What is restaurant profitability?
A restaurant's break-even point is the moment when revenue covers all of your costs: raw materials, payroll, rent, energy, fixed charges. Below it you lose money; above it you start making a profit.
So profitability isn't just about being 'full every night'. A restaurant can be packed and still lose money if its food cost slips or its schedules don't match real footfall. Conversely, a half-full but well-run venue can post a healthy margin.
In Réunion, that break-even point is mechanically higher: your purchases start from a higher price than on the mainland. Regular tracking of your indicators isn't a luxury, it's what separates a restaurant that runs from one that makes money.
How to calculate your restaurant's profitability
Two levels of reading complement each other: the dish and the venue.
- Per-dish profitability: (selling price − food cost of the dish) ÷ selling price. That's your gross margin per plate.
- Overall profitability: (total sales − total costs) ÷ total sales. That's the big picture.
But real steering comes down to three ratios, expressed as a percentage of revenue. These are the ones to track, ideally every week:
28–35%
Food cost, often aimed below 30%
30–35%
Fully loaded payroll
< 65%
Prime cost (food + labour) ceiling
If 'food + labour' (the prime cost) stays above 65% of revenue, what's left (rent, energy, charges) rarely leaves enough to live on. The net margin of a traditional restaurant is often between 5 and 10%, sometimes less. Every point counts.
The local reflex
Calculate your ratios with your real Réunion purchase prices, not the figures from 'mainland' recipe sheets. A theoretical 28% food cost can actually run at 33% once imports and octroi de mer are included.
Food cost in Réunion: a built-in handicap
This is where the island changes everything. Food cost is your biggest expense, and in Réunion it starts with a structural disadvantage that 'mainland' management advice ignores.

Octroi de mer
a tax the mainland doesn't have
In practice: most of what goes onto your plates has travelled thousands of kilometres. Sea freight, delays, supply shortages, and a starting price already inflated. The octroi de mer is added to VAT on a large share of imported products. As a result, food prices are on average 37% higher than on the mainland.
On top of that comes seasonality: footfall and cash flow swing from full to empty between high and low season. Tuning purchasing and payroll to that rhythm demands a discipline mainland regularity never requires.
The good news: these constraints can be managed. Local sourcing where possible, recipe sheets recalculated at real prices, waste managed to the gram, a menu built around products you control. That's exactly what a food cost audit is for.
Which type of restaurant is most profitable in Réunion?
No format is profitable 'by nature', it all depends on management. But each model has its orders of magnitude, which imports push upward on the food side.
- Fast food & street food: food cost often 30–35%, but volume and pace drive the margin. Lighter labour, organisation is king.
- Bistronomy & traditional dining: food cost manageable around 28–32%, but heavier payroll (service, kitchen). Margin is won on the menu and consistency.
- Sushi & imported fresh products: high food cost, very sensitive to imports; profitability is earned to the gram, on cutting and waste.
- Snack bars, food trucks, takeaway: lower fixed costs, lower break-even, a relevant format against the island's property costs.
What really matters
The most profitable format is the one whose levers you control: a held food cost, payroll matched to footfall, and a menu designed for margin. A well-run snack bar beats a poorly steered fine-dining restaurant.
Opening a restaurant in Réunion: what changes
An opening project follows the same steps as anywhere (market study, forecast, legal status, location), but a few local realities weigh in from the start.
- The forecast must factor in a higher food cost and seasonal cash-flow variability, or it will underestimate the break-even point.
- Sourcing is prepared upstream: identifying local producers, wholesalers and reliable import channels avoids the shortages that break a menu.
- Location and format are chosen around property costs and the area's tourist flows (west coast, Saint-Denis, south…).
- Working capital needs are higher: between supply lead times and the low season, a comfortable cash cushion is wise.
A forecast built on the island's real figures (not national averages) is the best safeguard before opening.
How to improve your restaurant's profitability
Improving profitability isn't 'sell more' at any cost: it's gaining on every lever, starting with the ones that pay off fast.
- Rework food cost: recipe sheets at real prices, supplier negotiation, waste reduction, local sourcing when competitive.
- Make the menu work (menu engineering): highlight high-margin dishes, adjust a few prices, drop what doesn't sell.
- Match payroll to footfall: schedules tuned to real traffic avoid hours lost in quiet services.
- Track indicators weekly: a drifting food cost or prime cost can be recovered if spotted early, not at year-end.
On a small business, every point of margin counts double and shows fast. Two points of food cost recovered on a restaurant with €30,000 monthly revenue is around €600 kept every month.
Frequently asked questions about restaurant profitability
What's a good food cost for a restaurant in Réunion?
You generally aim for a food cost between 28 and 35% of revenue. In Réunion, imports and the octroi de mer push this ratio upward: the goal is to hold it as close to your target as possible despite the surcharge, by working on recipe sheets, sourcing and waste.
Why can a restaurant be packed and still lose money?
Because revenue says nothing about margins. If food cost slips, if payroll isn't matched to footfall, or if the menu highlights the wrong dishes, a full restaurant can still run at a loss. Tracking the ratios is what reveals the problem.
How long before you see results?
Some levers (pricing, menu, organisation) are felt within the following weeks. Others, like supplier renegotiation or schedule overhauls, settle over a few months. Regular tracking embeds those gains over time.
Is a profitability audit worth it for a small venue?
Often even more so. On a small business, every point of margin weighs proportionally more and adjustments show fast. An audit adapts to the venue's size and budget.
