How We Calculated This

Our bartender-tested formula, step by step

Estimate actual drinkers

50 guests × 75% drinking rate

= 38 drinkers

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

Calculate base consumption

38 drinkers × 1.5 drinks/hour × 4 hours

= 228 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)

= 185 adjusted drinks

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

Apply halloween party modifier

× 1.3 (+30% for spirits)

= 238 spirits servings needed

Halloween Partys typically consume 30% more spirits than average.

Convert to bottles

238 servings ÷ 17 servings per bottle

= 14 bottles (raw)

Each bottle of spirits provides 17 servings.

Add 15% buffer & round up

14 × 1.15 = 16.1, rounded up

= 17 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.
