North Carolina → Florida · Interstate 85 / Interstate 77
What does it actually cost to drive from Charlotte, North Carolina, to Jacksonville, Florida? The hard numbers: 648 km (403 miles) of pavement primarily along Interstate 85 / Interstate 77, 6h 10m behind the wheel, and roughly $54.19 in fuel alone — that is 58.9 liters (15.6 gallons) of regular unleaded at a 0.92 USD/liter benchmark. Anyone leaving Charlotte, the Queen City of the Carolinas and the second-largest US banking center, typically carries samples, signed proposals, or service equipment to deliver in Jacksonville, the largest US city by area in the contiguous states and a major Atlantic naval port, 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 $278.64. 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.
