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.

How Much Alcohol for 75 Wedding Guests?
75 guests is one of the most common sizes for a mid-size wedding, and the alcohol order starts to feel real at this number. With 64 drinking guests over 4 hours, plan for 26 bottles of wine, 2 cases of beer, and 4 bottles of spirits. Budget between 522 and 854. The most expensive mistake at this size is buying before RSVPs are confirmed. A 10% no-show rate on 75 invites means 7 to 8 empty seats and roughly $80 to $140 in wasted bar budget.
At 75 guests, the difference between estimated and confirmed attendance can cost you $80 to $140 in surplus alcohol. iDoTogether locks in your headcount before you head to the liquor store.
