How We Calculated This

Our bartender-tested formula, step by step

Estimate actual drinkers

75 guests × 75% drinking rate

= 56 drinkers

At medium events, about 75% of guests typically drink alcohol.

Calculate base consumption

56 drinkers × 1.5 drinks/hour × 5 hours

= 420 base drinks

Industry standard is 1.5 drinks per person per hour for a 5-hour event.

Apply consumption decay

Adjusted for drinking slowdown over time (decay factor: 3.75)

= 315 adjusted drinks

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

Apply 4th of july party modifier

× 1.4 (+40% for beer)

= 443 beer servings needed

4th of July Partys typically consume 40% more beer than average.

Convert to cases

443 servings ÷ 24 servings per case

= 18.5 cases (raw)

Each case of beer provides 24 servings.

Add 15% buffer & round up

18.5 × 1.15 = 21.3, rounded up

= 22 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.
