Food & beverage minimum calculator

Plug in a headcount and what a typical guest spends to see whether a group will clear your minimum, how big the shortfall would be, and what the bill looks like with service charge and tax. Every result shows the formula behind it.

This assumes service charge and tax apply to the higher of actual spend and the minimum, which is common but not universal - some venues charge them only on actual spend, and tax rules on service charges vary by state. Room fees aren't included. It's arithmetic on your inputs, not pricing, tax, or legal advice.

How an F&B minimum works

A food and beverage minimum is the amount a group agrees to spend on food and drink in exchange for a private room or buyout. If they spend more, they pay what they spent. If they spend less, the difference is still owed - usually shown on the final bill as a “minimum shortfall” or room charge. It protects the revenue you'd have made from that space on a normal night without charging a flat rental fee up front.

A worked example

A group of 40 books your back room with a $2,000 minimum. From past events you expect about $28 of food and $18 of drinks per person:

  • Projected spend: 40 × ($28 + $18) = $1,840
  • Shortfall: $2,000 − $1,840 = $160
  • Billed toward F&B: $2,000 (the higher of the two)
  • Service charge at 20%: $400 · tax at 8%: $160
  • Estimated F&B total: $2,560

The same inputs tell you the group would need 44 guests at that spend to clear the minimum on their own (⌈$2,000 ÷ $46⌉), or about $50 per guest at 40 people. That's a useful number to share up front: it lets the host decide whether to upgrade the menu or accept a small room charge, instead of being surprised on the night.

Things to decide before you quote a minimum

  • • What counts toward it. Food and drink only? Does a cake fee or a corkage fee count? Say so in writing.
  • • Pre- or post-tax and service charge. Most venues set minimums before tax and service charge; whichever you choose, state it on the proposal.
  • • Day and season. A Saturday in December displaces far more regular business than a Tuesday in February. Many venues set different minimums by day of week.
  • • How the shortfall is shown. A line item called “room minimum shortfall” is clearer for the host than a vague “room fee” added later.
  • • Guest count changes. If the group shrinks, the minimum usually doesn't - spell that out in the contract.

Put the minimum on a real proposal
