Car Rental Deposit in Iceland: What to Know Before You Book

Car rental deposits are one of the most common surprises travelers face when renting a car in Iceland. You may find a good daily rental price, start the booking process and then discover that the rental company requires a large deposit or credit card hold at pickup.

This can be frustrating, especially if you are traveling on a budget, using one main card for your trip or trying to avoid unexpected blocked funds while abroad.

With Zero Car, there is no rental deposit. Full insurance with zero excess, unlimited mileage, 24/7 roadside assistance and keybox pickup at Keflavik Airport are also included in the rental price. That makes the total cost easier to understand before you arrive in Iceland.

Quick answer: do you need to pay a car rental deposit in Iceland?

Many car rental companies in Iceland require a deposit or card hold when you pick up the vehicle. The amount depends on the rental company, vehicle type, insurance level and excess amount.

Zero Car does not require a rental deposit. This is one of the main benefits of renting with Zero. Instead of blocking a large amount on your card, Zero includes full insurance with zero excess in the rental price.

This matters because a rental deposit is not the same as the rental price. It is usually a temporary hold, but it can still reduce your available card balance during the trip.

What is a car rental deposit?

A car rental deposit is an amount that a rental company may block on your credit card during the rental period. It is used as financial security in case of damage, fines, missing fuel, lost keys, unpaid fees or other charges covered by the rental terms.

In many cases, the deposit is not charged immediately. Instead, it is held or reserved on your card. However, while the hold is active, that amount may not be available for hotels, fuel, restaurants, tours or other travel costs.

The deposit is usually released after the car is returned, provided there are no extra charges. The release time can vary depending on the rental company, bank and card provider.

Why do rental companies require deposits?

Rental companies use deposits to reduce financial risk. If a vehicle is damaged, returned late, returned with missing fuel or connected to traffic fines, the deposit gives the rental company a way to recover costs.

Deposits are especially common when the rental includes a high excess. If the excess is high, the company may block a larger amount on your card because you could still be responsible for part of the damage cost.

This is why the deposit, excess and insurance setup should always be reviewed together. A low daily rental price may look attractive, but the total rental setup may still include a large card hold and high financial liability.

Deposit vs excess: what is the difference?

A rental deposit and rental excess are connected, but they are not the same thing.

Term	What it means	Why it matters
Deposit	A temporary card hold or security amount during the rental.	It can reduce your available card balance while you travel.
Excess	The amount you may need to pay for covered damage under the rental terms.	A high excess can leave you financially exposed if damage happens.
Zero excess	Your excess is reduced to zero for covered damage.	It removes the covered excess amount from the rental terms.
No deposit	No rental deposit is blocked on your card.	You keep more of your card balance available during the trip.

With Zero Car, full insurance with zero excess is included and no deposit is required. You can read more about this on the full insurance included page.

Why a rental deposit can be a problem when traveling in Iceland

A deposit may be temporary, but it can still affect your trip. Iceland is not always a cheap destination, and travelers often need available funds for accommodation, fuel, food, activities and unexpected changes in plans.

A large card hold can create problems if:

• You are using one main credit card for the trip.
• Your card limit is close to being used.
• You have hotels or tours still waiting to charge your card.
• You need flexibility for fuel, food or weather-related route changes.
• Your bank takes several days to release the hold after the rental.

This is why no deposit car rental can be valuable. It gives travelers more flexibility and fewer financial surprises during the trip.

Traveler perspective: why no deposit matters

To understand why no deposit matters in practice, here is a short traveler-style interview based on a common question visitors have before renting a car in Iceland.

What were you most worried about before renting a car in Iceland?

Traveler: I was mostly worried about the deposit and the insurance. The rental price looked fine at first, but I did not want a large amount blocked on my card when I still had hotels, fuel and tours to pay for.

Why did the deposit matter so much?

Traveler: Iceland is already a trip where you need some flexibility. Weather can change plans, and you might spend more on fuel or food than expected. Having a large card hold would have made the trip feel tighter.

What made no deposit helpful?

Traveler: It made the cost easier to understand. I knew what I was paying for the car, and I did not have to worry about a big temporary hold or whether my bank would release it quickly after the trip.

Was insurance part of the decision?

Traveler: Yes. No deposit was important, but zero excess and full insurance were just as important. It felt better knowing that the main protection was already included instead of having to decide on extra insurance at pickup.

This is exactly why Zero Car is built around no deposit, full insurance and zero excess. The goal is to remove the most common rental worries before the trip starts.

Does Zero Car require a deposit?

No. Zero Car does not require a rental deposit.

Every Zero Car rental includes:

• No deposit
• Full insurance with zero excess
• Unlimited mileage
• 24/7 roadside assistance
• Keybox pickup at Keflavik Airport

This setup is designed to make renting a car in Iceland simpler. You do not need to worry about a large deposit being blocked on your card, and you do not need to choose between several insurance packages at pickup.

Why no deposit works well with zero excess

No deposit and zero excess work together. If a rental has a high excess, the company may need a deposit to cover possible liability. If the rental includes zero excess for covered damage, the need for a large security hold is reduced.

With Zero Car, the rental is built around included protection. Full insurance with zero excess is included in the price, so travelers do not need to leave a large deposit at pickup.

This helps make the final rental cost easier to compare. Instead of looking only at the daily rate, you can look at what is included from the start.

Why the cheapest rental price is not always the cheapest rental

A low daily rental price can look appealing, but it does not always show the full cost of renting a car in Iceland. The final price may change when you add insurance, lower your excess, pay for roadside assistance or leave a deposit.

Before booking, check whether the price includes:

• Full insurance
• Zero excess
• No deposit
• Unlimited mileage
• Roadside assistance
• Simple airport pickup

If these are not included, the final rental may cost more than expected. A slightly higher upfront price can be better value if it includes the things you actually need for driving in Iceland.

Can you rent a car in Iceland without a credit card deposit?

Some rental companies require a credit card because they need to block a deposit. Others may have different rules depending on insurance level, vehicle type or payment method.

Zero Car does not require a rental deposit, which removes one of the main reasons travelers worry about credit card holds. You should still bring a valid payment card and make sure your booking details match the rental terms.

If you are unsure about payment requirements, check the Zero Car FAQ before your trip.

What can still create extra charges?

No deposit does not mean there are no rental terms. Travelers are still responsible for using the vehicle correctly and following Icelandic road rules.

Extra charges may apply for things such as:

• Traffic fines
• Parking fines
• Speeding tickets
• Wrong fuel
• Lost keys
• Late return
• Misuse of the vehicle
• Driving on closed roads
• Off-road driving

Off-road driving is illegal in Iceland and can damage fragile nature. Always stay on marked roads, follow road signs and check road conditions before driving.

No deposit car rental at Keflavik Airport

Most international travelers arrive at Keflavik Airport before starting their Iceland road trip. After a long flight, the last thing you want is a slow pickup process, confusing insurance decisions or a large card hold at the counter.

Zero Car offers keybox pickup at Keflavik Airport. This means you can complete the process before arrival, collect your key and start your trip without waiting at the desk.

For pickup details, see the pickup and drop-off process.

How to compare no deposit rental offers in Iceland

When comparing rental companies, do not only look for “no deposit.” Look at the full rental package. A no-deposit offer is strongest when it is combined with clear insurance, zero excess and simple terms.

| Question to ask | Why it matters | | --- | --- | | Is there a deposit? | A deposit can reduce your available card balance. | | What is the excess? | A high excess can leave you responsible for a large amount. | | Is full insurance included? | Insurance add-ons can change the final price. | | Is roadside assistance included? | Roadside issues can be stressful in a remote destination. | | Is mileage unlimited? | Long routes can become expensive if mileage is limited. | | Is pickup simple? | Airport keybox pickup can save time after arrival. |

Zero Car checks these boxes by including no deposit, zero excess, full insurance, unlimited mileage, roadside assistance and keybox pickup.

Which car should you choose?

The right rental car depends on your route, season, luggage and group size. No deposit makes the booking easier, but you should still choose a vehicle that fits your Iceland itinerary.

A small car can work well for Reykjavík, the Golden Circle and paved South Coast routes in mild weather. A medium car or SUV gives more comfort for longer drives. A 4x4 is required for F-roads and recommended for many winter or remote routes.

Browse Zero Car’s small rental cars, medium rental cars, large cars and 4x4 options or electric rental cars.

Final advice: compare the full rental setup

A car rental deposit is easy to overlook, but it can affect your travel budget and card availability during your Iceland trip. Before booking, check the deposit, excess, insurance, roadside assistance, mileage and pickup process.

Zero Car keeps this simple. There is no deposit, full insurance with zero excess is included, mileage is unlimited, roadside assistance is included and pickup is handled through a keybox at Keflavik Airport.

That means fewer surprises, clearer cost planning and a smoother start to your Iceland road trip.
