Introduction
Estimate trip fuel cost from distance, vehicle efficiency, and local fuel price — useful for road trips and commute budgeting.
Formula
Fuel cost is distance divided by efficiency (km per litre), times price per litre. L/100km mode uses (d/100)×rate.
- d — Trip distance (km)
- e — Efficiency (km/L) or L/100km rate
- p — Price per litre
- C — Total fuel cost
Step-by-step
- Enter distance and choose km or miles.
- Enter efficiency (km/L, mpg, or L/100km).
- Enter price per litre and review total cost.
Worked example
250 km at 18 km/L needs about 13.89 L. At ₹100/L the trip costs about ₹1,389.
Use cases
- Budget a road trip before booking hotels
- Compare petrol vs diesel running cost
- Estimate weekly commute fuel spend
