Sales per square metre measure how much revenue each usable metre of the restaurant generates. They help you see whether the premises, dining room, terrace, bar or kitchen are producing enough revenue to justify their cost.
Sales per square metre in hospitality is a space productivity KPI that relates a restaurant's revenue to the square metres available or in use. It answers a very specific question: how much money does each metre of the premises generate over a period? In hospitality, space is one of the most expensive and limited resources. You pay for it through rent, key money (the premium often paid in Spain to take over a lease, known as traspaso), depreciation, utilities, cleaning, maintenance, air conditioning and opportunity cost.
That is why it is not enough to know that a restaurant turns over a lot; you need to know whether it turns over enough for the size and cost of the premises it occupies. The indicator can be calculated on total floor area, but it is usually more useful to separate the dining room, terrace, bar, kitchen, storage and non-productive areas. A large venue with lots of dead space may have good absolute revenue and weak productivity per square metre.
A small restaurant with high turnover, a good average spend and a well-designed menu, on the other hand, can be more profitable even if its total revenue is lower. This KPI is related to occupancy, RevPASH, table turnover, occupancy cost, average spend and menu engineering. It is also very useful before signing a lease, opening a second site, redesigning the dining room, adding a terrace, shrinking storage or changing the service format. It should not be used in isolation: a fine dining restaurant needs more space per guest and longer table times, while a fast casual concept seeks maximum density and turnover.
The key is to compare the figure with the business model, the location, the price per square metre and the margin each sale leaves.
Sales per square metre = Net revenue for the period / Square metres analysed
To calculate it, divide revenue excluding VAT for a period by the square metres you want to analyse. If you use the total floor area of the premises, you get overall productivity. If you use only the dining room or terrace, you can compare sales areas.
For example, a restaurant that turns over €90,000 a month and has 180 m² in total generates €500/m² a month. If the dining room covers 95 m² and produces most of the sales, the dining room's commercial figure would be €947/m². Always use the same floor-area criterion when comparing months or sites.
A 220 m² restaurant turns over €110,000 a month, equivalent to €500/m². At first glance this seems a good volume, but when it maps its space it discovers that 70 m² are oversized storage and corridors of little use. The dining room covers 100 m², the bar 20 m² and the kitchen 30 m². The bar turns over €18,000 a month, i.e.
€900/m², while the dining room generates €820/m². Storage, by contrast, takes up too much space for the real level of inventory. The team decides to cut slow-moving stock, reorganise the cold rooms, free up 18 m² and add an area of high tables for pre-dinner drinks and tapas. Three months later, revenue rises to €119,000 without any increase in rent or permanent staff, and overall sales per square metre go from €500 to €541/m².
Sales per square metre matter because they connect commercial strategy with one of the hardest decisions in hospitality: the size and use of the premises. Rent that seems reasonable can be expensive if the space does not produce enough sales, and a small venue can be excellent if every metre works hard. This KPI helps you detect oversized dining rooms, under-used bars, unprofitable terraces, excessive storage, layouts that slow down table turnover or kitchens that limit production capacity. It also lets you compare sites of different sizes within a group and assess whether a refurbishment really improves productivity.
Looking at it together with occupancy cost avoids risky decisions: it is not about squeezing in more tables indiscriminately, but about balancing comfort, experience, speed of service, margin and revenue per available space.
Zindra helps you analyse sales per square metre by connecting sales, areas of the premises, occupancy, table turnover, average spend, fixed costs, inventory and reporting. With that data you can see which areas produce most, which time slots waste capacity, whether rent weighs too heavily on sales and which changes to layout, menu or shifts can improve the profitability of your space.

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.
RevPASH (Revenue per Available Seat Hour) measures the revenue generated by each available seat per hour. It is the most complete indicator of a restaurant's operational efficiency and real profitability.
The occupancy rate measures the percentage of available seats actually filled during a service. It is a key indicator of a restaurant's efficiency and the basis for working out its revenue potential.
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.
Table turnover measures how many times each table is occupied during a service. It is a key operational efficiency indicator which, combined with average spend, determines the restaurant's revenue potential.
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 net profit margin is the percentage of sales left as final profit after deducting all costs: ingredients, staff, rent, utilities, commissions, operating taxes and other expenses.
