What you're paying for when you rent a car

A car rental is a short-term lease of a vehicle, usually for days or weeks rather than months or years. You pay a daily rate, return the car on an agreed date, and walk away. The rental company owns the car, maintains it, and insures it against major damage — but you're responsible for the condition you return it in and for traffic violations or accidents that happen while you're driving.

The daily rate is only part of what you'll pay. Rental companies add taxes (which vary by state and city), facility fees, and optional insurance. Some charge extra for drivers under 25, for additional drivers, or for returning the car to a different location than you picked it up. A $40-per-day rate can easily become $60 or $70 once everything is added in.

The rental agreement is a contract that spells out what damage you're liable for, what happens if you return the car late, and what the company can charge your credit card if something goes wrong. Read it before you sign, because the terms vary between companies and between locations of the same company.

Key Takeaways

  • Daily rental rates don't include taxes, facility fees, or insurance, so your final bill will be higher than the advertised price.
  • You are responsible for returning the car in the same condition you received it, minus normal wear, and you pay for any damage beyond that.
  • The rental company's insurance (called a Loss Damage Waiver) is optional but expensive; check whether your personal auto insurance or credit card covers rental cars before you buy it.
  • Returning a car late triggers daily charges that can be higher than the original rental rate, so confirm your return time in writing.
  • Most rental companies require a credit card at pickup, even if you've already paid online, to hold a security deposit.

How the rental process works from start to finish

You reserve a car online or by phone, providing your driver's license number, the dates you need it, and where you want to pick it up and drop it off. The company gives you a quote that includes the daily rate, taxes, and any fees for extra drivers or one-way rental. That quote is usually good for 24 hours.

At pickup, you'll show your driver's license and the credit card you used to reserve the car. The agent will walk you around the vehicle, noting any existing damage on the rental agreement — dents, scratches, stains. This is called the vehicle inspection, and it protects you by documenting what was already wrong. Take photos of the car yourself if you can, especially of any damage the agent points out. You'll also sign the rental agreement, which includes the terms for late returns, damage liability, and what happens if you get a ticket or are in an accident.

When you return the car, the agent inspects it again and compares it to the condition at pickup. If there's new damage, the company will charge you for repairs. If you return it late, you'll be charged for the extra days. The company will run your credit card for the final amount, which may be higher or lower than your original quote depending on what you actually used and what damage was found.

Understanding damage liability and insurance options

You are liable for damage to the rental car unless the rental company's insurance covers it. The company offers a Loss Damage Waiver (sometimes called a Collision Damage Waiver or CDW), which is optional insurance that limits your liability to a small deductible — usually $0 to $1,500 — if the car is damaged or stolen. This costs $15 to $30 per day depending on the car and location.

Before you buy the Loss Damage Waiver, check two things. First, does your personal auto insurance cover rental cars? Many policies do, which means you're already protected and paying for the Loss Damage Waiver is redundant. Second, does your credit card cover rental damage? Many premium credit cards include rental car insurance if you charge the entire rental to that card. Call your insurance company and credit card issuer before you rent to find out what they cover.

If neither your insurance nor your credit card covers rental damage, the Loss Damage Waiver is worth buying. Without it, you could be charged thousands of dollars for repairs to a car you don't own. With it, your out-of-pocket cost for damage is capped at the deductible.

What happens if you return the car late

Your rental agreement specifies a return time — usually the same time of day you picked up the car. If you return it after that time, you'll be charged for the extra hours or days. The late fee is often higher than your daily rate. For example, if you rented a car for $50 per day but return it 3 hours late, you might be charged $75 for those 3 hours instead of a prorated $6.25.

Some rental companies have a grace period of 29 minutes or an hour before they charge you for a late return, but this varies. Don't rely on it. If you think you might be late, call the rental location and ask to extend your reservation. If you extend before the return time, you'll pay the daily rate for the extra day. If you extend after you're already late, you'll pay the late fee.

Plan to return the car with enough time to account for traffic and to refuel it if the rental agreement requires you to return it full. Most companies charge a refueling fee if you return the car with less than a full tank, and that fee is usually much higher than what you'd pay at a gas station.

Comparing rental companies and finding the best rate

The major national rental companies — Enterprise, Hertz, Budget, Avis, and National — have different pricing and policies. Enterprise and Budget tend to have lower daily rates but may charge more for additional drivers or one-way rentals. Avis and National often have higher daily rates but include some extras like unlimited mileage or a second driver at no charge. Hertz's pricing varies by location.

Comparison websites like Kayak, Autoslash, and Priceline let you search multiple companies at once and see the total cost including taxes and fees. Enter your pickup and return dates, location, and driver age, then sort by total price. The cheapest option isn't always the best — a company with a lower daily rate might charge more in facility fees or have stricter damage policies.

Book directly with the rental company's website if you find a better rate there than on a comparison site. Some companies offer loyalty discounts or prepay discounts that don't show up on third-party sites. Read the cancellation policy before you book — most allow free cancellation up to 24 hours before pickup, but some don't.

Special situations: One-way rentals, drivers under 25, and additional drivers

A one-way rental means you pick up the car in one city and return it in another. This costs more than a round-trip rental because the company has to move the car back or reposition it for another customer. The extra charge can be $50 to $300 or more depending on the distance. Some companies waive the one-way fee during slow seasons or if you book far in advance.

Drivers under 25 are charged a daily surcharge, usually $15 to $25, because they're statistically more likely to be in an accident. Some companies won't rent to drivers under 21 at all. If you're under 25, call ahead to confirm the surcharge and whether you're old enough to rent.

Additional drivers — anyone else who will drive the car — must be listed on the rental agreement. Most companies allow one additional driver at no charge, but charge $10 to $15 per day for a second additional driver. All drivers must have a valid driver's license and meet the company's age requirements. If someone drives the car who isn't listed on the agreement and gets in an accident, the insurance may not cover it.

What to do if you get a ticket or are in an accident

If you get a traffic ticket while driving a rental car, the ticket is your responsibility. The rental company will receive a notice from the court, then charge your credit card for the ticket amount plus an administrative fee (usually $15 to $25). Pay the ticket yourself if you can to avoid the fee, or dispute it if you believe it's wrong.

If you're in an accident, tell the rental company when ready. Don't admit fault or sign anything except a police report. Get the other driver's name, phone number, address, driver's license number, and insurance information. Take photos of the damage to both cars and the accident scene. The rental company will file a claim with its insurance or with the other driver's insurance, depending on who was at fault.

If you have the Loss Damage Waiver, your liability for damage to the rental car is limited to the deductible. If you don't have it and you're found to be at fault, you'll be charged for all repairs. This is why checking your personal insurance and credit card coverage before you rent is important.

Frequently Asked Questions

Do I need to buy the Loss Damage Waiver if my credit card covers rental cars?

No. If your credit card covers rental damage and you charge the entire rental to that card, you don't need to buy the Loss Damage Waiver. Call your credit card issuer to confirm what's covered — some cards cover collision but not theft, and some have limits on the amount they'll pay.

What happens if I return the car with an empty gas tank?

The rental company will charge you a refueling fee, which is usually $8 to $15 per gallon — much higher than the market price of gas. Most rental agreements require you to return the car with a full tank. If you can't fill it yourself, fill it as much as you can and the company will charge you for the rest.

Can I rent a car if I don't have a credit card?

Most rental companies require a credit card to hold a security deposit, even if you've already paid for the rental with cash or debit. Some companies will accept a debit card, but you'll need to call ahead and confirm. A few companies in major cities accept cash, but this is rare.

What if the rental car breaks down while I'm driving it?

Call the rental company's roadside information number when ready. The number is on your rental agreement and on the key tag. The company will arrange a tow or send a replacement car. You're not responsible for mechanical failures — that's the company's responsibility as the car's owner.

Can I smoke in a rental car?

Most rental companies prohibit smoking and charge a cleaning fee of $150 to $300 if they find smoke damage or smell. Some companies have designated smoking cars, but you have to request one at pickup. If you smoke, ask for a smoking car or plan to smoke only outside the vehicle.
