About this calculator
The Party Calculator for food and drinks helps estimate the ideal quantities for your event, avoiding excesses or shortages. It considers the meal type (cocktail or dinner) and the number of guests. For food, it uses 150 grams per person for cocktails and 350 grams for dinners. For drinks, it calculates 0.3 liters per person per hour of event, multiplied by total hours and guests. This tool is useful for birthday parties, get-togethers, weddings, and family reunions.
The drink calculation assumes each person consumes about 300 ml per hour. This includes soft drinks, juices, and water. For alcoholic beverages, adjust according to the guests' profile. The calculator does not differentiate drink types but serves as a base for total volume. Remember that factors like weather and event duration can affect consumption. Use the results as a starting point and adjust based on your experience.
When using the calculator, enter the number of guests, event duration in hours, and meal type. The result shows total food in grams and drinks in liters. For parties with children, reduce food portions to about 100 grams per child. For long events, consider an extra 10% to 20% for unforeseen circumstances. The tool does not replace common sense but provides a reliable basis for planning.
Frequently asked questions
How to calculate drinks for an alcohol-free party?
The calculator uses 0.3 liters per person per hour regardless of type. If only soft drinks and juice, keep the value. For alcoholic drinks, adjust according to guests' profile.
Does the calculator consider children?
Not specifically. For children, reduce food portions to about 100 grams. Drinks can be kept as is, but children consume less, so you can reduce the total.
What if the party lasts more than 4 hours?
The calculator multiplies consumption per hour. For long events, add 10% to 20% margin as consumption may increase over time.
Do I need different types of drinks?
The tool gives total volume. Divide among soft drinks, juice, water, and alcoholic drinks as you prefer. A suggestion is 50% soda, 30% water, and 20% juice for alcohol-free parties.
How to use for a barbecue?
For barbecue, treat it as dinner (350 g/person). Drinks follow the same rule. Remember to include sides and desserts separately.
