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.
The break-even point (punto muerto in Spanish) is the level of activity (expressed in euros of turnover or in number of covers) at which total revenue exactly equals total costs, giving a profit of zero. Below the break-even point the restaurant makes a loss; above it, it makes a profit. Knowing this figure is absolutely critical for any restaurant manager because it is the minimum threshold for the business to survive. To calculate break-even you need to distinguish between fixed costs (those that do not vary with sales: rent, insurance, depreciation, base wages of permanent staff, fixed utility charges) and variable costs (those that rise in proportion to sales: mainly the cost of raw materials, or food cost).
Break-even is reached when total contribution margin (the difference between sales and variable costs) exactly equals fixed costs. In practice, a restaurant with monthly fixed costs of €15,000 and a contribution margin ratio of 65% (that is, of every euro sold, €0.65 is contribution margin) needs to sell €15,000 / 0.65 = €23,077 a month to break even. If the average spend is €25, that is 923 covers a month or about 31 covers a day (assuming 30 days of opening). Every cover above that figure is pure profit (after covering the variable cost of the dish).
Break-even analysis is especially useful for judging whether a new restaurant is viable, analysing the impact of changes to fixed costs (a new lease, taking on staff), modelling scenarios with price or cost increases, and setting minimum sales targets for the team.
Break-Even Point (€) = Fixed Costs / Contribution Margin Ratio
Calculating break-even requires two figures: total fixed costs for the period and the contribution margin ratio (which is 1 minus the variable cost ratio or, put another way, the percentage of each euro of sales left after paying variable costs). If your monthly fixed costs are €18,000 and your average variable cost (mainly food cost) is 32% of sales, your contribution margin ratio is 1 – 0.32 = 0.68 (68%). The break-even point is €18,000 / 0.68 = €26,471. You need to turn over €26,471 a month to cover all your costs.
To express it in covers, divide by the average spend. If your average spend is €22, you need 26,471 / 22 = 1,203 covers a month, or about 46 covers a day (opening 26 days). You can also express break-even per day: if you open 26 days a month, you need to take an average of 26,471 / 26 = €1,018 a day to cover your costs.
You are assessing whether to open a 40-seat restaurant. You project the following monthly fixed costs: rent €3,500, base wages €9,000, Social Security €2,700, fixed utilities €600, insurance and sundries €400. Total fixed costs: €16,200. You estimate a food cost of 30% and an average spend of €24.
The contribution margin ratio is 70%. The break-even point is 16,200 / 0.70 = €23,143 a month, equivalent to 965 covers (23,143 / 24). If you open 26 days a month, you need to serve 37 covers a day. With 40 seats, that means average occupancy of 93%...
clearly not enough if you only do one sitting. Options: add a lunch service (doubling your sittings), cut fixed costs (negotiate the rent), increase average spend (adjust the menu) or reduce food cost (optimise your recipe costings). Without reaching break-even, the business is unviable from day one.
The break-even point is the red line between survival and closure. Any restaurant that does not know its break-even is flying blind, without knowing how much it needs to sell each day to cover its costs. This metric is essential in many situations: before opening (is the project viable with this rent and these costs?), when negotiating contracts (what does a rent increase do to my break-even?), when designing the menu (what average spend do I need for break-even to be achievable?), when hiring (how much extra do I need to sell to cover a new salary?) and when setting sales targets (the team needs to know the minimum number of covers to serve each day). Break-even analysis also lets you calculate your margin of safety: if you turn over €35,000 and your break-even is €25,000, you have a margin of safety of €10,000 (28.5%) before you start making a loss.
The bigger your margin of safety, the more resilient your business is to falls in sales from the low season, economic downturns or the unexpected.
Zindra automatically calculates your break-even point from the fixed costs you have set up and the real contribution margin of your sales. The dashboard shows how far you are from break-even each day and alerts you if your sales pace suggests you will not reach it by the end of the month.

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.
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.
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.
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.
