Non-Alcoholic Drinks Calculator
Soda, juice, punch, water and mocktail supplies for a dry event — worked out by guest count and hours, in the bottles, cartons and packs the shop actually sells.
Dry events run through more drinks than people plan for. Nobody nurses a single glass for an hour, so consumption sits near one serving per adult per hour and higher for children. The most common mistake isn't variety — it's simply running out. Buy for the full run time, not the first hour.
Counted at 1.2 servings an hour — more often, smaller amounts.

How Much to Buy
The planning rate is one 8 oz serving per adult per hour, and 1.2 for children. Kids come back to the table more often in smaller amounts, and a dry event runs faster than people expect — there's no slow sipping, so the table empties steadily.
- Total servings = adults × hours + kids × 1.2 × hours. Everything else is a split of that number.
- Convert to packaging, not ounces. A 2 L bottle is 8.5 servings, a 64 oz carton is 8, a gallon of punch is 16.
- Water is a third of it. Genuinely — people drink far more water at a dry event than at one with a bar, and it's the cheapest thing on the list.
- Two cups per guest. People put a cup down, lose it, take another. Caterers just plan for it.
The formulas
Servings = adults × hours + kids × 1.2 × hours
2 L bottles = ceil(servings ÷ 8.45) · Punch gallons = servings ÷ 16
Worked example — 30 adults, 10 kids, 3 hours: 126 servings → about 6 × 2 L of soda, 4 juice cartons, 38 bottles of water, 0.8 gallons of punch, 60 lb of ice and 80 cups.
Running a Mocktail Bar
Per drink, plan about 4 oz of mixer (club soda, tonic, ginger ale), 1 oz of syrup or cordial, and a garnish. That means a 750 ml syrup bottle makes roughly 25 drinks and a 2 L mixer makes about 17.
Two or three combinations beat a dozen. A long menu slows the queue, confuses people who just want something nice in a glass, and leaves you with half-used bottles. Pick a citrus one, a sweet one, and something with ginger — that covers most preferences.
Serve them in real glassware with a proper garnish. The difference between a mocktail and a soft drink is almost entirely presentation, and it matters to guests who aren't drinking.

Getting It Right
- Buy ice first and buy more. 1.5 lb per guest. A mocktail bar uses more, because every drink is built over ice.
- Cans beat bottles for standing events. Nothing goes flat, nothing needs a cup, and the leftovers keep.
- Chill overnight. Warm soda over ice is watery within minutes. Fridge space or a cooler on the porch.
- Label the punch. If there are two bowls, people will ask about every single one unless there's a card.
- Name the cups. A marker by the drinks table roughly halves how many cups you go through.
- Put water everywhere, not just at the drinks table. It's the cheapest item and the one people actually run out of.
