The short answer
Price self-drive hires with a grace period that works as a threshold, not a deduction: a return inside it is free, a return beyond it is charged for every started extra unit. Charge extra distance only when a hire has an allowance, a rate and both odometer readings, and never count a security deposit as revenue.
Self-drive hire looks simple until the first late return. Was 20 minutes late free? Is two hours and ten minutes two hours or three? Who pays when the car comes back well over its distance allowance? Clear rules, applied the same way every time, save arguments at the counter and money at month end.
How should overtime be charged on a late return?
Set a grace period, such as 30 or 60 minutes, and use it as a threshold:
- Returned within the grace period: no overtime.
- Returned beyond it: charge for the whole extra time, rounded up to the next hour or day.
So with a 30-minute grace on hourly overtime, a car 15 minutes late costs nothing extra, while a car 90 minutes late is charged two extra hours, not one. This keeps small delays friendly while making real lateness predictable.
How should extra distance be charged?
Only charge for extra distance when three things are true:
- The hire has a distance allowance.
- The hire has a rate per extra unit of distance.
- You have both odometer readings, at handover and at return.
If any is missing, bill no excess. Unlimited distance is a common and valid offer, and a missing reading should never quietly turn into a charge. The allowance is simplest as one total for the whole hire rather than per day.
A worked example
Say a two-day hire includes an allowance of 400 and charges 0.25 for every unit of distance over it, in whichever unit your agreement uses.
- Odometer at handover: 48,210
- Odometer at return: 48,790
- Distance driven: 580
- Over the allowance: 580 − 400 = 180
- Extra-distance charge: 180 × 0.25 = 45, in your currency
The sum works the same whichever unit you use. What matters is that the allowance, the rate and the odometer all use one unit, and that the agreement says which.
What about early returns?
An early return usually does not earn an automatic refund; the car was reserved for the full period. If you choose to give money back as a goodwill gesture, adjust the rental line before you issue the invoice. Our free car rental invoice template has separate lines for the hire, overtime and extra distance.
How should security deposits be handled?
A deposit protects you against damage and unpaid charges. It is not revenue: you are holding it and will normally return it. Record it on the hire, mention it on the invoice as a note, and keep it out of your sales figures.
Record the evidence at both ends
Every rule above depends on facts from handover and return: the times, the odometer readings, and photos of the car’s condition. Recording them on the spot, every time, is what makes the charges defensible. If your bookings are still in a spreadsheet, our car rental booking spreadsheet has columns for the odometer out and in, and works out the distance driven.
Odobase self-drive hire, switched on in every new Odobase account, applies these rules automatically: grace periods as thresholds, overtime rounded up, extra distance charged only with an allowance and a rate, and deposits kept out of revenue. See how it fits a car rental business.

Frequently asked questions
Should a grace period be deducted from the late time?
No. Use it as a threshold. If a customer is inside the grace period, charge nothing; once they are beyond it, charge the whole late time, rounded up to the next unit. Deducting the grace period invites customers to treat it as free extra time every time.
How much should an hour of overtime cost?
Start from your daily rate. An hourly overtime rate of a quarter to a third of the daily rate is common, with a cap at one extra day, so a car returned many hours late is never charged more than a full day.
Is the distance allowance per day or per hire?
Either can work, but state it clearly on the agreement. Applying one total allowance to the whole hire is the simplest to explain and to check at return.
Which unit should extra distance be charged in?
Use the unit your odometers and your rental agreement use, and state the allowance and the rate in that same unit. The arithmetic is identical whichever unit it is, as long as the allowance, the readings and the charge all agree.
Is a security deposit income?
No. A deposit is money you are holding and will usually return. Record it on the hire and mention it on the invoice, but do not count it as revenue.
