Where to look for cheaper car rentals in Salt Lake City

The lowest rates in Salt Lake City usually come from comparing prices across multiple rental companies at once, rather than booking directly with one. Start by checking aggregator sites like Kayak, Autoslash, or Priceline, which pull rates from dozens of companies and let you sort by price. Then visit the websites of the major companies operating at Salt Lake City International Airport (Delta, Hertz, Enterprise, Budget, Avis, National) and a few regional ones like Fox Rent A Car or Thrifty, because occasionally a company runs a promotion that doesn't show up on aggregators.

The rental counter at the airport itself charges a 10 percent airport concession fee on top of the base rate, plus Utah's 6.85 percent sales tax. If you rent from an off-airport location — downtown Salt Lake City, near the University of Utah, or in nearby suburbs — you avoid the concession fee but may pay more for the car itself. Do the math on both before booking: sometimes the airport rate plus the fee is still cheaper than the off-airport rate without it.

Timing matters more than you might expect. Rates drop on weekdays and rise sharply on weekends and holidays. If your travel dates are flexible, moving your rental by even one day can cut your cost by 20 to 40 percent. Booking further in advance usually locks in lower rates, though some companies offer last-minute deals if demand is low.

Key Takeaways

  • Aggregator sites like Kayak and Autoslash show prices from multiple companies at once, which is faster than checking each one individually.
  • Renting from an off-airport location saves the 10 percent airport concession fee, but compare the total cost because the base rate may be higher.
  • Weekday rentals cost significantly less than weekend rentals, so shifting your dates by one or two days can save money.
  • Major companies at Salt Lake City International Airport include Delta, Hertz, Enterprise, Budget, Avis, and National, plus regional options like Fox Rent A Car.

Discounts and membership programs that actually reduce your rate

If you belong to AAA, AARP, or a military branch, mention it when you book — these memberships often unlock 10 to 20 percent discounts with major rental companies. The discount code is usually printed on your membership card or available through the organization's website. Enter it during checkout, and the rental company will verify your membership before you pick up the car.

Credit card companies sometimes offer rental car discounts or waived insurance through their rewards programs. Check your card's benefits guide or call the issuer before you book. Some cards also provide primary collision damage waiver coverage, which means you may not need to pay the rental company's insurance add-on — a savings of $15 to $30 per day.

Corporate codes work if your employer has a negotiated rate with a rental company. Ask your HR department or travel coordinator whether your company has an account. These codes are usually better than public discounts, though they require you to rent under your company name.

Insurance and damage waivers: what you actually need to pay for

The rental company will offer you damage waiver coverage (called Loss Damage Waiver or Collision Damage Waiver) at the counter. This costs $12 to $35 per day and covers damage to the rental car. Before you buy it, check whether your personal auto insurance or credit card already covers rental cars — most do. Call your insurance company or credit card issuer before your trip to confirm the coverage limits and what you have to do to make a claim.

If your personal insurance or credit card covers rentals, you can decline the rental company's waiver and save that daily fee. If neither covers rentals, or if the coverage is limited, buying the waiver from the rental company is cheaper than paying out of pocket for damage. Keep the receipt and any damage documentation if you need to file a claim later.

Liability insurance (covering injury or damage you cause to other people or property) is required by law in Utah. Your personal auto insurance usually covers this in a rental car, but confirm it before you book. If you don't have personal auto insurance, you must buy liability coverage from the rental company.

Fuel options and how to avoid overpaying

Rental companies offer three fuel options: prepay for a full tank at their rate, return the car with a full tank and pay their rate for any missing fuel, or return it empty and pay their per-gallon rate for fuel you didn't use. The prepay option sounds convenient but is almost always the most expensive — rental companies charge $6 to $8 per gallon, roughly double the local pump price.

The best strategy is to return the car with a full tank yourself. Before you pick up the rental, note the location of gas stations near the airport or your return location. Fill up at a regular gas station the morning you return the car, then drive straight to the rental return lot. This costs you only the actual fuel price, not the rental company's markup.

If you return the car empty, the rental company will charge you their per-gallon rate for the entire tank, which is always more than you would pay at a pump. Avoid this option unless you have no other choice.

Car type and size: what actually costs less

Economy and compact cars rent for less than midsize or full-size vehicles, but the difference is often smaller than you expect — sometimes only $5 to $10 per day. If you need more space or comfort for a longer trip, the upgrade may be worth it. Check the price for each size category before you decide based on what you think you need.

SUVs and trucks cost significantly more and use more fuel, so avoid them unless your trip genuinely requires one. If you're renting for a week or longer, the daily rate drops for all vehicle types, so a larger car might become competitive with a smaller one.

Some rental companies offer hybrid or electric vehicles at a similar rate to gas cars, and they cost less to fuel. If one is available in your size category, compare the total fuel cost over your trip — the savings can offset a slightly higher rental rate.

Rental length and weekly rates

Rental companies charge by the day, but the daily rate drops significantly if you rent for a week or longer. A three-day rental might cost $25 per day, but a seven-day rental might cost $18 per day — a 28 percent savings. If your trip is close to a week boundary, renting for the longer period can be cheaper than renting for the exact number of days you need.

Monthly rentals drop even further, sometimes to $12 to $15 per day with major companies. If you need a car for more than two weeks, ask about monthly rates explicitly, because the aggregator sites don't always show them.

What to check before you complete your booking

Before you click "confirm," verify the pickup and return locations, dates, and times. Returning a car late — even by an hour — can trigger an extra day's charge. If you're unsure about your return time, book for an extra day and cancel it later if you don't need it; most companies allow free cancellation up to 24 hours before pickup.

Read the terms for mileage limits. Most rentals in Utah are unlimited mileage, but some budget companies cap it at 100 to 150 miles per day and charge $0.25 to $0.50 per mile over that. If you're driving to Moab, Park City, or anywhere more than 100 miles away, confirm that unlimited mileage is included.

Check the age requirement. Most companies rent to drivers 21 and older, but drivers under 25 pay a daily surcharge of $15 to $25. If you're under 25, factor this into your total cost.

Frequently Asked Questions

Is it cheaper to book through a travel website or directly with the rental company?

Travel websites usually show lower rates because they negotiate volume discounts, but occasionally a rental company runs a promotion only on its own website. Check both, but start with an aggregator site because it saves you time comparing multiple companies.

Can I negotiate the price at the rental counter?

Prices are set by the company's system and rarely negotiable, but if you find a lower rate online while you're at the counter, show it to the agent — some will match it. Discounts from memberships or corporate codes can still be applied at pickup if you didn't enter them during booking.

What happens if I return the car damaged?

The rental company will document the damage and charge you through the damage waiver or your insurance. Take photos of the car's condition before you leave the lot so you have proof of its state when you picked it up. If you bought the rental company's damage waiver, the charge is covered.

Do I have to rent from the airport, or is downtown cheaper?

Downtown and off-airport locations avoid the 10 percent airport concession fee, but the base rate is often higher. Compare the total cost for both locations before booking — sometimes the airport rate plus the fee is still lower than the off-airport rate without it.

What if I need to extend my rental after I've picked up the car?

Call the rental company as soon as you know you need extra days. They'll extend your reservation and charge you the rate for those additional days, which may be higher than your original daily rate. Extending early is usually cheaper than returning late and renting again.
