How We Calculated This

Our bartender-tested formula, step by step

1

Estimate actual drinkers

200 guests × 65% drinking rate
= 130 drinkers

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

2

Calculate base consumption

130 drinkers × 1.5 drinks/hour × 4 hours
= 780 base drinks

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

3

Apply consumption decay

Adjusted for drinking slowdown over time (decay factor: 3.25)
= 634 adjusted drinks

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

4

Apply birthday party modifier

× 1.2 (+20% for spirits)
= 761 spirits servings needed

Birthday Partys typically consume 20% more spirits than average.

5

Convert to bottles

761 servings ÷ 17 servings per bottle
= 44.8 bottles (raw)

Each bottle of spirits provides 17 servings.

6

Add 15% buffer & round up

44.8 × 1.15 = 51.5, rounded up
= 52 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.

Pro Tips for Your Birthday Party

Insider advice from experienced bartenders

💡

Milestone birthdays (21st, 30th, 40th, 50th) consume 25% more than regular birthdays.

⏰

Birthday parties have 3x more shots than any other event type - stock shooters.

🎯

Consumption drops 60% during cake and presents - factor in 30-45 min of low drinking.

🧊

Know your crowd's age - 21-30 year olds drink 30% more beer, 50+ drink 35% more wine.

✨

Consider a signature 'birthday cocktail' to make the guest of honor feel special.

🛒 Buying Guide

Birthday parties vary wildly by age group. For 21-35, stock up on beer and mixers for cocktails. For 40+, increase your wine selection. Always have extra for milestone birthdays - people celebrate harder at 30, 40, and 50.
