What is the cost of driving a given distance?
The Driving Cost Calculator combines distance, vehicle MPG, and fuel price to estimate the total fuel cost of any drive. Use it to decide whether driving or flying is cheaper, split gas costs between passengers, or compare commute costs between different vehicles.

How it works
Driving Cost Calculator: inputs, formula, and result
Enter the values that describe your trip planning scenario. The interactive result changes as the inputs change, helping you compare fuel efficiency, fuel consumption, fuel cost, or operating impact.
Formula
Driving Cost = (Trip Distance ÷ Vehicle MPG) × Fuel Price
Worked example
A 360-mile drive at 30 MPG with gas at $3.50/gallon costs (360 ÷ 30) × 3.50 = $42.00.
Pro tip: When comparing driving vs. flying, add parking, tolls, and wear-and-tear costs (roughly $0.10-$0.15 per mile) to the fuel cost for a fair comparison.

FAQ
FAQs about Driving Cost
3 questions
Question 1 of 3 is open
What is the average cost per mile to drive?
Fuel alone costs $0.10-$0.18 per mile for most cars at $3.50/gallon and 20-35 MPG. AAA estimates the total cost of vehicle ownership at $0.60-$0.90 per mile including all expenses.
Is it cheaper to drive or fly for a 500-mile trip?
For a solo traveler, flying is often cheaper for trips over 300-400 miles. For families of 3+, driving is usually cheaper since fuel cost is shared but each airline ticket is separate.
How do I split driving costs fairly between passengers?
Divide the total fuel cost by the number of passengers including the driver. For a $100 fuel bill split 4 ways, each person pays $25.
