Party Bar Math

About Roger

Roger Maxwell is a Brooklyn-based head bartender and events pro. He has worked busy New York City bars and events, where running out of ice or wine halfway through the night isn't an option.

His day-to-day is building cocktail menus, working out cost per pour and training bar staff. These calculators follow the way he plans a bar, so your party bar comes out right.

Drink responsibly

Please drink responsibly. In the US you must be 21 or older to drink alcohol. Plan rides home before the party starts, and don't drink and drive. Always offer good non-alcoholic options and plenty of water. The calculators estimate what to buy, not how much anyone should drink.
