BYOB Wedding Alcohol Calculator — frequently asked questions
How does this wedding alcohol calculator work?+
It starts with a common wedding-bar rule of thumb: two drinks per drinking guest for the first hour and one drink per hour after that. It then adjusts for season, buffer, and drink mix before converting servings into beer cases, wine bottles, liquor bottles, champagne, mixers, ice, and cost.
How much alcohol should I buy for a BYOB wedding?+
The right amount depends on guest count, reception length, weather, venue temperature, and whether your crowd prefers beer, wine, cocktails, or champagne. This calculator turns those assumptions into a practical shopping estimate you can review with your venue or bartender.
Can I customize the beer, wine, liquor, and champagne split?+
Yes. The free calculator includes preset drink mixes. Pro unlocks a custom mix plus sober-guest percentage, safety buffer, editable costs, and a copyable shopping list.
Is my wedding information sent to a server?+
No. Guest count, hours, drink mix, cost assumptions, and shopping estimates are calculated entirely in your browser.
