How many beers per person for a party?

Typically 1–2 drinks per hour per drinking guest. For a 5-hour party that is about 5–10 drinks per person. The calculator accounts for the duration and the pace.

How much to buy to be safe?

Buy about 10–20% more than the calculated need. Avoiding running out matters more than a small surplus, which you can use later.

How many beers are in a beer crate?

A standard beer crate usually holds 24 cans or bottles. The calculator converts the required amount into crates.

Should you provide non-alcoholic drinks too?

Yes. About 20–30% of guests will likely drink non-alcoholic options. Water, soft drinks and alcohol-free beer should always be available.

The beer crate calculator estimates how many beers or ciders you need for a party based on guests, duration and drinking pace. That way you avoid both running dry and an awkward surplus.

How the calculator works and what it’s for▾

How the amount is calculated

The tool first estimates how many guests drink, then multiplies that by the party length and the hourly drinking pace. The result is the total number of drinks needed.

For example, 20 guests with 80% drinking over a four-hour party at one drink per hour comes to about 64 drinks, just under three crates.

What you enter and what you get

Enter the number of guests, the party duration, drinks per hour per person and the share who drink as a percentage. You get the number of drinking guests, the total drinks, the crates needed and an estimated cost.

The cost estimate is based on roughly 1.50 dollars per drink and gives a rough budget for shopping.

Who it is for

It suits planning house parties, cabin trips, birthdays and summer gatherings when you want to buy the right amount in one go.

Expressing the result in crates makes shopping easier, since one crate holds 24 cans.

Tips for party planning

The estimate is based on an average pace, so buy a little extra — it is better to have leftovers than to run out.

Always offer non-alcoholic options and water too, so every guest has something to drink.
