At 180 Drinks we provide bar services for events and weddings in Toronto and cities across Ontario. We created thisย alcohol calculator as a simple way to help our customers develop a preliminary liquor budget for their party or wedding.

To use this party alcohol calculator please enter your service time and guest count below to get a liquor budget for your event. The party alcohol calculator logic, and a manual calculation example are below as well.
The logic our party alcohol calculator uses is simple. Itโs impossible to predict the exact proportions of distilled alcohol, wine, and beer your guests will consume at your event. The great news is that if you purchase your own liquor, you donโt have to worry about this when developing your preliminary event liquor budget because you can return any unused product in saleable condition for a full refund in Ontario. Since you can return unused liquor it becomes simple to establish a conservative liquor budget for your event based on the maximum your guests will consume.
You can assume each guest will consume one standard distilled alcohol drink (43 ml of 1.5oz) per hour per guest. Why base your budget on distilled alcohol you ask? Generally distilled alcohol is slightly more expensive than a standard drink of beer (341 ml or 12 oz) or wine (142 ml or 5oz) which makes your liquor budget conservative. If you are serving beer or wine you can simply change the bottle size, cost, and standard drink size to reflect these choices.
The following is a manual liquor budget calculation example using the same logic as our party alcohol calculator .ย
Liquor Type: Distilled Alcohol
Service Time: 4 Hours
Guest Count: 100 Guests
Bottle Cost: $28

Number of Drinks = 4 Hours x 100 Guests
Number of Drinks = 400 Drinks
Amount of Liquor = Number of Drinks x Standard Drink Size
Amount of Liquor = 400 Drinks x (1.5 oz or 43 ml)
Amount of Liquor = 17,200 ml or 600 oz
Number of Bottles = Amount of Liquor รท Bottle Size
