A daily rate covers the time the vehicle is away. It does not cover what happens to it in that time. A van that comes back after a weekend with 1,400 extra miles on it is closer to its next service, its next set of tyres and a lower resale value. A mileage limit is how you price that fairly: low-mileage customers stop subsidising high-mileage ones.
1. Three models and who they suit
| Model | How it works | Suits |
|---|
---|---|---
| Daily allowance | a set distance per hire day, added up across the hire | cars and vans on short hires |
|---|---|---|
| Allowance per hire | a fixed block of mileage for the whole term | long-term hires, business customers |
| Unlimited mileage | no limit, higher daily rate | holiday and long-distance customers; a strong selling point |
Most rental businesses combine the first and third: a base price with an allowance and a supplement for unlimited mileage. The customer chooses and does not feel restricted.
One decision matters more than the rest: the allowance is pooled across the hire, not counted day by day. Someone hiring for three days with 200 miles per day has 600 miles, and it does not matter if most of it is driven on one day. Day-by-day counting is hard to evidence, hard to explain and feels like a trap.
2. How much mileage to include
Start from how your customers actually drive. If your handover records carry odometer readings, you already have the data: average distance per hire day and how it spreads. Set the allowance so that the large majority of ordinary hires fit inside it — say four out of five. An allowance that half your customers exceed is not a limit but a hidden surcharge, and they will treat it as one.
Typical allowances vary widely by market, vehicle class and location; an airport branch sees very different mileage from a van hire business serving house moves. Treat any figure you see elsewhere as an orientation and check it against your own records.
3. The excess mileage rate
The rate should cover what a mile really costs you, plus a reasonable margin. Cost per mile includes:
- depreciation attributable to mileage,
- servicing and maintenance spread over the service intervals,
- tyres,
- on long-term hires, any insurance element tied to annual mileage.
Fuel does not belong in the rate if you hire on a full-to-full basis. How to build the whole price list from costs is covered in How to price equipment rentals.
Keep the rate simple — one figure per vehicle category, quoted the way your market expects prices to be shown to consumers (tax rules differ by country). Tiered rates by mileage band look fair on paper, but nobody can work them out at the return desk, and that is where trust is lost.
4. What the agreement must say
An excess mileage charge is a contractual claim. If it is not in the agreement the customer accepted, you have nothing to charge, even if the limit is on your website. The agreement should state:
- the allowance and how it is counted (pooled over the whole hire),
- the excess rate,
- what happens on extension — the allowance increases pro rata,
- what happens on early return — usually no reduction, but say so,
- the odometer reading at collection as the starting point, by reference to the handover record,
- a provision for odometer failure or suspected tampering.
The clauses that decide disputes in general are covered in Rental agreement clauses that matter. For online bookings, the customer must see the allowance and the rate before paying, not for the first time at collection. Consumer-protection rules on price transparency differ by country; check what applies to you.
5. The odometer in the handover record: a photo, not just a number
Mileage disputes are rarely about the rate. They are about the starting figure. So:
1. At collection, write the odometer reading in the handover record and photograph it, with the fuel gauge in the same shot. A time-stamped photo beats a handwritten number.
2. The customer signs the record, confirming the reading.
3. Do the same at return. The difference, minus the allowance, times the rate, is the charge; show the customer the sum on the spot.
4. Settle it straight away, ideally against the deposit, and issue a receipt.

6. How to talk about the limit
A mileage limit only causes trouble when the customer did not know about it. Three habits prevent that:
- Say it out loud at collection, even though it is in the agreement. "You have 600 miles for the whole hire; each extra mile costs this much."
- Ask where they are going. Someone heading across the country should be offered unlimited mileage before they leave, not a bill when they come back.
- Show the sum at return. Two readings from the record, the allowance, the rate. Transparency is cheaper than a complaint.
A customer who knew in advance pays the excess without comment. A customer who first heard of the limit at return writes a review.
Where Flotello fits
In Flotello the mileage limit is set per vehicle: maximum distance per day and the price per extra kilometre. The odometer reading is captured in the handover record at collection and return, with a time-stamped photo, and the distance is calculated from the two records — staff see the excess and the charge at return without doing the arithmetic. Handover records are explained in the help centre, plans on the pricing page, and you can try it free for seven days after registration.
