Kayak Car Rental Age: What You Need to Know

Last Updated on June 29, 2026 by Jaxon Mike

When you’re looking to rent a car through Kayak, the minimum age to rent is typically 21. However, this can vary quite a bit depending on the specific rental company you book with. Many major companies impose a surcharge for drivers under 25.

This age requirement isn’t just a Kayak rule; it’s set by the car rental agencies themselves. We found that booking with companies like Hertz, Avis, or Enterprise usually follows this general guideline. Always double-check the terms for your chosen rental car to avoid surprises.

• Minimum age is usually 21.
• Drivers under 25 often pay an extra fee.
• Age rules are set by the rental company, not Kayak.
• Check the specific rental car’s terms.

Ready to find out more about the age rules and what other factors might affect your rental? Let’s walk through exactly what you need to know about renting a car with Kayak as a younger driver.

Renting a Car on Kayak: Understanding Age Requirements

So, you’re planning a trip and need a set of wheels. Kayak is a fantastic tool to compare prices from many rental companies. But before you click ‘book,’ let’s talk about age. It’s a common question, especially for younger travelers. Can you rent a car if you’re under 25? The short answer is usually yes, but there are definitely a few things you need to know.

Kayak itself doesn’t set the age rules. Instead, it acts as a marketplace. We found that the minimum age to rent a car is determined by each individual rental company listed on Kayak. This means the age policy can differ between Hertz, Avis, Budget, and so on. It’s like shopping for shoes; everyone has their own sizing chart.

The Magic Number: What’s the Minimum Age?

We’ve researched this extensively for you. The general consensus for most major rental companies is that you must be at least 21 years old to rent a car. This applies to a vast majority of bookings you’ll find through Kayak. Think of 21 as the entry point for renting a vehicle in most cases.

However, it’s not quite that simple for everyone. While 21 is the minimum, many companies prefer renters to be older. This preference often comes with extra costs for drivers who fall into the younger age bracket.

What About Drivers Under 25?

This is where things get a little more specific. If you’re between 21 and 24 years old, you can likely still rent a car. But, be prepared for what the industry calls a “young renter fee” or “underage fee.” We found that this surcharge is very common and can significantly increase the daily rental cost. It’s not a fixed amount either; it varies by company and location.

Why do they charge extra? Rental companies view younger drivers as a higher risk. Their insurance policies often reflect this. The fee helps to offset the potential costs associated with this perceived higher risk. It’s similar to how insurance rates can differ based on age for other things.

Are There Any Exceptions?

Sometimes, yes! While 21 is the standard minimum, we’ve seen some companies with slightly different policies. For example, a few might allow renters who are 18. These situations are less common and often come with stricter vehicle restrictions. You might find these at smaller, local agencies or at airports catering to specific needs. Always, always check the terms and conditions for your specific booking.

We recommend doing a quick search on Kayak and then clicking through to the rental company’s details page. This is where you’ll find the exact age requirements and any associated fees. Don’t just assume; verify!

Navigating Age Restrictions with Specific Companies

Since Kayak aggregates offers from various providers, understanding individual company policies is key. We’ve compiled some general findings on popular rental agencies you might encounter:

Hertz, Avis, Enterprise, and Similar Major Brands

These giants typically follow the 21-year-old minimum rule. For drivers aged 21-24, expect the young renter fee. We found these fees can range from $20 to $50 per day, sometimes more. Enterprise, for instance, often has a daily fee for drivers under 25 at most of its corporate-owned locations.

Budget and Other Value Brands

Companies like Budget might also require renters to be 21. Their young renter fees can be comparable to the major brands. It’s worth noting that some smaller franchise locations might have slightly different rules, so checking each specific listing is vital.

Special Circumstances: Business Travelers and Younger Drivers

Are you renting for business? Some corporate accounts or specific programs might waive the young renter fee. This isn’t automatic, though. You’d typically need to be part of a specific program or have your employer arrange the rental under their negotiated terms. We found this is more common for company employees on official travel.

For college students, some companies offer discounts or have specific programs that might make renting easier. Always look for these deals when you search on Kayak. You might find a gem that simplifies things.

Factors Beyond Just Age

While age is a big piece of the puzzle, other requirements will also apply. You’ll always need a valid driver’s license. We found that most companies require it to be held for at least one year. An international driving permit might be necessary for foreign licenses.

Credit Card and Payment Requirements

This is a big one. To rent a car, you generally need a major credit card in your name. Debit cards are sometimes accepted, but policies vary wildly. We found that using a debit card often comes with stricter requirements, like a credit check or a larger security deposit. This is true regardless of your age, but it’s especially important for younger renters who might not have extensive credit histories.

The credit card is used to place a hold for the estimated cost of the rental, plus a security deposit. This deposit is refunded after you return the car in good condition. Without a qualifying credit card, renting can become quite challenging.

Insurance Considerations

Car rental insurance can be confusing. Do you need it? What does it cover? Your personal auto insurance might extend to rental cars, but it’s essential to check your policy. Many credit cards also offer secondary or even primary rental car insurance. We found that understanding your existing coverage can save you a lot of money and hassle.

If you don’t have adequate coverage, you’ll likely be offered Collision Damage Waiver (CDW) or Loss Damage Waiver (LDW) by the rental company. You can also purchase supplemental liability insurance. For drivers under 25, the young renter fee often doesn’t include enhanced insurance; you’re usually paying for the privilege of renting, not necessarily for better coverage.

Making Your Kayak Rental Smooth

So, how do you ensure a hassle-free rental experience with Kayak, especially if you’re a younger driver? It boils down to preparation and careful review.

The Checklist for Younger Renters

• Confirm you are at least 21 years old.
• Check the specific rental company’s age policy.
• Look for any “young renter fees” or underage surcharges.
• Ensure you have a valid driver’s license held for at least a year.
• Have a major credit card in your name for the deposit.
• Review your personal insurance and credit card benefits for coverage.

By taking these steps, you can avoid unexpected charges and ensure you’re legally able to drive your rental car. Kayak is a great starting point, but the final details always lie with the rental company providing the car. Happy travels!

Frequently Asked Questions

What if I’m 18, 19, or 20 years old? Can I rent a car through Kayak?

Generally, you cannot rent a car from most major companies listed on Kayak if you are under 21. While some rare exceptions might exist with smaller agencies allowing renters as young as 18, these often come with strict vehicle limitations and higher fees. We found that 21 is the most common minimum age requirement.

How much is the “young renter fee” typically?

The young renter fee, applied to drivers aged 21-24, varies significantly by rental company and location. We’ve found these fees can range anywhere from $20 to $50 per day, and sometimes even more. It’s essential to look for this specific charge on the rental company’s details page on Kayak.

Will Kayak show me the young renter fee upfront?

Kayak’s search results often display the base rate. However, the exact young renter fee is typically detailed on the individual rental company’s terms and conditions page, which you access by clicking through from Kayak. We advise carefully reviewing these details before confirming your booking.

Can I avoid the young renter fee by using a debit card instead of a credit card?

Using a debit card usually doesn’t exempt you from the young renter fee. In fact, debit card rentals often have stricter requirements and may require a larger security deposit regardless of your age. The fee is primarily based on your age and the perceived risk associated with younger drivers.

Are there any companies on Kayak that allow drivers under 21 to rent?

It’s uncommon, but some smaller or specialty rental agencies might allow drivers as young as 18. However, these rentals often have very specific vehicle restrictions and may come with additional insurance requirements or higher daily rates. Always verify the precise age policy directly with the rental provider found via Kayak.
