The Quick Answer on Event Bar Pricing
Bar service for a catered event usually costs $15 to $45 per guest. Beer and wine sits at the low end. A full open bar with premium spirits sits at the top.
That number covers more than liquor. A real bar package buys licensed bartenders, setup and breakdown, ice, glassware, mixers, and garnish. Evolved Catering builds bar service catering around your guest count and event length, so the quote reflects your night instead of a generic head count.
Here is how the tiers break down, what the staffing actually costs, and the four questions that stop a surprise bill.
What Does Bar Service Cost Per Person?
Most bar packages price per guest for a three to four hour event. The tier you pick matters more than the brand of gin.
Beer and wine only: $15 to $20 per guest
Two or three beers, a red, a white, and a sparkling option. This is the right call for daytime events, showers, and corporate lunches where nobody expects a cocktail list.
Beer, wine, and signature cocktails: $20 to $30 per guest
Add two or three house cocktails built around the couple, the season, or the company. It reads custom without the cost of stocking a full back bar.
Full open bar with premium spirits: $35 to $45 per guest
Top-shelf pours, a full cocktail list, and enough staff to keep the line short all night. Galas, large receptions, and milestone weddings usually land here.
Longer events push every tier higher. A five-hour reception is not a four-hour reception with an extra hour of pouring, it is an extra hour of staffing, ice, and product for every guest in the room.
What You Are Actually Paying For
A bar quote is four costs bundled into one per-guest number. Pull them apart and the price stops feeling arbitrary.
Product
The beer, wine, spirits, and mixers themselves. Guests average two to three drinks in the first hour, then roughly one per hour after that. Any bar plan that ignores the front-loaded first hour runs dry early.
Staffing
The working standard is one bartender per 50 guests, plus a bar back once you pass about 100. Understaffing does not save money, it just moves the cost onto your guests as a 15-minute line.
Equipment and consumables
Glassware, ice, coolers, bar tools, napkins, and garnish. Ice alone surprises people. A summer event burns through far more than anyone plans for.
Service charge and gratuity
Some caterers bundle it, some do not. When it is not included, ten to twenty percent of the bar total is the normal range. Ask before you sign, not after.
What Bartenders and Licensing Really Cost
Bartender labor is the line most hosts underestimate. The U.S. Bureau of Labor Statistics puts the median bartender wage at $16.12 an hour as of May 2024, but that is the base rate for a bar job, not the billed rate for a private event.
Event bartenders are typically billed at $30 to $60 an hour each, and that rate covers travel, setup, breakdown, insurance, and the risk that comes with serving alcohol. A four-hour reception with two bartenders is really six or seven paid hours apiece once load-in and cleanup are counted.
Licensing is the part nobody sees. Our bar staff at Evolved Catering are licensed and insured and work in line with Maryland alcohol regulations, which is a different thing from hiring a friend who mixes a good drink. When something goes sideways at a party, that distinction is the whole ballgame.
For a 100-guest event we staff two bartenders as a baseline. If the room has two bar stations, or if the reception opens with a heavy cocktail hour, we add a third rather than let the line back up while the photos are being taken.
One more piece of hard-won advice: decide early who buys the alcohol. Some clients purchase their own and we advise on quantities. Others want us to handle it. Both work, but switching plans two weeks out is how budgets slip.
How to Pick the Right Bar Package
Start with the guest list, not the drink list. A crowd of 120 that includes kids and non-drinkers does not need the same bar as 60 adults at a milestone birthday.
Cap what you can control. A signature cocktail package plus beer and wine covers almost every guest, keeps the bar moving, and costs far less than an open bar nobody fully uses. Add a good mocktail and the non-drinkers stop feeling like an afterthought.
Coordinate the bar with the food. When cocktail hour runs long, guests drink more and eat less, and the dinner service backs up. Our guide to catering deposits and payment schedules covers how bar hours get locked into a contract, which is where most overtime disputes start.
Two more reads worth your time: how much to tip a caterer if gratuity is not bundled, and how many servers you need for 100 guests if you are still sizing your total staffing. If your day already has a full dessert and food lineup planned, see our graduation party catering ideas and costs for how bar service fits alongside a buffet.
Book bar service the same day you book food. Peak spring and fall weekends fill first, and a caterer who handles both keeps the kitchen and the bar on one timeline instead of two.
Bar Service Cost Questions
How many bartenders do I need for 100 guests?
Two is the working standard, based on one bartender per 50 guests. Add a third if you are running two bar stations, hosting a heavy cocktail hour, or serving a crowd that orders mostly mixed drinks rather than beer and wine.
What is the going rate for a bartender at a private event?
Event bartenders are usually billed at $30 to $60 an hour each, depending on experience and what the package includes. That rate covers setup, breakdown, licensing, and insurance, not just the hours guests see them working.
Can I supply my own alcohol and hire only the bartenders?
Often yes, and plenty of hosts do. Evolved Catering advises on quantities so nothing runs short, then handles staffing, ice, glassware, and mixers. Call 443-400-7336 and we will price both options for your event in Baltimore.
