On average, car rentals in Casper cost around $72 per day, with the lowest-priced rentals starting at $41 per day.
Compare airport vs downtown pickups: downtown Casper usually skips the 10 % airport surcharge. Even after a $20–30 rideshare from CPR you can still come out ahead on longer rentals.
Shift your dates: weekday pickups/returns are often cheaper than weekends. Moving your reservation by just a day can drop the rate.
Traveling 5+ days? Check weekly rates—often lower than paying the daily price for the same period.
Season matters: winter (outside Christmas/New Year) is low-demand and cheaper. For busy June–August runs, lock in 1–2 months out before vehicles get scarce.

What documents do I need to rent a car in Casper? You'll need a valid driver's license and a credit card in your name. If you don't buy the rental company's collision coverage, they might ask to see proof of your own car insurance. Visitors from other countries need to bring a passport and a valid driver's license from their home country. We also recommend an International Driving Permit. You must have one if your license isn't in English.
Are 4WD/AWD vehicles necessary in Casper? In the summer, any type of car will work fine. For winter travel between November and March, we highly recommend getting an AWD or 4WD vehicle to help you drive on snowy and icy roads.
What is the minimum age to rent a car in Casper? Most rental companies need you to be at least 21 years old. If you're under 25, they will add a young driver fee of about $25-30 each day.
Can I pick up a rental car in Casper and drop it off in another city? Yes, you can rent a car one-way, but companies usually charge extra for it. Popular drop-off cities include Jackson, Cheyenne and Denver. The fees are between $100 and $300, based on how far you drive.
What fuel type do rental cars in Casper use? Most rental cars use regular unleaded gasoline. In Wyoming, 85-87 octane is standard because of the higher elevation. You can sometimes find diesel options for certain truck models, but they are less common.
