Punch Batch Calculator

Parts are relative amounts, not fixed units. A 2:1:1 recipe means twice as much of the first ingredient as each of the others. Parts let one recipe scale to any batch size while keeping the same balance.

Set the total servings and serving size, then list each ingredient's parts. The calculator finds the batch volume and splits it by parts, so the ingredient ounces always add up to the full batch.

Punch servings are often 4 to 6 oz, smaller than a full cocktail because guests refill from a bowl. Use 4 oz for a punch cup or up to 8 oz for a tall glass with ice.

If the recipe is stirred or shaken when made single, add a dilution part such as water for the chill. For a punch served over a large ice block, the melt happens in the bowl, so many recipes skip extra water.

The math is the same in any single unit. Treat the serving size as your unit of choice and the ingredient amounts will come out in that same unit, since it only splits the total by parts.
