Party Drink Calculator: Never Run Dry

Estimating drinks for a party means accounting for both how many guests you have and how long the party runs, since people drink more over a longer event. This calculator turns those two numbers into a shopping list.

The Formula

Total Drinks = Guests × Drinks per Hour × Party Hours, Cases Needed = ceil(Total Drinks / Drinks per Case)

Worked Example

20 guests, 1.5 drinks per hour each, over a 4-hour party.

Total Drinks = 20 × 1.5 × 4 = 120, Cases Needed = ceil(120/12) = 10 cases

How to Use This Calculator

  1. Enter the number of guests.
  2. Enter the expected drinks per person per hour.
  3. Enter the party duration in hours.
  4. Optionally adjust drinks per case (12 is standard).
  5. Click Calculate to get total drinks and cases needed.
