Restaurant financial KPIs France 2026: food cost, prime cost, VAT and cash management

Up to date as of 14 May 2026.

A profitable restaurant is not managed from the annual profit line. In Paris, where rent, payroll and food costs together represent 85 to 95 % of revenue in many configurations, weekly — or even daily — monitoring of a handful of key indicators determines whether an establishment survives. This article sets out the sector-specific KPIs that genuinely matter, with reference benchmarks, applicable legal rules and the trade-offs we handle day-to-day at Cabinet Hayot Expertise in Paris.

Definition and calculation method#

Food cost measures the ratio of cost of goods consumed to net (ex-VAT) sales. The exact formula is:

Food cost (%) = (Opening stock + Purchases − Closing stock) / Net sales × 100

The most common error is dividing by gross (VAT-inclusive) revenue. The 10 % VAT rate applicable to on-premises restaurant sales (Article 279 b quater of the French Tax Code, FTC) artificially inflates the denominator and understates the true cost ratio. All calculations must use ex-VAT figures.

Benchmarks by menu category#

An overall target of 28–32 % of net sales is appropriate for mid-range plated dining. That aggregate figure masks significant variation:

• Meat and fish: food cost often 35–45 % due to high purchase prices. Menu pricing must compensate.
• Cold starters and soups: lower food cost around 20–25 %, which balances the overall margin.
• House-made desserts: food cost 15–20 %, a strong margin lever when production is controlled.
• Non-alcoholic beverages: beverage cost 8–15 %, very favourable.

In files we handle in Paris, a global food cost above 35 % without a premium positioning rationale is a systematic warning signal. The most common causes: poor portion control, untracked wastage, undetected internal theft, and purchases outside agreed supply frameworks.

Meat and fish stock rotation#

A meat or fish stock exceeding 7 days generates waste and sanitary risk. The target is 2–4 days depending on activity volume. Weekly cross-referencing of delivery notes against a rolling inventory is the minimum procedure. Establishments that take a physical inventory only at year-end cannot manage their food cost: they record it after the fact, too late to correct it.

Differentiated VAT: 5.5 %, 10 % or 20 %#

French beverage VAT in a restaurant context involves three rates, creating mis-classification risk in EPOS systems:

• 5.5 % (FTC art. 278-0 bis A): take-away sales of non-alcoholic beverages and water, unprocessed food products sold without table service.
• 10 % (FTC art. 279 b quater): non-alcoholic beverages consumed on premises in a restaurant or café.
• 20 %: alcoholic beverages without exception — on premises, take-away or direct retail. No exception.

The BOFiP (BOI-TVA-SECT-80) details the rules for mixed situations (cocktails with and without alcohol, wine by the glass vs. retail bottle). A poorly configured EPOS system systematically applies the 10 % rate to all beverages, under-declaring VAT on alcohol sales. This issue is regularly identified in French tax audits of restaurants.

Beverage cost and gross margin#

A beverage cost of 18–22 % on net beverage sales is the standard target. Wines by the glass and cocktails allow substantially higher gross margins than packaged drinks. The wine list often represents 25–35 % of total net sales in a mid-range Parisian restaurant: its management is strategic, not incidental.

Definition and critical threshold#

Prime cost adds food cost (goods cost) and labour cost (fully loaded payroll including casual staff, agency workers and HCR employer social charges) as a percentage of net sales. A prime cost above 65 % leaves less than 35 % of net sales to cover rent, energy, insurance, maintenance, franchise fees, management costs and net profit. In Paris, where rent often represents 8–15 % of sales, a prime cost of 68–70 % is structurally loss-making.

Labour-to-sales ratio: the HCR constraint#

The national HCR collective agreement (IDCC 3292, 30 April 1997 and amendments) sets minimum wages by qualification, overtime supplements, split-shift compensation and meal allowances. The target labour-to-sales ratio is 30–35 % for a brasserie or bistronomic restaurant, rising to 38–42 % for fine dining with a full brigade.

HCR employer charges have a specific feature: the general payroll tax reduction on wages up to 1.6 times the minimum wage (the Fillon reduction, Article L241-13 of the Social Security Code) applies in full, and sector-specific supplementary health and pension contributions under the HCR agreement add to standard charges. The real employer cost must be modelled employee by employee, not estimated as a flat rate.

Tax-exempt tips: current status (to be confirmed for 2026)#

The 2022 Social Security Financing Act introduced an exemption from social contributions and income tax on tips received by client-facing employees in the HCR sector. This mechanism, initially for 2022 and 2023, was subsequently renewed. Its validity for the 2026 financial year must be confirmed against an up-to-date BOFiP or URSSAF source before application. Cabinet Hayot Expertise monitors renewal texts each year when processing the January payroll closing.

Productivity: sold hours vs. paid hours#

This ratio measures planning efficiency: hours worked on service / hours contractually paid (including split-shift breaks, meetings and set-up time). A target of 1.3 to 1.5 means that for every 10 hours paid, 13 to 15 hours are directly productive on service. Below 1.1, the planning structure generates excessive compensated dead time. Calculating this requires time-tracking software or at minimum a weekly clocking table.

The 10 % rate: the default for on-premises dining#

Article 279 b quater FTC subjects the sale of food and non-alcoholic beverages consumed on premises in catering establishments to the 10 % rate. This is the default for virtually all sales in a traditional restaurant. The rate also applies to table service, bread and dishes served on premises even if the same item is sold to take away.

The 5.5 % rate: reserved for take-away and delivered food#

Article 278-0 bis A FTC reserves the 5.5 % rate for food products sold to take away or for delivery, without associated table service. Practically: sandwiches, packaged salads, take-away menus, non-alcoholic beverages in sealed packaging. As soon as there is any element of on-premises service — even partial — the rate reverts to 10 %.

The most costly classification errors#

In French tax audits targeting Parisian restaurants, Cabinet Hayot Expertise regularly sees three recurring errors:

1. Applying 5.5 % to non-alcoholic beverages consumed on premises (should be 10 %).
2. Applying 10 % to alcoholic beverages sold to take away (should be 20 %).
3. Blending rates on combined menus — a set menu including a glass of wine billed at a single 10 % rate when the alcoholic element should be isolated at 20 %.

A misconfigured EPOS system does not correct these errors automatically. VAT settings must be reviewed with the accountant when installing or changing the system.

Average ticket: a positioning indicator as much as a performance measure#

Average ticket (ex-VAT) = net sales / covers served. This indicator must be read in the context of the pricing strategy and also the basket composition: alcohol-to-food ratio, dessert take-up rate, coffee ordering frequency. A drop of 5 % or more over four consecutive weeks without a seasonal explanation is a warning signal requiring analysis before it becomes structural.

Occupancy rate and table turns#

The occupancy rate measures the commercial capacity being utilised. A target of 70–80 % across open services is appropriate for a Parisian restaurant. Table turns (how many times a given table is occupied per service) is a complementary KPI: 1.5 to 2.5 is the norm. Above that level, the risk is degrading the guest experience. Below 1.2, capacity is underused.

Both indicators are tracked via reservation software (TheFork, Resy, OpenTable) cross-referenced with the daily EPOS close-of-day report. Integrating them into a weekly dashboard — configured on Pennylane or Finthesis depending on the client setup — is sound practice for establishments with more than 40 covers.

Digital KPIs: Google reviews and reservation conversion#

The conversion rate from Google My Business profile views to actual reservations is an underrated operational KPI. A Google score below 4.2 stars begins to weigh on occupancy, particularly for restaurants without dominant walk-in traffic. Responding to negative reviews and soliciting positive reviews post-meal (via QR code or automated SMS) are operational levers, not marketing gimmicks.

Doggy bag, biowaste sorting and single-use plastics#

France's AGEC Act (Law No. 2020-105 of 10 February 2020) introduced several obligations for commercial restaurants:

• Mandatory doggy bag: a take-away container must be made available to customers for unfinished meals, phased in by establishment size. The container cost must be included in food cost or general expenses.
• Separate biowaste collection: separate sorting and collection of food and vegetable waste is required with progressively tightening thresholds. Contracts with a biowaste collection provider must be invoiced and traceable.
• Reduction of single-use plastics: cups, cutlery and plastic straws are banned. Replacements (cardboard, starch-based) cost 2 to 5 times more per unit.

These AGEC costs form part of operating expenses and must appear in the budget. Precise 2026 thresholds and implementation schedules should be verified with ADEME or the competent regional environmental authority.

HCR collective agreement IDCC 3292 and payroll particularities#

The HCR collective agreement (IDCC 3292) presents several features that complicate payroll and generate frequent errors:

• Meal benefits in kind: flat-rate valuation per meal taken at the workplace, set by the sector and periodically revised (verify with URSSAF for the current rate).
• Split shifts and rest breaks: unpaid break periods between two services have specific conditions, with conventional compensations depending on duration.
• Overtime supplements: the HCR sector provides specific enhanced overtime rates. General-purpose payroll software does not always apply them correctly without dedicated configuration.
• Casual staff and fixed-term usage contracts (CDD d'usage): the HCR sector can use fixed-term usage contracts for certain job categories. The list of eligible roles and renewal conditions must be strictly observed.

The DSN (monthly social declaration) must be filed by the 5th or 15th of the following month depending on headcount. Any error in the collective agreement code in the DSN generates pension entitlement anomalies for employees and URSSAF adjustment demands.

The restaurant cash gap: a different dynamic from other sectors#

A restaurant collects revenue primarily in real time (cash, card): its working capital requirement is structurally more favourable than an industrial SME's. But this apparent ease masks a real risk: daily cash balances can conceal genuine negative profitability if future charges (rent, month-end payroll, stock replenishment) are not provisioned.

The method we recommend at Cabinet Hayot Expertise in Paris: a daily dashboard separating gross receipts, VAT collected to remit, payroll provisions, quarterly rent provisions and variable outgoings. This dashboard is built in a week's work on Pennylane by connecting the EPOS software.

Seasonality and precautionary cash reserve#

A Parisian restaurant typically sees revenue variations of 30 to 50 % between January–February and June–July depending on its location. The precautionary cash reserve must cover at least 2 months of fixed, non-compressible charges (rent, base payroll, insurance). Restaurants that reach September without this reserve face cash pressure at the first unexpected event.

The three trade-offs we encounter most often#

Trade-off 1 — Food cost vs. product quality. A Paris restaurant owner who upgrades sourcing (Label Rouge, short-circuit supply, seasonal AOP products) sees food cost rise. The trade-off is to verify whether the higher average ticket compensates. The answer is yes — provided product-origin communication is visible and consistent with the room's pricing positioning.

Trade-off 2 — Payroll vs. service quality. Cutting casual staff to reduce the labour ratio often produces the opposite effect: lower guest satisfaction, a drop in the Google score and lower occupancy. The right lever is productivity (improving sold vs. paid hours), not raw headcount compression.

Trade-off 3 — Revenue growth vs. prime cost. Opening Sunday evenings or launching a brunch service increases sales, but can degrade the prime cost if occupancy for the additional services falls below the break-even threshold. We calculate the marginal break-even point before recommending opening new service slots.

The underestimated risk: unreconciled alcohol VAT#

In establishments where alcoholic beverages represent 20 % or more of sales, a VAT classification error (20 % instead of 10 %) sustained over 12 months can generate a VAT reassessment of several tens of thousands of euros, including interest and penalties. This risk is underestimated because the EPOS system displays a total sales figure without a readable VAT breakdown. Reconciling the monthly EPOS close-of-day report with the VAT return (CA3) is the minimum control procedure we perform on every restaurant file at Cabinet Hayot Expertise in Paris.

2026 watchpoints#

• Tax-exempt tips: renewal of the LFSS 2022 mechanism for 2026 must be confirmed.
• E-invoicing: restaurants above the ETI revenue threshold must issue e-invoices from 1 September 2026; SMEs and micro-enterprises must be able to receive e-invoices from that date and must issue them from September 2027 (Decree No. 2024-1098 of 4 December 2024). Connecting the EPOS system to a licensed PDP platform is a project to start now.
• AGEC: biowaste sorting thresholds and 2026 packaging obligations should be confirmed with ADEME.
