For drivers under 25, SIXT and Enterprise Holdings brands (Enterprise, Alamo, National) are top choices due to widespread low-age policies and clear fee structures. While SIXT often rents to 18-year-olds at many locations, Enterprise group companies typically allow rentals starting at age 20. The "best" place depends on your exact age, location, and budget, as daily "young renter" fees range from $15 to $35+, significantly impacting total cost.
The primary challenge for under-25 renters is not availability but cost and restrictions. Major rental companies almost universally apply a "Young Renter Fee" or "Underage Surcharge" to drivers under 25. This daily fee is the most critical factor to compare.
SIXT stands out for its relatively low minimum age. At many U.S. and European locations, the minimum age to rent is 18, though for certain vehicle categories (like premium cars), it may be higher. Their young driver surcharge is transparently listed during the booking process. Enterprise, Alamo, and National typically set a minimum age of 20 in the U.S. and Canada (21 in other countries), but they have a vast network and consistent policies. Their young renter fee is usually on the lower end of the industry scale.
Hertz and Avis/Budget generally require renters to be at least 20 years old, with higher underage fees. Their policies can be more variable by location. A key strategy is to book through the corporate website or app, as third-party platforms sometimes misrepresent age policies and fees.
| Company / Brand | Typical Minimum Age (US) | Under-25 Fee (Daily, Approx. USD) | Key Consideration |
|---|---|---|---|
| SIXT | 18 at many locations | $20 - $30 | Best for ages 18-20. Fee and vehicle options vary by rental country. |
| Enterprise, Alamo, National | 20 | $15 - $25 | Consistent policies, large fleet. Often the most cost-effective for 20-24 year olds. |
| Hertz | 20 | $19 - $35+ | Fee varies by state/country and rental car class. Can be among the highest. |
| Avis / Budget | 20 (21 in NY) | $27 - $35+ | Similar to Hertz, with fees prominently displayed during booking. |
Beyond fees, vehicle choice is limited. You'll often be restricted to economy, compact, or intermediate car classes. Luxury, premium, SUVs, and minivans are usually unavailable to drivers under 25.
To secure the best deal, follow these steps: First, use the rental company's official website to get a quote, ensuring you input your correct age and location. The final price will include all mandatory fees. Second, consider membership discounts (like AAA, USAA, or costco) which can sometimes waive or reduce the young renter fee. Third, always have a major card in your name for the security deposit. Finally, understand that additional drivers under 25 will incur their own surcharges.
Market data from corporate policy pages and traveler reports in 2023-2024 consistently shows that proactive comparison shopping can reduce the total cost of an under-25 rental by 20-30%. The process is manageable with precise planning and direct booking.

As a 22-year-old who rents for weekend trips, I always check Enterprise first. Their under-25 fee is usually around $20 a day, which is lower than what I’ve seen elsewhere. I just booked a compact car for a three-day trip, and the total with the young driver fee was still reasonable compared to quotes from Hertz or Avis for the same dates. My tip is to book directly on their site—it’s straightforward, and the final price includes all the extra charges so there are no surprises at the counter. For me, that transparency makes it the best practical option.

Let’s talk budget. If you’re under 25, the biggest line item isn’t the rental rate—it’s the daily young driver surcharge. From my research, these fees aren’t flat; they change based on the company, the city, and even the type of car. SIXT might let you rent at 18, which is great, but their fee can be high. Enterprise and Alamo often have more moderate surcharges. The real cost-saver isn’t finding a company with no fee (that’s nearly impossible), but finding one with a predictable, lower fee and pairing it with a membership discount. Always run the final quote on two or three sites before deciding. The difference can be over a hundred dollars for a week-long rental.

Parents helping a college-age kid rent a car should look at Enterprise Holdings. Why? Reliability and clear rules. Companies like Enterprise and National have a minimum age of 20 and their policies are consistent nationwide. When my son needed a car for an internship, we chose Alamo because their young renter fee was clearly stated upfront ($22/day), and the process was simple. We avoided companies with more complex fee structures or higher minimum ages for certain car types. For peace of mind, especially if your child is new to renting, a company with a straightforward and widespread locations is often the best choice, even if the base rate is a few dollars more.

The search for the best rental car deal under 25 boils down to a simple equation: Base Rate + Young Renter Fee + Taxes. Ignore the advertised base rate; focus on the final total. My experience across five rentals last year showed that SIXT had competitive base rates but their young driver fee pushed the total up. Enterprise frequently had a slightly higher base rate but a lower daily surcharge, making the total cost better for rentals longer than two days. Your specific airport or city matters too—some franchise locations have slight fee variations. Always pay with a card that provides primary rental insurance; this saves you from buying the expensive coverage from the rental company, which is a huge cost saver for any young driver.
