Restaurant Table Occupancy Break-Even Calculator
Find the seat occupancy needed for a restaurant service period to cover fixed operating cost. Available seats, service duration, average stay, average check, and variable cost percentage translate capacity into possible covers and show the break-even covers, occupancy rate, and sales.
Calculator
Planning inputsFormula
Contribution per cover = average check × (1 − variable cost %). Capacity covers = seats × service minutes ÷ average stay. Break-even occupancy = fixed cost ÷ contribution per cover ÷ capacity covers.
What the result means
The main result translates the entered operating assumptions into a comparable planning measure. Review the supporting values to understand which input is driving the estimate.
This is a planning estimate. Actual field or restaurant results can vary with conditions, timing, measurement, and operating choices.
Example calculation
With 80 seats, five service hours, a 90-minute stay, and a $32 check at 38% variable cost, contribution is $19.84 per cover. A $3,200 fixed cost requires 161.29 covers out of 266.67 capacity, or 60.48% occupancy.
Tips for better results
- Use contribution margin, not the full check, to cover fixed cost.
- Treat theoretical capacity as a planning ceiling, not a promise.
- Run separate cases for lunch, dinner, and events.
- Review the result if stay length or check average changes.
Frequently asked questions
What does break-even occupancy mean for a restaurant?
It is the share of theoretical seat capacity needed to generate enough contribution margin to cover entered fixed service cost.
Why must variable cost stay below 100%?
At 100% or more, each sale provides no positive contribution toward fixed cost.
Can break-even occupancy exceed 100%?
Yes. That signals the stated service capacity and economics cannot cover fixed cost.
Does the capacity estimate account for uneven table sizes?
No. It is seat-based and assumes seats can be used evenly over the service period.
Should rent be included in fixed service cost?
Include the portion allocated to the measured period if that matches the decision you are evaluating.
