The method: floor price = cost of ownership ÷ utilisation rate
Most rental companies set their price by looking at the competitor across the street. It is a quick way to inherit other people's mistakes. The right method starts from your vehicle, not from the market:
- Add up what the vehicle costs over a year, whether it is driven or not. Depreciation (purchase price minus resale value, divided by the holding period), insurance, maintenance and tyres, financing interest, parking, telematics, taxes. This is your annual cost of ownership.
- Estimate your utilisation rate honestly. Not the one you hope for: the one you actually see. 365 days × that rate gives the number of days you can really invoice.
- Divide. Cost of ownership ÷ rented days = what each rented day must bring in just to cover your costs. Add the variable cost of a rental day (washing, consumables, time spent) and you get your daily cost price, which is your floor price.
- Add your margin. Recommended price = cost price ÷ (1 − target margin). You divide, you don't multiply: aiming for a 25% margin on revenue is not the same as adding 25% to the cost.
The counter-intuitive part: the utilisation rate weighs more than the purchase price. The same vehicle rented 40% of the time instead of 55% sees its floor price rise by almost 40%. Before cutting your prices to fill the calendar, check that the cut does not take you below the floor: you would be filling your schedule and paying to do it.
The three most common mistakes
- Forgetting depreciation. A vehicle paid for in cash seems free. It is not: it loses value every month, and that loss is a real cost that rentals must cover.
- Reasoning over 365 days. Dividing annual costs by 365 gives a price that covers nothing: the vehicle is not rented every day. You have to divide by the rented days.
- Granting a long-rental discount without checking the floor. −35% on a month is sometimes excellent (the vehicle would have stayed parked) and sometimes ruinous (it takes away days you would have sold at full price in high season). The "check" column in the price list above flags it.
What about seasonality?
This calculator gives an average price over the year. In practice, a rental company works with three seasons: a high season when demand exceeds supply and the price should rise well above the recommended price, a mid season close to the recommended price, and a low season when the goal is no longer margin but utilisation, with one absolute rule: never go below the floor price. The annual average of the three should stay equal to or above the recommended price calculated here.
Frequently asked questions
How do I calculate the rental price of a vehicle?
Add up the vehicle's annual cost of ownership (depreciation, insurance, maintenance, financing, fixed costs), divide it by the number of days actually rented in the year (365 × your utilisation rate), then add the variable cost of a rental day: you get your daily cost price, which is your floor price. The recommended price is that cost divided by (1 − target margin).
What is a good utilisation rate?
There is no official standard. In short-term rental of light vehicles, a range of 45 to 65% is an order of magnitude often quoted by professionals, with wide variations by season, area and vehicle type. The figure that matters is yours: count your rented days over the last twelve months and divide by 365.
Should I include my own pay in the costs?
No, not in this calculation. The costs entered here are the vehicle's. Your pay, your rent, your accountant and your business insurance are overheads: they are funded from the margin generated by the whole fleet. That is why the target margin must be well above zero.
Are the amounts excl. VAT or incl. VAT?
Inputs and results are excl. VAT, because a business recovers VAT on its purchases. The recommended price is also shown incl. VAT at 20%, the standard rate in mainland France, for the price shown to customers. Check the rate that applies to your situation.
Is my data sent anywhere?
No. The calculation runs entirely in your browser: no value you enter is sent to a server. Your email is optional and only asked for afterwards, if you want to receive the links to the tools.
