Car hire excess: what it actually is, what it costs, and the four ways to cover it

CDW (Collision Damage Waiver) and LDW (Loss Damage Waiver) are not insurance policies: they are waivers. The rental company, which owns the vehicle, agrees contractually not to charge you the full cost of the damage, provided you have respected the terms of the hire agreement. What it still charges you is the excess — deductible in American English. Think of it as a liability ceiling: below that ceiling you pay the actual repair cost, above it the waiver takes over.

The deposit is something else again. It is a security hold, either pre-authorised or genuinely debited on a credit card in the main driver's name, usually set at the level of the excess and sometimes topped up with the value of a full tank. It ties up part of your card limit for the whole hire, and often for several weeks after you hand the keys back. Third-party liability, finally, covers damage you cause to others: it is compulsory and included almost everywhere, but it never repairs the car you are driving.

Which gives you the only rule worth remembering here: “insurance included” does not mean “no risk”. It means your maximum exposure is capped. And that cap is the excess.

An excess is not an arbitrary figure: it reflects what an off-the-road vehicle actually costs the rental company in that particular country. Parts prices, local labour rates, shipping delays, claim frequency, theft rates, the density of the repair network — it all feeds the calculation. On a small car hired in Western Europe, the order of magnitude seen in 2026 sits somewhere around 800 to 1,500 euros on a basic package. In destinations where a repair takes weeks — Iceland, Namibia, Botswana, Patagonia, remote islands — the figures climb well beyond that.

Vehicle category weighs just as heavily. A 4x4 kitted out for self-drive (roof tent, long-range tank, reinforced tyres, compressor), a campervan or a premium car costs more to repair, but above all it is a rare unit in the fleet: taking it off the road costs the company a booking it cannot backfill with a compact hatchback. That is why excesses on 4x4s and campervans routinely run into thousands, and considerably more on expedition-spec vehicles.

These amounts shift from season to season, from country to country, and sometimes from branch to branch within the same franchised brand. No figure read in an article, including this one, replaces the line printed on your own agreement: check it before you sign, and check it again if you booked several months in advance.

The excess describes what you pay when the damage is covered. The real trap lies elsewhere: the list of damage no basic package covers at all, and for which you pay 100 % of the bill, excess or no excess. That list is remarkably consistent across continents, because it maps exactly onto the damage that happens most often and is hardest to pin on an identifiable third party.

An excess waiver bought at the counter does not erase that list: it lowers the excess on damage the waiver already covers. If the agreement excludes windscreens, a zero-excess package changes nothing for a cracked windscreen, because the damage sits outside the waiver in the first place — hence the separate “tyres and glass” add-on sold by most rental companies. So the useful question at the counter is not “what is the excess?” but “what stays excluded, even at zero excess?”, and you want that answer in writing.

There are only four possible strategies, and they are not always mutually exclusive — you might accept the excess on a three-day hire and hold an annual policy for everything else. What really separates them is not the headline price: it is who fronts the money if something happens, and how long that money stays tied up.

On price, the waiver sold at the counter is charged per day and remains the most expensive option on a daily basis; third-party policies bought online, especially annual multi-hire cover, typically cost a fraction of that for anyone who hires more than once a year. Exact amounts depend on country, category and season: compare written quotes, not memories.

The counter waiver has one genuine virtue: if you scrape the car, you hand over the keys and walk away. No money fronted, no claim file, no waiting. Its weaknesses are the daily price and, above all, the moment at which it is sold to you — after a night flight, in a queue, with an agent describing a worst-case scenario while your family waits outside. A study by Tao Chen, Ajay Kalra and Baohong Sun, published in 2009 in the Journal of Consumer Research, shows that buying these protection contracts sold as an add-on at the point of payment depends far less on the actual risk involved than on the purchase context and the nature of the product (study available on Google Scholar: scholar.google.com/scholar?q=Chen+Kalra+Sun+Why+Do+Consumers+Buy+Extended+Service+Contracts). The practical lesson: decide before you reach the counter, not standing at it.

Premium credit card cover, by contrast, is already paid for through your annual card fee. Its marginal cost is zero, which makes it the most rational option — when it applies. The conditions are strict and rarely read: the hire must be paid for with that specific card, there is a maximum continuous hire length (often only a few weeks), whole categories are excluded (vans, campervans, some 4x4s and luxury vehicles), payouts are capped, and you may be required to have declined the rental company's own waiver. And like third-party policies, it reimburses after the fact: the deposit is still held.

This is the point price comparison sites gloss over most often. Excess insurance bought online has no contractual link with the rental company: it therefore does not stop them holding the deposit at pick-up, nor charging the excess to your card if the car is damaged. The mechanism is reimbursement. You pay the rental company first, then you gather the hire agreement, the damage report, the itemised repair invoice and proof of the charge, and submit the file to your insurer, who refunds the account you paid from.

The practical consequences are concrete. You need enough card limit to absorb the deposit and the excess at the same time — call your bank before departure to have the limit raised if necessary. You also need to accept a cash-flow gap measured in weeks. And most policies impose a short notification deadline after the incident or the end of the hire: note it when you buy the cover, not when you claim.

In exchange, these policies usually cover exactly what the rental company excludes: tyres, glass, underbody, roof, keys, towing. For anyone hiring several times a year or going away for three weeks, an annual multi-hire policy remains, for comparable cover, the cheapest option on the market.

Walk round the car filming a timestamped video, slowly, narrating what you are recording: all four tyres and their wheels, windscreen and windows, the underbody filmed from a crouch, the roof and roof rack, the mirrors, each bumper, then the interior, the odometer and the fuel gauge. Add close-up stills of every existing mark. Have each defect written onto the condition report and keep a signed copy: it is the one document the rental company cannot argue with when you return the car.

On the agreement itself, find three lines before signing: the excess amount and its currency, the amount and nature of the deposit (pre-authorisation or actual debit), and the list of options you have genuinely bought. Check the name of every declared driver too, and the geographical restrictions: border crossings, whether unsealed roads are permitted, prohibited areas. Photograph the whole agreement.

At drop-off, insist on a signed return condition report. If the branch is closed or the return is automated, film the car again, the parking bay and the keys being deposited, and keep everything until the deposit has actually been released.

First question: how much money could you lose without the trip being ruined? If the excess is above that threshold, cover it, full stop. Second question: how many days, and how many hires in the year? Beyond one or two cumulative weeks, an annual third-party policy is almost always cheaper than a waiver charged per day. Third question: what terrain? On sealed roads in Europe, the dominant risk is a car park scrape; on Namibian, Icelandic or Patagonian gravel it is tyres, windscreen and underbody — precisely the items the counter waiver so often excludes.

A study by Levon Barseghyan, Francesca Molinari, Ted O'Donoghue and Joshua C. Teitelbaum, published in 2013 in the American Economic Review, shows that insurance deductible choices are explained above all by a marked overweighting of small probabilities: policyholders accept paying substantially more than the expected cost of the risk in order to lower their deductible (study available on Google Scholar: scholar.google.com/scholar?q=Barseghyan+Molinari+O%27Donoghue+Teitelbaum+Nature+of+Risk+Preferences+Evidence+from+Insurance+Choices). Translated to the rental counter: the natural instinct is to overpay to make a small risk disappear. That is not always a mistake — but it deserves to be a decision rather than a reflex.

In practice, one rule holds up in most cases: on a short hire, on sealed roads, with an excess you can absorb, keep your money and set it aside. As soon as the hire gets longer, the vehicle gets more valuable, or the route leaves the tarmac, buy cover — and buy cover that explicitly includes tyres, glass and underbody.
