How to calculate road trip fuel stops
This calculator finds the number of fuel stops needed for a road trip, based on trip distance, usable tank capacity, and fuel economy — assuming a full tank at the start.
How the calculation works
Fuel stops = max(0, ceil(Trip distance ÷ (Tank capacity × MPG)) − 1). The −1 accounts for starting with a full tank, so the first tank's worth of range doesn't require a stop.
Example
A 900-mile trip with a 15-gallon tank and 30 MPG (450 miles of range per tank): max(0, ceil(900÷450)−1) = max(0, 2−1) = 1 stop.
Frequently asked questions
How is Result calculated?

Pro Tips for Road Trip Fuel Stops
- This assumes starting with a completely full tank — adjust your planning if you'll be starting with a partial tank.
- Real-world driving conditions (terrain, speed, load) can reduce achievable range below the EPA-rated MPG figure used in this calculation.
Common Road Trip Fuel Stops Mistakes to Avoid
- Not accounting for a partial starting tank if that's your actual situation, since this formula assumes a full tank at departure.
