Set the alcohol share
Lower it for a daytime or family event and add soft drinks accordingly.
What does this tool do?
Drink planning follows a simple rule: about two drinks in the first hour and one per hour after that. This calculator scales the rule to the guest list, adjusts for the pace of the party and splits the total between alcoholic and non-alcoholic options.
The Formula
Drinks = guests × (hours + 1) × pace factor; alcoholic = total × alcohol share; ice = 1 lb per guestFrequently Asked Questions
How many drinks per person should I buy?
Plan on two drinks in the first hour and one per hour after that. The pace selector adjusts this baseline for a quiet gathering or a lively crowd.
How much ice do I need?
Roughly one pound of ice per guest for drinks and coolers. Add extra for an outdoor party in warm weather or for chilling bottles.
