Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 150 guests × 70% drinking rate | 105 drinkers |
| Calculate base consumption | 105 drinkers × 1.5 drinks/hour × 3 hours | 473 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 2.65) | 417 adjusted drinks |
| Apply corporate event modifier | × 0.85 (-15% for beer) | 355 beer servings if served alone |
| Share of the bar | 355 servings × 26.1% | 93 beer servings |
| Convert to cases | 93 servings ÷ 24 servings per case | 3.9 cases (raw) |
| Add 15% buffer & round up | 3.9 × 1.15 = 4.5, rounded up | 5 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 corporate event
How much beer do I need for 150 guests?
You need 5 cases of beer for 150 guests at a corporate event, assuming you are serving a full bar. That is 93 servings with a 15% buffer. If beer is the only alcohol you serve, plan on 18 cases instead.
How much beer per person for a corporate event?
Plan for 0.6 servings of beer per person at a corporate event 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 26.1 percent of what gets poured.
How many servings are in a case of beer?
One case of beer contains 24 servings. For 150 guests, you'll need 5 cases to provide 93 total servings.
What percentage of the bar is beer at a corporate event?
About 26.1 percent of the drinks poured at a corporate event are beer. With 150 guests, roughly 105 will be drinking, and that share works out to 5 cases.
Should I buy extra beer as a buffer?
Our figure of 5 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 5 cases of beer last for 150 guests?
5 cases of beer will last approximately 3 hours for 150 guests at a corporate event, alongside the other drinks on the bar. This factors in the natural slowdown of consumption as the event progresses.
