How much beer do I need for 150 guests?

You need 18 cases of beer for 150 guests at a corporate event. This provides 355 total servings with a 15% buffer to ensure you don't run out.

How much beer per person for a corporate event?

Plan for 2.4 servings of beer per person at a corporate event. This accounts for the fact that not everyone drinks alcohol and consumption naturally slows as the event progresses.

How many servings are in a case of beer?

One case of beer contains 24 servings. For 150 guests, you'll need 18 cases to provide 355 total servings.

What percentage of guests will drink beer at a corporate event?

At a corporate event with 150 guests, approximately 105 guests (70%) will actively drink. Our formula accounts for this when calculating the 18 cases you need.

Should I buy extra beer as a buffer?

Yes! Our calculation of 18 cases already includes a 15% buffer (3 extra cases). This ensures you won't run out even if some guests drink more than average. It's always better to have leftovers than to run short.

How long will 18 cases of beer last for 150 guests?

18 cases of beer will last approximately 3 hours for 150 guests at a corporate event. This calculation factors in the natural slowdown of consumption as the event progresses.

How We Calculated This

Our bartender-tested formula, step by step

Estimate actual drinkers

150 guests × 70% drinking rate

= 105 drinkers

At large events, about 70% of guests typically drink alcohol.

Calculate base consumption

105 drinkers × 1.5 drinks/hour × 3 hours

= 473 base drinks

Industry standard is 1.5 drinks per person per hour for a 3-hour event.

Apply consumption decay

Adjusted for drinking slowdown over time (decay factor: 2.65)

= 417 adjusted drinks

People drink faster in the first hour and slow down as the event progresses.

Apply corporate event modifier

× 0.85 (-15% for beer)

= 355 beer servings needed

Corporate Events typically consume 15% less beer than average.

Convert to cases

355 servings ÷ 24 servings per case

= 14.8 cases (raw)

Each case of beer provides 24 servings.

Add 15% buffer & round up

14.8 × 1.15 = 17.0, rounded up

= 18 cases

Always round up and add a buffer. Running out is worse than having leftovers!

* Why trust this formula?

Based on industry standards and refined by bartenders with 30+ years of experience. We factor in consumption decay (people drink less as events progress) and real-world drinking percentages.
