5 hours | 285 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 3.75) | 214 adjusted drinks |
| Apply New Year's Eve party modifier | × 0.8 (-20% for beer) | 169 beer servings if served alone |
| Share of the bar | 169 servings × 13% | 22 beer servings |
| Convert to cases | 22 servings ÷ 24 servings per case | 0.9 cases (raw) |
| Add 15% buffer & round up | 0.9 × 1.15 = 1.0, rounded up | 2 cases |
The Knot's wedding guide plans one drink per guest per hour with a 50/25/25 liquor, beer and wine split. This model counts only the guests who drink, slows the pace after the first hour, and keeps a 15 percent margin; read the methodology.

Beer at a New Year's Eve party
How much beer do I need for 50 guests?
You need 2 cases of beer for 50 guests at a New Year's Eve party, assuming you are serving a full bar. That is 22 servings with a 15% buffer. If beer is the only alcohol you serve, plan on 9 cases instead.
How much beer per person for a New Year's Eve party?
Plan for 0.4 servings of beer per person at a New Year's Eve party with a full bar. This accounts for the fact that not everyone drinks alcohol, that consumption slows as the event progresses, and that beer is only 13 percent of what gets poured.
How many servings are in a case of beer?
One case of beer contains 24 servings. For 50 guests, you'll need 2 cases to provide 22 total servings.
What percentage of the bar is beer at a New Year's Eve party?
About 13 percent of the drinks poured at a New Year's Eve party are beer. With 50 guests, roughly 38 will be drinking, and that share works out to 2 cases.
Should I buy extra beer as a buffer?
Our figure of 2 cases already includes a 15% buffer (1 extra cases). That covers guests who drink more than average. It is always better to have leftovers than to run short.
How long will 2 cases of beer last for 50 guests?
2 cases of beer will last approximately 5 hours for 50 guests at a New Year's Eve party, alongside the other drinks on the bar. This factors in the natural slowdown of consumption as the event progresses.
