Introduction
The Trip Cost Calculator shows you what a road trip will really cost before you leave. Type in where you start and where you are going, add stops along the way, and pick your car. The tool adds up gas or charging, tolls, parking, hotels, food, wear on your car, and driver pay. Then it splits the total by how many people are riding.
The tool does not look up real roads. It estimates road distance as the straight-line distance between your stops multiplied by a road factor you can change, or you can enter your own driving distance. For tolls, enter the total for your route; our toll calculator prices several toll roads from their operators' published tables.
The calculator works with miles or kilometers, and with 18 currencies. Pick your fuel type, from regular gas to diesel to electric. Look up your exact year, make, and model to auto-fill the MPG.
You also get a full cost table, a step-by-step math breakdown, a cost chart, and a simple schematic map of your stops. Change any number and the results update right away, so you can test different plans and find the best trip cost for your budget.
How to use our Trip Cost Calculator
Enter your route, your vehicle, and your extra travel costs. The trip cost calculator then shows your road trip distance, drive time, fuel or energy use, tolls, and the total cost per trip, per person, and per mile.
Trip Mode: Pick One Way if you drive there only. Pick Round Trip to double the distance for the drive back.
Unit System: Choose US/Imperial for miles and gallons, or Metric for kilometers and liters. Your entered numbers are converted for you.
Road Distance Factor: The tool multiplies the straight-line distance between your stops by this number to estimate road distance. It starts at 1.20; raise it for winding routes or lower it toward 1 for direct highways. It is not used when you enter your own distance.
Origin: Type your start city. You can also type "lat, lon" or tap the location button to use your current spot.
Swap button: Click it to trade your origin and destination places.
Destination: Type the city where your trip ends.
Intermediate Stops: Click Add Stop for each place you visit on the way. Drag the handle or use the arrow buttons to change the order. With 3 or more stops, click Optimize Stop Order to find a shorter path.
Enter one-way road distance manually: Tick this box if you already know your driving distance. The map and per-leg table turn off when you use it.
Manual One-Way Distance: Type the one-way distance and pick miles or kilometers.
Vehicle Type: Choose car, pickup, motorcycle, RV, bus, or truck. This sets default fuel use and average speed.
Axles: For trucks only, pick how many axles you have. It scales the vignette charge for trucks.
Fuel / Energy Type: Pick regular gas, midgrade, premium, diesel, E85, UNL88, LPG, CNG, or Electric. This sets a default price.
Year, Make, Model, Trim: Pick your car from the list to auto-fill its MPG and tank size. This step is optional.
City Efficiency: Enter your gas mileage in town, or let the vehicle list fill it in.
Highway Efficiency: Enter your gas mileage on the highway.
Efficiency Unit: Choose MPG (US), MPG (UK), L/100 km, or km/L. Electric cars show mi/kWh and kWh options.
Highway Driving Mix: Enter the percent of your trip on the highway. The rest counts as city driving.
Tank / Battery Capacity: Enter your fuel tank size or battery size. This tells you how many fuel or charging stops you need.
Fuel / Energy Price: Enter what you pay per gallon, liter, or kWh.
Tolls (total): Enter the tolls for your whole trip, if any. They are added to the total as you enter them.
Display Currency: Pick the money you want to see. All money fields you typed are converted too.
Parking Fees: Enter the total parking cost for the whole trip.
Lodging per Night: Enter the price of one hotel night.
Nights: Enter how many nights you stay.
Meals per Day: Enter what one person spends on food each day.
Days: Enter how many days you eat on the road.
Auto-estimate nights & days: Leave this ticked to let the tool guess nights and days from drive time, using about 8 driving hours per day.
Vehicle Depreciation / Wear Rate: Enter the wear and tear cost per mile or km. Use 0 to skip it.
Driver / Labor Cost per Hour: Enter an hourly pay rate if you pay a driver. Use 0 if not.
Number of Passengers: Enter how many people ride along. This splits the total trip cost per person.
Show distances in: Choose miles or kilometers for your results, map, and cost per distance.
Calculate Trip Cost: Click it to see the trip estimate, the cost breakdown, step-by-step math, the cost chart, and the stops map. Click Reset to start over with sample values.
Trip Cost Calculator: What It Covers
A road trip costs more than gas. The real price of driving from one city to another includes fuel or charging, tolls, parking, food, hotels, and the wear you put on your car. Adding all of these up gives you the true cost per trip, per mile, and per person.
What Goes Into a Trip's Cost
- Fuel or energy: How far you drive, how much your car uses, and the price per gallon, liter, or kWh.
- Tolls: Fees charged at bridges, tunnels, and toll roads. Rates change by vehicle size and number of axles.
- Vignettes: In many European countries you buy a sticker or pass before using highways instead of paying at booths.
- Parking: Garage or lot fees at your stops and at the end point.
- Lodging and meals: Long drives need overnight stops. The auto-estimate assumes about 8 hours of driving per day.
- Wear and depreciation: Tires, oil, brakes, and lost car value. Enter your own per-mile figure, or 0 to leave it out.
- Driver time: If you pay a driver, hours behind the wheel are a real cost.
Why Road Distance Is Longer Than Map Distance
Roads curve, so the driving distance is always longer than the straight line between two cities. This tool finds the straight-line distance with the haversine formula of spherical trigonometry.4 It then multiplies that by the road distance factor you set, 1.20 unless you change it.
City vs. Highway Fuel Use
Cars burn fuel differently in stop-and-go traffic than on open highways. Gas cars usually do better on the highway. Electric cars use regenerative braking to recapture energy that would be lost in braking, and counting that energy, their efficiency can exceed 94% in the city and 77% on the highway.3 That is why your highway-versus-city mix changes the answer. Your average speed matters too, since steady cruising uses less fuel than constant braking.
Tolls
Toll rates depend on the road, where you enter and leave it, your vehicle class, and how you pay, so this tool does not estimate them. Enter the total for your route in the Tolls field. For an exact toll, use the toll road operator's published toll schedule.
Splitting Costs for Carpools and Rideshares
When you share a ride, the total cost divides across everyone in the car. Two riders cut the price per person in half. This is why carpooling is one of the cheapest ways to travel long distances. A fair split covers fuel, tolls, and parking, and some drivers also add a small amount for wear on the car. Before you drive, compare the split against an Uber fare to be sure driving still wins.
Ways to Lower Your Trip Cost
- Compare fuel prices before you fill up.
- Get a toll transponder for the region you drive in most.
- Drive at a steady speed; gas mileage usually decreases rapidly at speeds above 50 mph1.
- Keep tires at the right pressure: under-inflation lowers gas mileage by about 0.2% for every 1 psi drop2.
- Take off roof-top cargo boxes you do not need; they add drag and lower fuel economy1.
- Plan stops in the smartest order so you do not backtrack.
- Share the drive with passengers to split every cost.
