Formula and assumptions
- Total drinks =
guests × hours × drinks/hour. - Open-bar mode applies a planning multiplier to account for generally higher service volume.
- Beer conversion uses 12 oz servings and 24 bottles per case.
- Wine conversion uses 5 glasses per 750 mL bottle as a common planning baseline.
- Liquor conversion uses a 1.5 oz shot equivalent for bottle calculations.

FAQ
How should I choose drinks per hour?
Start conservatively and adjust based on event type, food availability, weather, and the proportion of nonalcoholic options.
Why does the split normalize automatically?
If your split entries do not total 100%, the calculator proportionally normalizes them so the distribution remains valid.
Can I use this for weddings?
Yes. This page is designed to support wedding and reception planning without creating separate thin pages for every guest count.
