Bike Mileage Calculator

Measure what your motorcycle or scooter actually returns, from one tank of fuel.

6 inputs Free, no sign-up

Your figures

Trip meter between the two fill-ups. Most bikes have one; if yours does not, use the odometer difference.

What it took to fill back to the same point. On a small tank, getting this to the same level both times matters more than it does on a car.

The price you actually paid. Pump prices move daily and differ by several rupees between states, so the round number here is a placeholder, not a quote.

About this calculator

A bike's advertised mileage and a bike's real mileage are rarely the same number. Measuring your own takes two fill-ups: fill the tank, reset the trip meter, ride as you normally do, fill it again, and divide.

Small tanks make this easier in one way and harder in another. A five-litre fill is a big share of the tank, so the measurement is over a meaningful amount of fuel — but a centimetre of difference in how full you stopped is a larger error than it would be on a car.

How to use this calculator

  1. Fill the tank to the brim, or to a mark you can repeat, and reset the trip meter.
  2. Ride normally until the tank is well down — a longer run gives a better figure.
  3. Fill to exactly the same point again and note the litres.
  4. Enter the distance and the fuel. Add the price for a cost per kilometre.

Use the same pump if you can. Pumps differ slightly in where they cut off.

The formula

Mileage     = Distance / Fuel used
Cost per km = Fuel price / Mileage

The result is shown in all four units. Indian bikes are quoted in km/L; a figure you see quoted in mpg on an international forum is almost always an imperial gallon, which is about 20% larger than a US one and therefore about 20% more flattering.

Worked example

250 km on 5 litres:

Mileage = 250 / 5 = 50 km/L

With petrol at ₹105, that is ₹2.10 a kilometre — roughly a third of what the same distance costs in a small car.

Notes and limits

  • Riding style moves a bike's mileage more than a car's. Hard acceleration on a small engine is a large fraction of its total output.
  • Tyre pressure and chain tension are the two maintenance items that show up in the figure fastest.
  • A pillion rider is a large percentage of a bike's total weight and the mileage reflects it.
  • The reserve tap or warning light is not a fixed number of litres on every bike. Do not treat "on reserve" as a known quantity.
  • For a scooter with a smaller tank, one tank is a short sample. Measure three.

What this calculation assumes

  • The tank was filled to the same point both times.
  • The figure is your measurement, not a rating for the model.

Frequently asked questions

How do I calculate my bike's mileage?

Fill the tank, reset the trip meter, ride normally, then fill again to the same point and note the litres. Divide the trip distance by the litres. At 250 km on 5 litres, that is 50 km/L.

Why is my mileage below the claimed figure?

Claimed figures come from a controlled test at a steady moderate speed with a light rider and no traffic. City riding with stops, a pillion and hard acceleration is a different thing, and 20-30% below the claim is ordinary.

Does tyre pressure really affect mileage?

Yes, measurably. Under-inflated tyres deform more and take more energy to roll. Checking pressure fortnightly is the cheapest thing you can do for both mileage and tyre life.
