A vehicle does not show up at the planned time. The mechanic is available, the lift is booked and the parts may already be waiting on the shelf. For an auto repair garage, the cost of a missed appointment is not limited to the absent revenue: you also need to measure the unused workshop time, the tied-up parts and the follow-up work. There is no national no-show rate that the sources consulted allow us to confirm for French garages as a whole. L'Argus nevertheless reports that the phenomenon varies with the context and can reach 20% during private sales or…

A restaurant owner systematically offers a coffee to loyal customers, serves a house aperitif at the start of the service and brings bread with the table setting without billing it. In a restaurant, these gestures improve the welcome, but they also represent a cost item that rarely shows up on an invoice. Added up over a year, they can reduce the margin rate and increase the revenue needed to reach the break-even point. The working assumptions for a restaurant The figures below are working assumptions, to be adapted to your establishment. They are not market averages. The restaurant opens six…

A vehicle comes back to the workshop after a brake pad replacement: the customer reports a noise and asks you to check the job. In an auto repair garage, this rework can tie up staff, parts and a courtesy car, while disrupting planned appointments. To understand its real cost in 2026, here is a fully hypothetical example, priced line by line in euros excl. VAT. The calculation assumes the noise is linked to the initial repair and that the garage therefore redoes the work without charging the customer. A return to the workshop is not automatically a free rework, though:…

For a traditional sit-down restaurant, an unannounced absence or last-minute cancellation is more than an empty chair. It can mean unrealised revenue, ingredients already prepared, and labour scheduled for covers that never arrive. The following hypothetical example shows how to measure the impact without confusing lost sales with committed costs. Start with the number of covers lost Assume your traditional sit-down restaurant operates 26 evening services per month. During each service, 3 covers are lost because of an unannounced absence or a last-minute cancellation. The monthly calculation is: 26 evening services × 3 absent covers = 78 covers not served…

How much does a four-tyre job really earn in an auto repair garage? To find out, look beyond the customer’s invoice: include the tyre purchase, valve, balancing weights, eco-contribution and the mechanic’s time. This worked example shows what remains after those direct costs, and why that amount is not the garage’s final profit. Hypothetical working assumptions: one four-tyre job The figures below are hypothetical working assumptions for a light vehicle. They are not market averages. All selling prices and costs are in euros and, unless stated otherwise, are € excl. VAT. Per tyre: item Customer charge or purchase cost Calculation…

For an auto repair garage, two pricing levers deserve separate attention: the hourly rate charged to customers and the margin rate applied to parts. This hypothetical 2026 example shows how to calculate both using explicit labour, workshop, and parts costs. Every figure is an assumption for teaching purposes and can be recalculated line by line. The auto repair garage hourly rate: start from the real hourly cost The first mistake is to divide annual payroll by the number of hours an employee is paid and treat the result as the minimum customer rate. An auto repair garage must distinguish between…

Running a hair salon profitably requires more than filling appointment slots. You need to know what each service contributes after labour, products, payment processing fees and fixed costs. This guide uses a fully hypothetical example to show how to calculate a salon service’s margin, set a sustainable price and determine how many services you need each month to cover your costs. For sector context, consult UNEC, “Chiffres clés 2025” (2024 data) and the CNEC sector barometer, consulted on 20 August 2026. No sector average is used in the calculations below: every figure is a hypothetical assumption. Which tool should you…

For an auto body and paint shop, a full respray and a bumper repair can generate very different results even when both jobs appear well priced. The difference comes from the real cost of labour hours, paint products, consumables, energy, waste treatment, parts and time spent preparing quotes that are never billed. This guide uses a fully hypothetical, recalculable example in euros to show how you can calculate the margin rate of each job without hiding costs. It focuses on the profitability of individual repairs, not on calculating a break-even point. The two indicators to distinguish Before pricing a job,…

A customer calls you about a leaking mixer tap. You plan 1.5 hours on site, a few fittings, a call-out and a small part. A few weeks later you carry out the annual service of a boiler under a maintenance contract. The revenue looks comparable, yet the profitability can be very different. So how do you calculate the margin of a plumbing and heating business in 2026? You need to separate the one-off repair, the equipment replacement and the maintenance contract, then bring in copper, spare parts, productive labour, the van and the fixed costs of your company. To test…

In 2026, the break-even point of a food truck in France does not depend on the price shown on your menu alone. To know how many meals you need to sell each day, you have to account for ingredients, packaging, labour, the pitch fee, energy, fuel and every other fixed cost. Below is a fully hypothetical, recalculable example you can use to set your daily target. The daily break-even formula For a food truck, the calculation takes three steps: Add up your monthly fixed costs. Work out the contribution margin per meal. Divide the fixed costs by that margin, then…
