Where to look for lower rates in Salt Lake City

The cheapest car rentals in Salt Lake City usually come from comparing prices across multiple companies rather than booking with the first one you find. Major chains like Enterprise, Hertz, Budget, and Avis all operate at Salt Lake City International Airport (SLC) and downtown locations, and their rates for the same car can differ by $20 to $40 per day depending on when you book and what day you need it.

Start by checking aggregator sites like Kayak, Autoslash, or Priceline, which pull rates from many rental companies at once. Then visit the websites of individual companies directly — sometimes they show lower rates on their own sites than through third parties. Off-airport locations like those on South Temple or in the Sugar House neighborhood often charge less than the airport counter, though you'll need to factor in the cost and time of getting there.

Local and regional companies like Thrifty, Fox Rent A Car, and Advantage sometimes undercut the major chains, especially for longer rentals. Check their rates alongside the big names before you book.

Key Takeaways

  • Comparing rates across at least three different rental companies or aggregator sites typically saves $30 to $100 on a week-long rental.
  • Off-airport locations in Salt Lake City charge less than the airport counter, but add the time and transportation cost to your total before deciding.
  • Booking 2 to 3 weeks ahead usually costs less than booking a few days before, especially for weekend rentals.
  • Your credit card, auto insurance, or AAA membership may cover collision damage, which means you can decline the rental company's insurance and save $15 to $25 per day.
  • Fuel charges add up quickly; renting a compact or economy car instead of a midsize sedan can cut your gas cost by 30 percent on a week-long trip.

Timing your booking to get the best rate

The day of the week and the season matter more than most renters realize. Weekday rentals in Salt Lake City are typically cheaper than weekend ones, sometimes by 40 percent or more. If your trip is flexible, renting Monday through Thursday will almost always cost less than Friday through Sunday.

Booking 2 to 3 weeks in advance usually locks in a lower rate than waiting until a few days before you need the car. Prices tend to rise as the rental date gets closer, especially during ski season (December through March) and summer vacation months (June through August). If you're traveling during those peak periods, booking early is even more important.

One-way rentals — picking up in Salt Lake City and dropping off elsewhere — typically cost more than round-trip rentals. If you're planning a one-way trip, compare the one-way price to the cost of a round-trip rental plus a separate return flight or drive home.

Insurance and damage waivers: what you actually need

Rental companies push collision damage waivers (CDW) or loss damage waivers (LDW) hard, often quoting $20 to $30 per day. Before you buy, check whether your personal auto insurance or credit card already covers rental cars. Most standard auto policies and many premium credit cards cover collision and theft on rental vehicles, which means paying the rental company's insurance is money wasted.

Call your insurance company or credit card issuer before you rent and ask specifically: "Does my policy cover collision damage on a rental car?" Get the answer in writing if possible. If you're not covered and the rental company's insurance costs more than $15 per day, look for a different company — rates vary widely.

Decline the insurance only if you're certain you're covered elsewhere. If you cause damage and you're not insured, you'll pay the full repair bill out of pocket, which can easily exceed $1,000.

Car size and fuel strategy

Renting the smallest car that fits your needs saves money on both the daily rate and fuel. A compact car rents for $5 to $15 less per day than a midsize sedan and uses 20 to 30 percent less gas. If you don't need the extra space, skip the upgrade.

Most rental companies charge extra if you return the car with less than a full tank, and their per-gallon price is usually 50 to 100 percent higher than a gas station. Fill up at a station near the rental location before you return the car, not at the rental company's pump. Plan your route to avoid unnecessary driving, and use a GPS or phone map to find the most direct route.

Membership discounts and promotional codes

AAA members, AARP members, military personnel, and frequent business travelers often get discounts of 10 to 25 percent off the base rate. Ask about your membership status when you book, and enter any membership number you have into the booking form. Some rental companies also offer loyalty programs that accumulate points toward free rental days.

Check for promotional codes before you book. Rental companies run seasonal promotions — "rent for 4 days, pay for 3" or "20 percent off economy cars" — that you can find on their websites or through email newsletters. Signing up for a company's email list takes two minutes and often includes a first-booking discount code.

Corporate codes sometimes work even if you're not traveling for business. If you work for a large employer, check your company's intranet or benefits page for negotiated rental rates.

Airport versus off-airport locations

Salt Lake City International Airport charges a 10 to 15 percent facility fee on top of the base rental rate, plus airport taxes. An off-airport location on South Temple or in Sugar House will show a lower total price. However, you need to factor in the cost of getting there — a rideshare from the airport to an off-airport location costs $15 to $25, and the time adds 30 to 45 minutes to your rental process.

For a one-day rental, the airport location usually makes sense because the time and transportation cost outweigh the savings. For a week-long rental, an off-airport location can save $50 to $100 after you account for transportation. Calculate the total cost including your ride to the rental location before you decide.

What to check before you confirm the booking

Read the cancellation policy before you book. Most companies allow free cancellation up to 24 hours before pickup, but some charge a fee. If your plans might change, choose a company with free cancellation.

Check the mileage policy. Some companies offer unlimited mileage; others charge per mile after a certain threshold. For a week-long trip around Utah, unlimited mileage usually costs less than paying per mile, even if the daily rate is slightly higher.

Verify the fuel policy. Some companies charge a premium for returning the car on empty; others charge a flat fee if you don't return it full. Know which one applies before you pick up the car so you can plan accordingly.

Frequently Asked Questions

Is it cheaper to rent a car at the airport or downtown in Salt Lake City?

Downtown and off-airport locations show lower daily rates because they don't charge the airport facility fee. However, getting to an off-airport location costs $15 to $25 in rideshare fare. For a one-day rental, the airport is usually cheaper overall. For a week-long rental, an off-airport location often saves $50 to $100 after transportation costs.

What's the best day of the week to rent a car in Salt Lake City?

Weekday rentals (Monday through Thursday) cost 30 to 40 percent less than weekend rentals. If your trip is flexible, shifting your rental to a weekday will cut your total cost significantly. Peak season (ski season and summer) makes this difference even larger.

Do I have to buy the rental company's insurance?

No. Most personal auto insurance policies and premium credit cards cover collision damage on rental cars. Call your insurance company or credit card issuer before you book and ask if you're covered. If you are, declining the rental company's insurance saves $15 to $30 per day.

How far in advance should I book a car rental in Salt Lake City?

Booking 2 to 3 weeks ahead usually locks in the lowest rate. Prices rise as the rental date approaches, especially during ski season (December through March) and summer (June through August). If you're traveling during peak season, booking as early as possible matters more.

Can I use a promotional code with other discounts?

Sometimes. Most rental companies allow you to stack a promotional code with a membership discount, but not always. Enter both when you book and see what the final price shows. If the system won't accept both, contact the rental company to ask which discount is larger.
