About
One of the most stressful parts of event planning is ordering alcohol. Buy too little, and the party ends early; buy too much, and you waste budget on bottles you can't return. This Wedding & Event Alcohol Calculator solves that dilemma using industry-standard catering formulas.
This tool calculates the total number of standard drinks required based on guest count, duration, and crowd habits. It then breaks this data down into a shopping list of bottles and cases, allowing you to walk into a liquor store with confidence. Whether it's a beer-heavy BBQ or a wine-centric wedding reception, customize the split to match your specific needs.
Formulas
The core calculation relies on the "One Drink Per Person Per Hour" rule, adjusted for duration decay.
Standard Event Assumption: 2 drinks for the first hour, 1 drink for each hour after.
