Fuel Cost Calculator

The fuel cost calculator takes three inputs — distance, fuel consumption (L/100km or MPG), and fuel price — and instantly shows how much your trip will cost. The formula is straightforward: (distance ÷ 100) × consumption × price per liter. Toggle round-trip to double the distance automatically, or switch between km/miles and liter/gallon units depending on your region.

Average car consumption ranges from 5-7 L/100km for city cars to 10-15 L/100km for trucks and SUVs. At highway speeds above 120 km/h, consumption typically jumps 20-30% compared to the optimal 80 km/h range. Air conditioning adds another 5-10% to fuel usage, while city stop-and-go driving can increase consumption by 30-50% compared to highway cruising.

Planning a road trip? Use the round-trip toggle to get accurate costs for your entire journey. For longer trips, consider that fuel prices vary between stations and regions — the calculator gives you a baseline to budget from. Combine this tool with our Unit Converter for distance conversions and Opportunity Cost Calculator to evaluate whether driving versus flying makes financial sense.
