Cost per cover is the total cost of serving each guest in your restaurant, including ingredients, staff, utilities and a share of operating expenses. It is key to setting prices and measuring efficiency.
Cost per cover (also called cost per guest or unit cost per customer) is a financial metric that calculates how much it costs the restaurant to serve each guest who sits at a table, taking into account all the business's operating expenses. Unlike food cost per dish, which only measures the ingredient cost of a specific preparation, cost per cover takes a complete view: the cost of the ingredients consumed (food cost + a share of beverage cost), the cost of the staff who look after the guest (from arrival to payment), the utilities used (electricity, gas, water, cleaning products), consumables (napkins, paper placemats, single-use items) and a share of fixed costs (rent, insurance, depreciation) allocated to each guest served. Cost per cover answers a fundamental profitability question: "how much does it cost me to have a guest come in to eat?". The difference between this cost and the average spend is the margin per cover, which multiplied by the number of guests gives the restaurant's operating profit.
Cost per cover varies enormously by type of venue: a highly optimised fast-food outlet may have a cost per cover of €3–5, a casual restaurant €12–18, a mid-to-upmarket restaurant €20–30 and a gastronomic restaurant €40–80 or more. These differences reflect not only ingredient cost (the most visible part), but also service intensity (more staff per guest in fine dining), table occupancy time (a higher occupancy cost per guest if they stay 2 hours rather than 45 minutes) and the level of operational sophistication (tableware, glassware, linen). Cost per cover should be calculated regularly (monthly or quarterly) and compared with average spend to check the business is viable: if cost per cover is €18 and average spend is €22, the margin per cover is just €4 (18%), which may not be enough to generate a profit once contingencies and reinvestment are covered. The usual target is for cost per cover to be 60–75% of average spend, leaving a 25–40% margin for operating profit.
Cost per cover = Total expenses for the period / Number of covers served
Cost per cover is calculated by dividing total operating expenses for a period by the number of guests (covers) served in the same period. For a monthly figure: if your total expenses for the month are €36,000 (including ingredient purchases, payroll, rent, utilities, marketing, maintenance and all other operating expenses) and you served 2,400 covers, cost per cover is 36,000 / 2,400 = €15. This overall figure is useful but can be refined by breaking it down: ingredient cost per cover (total food + beverage cost / covers), staff cost per cover (total payroll / covers), occupancy cost per cover (rent + utilities / covers) and other costs per cover. This breakdown shows which line is pushing cost per cover up most.
A useful variant is to calculate variable cost per cover (only the costs that vary with the number of guests: ingredients, the variable part of utilities) alongside total cost per cover. Variable cost per cover is more stable and helps set minimum prices: you should never sell below variable cost per cover, because every additional guest would generate a direct loss.
Your casual restaurant had these expenses in March: food and drink purchases €13,200, payroll and Social Security €14,400, rent €3,600, utilities €1,680, marketing €480, maintenance €360, insurance and accountant €480, other expenses €600. Total expenses: €34,800. You served 2,320 covers. Cost per cover: 34,800 / 2,320 = €15.
Your average spend was €26, so the margin per cover is €11 (42%). Breaking it down: ingredient cost per cover = 13,200 / 2,320 = €5.69. Staff cost per cover = 14,400 / 2,320 = €6.21. Occupancy cost per cover = (3,600 + 1,680) / 2,320 = €2.28.
Other costs per cover = (480 + 360 + 480 + 600) / 2,320 = €0.83. Total: €15. You notice that staff cost per cover (€6.21) is higher than ingredient cost (€5.69), which is normal in restaurants with table service but tells you staff efficiency is critical. If next month you serve 2,600 covers with the same fixed costs, cost per cover falls to €13.38 (fixed costs are spread across more guests), raising your margin to €12.62 per cover.
That is why increasing guest volume (occupancy and turnover) improves profitability: each additional guest has a marginal cost lower than the average cost because they don't add to fixed costs.
Cost per cover matters because it is the metric that links all of the restaurant's costs to the basic unit of revenue: the guest. While other metrics measure partial aspects (food cost only measures ingredients, labour cost only staff), cost per cover gives you a complete picture of how much each guest costs you and therefore the minimum you need to charge them so as not to lose money. That perspective is essential for three critical decisions. First, pricing: if your cost per cover is €18 and you want a 30% margin, your target average spend must be at least €25.70.
If your current average spend is lower, you have a pricing problem, a cost problem or both. Second, assessing promotions: when you offer a 20% discount to bring in guests on quiet days, you need to check that the discounted price is still above variable cost per cover; otherwise every promotional guest generates a loss instead of helping to cover fixed costs. Third, sizing the business: cost per cover combined with your capacity and turnover determines your break-even point. If your cost per cover is €16, your average spend is €24 (an €8 margin) and you have €20,000 of fixed costs a month, you need 20,000 / 8 = 2,500 covers a month to break even.
If your physical capacity doesn't allow that volume, the business model isn't viable and you need to cut costs, raise prices or increase capacity. Cost per cover is also useful for comparing efficiency between restaurants in the same group or against industry benchmarks: a cost per cover significantly higher than competitors' points to inefficiencies that need investigating.
Zindra automatically calculates your monthly cost per cover and breaks it down by line (ingredients, staff, occupancy, other), comparing it with average spend to show the real margin per guest. Dashboards let you track how cost per cover evolves and alert you when it moves away from your targets, helping you spot inefficiencies before they hit profitability.

Food cost is the percentage of a dish's selling price that goes on the cost of its ingredients. It is the single most important indicator of how profitable your menu is.
Average spend (the average ticket) is the average amount each customer (or table) spends in your restaurant. It is a key indicator of commercial performance and of how well your menu works.
Prime cost (coste primo in Spanish) is food cost plus staff cost. It is the most complete measure of a restaurant's direct operating cost and should stay between 55% and 65% of turnover.
Labour cost is the percentage of turnover that goes on staff. In restaurants, a healthy benchmark ranges from 25% to 35% depending on the type of venue.
Contribution margin is the difference between a dish's selling price and its variable cost (mainly ingredients). It shows how much each dish contributes towards fixed costs and profit.
The break-even point is the level of sales at which a restaurant covers exactly all its costs (fixed and variable), making neither a profit nor a loss. It is the minimum turnover needed to survive.
KPIs (Key Performance Indicators) are the key metrics that measure a restaurant's performance in its critical areas: sales, costs, productivity, guest satisfaction and profitability.
