Mileage Reimbursement vs. Car Rental Calculator

Employee Travel: Should You Rent a Car or Reimburse Miles? 

As companies realize the many benefits of renting a car instead of encouraging employees to drive their personal vehicles when they need to travel for work, you may be wondering whether it is the right choice for your business. Use our car rental and mileage reimbursement calculator to see the difference working with Enterprise can make for your travel budget in just a single trip. 

Rental Car Benefits 

  • Saving Money. By renting vehicles (often at discounted corporate rates), businesses can frequently cut costs. On average, rentals cost 55¢ a mile, while the IRS rate is set at 70¢ for 2025, offering a savings of more than 25%.1 
  • Managing Risk & Duty of Care. With a recent-model rental, you get peace of mind knowing the vehicle technology is current and maintenance is up to date. 
  • Protecting Your Brand Image. Choosing a rental car from Enterprise helps ensure your employees travel — and meet clients, partners and vendors — in a clean, well-maintained and regularly serviced vehicle.

Glossary

Travel Distance is the total roundtrip mileage by car to and from your destination. Google Maps™ mapping service can help you estimate this distance. 

Fuel Cost is the current price per gallon of gas. AAA® is a good resource to use when looking for the current prices for your travel area(s). If your travel takes you through areas with varying costs, averaging them can provide a helpful estimate. 

Reimbursement Rate is the amount per mile that your company uses when reimbursing employees for travel in personal vehicles. Many organizations choose to use the IRS standard business rate, an amount reviewed and often adjusted annually, which we’ve entered for you, but if your company uses an alternative rate, enter that instead.
