Event Drink Calculator

Formula

To calculate the number of drinks needed (D):

\[ D = A \times T \times 1.25 \]

Where:

\(D\) is the number of drinks
\(A\) is the number of adults at the event
\(T\) is the total time of the event (hours)

What is the Average Amount of Drinks a Person Has at an Event?

The average person will consume about one and a quarter drinks per hour at an event that has an open bar. Some may drink much more than this, and some may drink less, but 1.25 drinks per hour is accurate on average. For events where the bar is not open, the drinks per hour decreases as people watch their spending.

Example Calculation

Let's assume the following values:

Number of Adults (A) = 50
Total Event Time (T) = 4 hours

Using the formula:

\[ D = 50 \times 4 \times 1.25 = 250 \text{ drinks} \]

The number of drinks needed is 250 drinks.
