Wedding Bar Tab Calculator: Open Bar vs. Cash Bar Cost
Enter guest count, reception hours, drinks-per-hour, and the per-drink cost. The calculator shows your total for full open bar, beer and wine only, limited bar with signature cocktails, and cash bar — plus what your guests would collectively spend at a cash bar.
The bar is the second-biggest line after food
A 120-person wedding over 5 hours with full open bar: $4,500-$7,500 on alcohol alone. That's more than your dress, more than your flowers, sometimes more than your photography. And most couples don't realize the true cost until the caterer's final invoice arrives.
The four bar formats, ranked by guest experience
1. Full open bar (most expensive, best guest experience)
Premium liquor, wine, beer, signature cocktails. $32-$45 per guest for a 5-hour reception. Zero friction for guests. Expect heavy pouring in hour 1 (people arriving thirsty and hungry) and tapering after dinner.
2. Beer & wine only (40% cheaper, nearly as good)
Just beer and wine, maybe a specialty cocktail. $18-$25 per guest. Guests who want liquor are mildly annoyed; most guests don't notice. Surprisingly good alternative if your crowd skews younger (craft beer, wine).
3. Limited bar with signature cocktails
Beer, wine, and 1-2 pre-batched signature cocktails named after the couple. $24-$32 per guest. Feels curated and special. Controls cost (you're not pouring 18 types of liquor). Strong middle-ground option that more couples are picking in 2026.
4. Cash bar (cheap for you, expensive for guests)
Guests pay per drink. You still cover bartender fees ($350-$500 per bartender). Etiquette: frowned on at most formal weddings, but common at casual/brunch/daytime receptions. Partially-paid alternative: you cover beer, wine, and signature; guests pay for top-shelf liquor.
What actually drives your bar total
Drinks per hour
The industry planning number is 1.5 drinks per person per hour. Reality:
- Hour 1 (cocktail hour): 2-2.5 drinks. Guests arrive thirsty.
- Hour 2 (dinner): 1-1.5 drinks — they're eating.
- Hour 3 (first dances, toasts): 1.5-2 drinks.
- Hour 4 (dancing): 1-1.5 drinks.
- Hour 5 (late): 0.5-1 drinks — people are tired.
Average it to 1.5 drinks/hour and you'll be close. The bigger risk is underestimating hour 1.
Liquor vs. wine vs. beer split
Typical wedding crowd: 35% beer, 35% wine, 30% liquor. Adjust if your crowd skews different — a 60% liquor crowd needs more bartenders (mixing takes time) and more premium spirits. Talk to your bartender about this in the pre-wedding meeting.
Bartender count
One bartender per 75 guests is the minimum. One per 50 is comfortable. One per 100 means a long line in hour 1. At $350-$500 per bartender for the event, adding a second or third is a small cost that dramatically improves flow.
Bring-your-own-booze: the big savings play
If your venue allows it, buying your own alcohol and paying corkage can cut bar cost by 40-60%. A 120-person wedding with full bar:
- Venue-supplied bar: $5,400 at $9/drink × 1.5 × 5hr × 120 people
- BYO at Costco/Total Wine: $1,800 in booze + $700 corkage + $700 bartenders = $3,200
Savings: $2,200. Downsides: you haul the booze, you manage leftovers, and many venues flat-out prohibit BYO or charge corkage fees so punitive they kill the math. Check the contract before getting excited.
The cash bar etiquette question
Traditional etiquette: hosts pay for what guests consume. By that rule, cash bar is gauche. But the rule was written when weddings were smaller, alcohol was cheaper, and incomes stretched further. In 2026, plenty of couples do partially-paid or casual cash bars with zero guest backlash — especially if it's clear that the budget tradeoff was elsewhere (better food, live music, nicer venue).
If you go cash bar, tell guests in advance (on the wedding website, not the invitation). Set up a tip jar for the bartenders — they're still working the same shift. Consider covering the first round or the signature cocktail as a gesture.
How to manage the hour-1 rush
- Start the bar 15 minutes before ceremony ends if the venue allows. Guests walking into cocktail hour find the bar already staffed and pouring.
- Signature cocktail pre-batched. Pour-and-serve takes 8 seconds vs. 45 seconds for a made-to-order old-fashioned.
- Water and nonalcoholic stations separate from the bar. Mocktails at a side station remove 15-20% of bar traffic.
- Pass trays during cocktail hour. Servers walking with champagne and signature cocktails cuts bar line entirely for the first 30 minutes.
Don't forget the tip
Bartenders get tipped. If service charge already covers gratuity, put a cash tip jar out. If it doesn't, plan $50-$100 per bartender cash tip (in their envelope, from you) or 10-15% of the bar bill. See the Tip Calculator for the full breakdown.
When the bar bill is out of budget
Cheapest moves that keep guest experience high:
- Drop from full bar to beer + wine + signature cocktail. Saves ~30%.
- Shorten the reception by 1 hour. Saves 15-20% on bar and overtime.
- Switch from premium to call-brand liquor. Most guests can't tell.
- Do BYO if the venue allows. Biggest single save.
Run these scenarios in the calculator and see what each actually saves. Then cross-check the Wedding Budget Calculator to confirm you're redirecting the savings, not just vaporizing them.
