Beer Party Calculator
Enter the drinking guests, party hours and the pace - two drinks per person per hour is the standard estimate. The calculator gives total drinks, the 24-bottle cases to buy, and the point where a keg finally beats cases.
The standard guest undercounts their own truth by one drink, and the ice never makes the shopping list: a pound per bottle is the cooler rule nobody budgets. The keg decision is real math - it wins somewhere past three cases, but only if the crowd actually finishes it, because a tapped keg goes flat within days.
How to use
- Count only the drinkers; seltzer guests are a separate line.
- Set the pace honestly - two an hour, not the aspirational one.
- Buy one case less than the total and one more bag of ice.
Frequently asked questions
How much beer do I need for a party?
Two drinks per person per hour is the hosting standard - ten people for four hours is about 80 drinks, or three and a half 24-bottle cases. The calculator prices it at your case rate.
When does a keg beat buying cases?
Somewhere past three cases - a half keg pours about 165 drinks at a lower per-drink price, but only if the party finishes it, because a tapped keg goes flat within days. Big crowds win; small gatherings lose.
How much ice do I need for a cooler of beer?
About one pound of ice per bottle, which is always more bags than anyone budgets. Two coolers help: one for drinking now, one sealed as the reserve that stays cold until the first melts.
Should the host drink for free?
The myth says yes; the friendship says buy back your own drinks. Hosts who skip the audit end the evening better - the calculator gives you the number to quietly cover yourself.
