How We Calculated This

Our bartender-tested formula, step by step

Estimate actual drinkers

300 guests × 65% drinking rate

= 195 drinkers

At xlarge events, about 65% of guests typically drink alcohol.

Calculate base consumption

195 drinkers × 1.5 drinks/hour × 4 hours

= 1170 base drinks

Industry standard is 1.5 drinks per person per hour for a 4-hour event.

Apply consumption decay

Adjusted for drinking slowdown over time (decay factor: 3.25)

= 951 adjusted drinks

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

Apply thanksgiving modifier

× 0.8 (-20% for beer)

= 761 beer servings needed

Thanksgivings typically consume 20% less beer than average.

Convert to cases

761 servings ÷ 24 servings per case

= 31.7 cases (raw)

Each case of beer provides 24 servings.

Add 15% buffer & round up

31.7 × 1.15 = 36.5, rounded up

= 37 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.
