What Is the Wedding Alcohol Calculator?
The Wedding Alcohol Calculator helps you estimate the right amount of alcohol for your wedding. It uses inputs like guest count, event duration, drinking habits, and drink preferences to give you a detailed plan. This tool simplifies the decision-making process and reduces the chance of running out or overbuying alcohol.
Formula Used for Estimation
Drinking Guests:
Drinking Guests = Total Guests × (Drinking Percentage ÷ 100)
Total Drinks Needed:
Total Drinks = (Drinking Guests × 2) + (Drinking Guests × Drinks Per Hour × (Duration - 1))
Drink Type Servings:
Drink Type Servings = Total Drinks × (Drink Type Percentage ÷ 100)
Bottles Needed:
• Beer: 1 bottle per serving
• Wine: 1 bottle = 5 servings
• Spirits: 1 bottle = 17 servings
• Champagne: 1 bottle = 6 servings
Total Cost with Buffer:
Total Cost = (Beer Cost + Wine Cost + Spirits Cost + Champagne Cost) × (1 + Buffer Percentage ÷ 100)

Example Scenario
If you're hosting 100 guests for a 5-hour wedding, with 80% drinking guests and an average of 1.5 drinks per hour, the calculator will estimate how many bottles of beer, wine, spirits, and champagne you’ll need—plus tell you if you’re within your $1500 budget.
FAQs
Do I need to serve all types of alcohol?
No. You can adjust the percentages so that you only include beer and wine, for example. Just ensure the total adds up to 100%.
What happens if I go over budget?
The calculator will show how much you're over and suggest where you may want to reduce costs—for example, cutting back on champagne or spirits.
What if my guests drink more than average?
You can increase the "drinks per hour" value to better reflect your guests’ habits. You can also increase the buffer percentage to plan for extra.
Can I use this calculator for Other events?
Yes. While it’s designed with weddings in mind, it can be used for birthdays, anniversaries, or any large gathering with similar structure and alcohol needs.
