Frequently Asked Questions
Why do rental car prices vary so much?
Prices vary based on vehicle type, rental duration, location (airport locations often have higher fees), season, insurance choices, and add-ons. Booking in advance and joining loyalty programs can help reduce costs.
Do I need rental car insurance?
It depends on your existing coverage. Your personal auto insurance and credit card may provide coverage. However, rental insurance offers peace of mind and protects against high deductibles. Check your existing policies before declining.
What is the young driver surcharge?
Most rental companies charge extra for drivers under 25 due to higher accident risk. Drivers under 21 pay the highest surcharge, while some companies won't rent to drivers under 21 at all.
Are one-way rentals more expensive?
Yes, one-way rentals typically cost $150-300 extra due to the logistics of returning vehicles to their original location. Dropping off in a different state is more expensive than within the same city.
Can I customize this calculator for my rental company?
Yes, you can adjust daily rates, add your vehicle fleet, modify insurance packages, and customize fees to match your pricing structure. Embed it on your website to help customers estimate costs.
