What does an open bar cost per person, and how many drinks does a guest actually have?

The bar is the second-largest line on most reception bills and the one priced with the least information. Every calculator on the internet asks for your guest count and your hours, multiplies by the same number, and calls the result a plan. This is where that number came from.

Two ways to be billed

A package bar charges a flat price per person for a set number of hours and a tier of brands; a consumption bar counts what was poured and bills it after.¹ One marketplace's 2026 figures put an open bar at "$15-$90 per person depending on your location, drink selection, and service style," with bar services averaging $5,541 nationally and most couples spending $4,400 to $6,600, about 11 percent of the budget.¹ Those are asking prices reported by vendors and budgets reported by couples, not a measured cost, and the same source shows the identical package running roughly three times as much in New York as in Milwaukee.¹

A real package looks like this. The author's own 2026 Florida hotel order bundled the bar into the meal price: a "Premium Bar - One Hour" during cocktails and a "Premium Bar - Three Hours" through dinner and dancing, each listing the well spirits, five wines and eight beers by name, with the line "Shots are not permitted" and the bar closed for the half hour of introductions and first dances.² Four hours of open bar, paid for every adult in the room whether they drank six or none, plus plus.² That is what a package is: certainty for you, and for the venue a bet that the room averages out.

Where "two the first hour, then one an hour" comes from

Every calculator uses it. The marketplace states it as "the standard consumption model": "about two drinks in the first hour, then one drink per hour after that for each guest."¹ Its own alcohol calculator softens it to "the typical school of thought is to plan one drink per hour per guest," and cites nothing.³ No study of wedding guests is behind it. What is behind it is a health rule that has nothing to do with buying: a standard drink in the United States is 14 grams of alcohol, the amount in a 12-ounce beer, a 5-ounce glass of wine or a 1.5-ounce shot,⁴ and "one rule of thumb is that the liver can process 1 standard drink per hour," a rule the university health service quoting it immediately qualifies as "may or may not apply to you."⁵ Somewhere the rate at which a body clears a drink became the rate at which a guest orders one. It is a plausible average, and it is the ceiling of what is actually known.

What the count buys you, and what it does not

On a package bar the count buys you nothing; you pay per head for the hours. On a consumption bar it is the whole bill, so the rule of thumb is your budget's only anchor. Five hours at two-then-one is six drinks a guest; a hundred adults is six hundred pours. Whether your crowd is a six-hundred-pour crowd is something you know and the calculator does not. A daytime wedding, an older room, a long drive home, a dry side of the family: each one moves the number, and only the consumption model lets the number move your bill.

Two more lines to read. The people pouring earned a national median of $16.51 an hour in May 2025, tips included.⁶ And in Florida, "corkage fees, setup fees, or similar charges" on the bar bill are taxed along with the drinks, so a bartender fee carries both pluses.⁷

Why your mother cares

She remembers a cash bar, or a hall where the beer came in a keg and the price of the room included it. She will ask why the bar is a third of the food bill. The honest answer is that the industry stopped counting drinks and started counting hours, and a package bar charges the same for your aunt's one glass of white as for your college roommate's evening. If the family is light drinkers, tell the venue you want consumption pricing and a cap, and let the room prove it.
