Party Drink Planning Tips

Planning drinks for a party can be challenging. Here are some helpful tips to make your event a success:

General Guidelines
  • Standard Drink Sizes: Beer (12 oz), Wine (5 oz), Spirits (1.5 oz)
  • Bottles Yield: Wine (5 glasses per 750ml bottle), Liquor (17 drinks per 750ml bottle), Beer (1 drink per bottle/can)
  • First Hour Rule: Guests typically consume more drinks during the first hour
  • Ice: Plan for 1 pound of ice per guest for drinks plus additional for cooling beverages
Party Hosting Tips
  • Offer water stations alongside alcoholic beverages to keep guests hydrated
  • Consider seasonal drinks that match the theme or weather of your event
  • Label drinks or create a drinks menu to help guests find what they want
  • Have a variety of glassware appropriate for different beverages
  • Provide non-alcoholic options that are just as appealing as alcoholic ones

What Is the Party Drink Calculator?

The Party Drink Calculator is a practical tool that helps you estimate how much alcohol and non-alcoholic beverages you’ll need for your event. Whether you’re organizing a birthday bash, wedding reception, office party, or backyard barbecue, this tool makes it easier to prepare the right amount of Drinks based on your guest list and event duration.

It eliminates guesswork by calculating drink quantities based on real-world factors like guest count, drinking habits, beverage preferences, and even buffer stock for last-minute needs.

How It Works

The calculator uses straightforward math to determine the total number of drinks you’ll need and breaks them down by drink type—beer, wine, spirits with mixers, and non-alcoholic options. It also includes a built-in option to account for cost estimation and buffer stock.

Core Formula:
Total Alcoholic Drinks = (Drinking Guests × Drinks Per Hour × 1.5) + (Drinking Guests × Drinks Per Hour × (Event Duration − 1))

Total With Buffer = Total Alcoholic Drinks × (1 + Buffer Percentage ÷ 100)

Why Use This Calculator?

  • Helps avoid under- or overbuying drinks.
  • Breaks down quantities by drink type and guest preference.
  • Includes mixer and garnish recommendations for spirits.
  • Estimates total cost and cost per guest if desired.
  • Useful for party planners, hosts, event organizers, and caterers.

How to Use the Calculator

Follow these steps to plan drinks for your event:

  1. Enter guest count: Input the number of adult guests attending your party.
  2. Set the duration: Choose how many hours the event will last.
  3. Estimate drinkers: Specify what percentage of guests will drink alcohol and how many drinks they typically consume per hour.
  4. Choose beverage types: Select whether you’ll be serving beer, wine, spirits, and/or non-alcoholic drinks.
  5. Fine-tune preferences: For each category, indicate what percentage of drinkers prefer that beverage and how many varieties you want to offer.
  6. Add a buffer: Include extra drinks as a cushion by adding a buffer percentage.
  7. Enable cost estimation (optional): Check this box if you want a rough estimate of the total cost and per-person cost.
  8. Click “Calculate” to get your custom shopping list.

Frequently Asked Questions (FAQ)

What if my event lasts more than 5 hours?

Can I use this for non-alcoholic events?

Yes. You can uncheck all alcoholic beverages and only use the non-alcoholic section to calculate soft drink needs.

Is the cost estimate accurate?

The cost is an estimate based on average prices: $1.50 per beer, $15 per wine bottle, $20 per spirits bottle, and $3 per non-alcoholic 2L bottle. Real prices may vary.

What if the wine percentages don’t add to 100%?

The calculator will alert you and require the red and white wine percentages to total exactly 100% for accurate results.
