Enter the kilometers driven since your last full tank and the liters refueled — get your car's real consumption and what 100 km costs at today's price.
How the fuel cost calculator works
The PretCarburant.ro fuel cost calculator estimates the real cost of a trip between two cities in 2 seconds, using real prices from gas stations in the departure city. Unlike other calculators, it uses live data collected from 1370 stations in Romania, updated several times a day.
- Choose departure and destination city — distance is estimated automatically.
- Enter your average consumption — if you don't know it, calculate it with the "How much does my car use?" module from kilometers driven and liters refueled.
- Select the fuel type: petrol 95, diesel or LPG.
- See the compared result: minimum and maximum price on the route, total cost and savings if you refuel at the cheapest station.
Consumption formula: consumption (l/100 km) = liters refueled × 100 ÷ kilometers driven. Example: 35 liters over 500 km means 7 l/100 km.
Today's fuel prices used by the calculator
- Standard petrol 95: 10.02 RON/liter — see petrol price trends
- Standard diesel: 10.95 RON/liter — see diesel price trends
- Auto LPG: 4.71 RON/liter — see LPG price trends
The price difference between the cheapest and most expensive liter of fuel in the same city may seem small (20-40 bani), but on a long trip of 300+ km, the savings reach 10-20 lei per trip. Multiplied by the number of trips per month, the annual savings can exceed 500 lei.
