How to calculate party punch volume
Plan a beverage batch large enough for a party without relying on a vague per-person guess.
How the calculation works
Guests × servings × fluid ounces gives total ounces. A reserve percentage covers refills and spills before converting 128 ounces per U.S. gallon.
Example
Forty guests having 2.5 eight-ounce servings with 10% reserve require about 6.88 gallons.
Frequently asked questions
How much reserve should I use?
About 10% is a reasonable starting point; use more for long events or hot weather.
