Book online, decline the coverage you already have, and fill the tank yourself before the return. U.S. regular gasoline averaged $4.331 per gallon in the week of October 12, 2026, so a pump near the depot beats the rental company's fuel rate almost every time. Skip the prepaid fuel option and the counter's insurance pitch.
The number on the search screen is a floor, not the price. The Federal Trade Commission's consumer guide to renting a car lists the ways a bill grows: airport surcharges, fuel penalties, waiver costs, and charges for extra drivers. Every line has a fix, and most take two minutes at home.
What Does the Advertised Rate Leave Out?
Rental quotes compete on a daily rate. The total at the counter tells a different story. Airport concession fees apply even when the company runs a shuttle to an off-site lot, according to the FTC. Hand the car back more than a day early and an early-return fee can land. Late returns can roll into another full day, with a day's charge for optional extras too.
- Airport surcharges, applied even at off-site lots served by shuttles
- Early-return fees when the car comes back more than 24 hours ahead of schedule
- Late charges that can include a full day's rate for optional items
- Drop fees for one-way routes and extra charges for out-of-state travel
Which Insurance Do You Already Have?
The damage waiver is the biggest single upsell. The FTC notes that a personal auto policy or a homeowner's policy may already cover a rental, and that some credit cards include free rental protection when the card pays for the booking. Card coverage usually carries a catch: it applies only if the counter's collision damage waiver is declined.
Read the fine print on both. A waiver covers damage to the car. It will not pay for injuries or for damage to personal property. Decline everything without a backup policy and the full value of the car sits on the card you handed over.
How Do Fuel Policies Drain the Budget?
Fuel is where inattention gets expensive. Most companies expect a full tank at return, and the FTC warns that the rental company's pump price usually runs higher than the local station's. A prepaid fuel plan sounds convenient. The FTC puts it plainly: it could be a lot more expensive than filling up yourself.
With U.S. regular gasoline averaging $4.331 per gallon in the week of October 12, 2026, per the Energy Information Administration, a 14-gallon tank costs about $61 at a street pump. The same tank billed at depot rates climbs from there. Go full-to-full, and keep the fuel receipt until the keys are handed back.
Should You Book Early or Pay at the Counter?
Compare totals, not day rates. The FTC's opening advice is to price the whole package, because fees and options pile onto the base price. A prepaid reservation can look cheaper. It can also carry cancellation fees no matter when plans change, and sale prices sometimes come with blackout dates.
Flexibility has a price too. Standard reservations usually cancel free further out, sometimes as much as a week ahead. One more check: many companies screen driving records, and a recent violation can end a confirmed booking.
Which Counter Fees Can You Refuse?
Some fees are policy and some are pitch. The extras below show up at the desk, and most have a cheaper workaround:
- Young driver fees. The minimum age to rent is 25, and most major companies rent to younger drivers for a fee. Compare that fee across companies
- Additional driver charges. Some companies charge to add a second driver to the contract. Rules vary; ask ahead
- Equipment rentals. Car seats, ski racks, and bike racks cost extra per day. Reserve ahead
- Toll programs. Per-day service charges or per-toll fees stack on top of the tolls. Read the schedule before signing
Conclusion: Read the Total, Then Sign
Every one of these car rental tips points at the same habit: price the total before the trip and again at the desk. Decline coverage that exists elsewhere. Fill the tank at a street pump. Photograph the odometer and the body panels at both ends. Readers following this should also see Travel Planning Guide — The Beginner's Guide to Planning Any Trip: A Step-by-Step Framework.
Then wipe the phone data from the infotainment screen. The FTC advises clearing personal data from the system before the keys go back, since paired phones leave contacts and messages behind. Two minutes in the settings menu ends the rental clean. We covered a connected angle in How Much Can You Bring Back From Shopping Abroad Before US Customs Charges Duty?.
