⛽ Fuel & Trip Cost Calculator
Estimate what a journey costs in fuel — works with miles or km, US/UK mpg or L/100km, and per-gallon or per-litre prices.
About this calculator
Enter how far you're driving, your car's fuel economy and the price of fuel, and this works out the fuel needed, total cost, and cost per mile/km. It mixes unit systems freely, so you can use US gallons with miles, or litres with kilometres, or anything in between — handy for road-trip budgeting and comparing cars. You can also split the cost between passengers.
