How to Calculate the Mileage of a Car?

If you’ve ever wanted to know how far your car can travel on a litre of fuel, you can easily figure it out by following these simple steps. Keeping track of this helps you understand how efficiently your car uses fuel. Knowing how to calculate the mileage of a car allows you to make smart decisions about when to refuel, plan your trips more effectively, and save money on fuel. Also having car insurance is also necessary. Let’s go through the easy steps to find out your car’s mileage, understand the mileage calculation and know why you should have car insurance. 

Mileage calculation of your car is a handy skill that can help you understand how efficiently your vehicle uses fuel. Follow these steps to accurately calculate the mileage of your car:

Fill Up the Fuel Tank:

Start by completely filling your car’s fuel tank and make a note of the quantity added in litres. This step is crucial for obtaining precise fuel consumption and mileage measurements.

Check the Odometer Reading:

Take note of the current reading on your car’s odometer before starting your drive. After covering a certain distance, check the new reading on the odometer. Calculate the distance travelled by subtracting the initial mileage from the latest reading. To find your car’s mileage, divide this distance by the amount of fuel used.

Drive Normally:

For accurate results, drive as you normally would without significantly changing your driving habits. Maintaining a consistent driving style and avoiding unnecessary detours ensures a more reliable calculation of your car’s average fuel efficiency.

Refuel Your Car:

After a period of driving, refuel your car and track the distance covered before refuelling again. Divide this distance by the amount of fuel added to determine your car’s mileage. Regularly refuelling and recording these numbers over time helps calculate the average mileage, providing insights into your vehicle’s fuel usage efficiency.

Do the Math:

Calculate the car’s mileage by determining the average distance it can travel per unit of fuel consumed. This computation helps evaluate the fuel efficiency of your car, empowering you to make informed decisions about fuel consumption and trip planning.

Check Periodically:

Keep a record of your car’s mileage regularly to track the distance it has travelled. Periodically note down the odometer reading and the amount of fuel added to calculate the mileage over specific periods. This practice allows you to monitor changes in fuel efficiency and identify potential issues with your car’s performance.

By following these steps and consistently monitoring your car’s mileage, you can better understand its fuel efficiency, make informed decisions about refuelling, plan your trips effectively, and identify any changes in performance over time.


If you want to figure out how much distance your car can travel on a litre of fuel, you can use a simple formula:

Car Mileage = (Second Odometer Reading – First Odometer Reading) / Number of Liters of Fuel

For example, let’s say you start a road trip with your car. Before you begin, note down the initial odometer reading, which is 20,000 kilometres, and fill up the fuel tank with 40 litres of fuel. After completing your journey, check the new odometer reading, which is now 21,000 kilometres.

Now, apply the formula:

Car Mileage = (21,000 km – 20,000 km) / 40

In this case, your car’s mileage would be 25 kilometres per litre of fuel. This tells you how far your car can go on each litre of fuel you use.

Why should you have a car insurance?

Legal Requirement:

According to the Motor Vehicles Act of 1988, it is mandatory for every car on Indian roads to have valid vehicle insurance continuously. Failure to comply may result in penalties, and repeated violations could lead to temporary or permanent cancellation of your driving license.

Protection for You and Your Vehicle:

Comprehensive car insurance covers not only third-party injuries or damages but also your own. It provides financial protection in cases of accidents as well as damages due to natural calamities, fire, theft, riots, terrorism, and more.

Choosing the Right Car Insurance:

Understanding the importance of motor insurance, it’s crucial to explore options online. Car insurance online helps to compare plans from reputable insurance providers, considering factors like their reputation, claim process, features, benefits, and policy premiums. Decide whether you need basic third-party coverage or comprehensive insurance to make an informed decision that suits your needs.


In conclusion, accurately calculating your car’s mileage involves simple steps like filling up the fuel tank and monitoring regularly. Understanding the average distance your car can travel on each unit of fuel empowers you to make informed decisions.

Additionally, recognising the importance of car insurance is crucial. Investing in comprehensive motor insurance serves as a vital safeguard, offering financial security in unforeseen road incidents. Both understanding your car’s mileage and having comprehensive insurance contribute to smarter and safer choices on the road.
