Rental Car Deposits with a Credit Card: What You Need to Know

Why the car rental company requires a credit card

When you rent a vehicle, most car rental companies require a deposit as security – in case of damage, missing fuel or contractual penalties. Instead of actually charging the amount, they reserve it on your credit card. For this they need a card that reliably allows such a reservation.

This is exactly why many rental companies insist on a traditional credit card: it lets them place a binding hold on an amount without a balance having to be present – unlike most debit or prepaid cards.

How the pre-authorization works

When you pick up the vehicle, the rental company places a hold for a set deposit amount on your card. This amount is not charged, only reserved – but it reduces your available limit for the duration of the hold.

After you return the vehicle, the reservation is released, provided there is no damage or additional cost. Depending on the rental company and bank, the release can take from a few days to several weeks – plan for this if you need your available limit for something else in that period.

Debit card or credit card?

The type of card often decides whether the rental works at all:

• Traditional credit card: accepted by almost all rental companies and the standard for the deposit.
• Debit card: accepted only by some rental companies and often with restrictions, such as additional proof or a higher deposit.
• Prepaid card: generally not accepted for the deposit, because no binding pre-authorization is possible.

What to watch for

Before renting, it is worth checking these points:

• Sufficient available limit: the deposit can be several hundred to over a thousand euros and must be freely available.
• The card usually has to be in the name of the main driver.
• Renting abroad can incur foreign transaction fees – both on the deposit and on the final bill.
• Watch the exchange rate at the hold and at the release: with currency fluctuations a small difference can arise.

Tips for a smooth rental

Before your trip, check your available limit and whether it covers the expected deposit – with a traditional credit card you can, if necessary, ease the limit with a balance paid in advance. Abroad, pay in the local currency wherever possible to avoid unfavourable conversions (Dynamic Currency Conversion).

Keep the receipt for the pre-authorization until the deposit has been fully released. That way you can prove, if in doubt, which amount was reserved and when.
