Once you have km/L (or km/kWh), use the Fuel Cost Calculator: cost ≈ distance ÷ mileage × price.

How to calculate petrol cost using mileage?

Petrol cost = distance ÷ km/L × petrol ₹/L.

Fuel = 500 ÷ your calculated mileage.

After mileage is known, cost/km ≈ fuel price ÷ mileage.

Check tyre pressure, service on time, reduce idling, and avoid aggressive acceleration — then re-measure mileage here.

Find your real-world mileage (km/L, km/kg or km/kWh) from distance driven and fuel used.
