LOCALDriving-trip budget
Estimate fuel from distance, economy and price
Start with one-way distance
Enter the one-way distance and choose whether to include the return trip. Do not enter a return-trip total and also enable Round trip.
Use your car’s economy and fuel price
Enter km/L and the price per litre in KRW. Recent driving records can make a more useful planning assumption than a specification alone.
Read the total and split
Review fuel needed, total cost and cost per kilometre. Set the number of people sharing to see an equal per-person split.
A worked example
Four people on a 200 km return journey
- Start with
- 200 km one way / round trip / 12 km/L / 1,650 KRW/L / four people
- Check the result
- 400 km, about 33.33 L, 55,000 KRW total and 13,750 KRW each
Calculated as 400 ÷ 12 × 1,650. Add tolls and parking separately.
