Navigating the Open Road: Understanding Unlimited and Limited Mileage in Car Rentals

PUBLISHED ON Jan, 25 2024

UPDATED ON Jan, 29 2024


Renting a car for a road trip or business travel often comes with a critical decision: unlimited or limited mileage? This choice can significantly impact the cost of your rental and the flexibility of your travel plans. This article will dive into the details of both options, helping you make an informed decision for your next car rental.

What is Unlimited Mileage in Car Rentals?

Unlimited mileage is a car rental policy that allows you to drive as many miles as you want without incurring any additional fees. This policy contrasts with a set mileage allowance, where extra charges apply for miles driven over the allowance. Unlimited mileage is particularly beneficial if your travel distance is uncertain or if you desire the flexibility to alter your plans.

Companies like Avis, Budget, Enterprise, Hertz, and Thrifty offer car rentals with unlimited mileage. However, it’s important to read the terms and conditions of your rental agreement carefully to avoid any surprises at the end of your rental. Some car rental companies may have restrictions on unlimited mileage, such as a maximum number of days or miles per year.

Limited Mileage: What Does it Mean?

On the other hand, limited mileage or a mileage cap means your car rental has a set number of miles you can drive per day or per rental period. If you exceed this limit, you’ll be charged for every extra mile or kilometer at a fixed rate, typically around $0.10 – $0.25. This option is suitable for shorter trips where you’re more certain about the total distance.

Limits vary by rental company but can range from 20 miles per day to 250 miles per day. Therefore, it’s crucial to check the terms and conditions of your rental contract.

Unlimited vs. Limited Mileage: Which is Cheaper?

At first glance, limited mileage car rentals seem cheaper. However, the cost-effectiveness of unlimited or limited mileage largely depends on your travel plans. If you’re planning on driving a significant number of miles, unlimited mileage could be the more economical option. With unlimited mileage, you don’t have to worry about keeping track of your miles or being charged for overages, which can save you money if you end up driving more miles than you originally planned.

On the contrary, if your travel involves less driving, limited mileage may be a better option. It will be less expensive upfront, and you won’t have to worry about extra charges if you stay under your mileage allowance.

What Insurance is Best for You on a Car Rental with Unlimited Mileage?

All car rental companies offer basic insurance for all trips. The objective is to prevent a driver from traveling without insurance, something that is illegal, which is why companies include a basic policy that covers the basic assumptions. In the event of a situation that includes expenses greater than those insured, it will be the renter himself who must bear the costs incurred.

To avoid situations in which you must pay for the consequences derived from an accident, at CarInsuRent we offer you the possibility of taking out very affordable insurance, which covers vehicles in all types of situations, both on national and international routes.

Our insurance is specially designed for rental services, which is why it covers you in the following cases:

  • Damage due to collision or vehicle theft
  • Theft of personal items
  • Vehicle delivery charges
  • Fuel errors

In these cases, and many more, the Rental Car Excess Insurance policy takes care of the payment up to a limit, which will depend on the policy contracted.

When to Opt for Car Rental with Unlimited Miles?

Choosing a rental car with unlimited mileage is typically the safest option unless your travel route is set in stone. Here are several common scenarios where an unlimited mileage car rental might be the best choice:

  • You anticipate extensive daily driving during your trip
  • You’ve booked a long-term rental
  • Your journey involves crossing state borders
  • Your business travel includes multiple destinations
  • You value flexibility and peace of mind
  • You want to steer clear of expensive extra mileage fees
  • You prefer not to monitor the odometer constantly
  • Your travel plan covers a vast distance

If you’re in search of a rental car that accommodates pets, this requirement might outweigh considerations about mileage. Most car rental companies permit pets in their vehicles, with a few exceptions. However, it’s crucial to return the rental car in a clean state and be prepared to cover any additional cleaning costs or damage.

Tips for Finding a Cheap Rental Car with Unlimited Mileage

Finding a cheap rental car with unlimited mileage requires some strategy. Here are a few tips:

  • Use a price comparison website. Platforms like Rentalcars and KAYAK make it easy to compare prices from different car rental companies, ensuring you get the best deal on an unlimited mileage car rental.
  • Book your rental in advance. Car rental rates tend to be higher if you book your rental on the day of your trip. So, it’s a good idea to book your rental in advance.
  • Consider off-peak travel times. Car rental rates are usually lower during the off-season or during the weekdays. So, if possible, try to travel during these times.
  • Be flexible with your dates and rental location. If you are flexible with your travel dates and rental location, you may be able to find a cheaper car rental.


Unlimited mileage rental cars offer cost-effectiveness, flexibility, and peace of mind, especially for those planning on driving a lot of miles. However, if your travel involves less driving, a limited mileage rental could be a more economical choice. Understanding these options and evaluating your travel plans can help you make the best decision for your car rental needs. Whether you choose unlimited or limited mileage, the most important thing is to enjoy your journey and the freedom that comes
