The advertised price rarely tells the whole story with car rentals. Here's a complete breakdown of every hidden fee you might encounter — and how to avoid each one.
Collision Damage Waiver (CDW)
This is the biggest upsell. CDW can double your rental price at the counter. Check whether your credit card or travel insurance already covers this before you leave home.
Young Driver Surcharge
Drivers under 25 (sometimes under 30) typically pay a daily surcharge of $10–$35/day on top of the base rate. Factor this in when comparing prices.
Additional Driver Fee
Each extra driver typically costs $10–$15/day. Some companies waive this for spouses — ask at the counter.
One-Way Fee
Renting in one city and dropping off in another triggers a one-way fee that can be substantial ($50–$200+). Compare options before booking a one-way trip.
GPS and Child Seat Rentals
In-car GPS is usually $10–$15/day — use your phone instead. Child seats are similar. Bring your own if possible.
Airport Surcharges
Airport locations tack on a concession fee recovery surcharge of 10–30%. Consider picking up from an off-airport location to avoid this.
Toll Charges and Administration Fees
Some companies charge an administration fee on top of any tolls you incur. Using a pre-paid toll pass can be more expensive than paying tolls directly.
Fuel Pre-Purchase
If you accept the 'full-to-empty' fuel option, you'll pay for a full tank at inflated prices and be expected to return the car empty. This almost never works out in your favour.
Out-of-Hours Fees
Picking up or dropping off outside business hours can trigger surcharges. Book a time within normal operating hours when possible.
Cross-Border Fees
Planning to drive into a neighbouring country? Many rental agreements prohibit this entirely, or charge $50–$100+ for cross-border permission.
