Wedding Alcohol Calculator Formula
TSS = Total Standard Servings
G = Total Adult Guests
D = Percentage of Drinkers (%)
H = Event Duration (Hours)
R = Average Drinks per Drinker per Hour (1.2 – 1.5)
Wine Bottles = (TSS * (W / 100)) / 5 Servings/Bottle
Beer Cases = (TSS * (B / 100)) / 24 Servings/Case
Liquor Bottles = (TSS * (L / 100)) / 17 Servings/Bottle (750ml)
Variables Explanation
- Total Adult Guests (G): The total number of adults attending your wedding.
- Event Duration (H): The total hours the bar will be open.
- Percentage of Drinkers (D): An honest estimation of how many guests will consume alcohol (typically 80% – 90%).
- Average Drinks per Drinker per Hour (R): Standard is 1.2 drinks, but you can increase this for heavy-drinking crowds (up to 1.5) or decrease for daytime/formal events (down to 1.0).
- Preference Percentages (W, B, L): Your estimated split of total consumption between Wine, Beer, and Liquor/Cocktails. Must sum to 100%.

What is alcohol for wedding calculator?
The Wedding Alcohol Calculator is an essential planning tool that helps couples move from guessing to making educated estimates on beverage quantities. It relies on a few key variables—the number of guests, the length of the event, and established industry consumption rates—to project the total number of standard alcoholic servings required.
The calculator’s true value lies in the final step: breaking down the total servings into practical purchasing units. By factoring in your guests’ preference for wine, beer, or liquor, it converts the abstract “total servings” number into concrete quantities like “number of wine bottles” and “number of beer cases,” ensuring you purchase just the right amount to keep the celebration flowing smoothly.
How to Calculate alcohol for wedding calculator (Example)
- Determine Total Consumption Time: Assume 100 guests, 85% of whom drink, over a 5-hour reception.
- Calculate Total Servings (TSS): With an average rate of 1.2 drinks/hour, the calculation is: 100 Guests * 0.85 (85%) * 5 Hours * 1.2 Drinks/Hour = 510 Total Standard Servings.
- Allocate Servings by Preference: Assume preferences are Wine (40%), Beer (35%), Liquor (25%).
- Wine Servings: $510 \times 0.40 = 204$ servings
- Beer Servings: $510 \times 0.35 = 178.5$ servings
- Liquor Servings: $510 \times 0.25 = 127.5$ servings
- Convert Servings to Purchasing Units: Divide servings by standard unit counts (5 for wine bottle, 24 for beer case, 17 for liquor bottle).
- Wine Bottles: $204 / 5 = 40.8$ bottles (Round up to 41)
- Beer Cases: $178.5 / 24 = 7.44$ cases (Round up to 8)
- Liquor Bottles: $127.5 / 17 = 7.5$ bottles (Round up to 8)
Frequently Asked Questions (FAQ)
How many drinks do guests typically consume at a wedding?
Industry standards suggest an average of 1 to 1.5 drinks per person per hour. Our calculator uses a default of 1.2, but you should adjust this based on your crowd’s known habits and the event’s intensity.
Why must the preference percentages (Wine, Beer, Liquor) equal 100%?
These percentages represent the total percentage split of the alcohol consumed. If the total is less than 100%, the calculator will underestimate the total servings required. If it exceeds 100%, it will overestimate.
Should I round up or down for the final bottle count?
Always round up to the nearest whole unit (bottle or case). It is significantly better to have a small surplus than to run out of a popular item during the reception.
What is the difference between “Total Guests” and “Percentage of Drinkers”?
“Total Guests” is the full headcount. “Percentage of Drinkers” accounts for non-drinkers (e.g., children, pregnant guests, designated drivers), allowing for a more accurate consumption estimate.
