What is a Mileage?
A Mileage Calculator computes a vehicle's fuel efficiency from actual trip data — the distance covered and the fuel consumed — and translates that into three internationally recognised efficiency metrics (km/L, L/100km, and MPG), plus the total fuel cost and cost per kilometre for the journey. It turns raw fill-up receipts into actionable insights about your vehicle's real-world performance.
In India, fuel efficiency is expressed as km/L (kilometres per litre) and is the primary number consumers use to compare cars, track maintenance, and estimate running costs. The ARAI (Automotive Research Association of India) certifies mileage figures for all vehicles sold in India, but these figures are measured under controlled lab conditions and typically exceed real-world mileage by 15–25%. Using the Mileage Calculator on your own fill-up data gives you the accurate number specific to your driving pattern.
Tracking mileage over time is also an early warning system for vehicle health. A sudden 15–20% drop in fuel efficiency — without any change in driving habits — often signals engine issues, a clogged air filter, low tyre pressure, or a fuel system problem. Catching this early can prevent expensive repair bills. The Mileage Calculator makes it easy to compute your km/L at every fill-up and spot trends.
Mileage is directly tied to fuel cost, which for many Indian households is a significant monthly expense. At ₹105 per litre, driving 1,500 km per month at 12 km/L costs ₹13,125 in fuel — a figure the Mileage Calculator surfaces immediately alongside the efficiency metrics, helping you see the rupee impact of every km/L gained or lost.
How to use this Mileage calculator
- Enter Distance Travelled — the odometer reading change or trip meter distance in kilometres since the last full-tank fill-up.
- Enter Fuel Consumed — the number of litres added at the petrol pump to refill the tank to the same level. Use the full-tank method for accuracy: fill to full, drive, fill to full again, and note the litres added on the second fill.
- Enter Fuel Price — the current price per litre in ₹. Check your pump receipt for the exact figure, as prices change daily in India.
- Read the results — KMPL is the headline figure, with L/100km and MPG for international comparisons. The efficiency bar contextualises your result against Indian benchmarks. The cost panel shows the full trip cost and per-km cost.
Formula & Methodology
KMPL = Distance (km) ÷ Fuel Consumed (L) L/100km = 100 ÷ KMPL MPG (US) = KMPL × (1 km ÷ 1.60934 miles) ÷ (1 L ÷ 3.78541 US gallons) = KMPL × 2.35215 Total Fuel Cost = Fuel Consumed (L) × Fuel Price (₹/L) Cost per Kilometre = Total Fuel Cost ÷ Distance (km) Worked example: A Maruti Baleno owner in Pune drives from Pune to Goa and back — approximately 900 km round trip — and adds 62 litres of petrol at ₹103/L to refill the tank. - KMPL = 900 ÷ 62 = 14.52 km/L - L/100km = 100 ÷ 14.52 = 6.89 L/100km - MPG = 14.52 × 2.352 = 34.15 MPG - Total Fuel Cost = 62 × 103 = ₹6,386 - Cost per km = 6,386 ÷ 900 = ₹7.10/km The owner's real-world mileage of 14.52 km/L compares against the ARAI figure of 22.35 km/L — a 35% real-world reduction consistent with highway driving at 100+ km/h in terrain and with luggage weight.
