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

In short


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.

A bar has three pricing models. In the first model, you pay one price for each guest and the venue serves without limit. In the second model, you pay for each drink that the staff pour. In the third model, your guests pay at the bar. Each model puts the risk in a different place. Model one puts the risk on you. Model two also puts the risk on you, but only for what your guests drink. Model three puts the risk on your guests.

Now look at the data. Only 6 percent of American couples choose model three. 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. Here are the figures with the cost for each guest.

Bar model Share of couples Typical cost for each guest
Full open bar 58% 15–45 USD (couples), 40–100 USD (vendor quotes)
Beer and wine only 17% 25–45 USD
No alcohol 9% 0 USD
Cash bar 6% 0 USD to you

Look at the first row again. Couples report 15 to 45 dollars for each guest. Bar companies quote 40 to 100 dollars. The two ranges hardly touch.

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.

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, which sits in the middle of the range that couples report.

Billed on Guests billed Cost Cost for each guest who drinks
Full guest list 120 3,600 USD 41 USD
Adults only 105 3,150 USD 36 USD
Guests who drink 87 2,610 USD 30 USD

Check the model against a figure that it did not use. The Knot reports 1,500 to 4,500 dollars for 100 guests, and an average of 2,800 dollars. Our 120-guest wedding lands at 3,600 dollars. The number sits inside the published band. 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:

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

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 much does an open bar cost for each guest?

Couples in The Knot 2025 Real Weddings Study report 15 to 45 dollars for each guest. Bar companies quote 40 to 100 dollars. Use the lower range 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. The figure changes with the region. The Northeast is the most expensive and the Southwest is the least expensive.

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.
