You enter your car's average consumption (l/100 km), departure and destination city, and the calculator uses real prices from local gas stations (updated 16 septembrie 2026) to show the total trip cost and how many lei you save per month and per year by refueling smarter.

Calculation details
How much does my car use? (l/100 km)
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 1486 stations in Romania, updated 12 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: 9.97 RON/liter — see petrol price trends
- Standard diesel: 10.68 RON/liter — see diesel price trends
- Auto LPG: 4.70 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.
