Actual fuel usage varies with driving style, traffic, terrain, and vehicle load. Use this as an estimate for trip budgeting.
How the Fuel Cost Calculator Works
This calculator estimates how much fuel a trip will consume based on your vehicle's efficiency rating, then multiplies that by the fuel price to estimate total cost.
Formula
Fuel Needed (L/100km mode) = (Distance ÷ 100) × L/100km
Total Cost = Fuel Needed × Price per Unit
Cost per Mile/km = Total Cost ÷ Distance
Why Track Fuel Cost?
Knowing your cost per mile or kilometer helps with trip budgeting, comparing vehicles, and deciding whether a road trip or flight is more economical.
Worked Example
For a 250-mile trip in a vehicle rated at 28 MPG, fuel needed is 250 ÷ 28 ≈ 8.93 gallons. At $3.50 per gallon, the total trip cost comes to $31.25, which works out to $0.125 per mile.
Frequently Asked Questions
How accurate is this fuel cost estimate?
It's a close estimate based on your vehicle's average efficiency rating. Actual costs can vary with driving style, traffic, terrain, weather, and cargo load.
Can I use this for L/100km vehicles?
Yes. Switch the efficiency unit to L/100km and enter your vehicle's rating along with the price per liter to get an equivalent estimate.
What is cost per mile used for?
Cost per mile (or kilometer) is useful for comparing the running cost of different vehicles or estimating mileage reimbursement for business trips.
