For each vehicle: distance in km ÷ mileage (km per litre) × fuel price per litre. With multiple vehicles the costs are summed, assuming every car drives the full distance.

It is the combined amount your group spends per day on food, stays and everything that is not fuel. If you know the per-person figure, multiply it by the number of travellers first.

No — it only changes the symbol shown next to the numbers. Your amounts are never converted, so enter costs in whichever currency you plan to spend.

Estimate total trip cost as: fuel cost + daily expenses × days + tolls/parking. Fuel cost = (total distance ÷ vehicle mileage) × fuel price per litre/gallon. With multiple cars, compute fuel per vehicle and sum them, then split the total across travellers.

Diesel needed = 200 ÷ (vehicle mileage in km/l). Example: if your mileage is 12 km/l, diesel = 200 ÷ 12 ≈ 16.67 litres.

Trip time ≈ total distance ÷ average speed. Convert units consistently (e.g., kilometres and km/h). Add buffer for stops/traffic if needed.

Toll charges are the sum of tolls for the route segments you travel. If you have a list of toll points, add each toll amount. If you only know total toll spend, use that value directly.

A road trip cost calculator estimates your fuel, daily expenses, and tolls/parking, then divides the total across travellers. The result updates instantly as you change distance, days, travellers, daily spending, and fuel prices.

Gas (fuel) used = total distance ÷ vehicle mileage. For example, fuel litres = distance ÷ (km per litre). If your calculator also supports round trips, multiply the one-way distance by 2 first.

Use the same rule: fuel used = trip distance ÷ mileage. Enter the distance you’ll actually drive (one-way or round trip) and your fuel economy, then the calculator converts that into fuel quantity.

Trip gas cost = fuel quantity × fuel price. If your calculator supports multiple vehicles, compute fuel cost per vehicle using each vehicle’s mileage and fuel price, then sum them for the trip total.
