As much as we might love public transportation when we travel, there are times when renting a car just makes the most sense for a particular destination or trip. When you absolutely need to have your own vehicle to get around, here are some of the things you can do to help find the cheapest rental car nearly anywhere you want to go.

1. Start With an Aggregator Site...

Begin your search with the aggregator site of your choice (such as Kayak or Priceline). This gives you a chance to see several rental car company options at once, as well as allowing you to filter for companies that allow you to drop the car off in a different country from the one in which you rent it. Those of you who are under 25 can also filter for companies that allow car rentals for younger drivers, though keep in mind there is often an “underage driver fee” associated with these rentals.

2. ...Then Compare Rates on the Rental Company’s Site

After getting an overview of your options on an aggregator site, don’t book anything until you’ve compared those rates with the rates on that rental car company’s site. In some cases, there may be a special discount or deal available on the official site that’s not available anywhere else.

3. Check Rates on Costco

If you’re a Costco member, check rates on Costco Travel, which often has the cheapest rates. It’s an especially good value if you’re sharing driving duties, as Costco doesn’t charge to add a second driver.  

4. Consider Lesser-Known Options

While the big-name companies might get all the limelight, smaller car rental agencies abound—some are even local to the place you’re visiting, so you won’t have heard of them before. Try searching at CRX to see if there are any cheaper car rental companies serving your destination.

Also, depending on where you’re going, don’t overlook peer-to-peer and car-sharing options, too. With Turo, you can “rent” a car from a private owner—it’s a bit like Airbnb, only for cars instead of vacation rentals. And if you’re a ZipCar member, you can book cars in their fleet by the hour or the day.

5. Always Choose the Cheapest Economy Car

Assuming you don’t need something bigger for a large family group (or a 4WD for a winter trip), you’ll get the best price if you book the cheapest car option available. You’ll be prompted numerous times to upgrade for a fee—don’t do it. In some cases, there won’t be any economy or subcompact cars available when you arrive at the rental counter to pick up your car, so you’ll end up with an upgrade anyway—and you won’t have to pay for it. The worst case scenario is that you end up with an economy car, which really isn’t so bad (those cars cost less to refuel, after all).

6. Compare Rates: Weekly vs. Weekday vs. Weekend

There’s no rhyme or reason for the duration of time that’s cheapest for car rentals. Sometimes it’s cheapest to rent for only the days you need the car, sometimes it’s cheaper to rent for a week even if you only need a car for a few days. In other words, be sure to check both before you book—just make sure the rental car company won’t charge a fee if you return the car early.

Also keep in mind that because business travelers frequently rent cars, and business trips are predominantly over weekdays, weekend rentals are often less expensive than weekday rentals. If the timing of your trip is flexible, shifting your schedule so you’re renting a car over a weekend might save you some money.

7. Look at Renting Away From the Airport

Sure, there’s no getting around the convenience of picking up a rental car before you even leave the airport—but there’s a price to be paid for that convenience. With very few exceptions (think big cities that aren’t ideal for driving in anyway), renting a car at the airport is nearly always more expensive than renting a car from another location of the same company’s rental offices. Compare the rental rates and associated fees (and don’t forget to factor in the cost and time involved with getting to the off-airport rental office) to see which is cheaper.

8. Skip the Upgrades

In addition to the vehicle upgrades you’ll be tempted with during the booking process, there are a host of extras and add-ons you could choose—all of which will cost you money. Pay attention to what’s being offered and, when possible, just say no.

  • GPS: You’ve got GPS on your phone, so don’t pay the additional fee for a GPS unit for the car. Just remember to bring a charger to keep your phone juiced up as you go, and a mounting device to make it easier to read the map while you’re driving. And, if you’re traveling overseas and don’t want to rack up all the data charges, go analog and get a good paper map.
  • Toll Pass: Cars in areas with lots of highway tolls often have passes on the windshield that are automatically read at toll booths, saving drivers time. Rental cars have these passes, too, but the daily fees that come with them are usually more expensive than if you just paid the tolls with a credit card or in cash as you passed through. Not only that, sometimes rental car companies will charge a daily fee whether you use the pass or not.
  • Car Seat: No, we’re not suggesting you leave your kiddo unsafe in a rental car—we’re just suggesting that if you can bring your own car seat, you’ll save the daily fee the agency would charge you. 
  • Frequent Flyer Miles: In many cases, car rentals can earn frequent flyer miles for the airline of your choice. What you may not realize is that sometimes the rental car company will charge you a daily fee for the privilege.

9. Decline Insurance

Before you check the box accepting the car rental company’s insurance coverage, do your homework. Many credit cards automatically include the required insurance coverage for a car rental when you use that card, so check your credit cards to see what they offer. If you’re traveling in your own country, any car insurance you carry on your personal car may extend to rental cars, too, so double-check that.

10. Look for Membership Discounts and Coupons

Sometimes car rental discounts are in obvious places—if you’re a member of AAA, for instance, there are car rental deals available for members. You’d expect that, since AAA is all about cars.

Sometimes, though, car rental discounts are in places you might not think to look. Here are just a few, but this isn’t an exhaustive list. If you pay for membership to anything, ask whether they have a partnership with any car rental companies for exclusive deals.

  • The company or organization where you work
  • AAA
  • AARP
  • Military/Veteran
  • Groupon
  • Hotel loyalty program
  • Airline loyalty program
  • Credit card

11. Stick to One Driver

The cost of renting a car includes one driver (except, as noted above, when booking with Costco Travel). You can always add another driver (or more), but there’s usually a daily fee for each additional driver. As long as it makes sense and is safe to do so, leaving only one person in charge of all the driving saves money. (Deputize someone else to be in charge of navigation, finding parking, or counting out cash for tolls to divvy up transportation responsibilities.)

12. Get a Manual Transmission (If You Can Drive It)

In many parts of the world, automatic transmission rental cars are more rare—and more expensive. If you know how to drive a stickshift, you can save quite a bit, depending on the country. (But if you don’t know how to drive a stickshift, don’t try to learn on a rental car.)

13. Pay Up Front...

Some rental car companies offer a discount if you pay for the rental during the booking process rather than when you actually pick the car up. This isn’t always the case, but it’s worth checking, as the discount can be as much as a third off the total price.

14. ...Or Use Autoslash to Track Prices and Cancel and Rebook When Prices Drop

In other cases, reserving a car without paying means you can keep checking rental rates (or use Autoslash, which tracks prices and notifies you if the price decreases for your dates), and if you find a better deal, you can cancel the original rental and book the cheaper one. Pay attention to any deadlines for canceling the original booking, however, or you may be stuck paying a cancellation fee.

15. Pump Your Own Gas

Most of the time, you need to either return rental cars with a full tank of gas or you’re stuck paying the exorbitant rates the companies charge for fuel. Getting gas yourself before you return the car is one of the easiest ways to avoid an insanely-high extra fee, but gas stations near the airport often have higher prices. Try the GasBuddy app (or site) to find the best deals on fuel near you.

Also note that depending on where you’re traveling, diesel may be cheaper than gasoline. Check GlobalPetrolPrices to compare the costs of different types of fuel so you can choose a rental car appropriately.
