Overview
The Driving Cost Calculator computes total fuel expenses from distance, fuel economy, and fuel price. Use it to budget commuting, road trips, or business travel costs.
Formula
Fuel Cost = (Distance / Fuel Economy) x Fuel Price. Example: 200 km, 12 km/L, gasoline at 1,650 KRW/L → (200 / 12) x 1,650 ≈ 27,500 KRW.
How to Use
- 1Enter the driving distance in km.
