A higher final invoice usually results from an extension or late return, extras added at the branch, returning the vehicle with less than a full tank or charge, additional mileage or a cleaning fee. Each item is listed separately on your final invoice with a description, quantity and unit price.
Common reasons
Extension or late return — additional rental days (e.g. extra days, late return fee)
Extras added at the branch — e.g. upgrades, additional driver, child seat, protection package
Refuelling or recharging fee — if the vehicle was not returned fully refuelled or fully charged
Additional mileage — if the booked mileage package is exceeded, each additional mile/km is charged
AdBlue — for certain diesel vehicles (e.g. vans), AdBlue is charged per kilometre driven
Cleaning fee — e.g. for smoke odour, pet hair or heavy soiling of the interior
How to read your invoice
Each line shows the description, quantity (days or kilometres), unit price and total. You can compare the items directly with your rental agreement.

A SIXT invoice typically includes rental days, protection packages, extras, fees, any additional charges and the relevant taxes. Each item is listed individually — here is what each line means and where it comes from.
Typical line items
Rental days / extra days — the daily rate of your booked tariff × number of rental days; extra days result from extensions or late returns
Protection package — damage/theft cover and deductible reduction components — charged per day
Extras — additional driver, GPS, child seat, winter tyres
Registration / road usage fee — the name and amount vary by country of rental
Additional mileage — charged per kilometre if your booked mileage package is exceeded
AdBlue — for certain diesel vehicles (e.g. vans), charged per kilometre driven
Refuelling or recharging fee — if the vehicle is returned with less than a full tank or charge
Late return fee
One-way fee — if the return location differs from the pick-up location
Taxes — insurance tax and applicable sales tax (rates vary by country)
Where the amounts come from
Rates and booked extras come from your signed rental agreement. Refuelling fees, additional mileage and late return charges result from the return check
Note: Fines and damage charges are not billed via the final invoice — you will receive a separate notification from SIXT if applicable.
