Renting a car for a day is straightforward if you follow a few key steps. Start by determining your vehicle needs and budget, then use comparison websites or apps to check prices from major rental companies. The most critical steps are comparing total costs (including fees), understanding the rental agreement, and inspecting the car thoroughly before you drive off. Here’s a quick comparison of daily base rates for an economy car from major companies, though prices fluctuate based on location and demand.
| Rental Company | Average Daily Rate (Economy) | Key Fee to Watch For | Recommended For |
|---|---|---|---|
| Enterprise | $45 - $65 | Early return fee | Customer service |
| Hertz | $50 - $70 | Additional driver fee | Wide selection |
| Avis | $48 - $68 | Underage driver fee | Business rentals |
| Budget | $42 - $60 | Fuel service fee | Budget-conscious |
| National | $55 - $75 | Airport concession fee | Convenience |
Your first decision is choosing the right vehicle. For a single day of city errands, an economy car is sufficient. If you're moving a few items or traveling with a group, a midsize SUV offers more space. Use an aggregator site like Kayak or Rentalcars.com to see real-time prices from multiple companies at once. This saves you from visiting each website individually.
Always look beyond the advertised daily rate. The final price includes taxes, airport concession fees (if applicable), and potential charges for additional drivers or young drivers (under 25). If you decline the rental company's Collision Damage Waiver (CDW), also known as Loss Damage Waiver (LDW), ensure your personal auto insurance or credit card provides adequate coverage for rental cars. This can save you a significant amount per day.
Before leaving the lot, conduct a brief inspection. Check for any existing dents, scratches, or interior stains and point them out to an agent to be documented on your rental agreement. Confirm the fuel policy—most companies use a "full-to-full" policy, meaning you return the car with a full tank to avoid high refueling charges. Finally, familiarize yourself with the car's controls to ensure a safe and comfortable day on the road.

I just rent through the Costco Travel website if I need a car for a day. Their prices are almost always lower than going direct, and they include a second driver for free. I pick a location away from the airport to avoid those extra fees. The whole process takes maybe 10 minutes online. I show up, they have my reservation, I do a quick walk-around the car to check for damage, and I’m on my way. Easy.

For a business trip where I only need a car for one day, my priority is speed and convenience. I book directly with National Car Rental using my Emerald Club membership. I can bypass the counter and go straight to the "Emerald Aisle" at the airport, choose any car in the section, and drive off. I expense everything, so I take the included liability insurance but rely on my corporate card's CDW. The key is minimizing time spent at the rental facility.

My main focus is keeping the cost down. I start by comparing prices on Kayak about a week beforehand. I always set the filter to show the total price with all taxes and fees—the initial quote is misleading. I stick with a compact car; it’s cheapest and easiest to park. I never get the extra insurance they try to sell you because my credit card covers it. I also make sure to fill up the tank right before returning it to avoid their crazy gas prices.

Think about what you'll actually be doing that day. Just running to a few stores in the suburbs? A small car is fine. Heading into a busy city? Consider the cost and stress of parking a larger vehicle. If it's a special occasion, maybe the splurge for a nicer model is worth it for the experience. Check the weather forecast; you might want something with all-wheel drive if conditions are iffy. Your one-day rental should fit the day's agenda, not just your budget.
