Nevada → Utah · Interstate 15
What does it actually cost to drive from Las Vegas, Nevada, to Salt Lake City, Utah? The hard numbers: 689 km (428 miles) of pavement primarily along Interstate 15, 6h 34m behind the wheel, and roughly $57.59 in fuel alone — that is 62.6 liters (16.5 gallons) of regular unleaded at a 0.92 USD/liter benchmark. Anyone leaving Las Vegas, the leading entertainment and conventions destination in the US Southwest, typically carries samples, signed proposals, or service equipment to deliver in Salt Lake City, the capital of Utah and the gateway to the Wasatch Range and the Great Basin, and aims to be home the same evening. It is worth confirming whether the haul fits inside your daily hours-of-service window or whether an overnight at a midpoint hotel makes more sense. Applying the IRS standard mileage rate (2025) mileage rate of $0.43/km ($0.69/mile), the gross outbound reimbursement settles at $296.27. Attach the visit purpose, client name, and plate number to the Clara receipt so the journal entry lands directly in the business-travel expense account.
