Is an open bar package cheaper than paying per drink?
The useful comparison is marginal spending. A package usually charges for a guest regardless of whether that guest drinks, while a per-drink model follows actual drink orders. The right choice depends on the package price, the share of guests who drink, the average drinks per drinking guest, and the actual menu prices.
How the calculator works
The package total is guests multiplied by the package price per guest. The per-drink estimate first removes the non-drinker share, then multiplies the remaining drinking guests by the total drinks per drinking guest and the average drink price. Event hours are displayed for context; because the drink input is a total for the whole event, hours do not double-count consumption.
Methodology
| Calculation | Formula |
|---|---|
| Package total | Guests × package price |
| Drinking guests | Guests × (1 − non-drinker %) |
| Per-drink total | Drinking guests × drinks per drinking guest × average drink price |
| Break-even drinks | Package price ÷ [(1 − non-drinker %) × drink price] |
Examples
Low consumption
For 100 guests, 30% non-drinkers, a $65 package, 2 drinks per drinking guest, and $12 average drinks, the package is $6,500 while per-drink spending is about $1,680. The per-drink model is much lower under those assumptions.
Moderate consumption
With 4 drinks per drinking guest, the package remains $6,500 while the per-drink estimate becomes about $3,360.
Higher consumption planning case
With 5 drinks per drinking guest, the per-drink estimate becomes about $4,200. This illustrates price sensitivity; it is not a recommendation to drink more.
What can change the answer?
Contract minimums, taxes, service charges, premium-drink surcharges, bartender fees, and whether children or non-drinkers are charged can materially change the real comparison. Put comparable all-in numbers into the calculator whenever the venue provides them.
Common mistakes
- Comparing the package price with a single drink price without multiplying by drinking guests and expected orders.
- Ignoring non-drinkers when the package charges every guest.
- Leaving service charges out of only one option.
- Treating the estimate as a forecast of individual drinking behavior.
FAQs
Is an open bar cheaper for a wedding?
Sometimes. Compare the package total with the estimated total of individually purchased drinks.
How do I calculate a wedding bar break-even point?
Divide the package price per guest by the expected per-drink cost per guest after accounting for non-drinkers.
Do non-drinkers matter in an open-bar comparison?
Yes. A package that charges every guest can be less attractive when a large share of guests do not drink alcohol.
Should I include service charges?
Yes. Use comparable all-in prices whenever possible.
Does event length change the calculation?
Only if your drinks-per-guest assumption is expressed differently. In this tool it is a total event assumption, so hours are contextual rather than an extra multiplier.
