Trip Cost Calculator

Estimate fuel, tolls, parking and other trip costs using your own amounts, with optional return travel.

Your vehicle and journey inputs

Prefilled measurements are editable examples. Prices and rates start at zero: unpriced, not local quotes. All fields are required unless marked optional. Results clear when inputs change. Unit changes convert current values; currency changes preserve numbers without exchange rates.

Currency labels only. Enter all prices and expenses in the selected currency. No exchange-rate conversion.

Enter tolls, parking and other expenses for the whole trip, including return travel.

Enter one-way distance when selecting round trip; otherwise enter total distance.

Use a positive average efficiency appropriate to your vehicle and journey.

Enter your own price. Default 0 is unpriced, not a local quote or free fuel.

Enter all legs combined; this is not doubled by the round-trip option.

Your total parking cost for the entire journey.

Blank = 0. Include any additional costs you want in the total.

Your estimate

Energy, fuel and costs

Review the editable example values, enter your own prices where needed, then calculate.

How much will a road trip cost including tolls and parking?

Trip distance = entered distance × 2 when round trip is selected, otherwise entered distance. Fuel cost uses the fuel-cost formula. Total = fuel cost + tolls + parking + optional other expenses. Nonfuel expenses are entered for the entire trip and are never automatically doubled.

Worked example

A 100 km one-way journey at 8 L/100 km uses 16 L for a round trip. With your illustrative price of 1.50/L, total-trip tolls of 10, parking of 5 and other expenses of 0, total is 39.00. Costs start at zero; enter your own quotes.

Unit conversions

1 mile = 1.609344 km. 1 US gallon = 3.785411784 L. 1 imperial gallon = 4.54609 L. US MPG and imperial MPG use different gallon volumes. kW measures power; kWh measures energy.

Assumptions & limitations

  • Round trip doubles only distance and fuel. Enter tolls, parking and other expenses as totals covering all legs.
  • No toll, parking, fuel price, tax or exchange rate is supplied. Include charges in your inputs and avoid double counting. Vehicle wear, depreciation and lodging are excluded unless included in other expenses.
  • Uses a single average fuel efficiency and price for the entire journey. Real routes, traffic and fuel prices may vary.
