Frequently Asked Questions
For a 4 hour reception with 175 guests at average drinking levels, plan 60 bottles of wine, 6 cases of beer, and 10 bottles of spirits. Budget 1,252 to 2,042. This assumes 15% non-drinkers and a standard 50/25/25 wine, beer, spirits split.
Buy your order in stages. Place a preliminary order 6 weeks out based on your estimate, then confirm quantities 3 weeks out once RSVPs are finalized. Many wholesale clubs and liquor stores allow returns on unopened cases, which limits your downside if fewer people attend.
It provides a strong planning baseline using industry averages: 1 drink per guest per hour, a drink split based on your selected event style, plus standard servings per bottle. Use the Event Style selector to match your crowd. A backyard BBQ skews heavily toward beer while a wine dinner needs far less spirits.
Yes. Use the Event Style selector to match your event type. Backyard BBQ skews heavily toward beer (65%), Wine Dinner is 70% wine, and Open Bar puts more weight on spirits (50%). Each preset uses real world crowd averages for that event type.
Use the drinking level toggle. Light works well for daytime or family heavy events, Average fits most receptions, and Heavy is better for bar forward crowds.
Absolutely. Kids, pregnant guests, and teetotalers all reduce your actual alcohol need. Use the Non Drinker % slider to exclude them from the drink calculations. The default 15% is a reasonable starting point for a typical mixed age crowd.
The champagne card accounts for a single toast glass for every guest, including non drinkers, since most people will take a glass even if they don't usually drink. At roughly 6 glasses per 750ml bottle, this is a separate purchase from your reception alcohol.
Yes, a 10-15% buffer is standard for larger weddings. But remember: the best way to protect your budget isn't guessing your buffer. It's having a accurate, confirmed headcount before you head to the liquor store.
No. This calculator estimates alcohol only. Plan mixers, water, soda, juice, coffee, and ice separately based on your menu and venue requirements.
Finalize your major order 4 weeks out, right after your RSVP deadline. (Pro-tip: If you use iDoTogether to collect RSVPs, your dashboard will show you exactly when 100% of your guests have answered, so you aren't guessing when it's safe to buy).
