Break Even Calculator for Restaurants
Restaurants do not sell units, they sell covers, and that changes how break-even works. The useful question is not how many dishes you must sell but how many guests must walk through the door each day — a number you can compare directly against your seat count and your realistic turn rate.
Enter your monthly fixed costs, your average check as the price, and your variable cost per cover — food plus the variable share of labour. The result converts straight into covers per day, which the section below then tests against physical capacity. A break-even number your dining room cannot physically produce is the most important thing to discover before signing a lease.

What each sale leaves over to pay down fixed costs.
Expected sales are below break-even — this period runs at a loss.
Break-even analysis assumes price and variable cost stay constant and that your sales mix is stable. Rerun it whenever your cost structure changes.

From monthly break-even to covers per day
Divide the monthly break-even in covers by the days you open. A restaurant needing 1,910 covers a month and opening 26 days needs about 74 covers a day — and that is the figure to test against capacity.
| Seats | Turns per day | Covers per day | Verdict at 74 needed |
|---|---|---|---|
| 40 | 1.5 | 60 | Not achievable — needs more turns or higher check |
| 40 | 2.0 | 80 | Achievable but with no headroom |
| 60 | 1.5 | 90 | Comfortable |
| 60 | 2.5 | 150 | Strong; break-even reached by mid-month |
| 80 | 2.0 | 160 | Strong |
Splitting labour into fixed and variable
Restaurant labour is the cost most often misclassified in break-even analysis, and getting it wrong moves the answer substantially.
- Fixed labour: salaried managers, the chef, and the minimum crew required to open the doors at all. This belongs in fixed costs — it does not fall if you serve twenty guests instead of eighty.
- Variable labour: additional servers, bussers and line cooks scheduled to demand. This belongs in variable cost per cover.
- A practical split for full service is roughly 40% of total labour as fixed and 60% as variable, but check it against your own rota rather than assuming.
- Treating all labour as variable understates break-even and makes a marginal site look viable. Treating it all as fixed overstates break-even and can make a good site look impossible.
- Remember payroll burden — taxes, insurance, workers' comp — which typically adds 15% to 30% on top of wages in both categories.
Levers that move restaurant break-even
| Change | Effect on break-even covers | Difficulty |
|---|---|---|
| Average check up $3 | Falls about 12% | Moderate — menu engineering, upselling |
| Food cost down 2 points | Falls about 3% | Moderate — portioning, supplier terms |
| Rent down $2,000/month | Falls about 5% | Hard once signed |
| Adding a lunch service | Spreads fixed costs over more covers | Hard — labour and demand risk |
| Beverage attachment up 10% | Falls about 6% | Easiest lever available |
Frequently asked questions
- How do I calculate break-even for a restaurant?
- Use average check as your price per unit and cost per cover — food plus variable labour — as your variable cost. Divide monthly fixed costs by the difference to get break-even covers per month, then divide by operating days for the daily figure you can compare against seats and turns.
- Should labour be a fixed or variable cost?
- Both. Salaried managers and the minimum opening crew are fixed; servers and line cooks scheduled to demand are variable. A common split for full service is 40% fixed and 60% variable. Classifying all labour as variable is the most common error and it makes break-even look considerably better than it is.
- What is a realistic number of seat turns?
- Fine dining typically achieves 1 to 1.5 turns per service, casual full service 2 to 3, and fast casual 4 or more. Multiply seats by turns to get your realistic capacity ceiling. If break-even requires more covers than that ceiling allows, the problem is the model rather than the marketing.
- How long should a new restaurant take to break even?
- Many operators plan for 6 to 18 months to reach consistent monthly break-even, and budget working capital accordingly. Reaching it in the first quarter is unusual. The critical planning number is not when you break even but how many months of losses you can fund before you do.
- Why does my break-even change every month?
- Because average check, sales mix and labour scheduling all move. A month with strong beverage sales has a higher contribution per cover and therefore a lower break-even. Recalculate monthly using actual figures rather than treating break-even as a fixed target set at opening.
