calculateweddingdrinks.com is a free onlinewedding alcohol calculator built to take the stress out of one of the trickiest parts of wedding planning: figuring out how much to drink to buy. We started this project after watching too many couples either run out of wine an hour into the reception or get stuck returning cases of untouched beer the next morning.
What we do
Our calculator turns a handful of simple details — your guest count, reception length, the share of guests who drink, and the kind of bar you're hosting — into an accurate, bottle-by-bottle shopping list in seconds. It rounds quantities up to real warehouse pack sizes, so it doubles as a Costco-ready shopping list you can print or copy straight to your phone.
Why we built it
Wedding planning is expensive and time-consuming enough without wrestling with spreadsheets and rules of thumb. We wanted a tool that is genuinely free, requires no sign-up, and gives you a trustworthy answer instantly — whether you're hosting an intimate dinner for 40 or a celebration for 300.
How our estimates work
Our figures are based on standard event-planning yields of roughly one drink per guest per hour, adjusted for drinker profiles and bar type. These are estimates intended to help you plan — actual consumption varies with your crowd, the season, and the time of day. We always recommend buying a small buffer and confirming your retailer's return policy on unopened bottles.
