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 kilometres driven or a possible cleaning fee. Each item is listed separately on your final invoice with description, quantity and unit price, so you can see exactly how the total is made up.
Common reasons
Extension or late return – additional rental days (e.g. "extra days", "Flexi late return")
Extras added at the branch – e.g. upgrades, additional driver, child seat, protection package
Refuelling or recharging fee – if the vehicle wasn't returned fully refuelled or fully charged
Additional kilometres – if the booked mileage package is exceeded, each additional kilometre is charged
AdBlue or consumption-based costs – 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 km), unit price and gross 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 you'll find what each line means and where it comes from.
Typical 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 – fully comprehensive/theft cover, excess reduction, all-inclusive components (e.g. interior cover, mobility service) – charged per day
Extras – additional driver, sat-nav, child seat, winter tyres
Registration / road usage fee – the name and amount vary by country of rental
Additional kilometres – charged per km 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 – e.g. "Flexi late return"
One-way fee – if the return location differs from the pick-up location
Taxes – insurance tax and VAT (rate varies by country)
Where the amounts come from
Rates and booked extras come from your signed rental agreement. Refuelling/recharging fees, additional kilometres and late return charges result from the return check.
Note: Fines and damage charges are not billed via the final invoice but separately – you'll receive a dedicated notification from SIXT if applichible.
