Cash Bar or Open Bar: You Pay for the Guests Who Do Not Drink

2026-08-27

In short

• A cash bar means that your guests buy their own drinks. An open bar means that you pay and your guests drink at no cost. A limited bar sits between the two: you pay, but only for beer and wine.
• The Knot 2025 Real Weddings Study reports the bar split: 58 percent of couples give a full open bar, 17 percent give beer and wine only, 9 percent give no alcohol, and 6 percent run a cash bar.
• The same study reports an average alcohol bill of 2,800 dollars. The average wedding that year had 116 guests, so couples paid about 24 dollars for each guest. Bar companies quote 40 to 100 dollars for each guest.
• A per-guest bar package bills your full guest list. Approximately 15 to 20 percent of adults drink no alcohol, and children drink none. At a wedding of 120 people, you can pay for 120 and serve 87.
• That difference is a premium of 38 percent. It is the largest number in this article, and no bar company prints it.

Every year the same argument starts again. One side says that a cash bar is rude. The other side says that free alcohol is not a human right. Both sides are loud. Both sides miss the point.

Here is the point. The argument is about manners. Your invoice is about risk. These are different problems, and only one of them costs money.

What a cash bar and an open bar actually are

Three words cover almost every bar at almost every wedding.

An open bar means that you pay for the drinks and your guests pay nothing. The venue usually sells this as one price for each guest, for a fixed number of hours.

A cash bar means that your guests buy their own drinks at the bar. It costs you nothing. The name is old and it misleads: most bars now take cards, and some take cards only. Ask the venue what the bar accepts, then tell your guests, because a guest who brings no card and no cash cannot buy anything.

A limited bar, sometimes called a beer and wine bar or a hosted bar, means that you pay for part of the list. Beer and wine are free and spirits are not, or the bar is free until dinner and paid after it.

There is a fourth arrangement that has no marketing name, and it is the one that decides most invoices: consumption billing. The bar is open and free to your guests, and the venue counts the drinks and bills you for what was poured.

Each of these puts the risk of a thirsty room somewhere different. An open bar package puts it on you and fixes the price. Consumption billing puts it on you and does not fix the price. A cash bar puts it on your guests.

Now look at the data. Only 6 percent of American couples run a cash bar. The internet argues about the rarest option and ignores the two options that decide the bill.

Cash bar vs open bar: what each model costs

The Knot 2025 Real Weddings Study gives the shape of the American market. It surveyed couples who married in 2024, and its bar figures are still the latest that The Knot has published. Here are the shares, with a cost for each guest.

Now set that row against what couples actually spent. Across every bar model in the study, the average alcohol bill was 2,800 dollars, about 24 dollars for each guest. Bar companies quote 40 to 100 dollars for a full open bar. The cheaper beer and wine bars pull the average down, but not by enough to close that gap.

The reason is simple. A vendor quote is a price for a service. A newlywed figure is a receipt. A quote must cover the worst evening that the vendor can imagine, because the vendor carries the loss if the estimate is low. Your receipt records the evening that actually occurred.

Do not treat the two numbers as the same number. Budget with the receipt. Negotiate against the quote.

The premium nobody prints: a package bills your full guest list

This is the calculation that changes the decision.

Our wedding alcohol calculator starts from one rule. You must calculate alcohol on the adults who drink, not on the guest list. Children drink no alcohol. Between 15 and 20 percent of adults drink no alcohol.

A per-guest bar package does the opposite. The package bills each name on your list.

Take a wedding of 120 people.

• 15 of the guests are children. 105 adults remain.
• Between 15 and 20 percent of those adults drink no alcohol. Use the middle value. That removes 18 adults.
• 87 guests drink.

You pay for 120 guests. 87 guests drink. That is a premium of 38 percent before the staff pour one glass.

Ask the venue one question: does the package count children? If the venue removes the children, you pay for 105 and 87 drink. The premium falls to 21 percent. It does not fall to zero.

Now put money against the premium. Use 30 dollars for each guest. That sits in the middle of the 15 to 45 dollar budgeting range The Knot suggests, and a little above the 24 dollars that couples averaged.

Check the model against figures that it did not use. Couples in the study with more than 100 guests spent 3,535 dollars on alcohol on average, and the regional averages run from 2,393 dollars in the Southwest to 3,965 in the Northeast. Our 120-guest wedding lands at 3,600 dollars billed on the full list and 2,610 billed on the guests who drink. Both sit inside the range that couples actually paid. The model holds.

A package price for each guest is insurance. You pay a fixed premium, and the venue accepts the risk of a thirsty room. That trade can be correct. It is only correct if you know the size of the premium, and most couples never calculate it.

When each bar model is the right choice

The premium above does not make packages wrong. It makes them a decision.

Choose the package when your room drinks and you need one fixed number. A young guest list with few children and a late finish can drink through the premium. A fixed number also protects the budget from a surprise, and that has real value.

Choose consumption billing when your guest list has many children, many drivers, or many older guests. You then pay for what your guests drink. Ask for a cap in writing, and ask the staff to tell you when the bill reaches the cap.

Choose beer and wine only when you want to cut cost without a bar transaction. 17 percent of couples choose this model. It removes the expensive part of the bar and keeps the hospitality.

Choose a cash bar only if you tell your guests first. More on that below.

The cash bar is not the problem. The surprise is the problem.

Here is our position, and it is not the popular one.

A cash bar is not rude. A cash bar that your guests discover at the bar is rude.

The difference is information. A guest who knows about the cash bar brings a card and plans the evening. A guest who does not know arrives with no cash, queues, and then feels foolish in front of other guests. The money is small. The embarrassment is not.

This is a schedule problem, not a budget problem, and it belongs with the other rules that nobody writes down. We cover those rules in our guide to cross-cultural wedding guest etiquette, because the bar is the point where a guest from another country is most likely to guess wrong.

So if you choose a cash bar, do this:

• Put one line on your wedding website. Use plain words. “There will be a bar where guests can buy drinks.”
• Tell the guests who travel. They plan a budget for the trip, and the bar belongs in that budget.
• Give something free. A welcome drink and wine at the table cost little and change the evening.
• Check that the bar takes cards. A cash-only bar in 2026 is a bad experience.

Ask the venue these five questions before you sign:

• Does the package price count children and guests who do not drink?
• What time does the package start, and what time does it stop?
• What is the price for each drink if we change to consumption billing after midnight?
• Is the service charge inside the package price, or is it added after?
• Can we bring our own wine, and what is the fee for each bottle?

What we would do

We would not buy the package first. We would ask for both prices.

Ask the venue for the package price and for the price of each drink. Then use the guest count that drinks, not the guest list. Multiply. Compare the two totals. The comparison takes ten minutes and it is the only way to see the premium.

Then we would buy a package for the first part of the evening and change to consumption billing after midnight. The first hours hold the toast, the dinner and the dancing, and that is when a room drinks. After midnight the room is smaller and the drinking is slower, and a package for each guest then pays for people who went home.

The bar is also one of the first lines that moves between families when a budget becomes tight. We set out who pays for the wedding separately, because the answer changes who makes this decision.

And we would tell the guests. Whatever we chose, we would write one sentence about the bar where the guests could read it.

You do not need our software for the arithmetic above. A sheet of paper is enough. If you want the tools, the Multi-Currency Budget and the Vendor & Crew Tracker are free, and they keep the venue quote and the bar quote in the same place. The Virtual Sommelier & Bar Calculator is part of the premium package, and it converts a guest list into bottles and a cost.

Which model does your venue quote first, and did anybody tell you that the other model exists?

Frequently asked questions

What is a cash bar at a wedding?

A bar where your guests buy their own drinks. You pay nothing for the alcohol. The opposite is an open bar, where you pay and your guests drink at no cost, and between the two sits a limited bar, where you pay for beer and wine only.

Does a cash bar mean cash only?

Usually not any more. The name comes from a time when bars took nothing else. Most wedding bars now take cards and some take cards only. It is still worth asking the venue, and worth telling your guests the answer, because the guest who arrives with neither is the one who has a bad evening.

Is it normal to have a cash bar at a wedding?

It is uncommon in the United States. The Knot 2025 Real Weddings Study puts it at 6 percent of couples, against 58 percent who give a full open bar. It is far more ordinary in other countries, which is one reason guests who travel guess wrong about it.

Is a cash bar at a wedding rude?

No. A cash bar that your guests learn about at the bar is rude. Tell your guests before the day, give one free drink, and the objection disappears. Only 6 percent of American couples run a cash bar, so your guests may not expect one.

How do you tactfully say there is a cash bar?

Say it plainly, once, on the wedding website or the details card rather than on the invitation itself. “Drinks will be available to buy at the bar after dinner” works. So does “We will serve wine with dinner, and the bar will be open for anything else.” Avoid the words “cash bar”, which sound like an apology, and avoid jokes, which read as embarrassment. If the bar takes cards only, say so in the same sentence.

What are the cons of a cash bar?

There are four, and only the first one is about money. Guests who expected an open bar notice, especially at an American wedding, where only 6 percent of couples run a cash bar. Guests queue at the bar with cards instead of dancing. Guests who travel must budget for it. And the venue may still charge you: some bars ask for a bartender fee or a minimum amount of sales before they agree to run a cash bar, so ask for both numbers before you assume that it costs nothing.

How much does an open bar cost for each guest?

About 24 dollars for each guest is what couples actually paid. The Knot 2025 Real Weddings Study reports an average alcohol bill of 2,800 dollars, and the average wedding that year had 116 guests. The Knot suggests budgeting 15 to 45 dollars for each guest, and bar companies quote 40 to 100 dollars for a full open bar. Use the lower figures for a budget, and use the higher range when you negotiate.

What is the average alcohol cost for a wedding?

The Knot 2025 Real Weddings Study reports an average of 2,800 dollars, from couples who married in 2024. The region moves it, from 2,393 dollars in the Southwest to 3,965 in the Northeast and New England. The guest count moves it more, from 1,274 dollars at weddings of up to 50 guests to 3,535 at weddings of more than 100.

Does a bar package charge for children?

Many packages charge for every name on the guest list. Some remove children. You must ask, because the answer changes the cost by more than 10 percent at a wedding with many children.

Is an open bar cheaper than paying for each drink?

It depends on how many of your guests drink. A package is cheaper for a room that drinks a lot. Consumption billing is cheaper when your guest list holds children, drivers and older guests.

Can we serve only beer and wine?

Yes, and 17 percent of couples do this. The model removes the most expensive part of the bar, and your guests still pay nothing. It is the usual compromise between a full open bar and a cash bar.

Should we change to a cash bar after midnight?

It is a common compromise, but tell your guests. A bar that is free at 22:00 and paid at 00:30 surprises the guests who arrived late.

Can we bring our own alcohol to the venue?

Sometimes. The venue can charge a fee for each bottle that the staff open. Ask for that fee in writing before you buy the alcohol, because the fee can remove the saving.
