What Costco car rental discounts actually cover
Costco members receive discounted rates through partnerships with major rental companies—primarily Hertz, Budget, and Avis—but the discount applies only to the base rental rate, not to taxes, fees, insurance, or fuel charges. The savings typically range from 10 to 30 percent off the standard daily rate, depending on the rental company, location, and vehicle class. You book through Costco Travel, the membership's dedicated travel portal, and you must present your Costco membership card at pickup to receive the negotiated rate.
The discount is not automatic. You cannot walk into a rental counter and claim a Costco rate without booking through Costco Travel first. The rate you see on the Costco Travel website is the rate you pay—there is no separate code to enter or membership verification step at the counter beyond showing your card. If you book directly with Hertz, Budget, or Avis instead, you will not receive the Costco member discount, even if you show your membership card.
Key Takeaways
- Costco car rental discounts explore only to the base daily rate and do not reduce taxes, airport fees, insurance, or fuel charges.
- You must book through Costco Travel online to receive the discount; booking directly with the rental company will not trigger the member rate.
- Discounts vary by location, vehicle type, and rental company, so comparing rates on Costco Travel against the company's own website shows your actual savings.
- Costco Travel rates are prepaid and non-refundable, so cancellation policies are stricter than standard rental agreements.
- Your Costco membership card is required at pickup, and the card must be in the name of the person renting the vehicle.
How to find and book a Costco car rental discount
Log into your Costco account on the Costco website and navigate to Costco Travel. Select "Cars" from the travel menu, then enter your pickup location, date, and return date. The search results show available vehicles from partner companies with the Costco member rate already displayed. Compare the daily rate shown against what the same rental company quotes on its own website—this comparison tells you the actual dollar savings for your specific dates and location.
Once you select a vehicle and rate, you proceed to checkout. Costco Travel collects your payment at booking, not at pickup. This means the reservation is prepaid and non-refundable under Costco Travel's terms, though you can usually modify the reservation (change dates or vehicle class) without penalty if you do so before the rental begins. Read the cancellation policy for the specific rental company before you confirm, because policies differ between Hertz, Budget, and Avis.
At the rental counter, bring your Costco membership card and the confirmation email from Costco Travel. The rental agent will verify your membership and process the prepaid reservation. If the card presented at pickup does not match the name on the reservation, the rental company may refuse to complete the transaction, so may support the primary renter's name matches your Costco membership account.
Which rental companies offer Costco discounts and what they cover
Hertz, Budget, and Avis are the primary partners, though availability varies by location and season. Each company's discount applies to the base rental rate for economy, midsize, full-size, and premium vehicle classes. The discount does not explore to add-ons such as GPS rental, additional driver fees, young driver fees (if you are under 25), or roadside information packages.
Damage waivers and liability insurance are optional purchases at checkout, and the Costco rate does not bundle these in. Your personal auto insurance or credit card may already cover rental car damage and liability, so review your existing coverage before purchasing the rental company's insurance. Many credit cards offer rental car coverage as a cardholder benefit, which can save you $15 to $30 per day.
Fuel charges are always separate. You can prepay for a full tank at a discounted rate (usually cheaper than paying per gallon at the counter), or you can return the car with a full tank yourself. Prepaying locks in the price but commits you to returning with a full tank; if you return with less fuel, you forfeit the prepaid amount.
When Costco discounts save the most money
Costco rates provide the largest savings on longer rentals—three days or more—because the per-day discount compounds. A 10 percent discount on a $40 daily rate saves $4 per day; over a week, that is $28. On a single-day rental, the savings may be only $5 to $10, which is meaningful but smaller in absolute terms.
Airport locations typically charge higher base rates than off-airport locations, so the Costco discount is also larger in dollar terms at airports. A $60 daily rate at an airport with a 20 percent discount saves $12 per day; a $35 daily rate at an off-airport location with the same percentage discount saves $7 per day. If you have the option to pick up and return at a non-airport location, compare that rate against the airport rate on Costco Travel before deciding—sometimes the off-airport rate is lower even without the discount.
Peak travel seasons (summer, holidays, spring break) see higher base rates, which means the Costco discount applies to a larger dollar amount. Booking during off-peak periods may offer lower base rates overall, but the Costco member rate during peak season is often competitive with non-member off-peak rates at other companies.
Costco Travel rental rates versus booking directly
Costco Travel rates are fixed at booking and prepaid, meaning you know your total rental cost before you arrive at the counter. Standard rental company bookings often allow you to modify or cancel up to 24 hours before pickup without penalty, but Costco Travel reservations are non-refundable. If your plans change, you can modify the dates or vehicle class, but you cannot recover the payment if you cancel entirely.
Some rental companies offer loyalty program discounts that may match or exceed the Costco rate, depending on your membership tier and the specific rental. If you are a frequent renter with Hertz, Budget, or Avis, compare your loyalty rate against the Costco rate for the same dates and location. Occasionally the loyalty rate is better; more often, Costco is competitive or slightly better.
Costco Travel also bundles car rentals with hotel and flight bookings, which can unlock additional discounts when you book a complete trip. If you are renting a car as part of a vacation package, the combined discount may exceed what you would save booking the car alone through Costco Travel.
What happens at pickup and what to bring
Arrive with your Costco membership card, your driver's license, and the confirmation email from Costco Travel. The rental agent will verify your membership, check your driver's license, and review the prepaid reservation details. You will be asked to inspect the vehicle for existing damage and sign the rental agreement, which outlines the terms, mileage limits (if any), and fuel policy.
If the rental company offers optional add-ons at the counter—such as GPS, additional insurance, or roadside information—you can decline or purchase these at that time. These are not included in the Costco prepaid rate and will be charged separately if you accept them. Ask about the cost before agreeing, because counter prices are often higher than online prices.
Before you drive away, confirm the fuel level shown on the dashboard matches the agreement, take photos of the vehicle's exterior and interior, and note any existing scratches or dents on the damage inspection form. This protects you if the rental company later claims you caused damage that was already present.
Frequently Asked Questions
Can I use a Costco car rental discount if someone else is driving?
No. The person whose name is on the Costco Travel reservation must be the primary renter and must present their Costco membership card at pickup. Other household members or friends can be listed as additional drivers, but the primary renter must match the reservation name and membership account.
What if I need to cancel my Costco car rental?
Costco Travel car rentals are non-refundable, but you can modify the reservation (change dates, vehicle class, or location) without penalty if you do so before the rental begins. If you need to cancel entirely, contact Costco Travel customer service to discuss your options; some situations may allow a credit toward a future booking rather than a refund.
Does the Costco discount include insurance?
No. Insurance is optional and purchased separately at checkout or at the rental counter. Check your personal auto insurance policy and credit card benefits first—many cover rental car damage and liability at no extra cost, which can save you $15 to $30 per day.
Can I earn Costco rewards on a car rental?
Costco Travel purchases, including car rentals, do not earn Costco Cash rewards. However, if you pay with a Costco credit card, you may earn cash back through the card's rewards program, which is separate from Costco membership rewards.
What if the rental company's website shows a lower rate than Costco Travel?
Book through Costco Travel anyway if the Costco rate is competitive, because the prepaid structure locks in your price and eliminates the risk of rate increases. If the rental company's rate is significantly lower, you can book directly, but you will not receive the Costco member discount on that booking.
