A restaurant's fixed costs are the expenses that stay relatively stable even when sales change, such as rent, insurance, licences, software or part of the core staff.
Fixed costs in a restaurant are the set of expenses the business has to bear even if it sells little, has empty tables or even closes on some days because of low demand. That does not mean they can never change, but that they do not vary directly with each dish sold or each cover served. Rent, certain insurance policies, licences, software subscriptions, maintenance contracts, the gestoría (the outsourced accounting and payroll firm most Spanish restaurants use), depreciation, financing and part of the core staff are common examples. Unlike variable costs, which grow as sales or production increase, fixed costs create a minimum monthly burden the restaurant must cover before it starts generating profit.
That is why they are a key part of the break-even point: the higher the fixed costs, the more sales the business needs in order not to lose money. In hospitality, many management mistakes happen when people look only at food cost and ignore the fixed cost structure. A dish may have a good contribution margin, but if the restaurant carries disproportionate rent, heavy debt or too many administrative costs, overall profitability will still be weak. It is also worth distinguishing between pure fixed costs and semi-fixed costs.
For example, a full-time head chef is usually fixed within the normal range of activity; but if the restaurant opens an additional sitting, it may need to hire more staff and that cost will step up to a new level. Understanding this difference leads to better decisions about opening hours, capacity, bookings, delivery, events, investment and pricing. A healthy restaurant does not try to eliminate all fixed costs (some are necessary to operate with quality), but to size them according to its real ability to generate margin.
Total fixed costs = Sum of expenses that do not depend directly on sales volume
To calculate monthly fixed costs, add up all the expenses that remain even when the restaurant is less busy: rent, insurance, subscriptions, licences, accounting fees, software, maintenance, loans, depreciation and core staff. You can then use the total to calculate the break-even point: break-even sales = Fixed costs / Contribution margin percentage. If a restaurant has €28,000 of fixed costs a month and a contribution margin of 65%, it needs 28,000 / 0.65 = €43,077 of sales excluding VAT to cover its costs and start generating profit. If the contribution margin falls to 55%, the break-even point rises to €50,909.
A restaurant turns over an average of €70,000 a month excluding VAT. Its fixed costs are: rent €7,500, core salaries €18,000, insurance and licences €900, software and POS €450, accounting fees €350, maintenance €800, equipment depreciation €1,200 and other fixed costs €1,000. Total: €30,200 a month. Its contribution margin after ingredients, drinks, packaging and commissions is 62%.
The break-even point is 30,200 / 0.62 = €48,710. That means the first €48,710 of sales go towards covering overheads; operating profit only starts after that. If in August it decides to close at lunchtime on weekdays, it is not enough to look at the savings in variable staff costs: it must check whether the lost sales stop covering a sufficient share of the fixed costs.
Fixed costs matter because they define the restaurant's minimum financial pressure. A business with low fixed costs can better survive quiet seasons, shifts in demand or rising ingredient prices. One with high fixed costs needs consistent volume, occupancy and average spend to stay afloat. Analysing fixed costs helps you negotiate rent, decide whether to open longer hours, evaluate investments, set prices, design sales targets and understand why a full restaurant may not be profitable.
It also prevents misleading decisions: a promotion may look good because it covers food cost, but if it does not bring in enough contribution margin to cover the fixed structure, it only adds work without improving profit. Managing fixed costs is not about cutting indiscriminately; it is about aligning the structure of the business with its real ability to sell and generate margin.
Zindra lets you classify expenses as fixed, variable or semi-fixed and cross them with sales, purchases, staff and inventory. That way you can calculate your break-even point, see how much margin you need each month, compare sites or periods and understand whether the problem lies in variable costs, the fixed structure or sales volume.

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.
Cash flow in a restaurant is the movement of money in and out of the business. Managing cash well is vital for the restaurant's survival, even if it is profitable on paper.
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.
Occupancy cost covers all the expenses tied to the restaurant's physical premises: rent, property tax, insurance, service charges and structural maintenance. It should stay between 8% and 12% of revenue.
A restaurant's variable costs are the expenses that change directly or proportionally with the level of sales or production, such as ingredients, drinks, delivery commissions or consumables used per service.
