Florida → Florida · Interstate 95 / Interstate 10
What does it actually cost to drive from Jacksonville, Florida, to Miami, Florida? The hard numbers: 623 km (387 miles) of pavement primarily along Interstate 95 / Interstate 10, 5h 56m behind the wheel, and roughly $52.07 in fuel alone — that is 56.6 liters (15.0 gallons) of regular unleaded at a 0.92 USD/liter benchmark. Anyone leaving Jacksonville, the largest US city by area in the contiguous states and a major Atlantic naval port, typically carries samples, signed proposals, or service equipment to deliver in Miami, the leading US gateway to Latin America and the Caribbean tourism market, 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 $267.89.
