Are you planning a wedding and dreaming of an open bar to celebrate with your guests? While it's an exciting addition, it's essential to understand the potential costs involved. This comprehensive guide will walk you through the process of calculating the open bar wedding cost, ensuring you stay within your budget while keeping your guests happy and hydrated.
Understanding Open Bar Wedding Costs
An open bar at a wedding typically means that alcoholic beverages are complimentary for guests throughout the event. The cost of an open bar can vary greatly depending on several factors. Here's a breakdown of the key elements that contribute to the overall cost:
- Duration of the event: The longer the bar is open, the more drinks will be served, and the higher the cost.
- Number of guests: More guests mean more drinks will be consumed.
- Type of alcohol served: Premium liquor, craft beers, and specialty cocktails will cost more than well liquor and domestic beers.
- Non-alcoholic beverages: Don't forget to budget for water, soda, and other non-alcoholic drinks.
- Staffing: You'll need to hire bartenders and possibly other staff to manage the bar.
- Bar setup and glassware: Consider the cost of renting glassware, ice, and other bar supplies.
Calculating Your Open Bar Wedding Cost
To calculate the cost of an open bar at your wedding, follow these steps:

1. Estimate the number of drinks per guest
On average, guests consume about 1.5 to 2 drinks per hour. Multiply the number of guests by the number of hours the bar will be open and the average drinks per hour to estimate the total number of drinks served.
2. Determine the cost of drinks
Research the cost of alcoholic beverages in your area. A good rule of thumb is to budget around $3 to $7 per drink, depending on the type of alcohol served. Here's a rough breakdown:
- Well liquor: $3 - $5 per drink
- Call liquor (e.g., gin, vodka): $4 - $6 per drink
- Premium liquor (e.g., top-shelf vodka, bourbon): $6 - $7 per drink
- Champagne and sparkling wine: $5 - $10 per drink
- Craft beer: $4 - $7 per drink
- Specialty cocktails: $5 - $10 per drink
3. Calculate the cost of non-alcoholic beverages
Budget around $1 to $2 per guest for non-alcoholic drinks, such as water, soda, and juice.

4. Factor in staffing and bar setup costs
Bartenders typically charge between $25 to $50 per hour, depending on your location and the level of service. You'll also need to budget for glassware, ice, and other bar supplies. Rental costs can vary, so be sure to get quotes from local vendors.
