Sort every cost into fixed or variable
The calculation only works if the sort is honest. Fixed costs are what you owe whether the dining room is full or empty. Variable costs move with each ticket.
Hourly labor is the line operators most often misfile. Some of it is genuinely fixed, since a minimum crew opens the doors regardless, so treat the baseline crew as fixed and the flex hours as variable.
- /Fixed: rent and occupancy, salaried management, insurance, software, accounting, debt service
- /Variable: food, beverage, paper, flex hourly labor, card processing, delivery commissions
- /Semi-fixed: utilities, which carry a baseline plus a volume component
Put debt service in before you sign
A new payment raises the break-even line, and the honest way to evaluate financing is to add the payment to fixed costs and re-read the covers number.
If break-even moves from 92 covers a day to 104 and the room turns 130 on a good Saturday and 70 on a Tuesday, that is a real answer about whether the term is right.
What to do when the number is out of reach
A break-even above what the room can physically seat is not a marketing problem. It is a structure problem, and there are only 4 levers.
Raise the average check, widen the contribution margin by fixing food or labor cost, lower fixed costs, or lengthen the term on the debt so the monthly obligation drops. Volume is the slowest of the four and the one most plans lean on.

Break-even is not a feeling about a slow Tuesday. It is a sales number you can put on the wall. Enter what the doors cost to open each month and what each sales dollar costs you to produce, including the payment on anything you finance.
Base rent, CAM, property insurance, and taxes.
Utilities baseline, insurance, software, marketing, accounting.
Existing payments plus any payment you are considering.
Food, beverage, paper, hourly labor, and card processing.
Add the payment you are considering to debt service before you sign, not after. If the covers number is above what the room can physically turn, the answer is a longer term or a smaller amount.

The arithmetic
Contribution margin ratio = 1 - variable cost ratio. Break-even sales = fixed costs / contribution margin ratio. Covers needed = daily break-even sales / average check.
