When renting a car, few things cause more confusion (and stress) than insurance and excess. They are mentioned everywhere in your booking confirmation, rental agreement, and at the counter, but rarely explained clearly.

This guide explains car rental insurance vs excess in simple terms and helps you understand what you are paying for, what risks you are taking, and how to avoid unpleasant surprises when you return the car.

What is car rental insurance?

Car rental insurance determines what types of damage or loss the rental company will charge you for, and under what conditions. Most rentals automatically include basic insurance such as:

  • Collision Damage Waiver (CDW) - covers damage to the rental car.
  • Theft Protection (TP) - covers theft of the vehicle.
  • Third-Party Liability - covers damage or injury to others (often required by law).

Important: In car rental, insurance usually does not mean everything is free if something happens. That is where excess comes in.

What is excess in car rental?

Excess is the maximum amount you can be charged if the car is damaged or stolen.

Example

  • Damage repair cost: EUR 3,000
  • Excess stated in your rental agreement: EUR 1,200
  • You pay: up to EUR 1,200
  • The rental company covers the rest.

If the damage costs less than the excess, you pay the full amount.

In practice, excess is the renter’s financial risk.

Why car rentals have excess

Car rental companies use excess to:

  1. Limit their risk.
  2. Keep base rental prices low.
  3. Encourage careful driving.

Without excess, daily rental prices would be much higher.

Reducing or eliminating excess

This is where most renters get confused, and where many upsells happen.

Rental company excess reduction

At the counter, you may be offered:

  • Full coverage
  • Zero excess
  • Super CDW

This reduces or removes your excess, but is often expensive when bought directly from the rental company.

Third-party excess insurance

Some renters buy separate excess insurance from:

  • Their booking platform
  • A standalone insurer
  • A credit card provider

This usually works as reimbursement:

  • You pay the rental company first.
  • The insurer refunds you later, if covered.

Understanding which option you have is crucial.

Common excess pitfalls in car rental

Many renters only discover these after something goes wrong:

  • Excess applies per incident, not per rental.
  • Certain parts may be excluded (windows, tyres, roof, underbody).
  • Multiple excesses can apply (for example, standard plus young driver).
  • Damage admin fees may be charged on top.
  • Deposit blocked on your credit card often equals the excess.

Your rental confirmation usually contains this information, but it is rarely easy to read.

Should you reduce the excess?

It depends on:

  • Your budget.
  • Your driving confidence.
  • The excess amount.
  • Your existing coverage (credit card or travel insurance).

Rule of thumb: If you could not comfortably afford the excess tomorrow, consider reducing it.

Why understanding insurance vs excess matters

Many disputes at car return happen because renters:

  • Did not know how high the excess was.
  • Thought they had full insurance.
  • Did not realize certain damage was not covered.

Knowing the difference helps you:

  • Choose the right protection.
  • Avoid unnecessary upsells.
  • Feel confident if damage is reported.
