Frequently Asked Questions

How much alcohol do I need for a party of 50 people?

For a 4-hour party with 50 guests, plan for about 200 drinks total. Using a standard mix, that is roughly 80 beers (7 cases), 15 bottles of wine, and enough liquor for 48 cocktails (2-3 bottles). Use our calculator for exact quantities based on your crowd.

What is the rule of thumb for party drinks?

The standard rule is 1 drink per guest per hour. Some planners use 2 drinks for the first hour, then 1 per hour after. For a 4-hour party, plan 4-5 drinks per person to be safe.

How do I split between beer, wine, and liquor?

A traditional split is one-third each. Modern events often skew toward 50% beer, 25% wine, 25% liquor for casual parties. Wine-focused crowds might prefer 50% wine, 25% beer, 25% liquor. Our calculator lets you choose your crowd profile.

Is this calculator only for parties or does it work for weddings too?

It works for any event. We started with weddings and expanded to all parties. The same math applies - the difference is in crowd preferences. Select your event type for tailored recommendations.

How much ice do I need for a party?

Plan for 1.5 pounds of ice per guest. For a 50-person party, that is about 75 pounds. Double this if you are chilling bottles in tubs rather than a refrigerator.
