In most states, you must be at least 21 years old to rent a car. However, if you are between 21 and 24 years old, you will almost always be charged a Young Renter Fee or Underage Surcharge, which can add $25 to $50 per day to your rental cost. The standard age to rent a car without these extra fees is typically 25.
The rules can vary significantly by rental company, location (including specific airport policies), and even the type of vehicle you want to rent. For example, renting a luxury car, SUV, or minivan might require you to be 25 or older, regardless of the state's minimum age. Major rental companies like Hertz, Enterprise, and Avis generally adhere to the 21-and-over , but it's crucial to check directly with the company and the specific branch where you plan to rent.
To streamline the process, always have your valid driver's license, a major credit card in your name (debit cards often come with additional requirements or holds), and proof of any available insurance. Calling the rental location ahead of your trip is the most reliable way to confirm their age policy and avoid surprises.
| Rental Company | Standard Minimum Age | Age for Young Renter Fee (21-24) | Estimated Daily Surcharge | Notes |
|---|---|---|---|---|
| Enterprise | 21 | 21-24 | $20 - $30 | May vary by state; some airport locations may have a minimum age of 21. |
| Hertz | 20 (in some states like MI and NY) | 21-24 | $25 - $35 | Minimum age is typically 21; younger ages permitted in specific states. |
| Avis | 21 (18 in NY and MI) | 21-24 | $27 - $35 | Surcharge and vehicle class restrictions apply to under-25 renters. |
| Budget | 21 | 21-24 | $25 - $35 | Similar policies to Avis; luxury vehicles often restricted to 25+. |
| Sixt | 18 (at most locations) | 18-24 | €30 (approx. $33) | One of the more flexible companies, but surcharges still apply to young renters. |

Just went through this trying to rent a car for a trip. I'm 22, and yeah, you can do it, but they hit you with a "young driver" fee that was like thirty bucks a day. It basically doubled the cost of the cheapest car. My advice? If you're under 25, be ready for that extra charge. Always call the actual rental place you're going to—their website doesn't always tell you the whole story.

From a corporate perspective, the minimum age is often 21 for standard rentals. The primary concern is risk management, as drivers under 25 statistically represent a higher insurance liability. Therefore, the underage surcharge functions as an additional premium to offset this risk. For business travel, many companies have negotiated contracts that waive this fee for employees aged 21-24, so it's worth checking with your employer's travel department before paying out-of-pocket.

We rented a minivan for a family vacation last summer, and our son is 23. He was allowed to be an additional driver, but we still had to pay the young renter fee for him even though he wasn't the primary renter. It added up over a week. If you're traveling with younger drivers, factor that into your budget. Some cards offer auto rental coverage that might help, but they usually don't cover these age-based fees.

Having rented cars for decades, I've seen the policies tighten up. While you can find a few places that will rent to 18-year-olds, it's rare and comes with heavy restrictions. The sweet spot is 25, when those pesky fees disappear. For anyone under that age, my number one tip is to use a major card for the rental. They often provide primary insurance coverage, which is crucial because the rental company's own insurance for young drivers is prohibitively expensive. Shop around online and read the fine print on age requirements.
