Drinks & Bar calculators
Drink planning has real, published math behind it: a standard drink is defined by the NIAAA (12 oz beer, 5 oz wine, 1.5 oz spirits), a 750 ml bottle pours five glasses of wine, and the catering rule of thumb — two drinks per guest the first hour, one each hour after — has decades of industry use. These calculators run that math for your guest count and event length, then convert to the units you buy: cans, bottles, cases, pounds of ice and pots of coffee.

Which calculator should I use?
Use the beer or wine calculator when that’s all you’re serving — each converts straight to cases. For a full bar at a wedding or big event, the wedding alcohol calculator (in the Weddings hub) handles the beer/wine/spirits split. The soft drinks & water calculator covers everyone, works per hour, and matters more than hosts expect — non-drinkers, kids and hot afternoons empty coolers fast. Coffee and ice each have dedicated tools because their purchase units (pounds of grounds, bags of ice) follow completely different math.
