Wedding Bar Budget per Guest Calculator
Estimate a wedding bar’s total budget and cost per invited guest from drinking participation, expected consumption, beverage cost, fixed bar expenses, and contingency. The calculator distinguishes the cost per total guest from the cost per drinking guest, making it easier to compare an open-bar plan with venue or caterer package quotes.
Calculator
Consumption and bar costsFormula
Drinking guests = total guests × drinker rate
Beverage cost = drinking guests × drinks per drinker × cost per drink
Total budget = (beverage cost + fixed costs) × (1 + contingency)
Budget per guest = total budget ÷ total guests
Beverage cost = drinking guests × drinks per drinker × cost per drink
Total budget = (beverage cost + fixed costs) × (1 + contingency)
Budget per guest = total budget ÷ total guests
What the result means
The main result spreads the full bar budget across every attendee. The secondary cost per drinker is useful when comparing alcohol packages.
Alcohol prices, service rules, taxes, gratuities, permits, and liability requirements vary. Add any omitted charges to fixed costs.
Example calculation
For 150 guests, 75% drinking, four drinks each, and $3.50 per drink, beverage cost is $1,575. Adding $1,200 fixed costs and 10% contingency gives $3,052.50 total, or $20.35 per guest.
Tips for better results
- Separate product cost from venue selling price.
- Include ice, mixers, cups, garnishes, and delivery if not bundled.
- Use a lower drink count for a shorter reception.
- Compare quotes on the same tax and gratuity basis.
- Check return policies before intentionally over-ordering.
Frequently asked questions

Should bartender labor be entered as a fixed bar cost?
Yes, add labor and other non-consumption charges to fixed costs if they are not included elsewhere.
How should nonalcoholic drinks be handled?
Include their average cost in the per-drink estimate or add a separate allowance to fixed costs.
Does contingency apply to both beverages and fixed costs?
Yes. This calculator applies the selected contingency percentage to the combined subtotal.
