Planning how many drinks to provide for a party of 150 or more can cause stress, but only if you let it. Here's a simple way to easily calculate the amount you'll need.

Skill level:


    Do your math

  1. 1

    Determine the overall number of drinks by multiplying the number of people attending the event by four. That means you need 600 total drinks for a party with 150 people. Most people drink about three drinks at a party. If you think your guests will drink more than that multiply by five or more.

  2. 2

    Determine how many different kinds of drinks will be served.

  3. 3

    Define the amount of a single drink for each type of drink that will be served. For example, a bottle of beer provides one drink, a 750ml bottle of wine provides about five drinks, and a 750ml bottle of hard alcohol is about 17 drinks.

  4. 4

    Estimate the percentage of people that will want to enjoy each type of drink. For example, if you will serve beer, wine and hard alcohol, a common formula assumes that 50 per cent of the people will want beer, 25 per cent will want wine and 25 per cent will want hard alcohol.

  5. 5

    Check your math against a free online party planner.
