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 labor day party modifier

× 1 (0% for spirits)

= 316 spirits servings needed

Labor Day Partys have standard spirits consumption.

Convert to bottles

316 servings ÷ 17 servings per bottle

= 18.6 bottles (raw)

Each bottle of spirits provides 17 servings.

Add 15% buffer & round up

18.6 × 1.15 = 21.4, rounded up

= 22 bottles

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.
