Why Understanding Rental Costs Matters

Knowing how daily fees and per-mile charges work helps travelers budget accurately and avoid hidden charges. Always check if insurance, add-ons, or early returns affect the total. With clear pricing, renting saves time and ensures a stress-free journey.

Whether you’re renting locally or for a road trip, calculating costs ahead of time empowers smarter decisions. For Sarah’s trip, the total comes to just $165—simple, predictable, and far cheaper than many expect.

Pro tip: Always confirm pricing with your rental provider before signing—transparency saves money!
