**How to calculate fuel cost?**

Here are the steps to calculate the fuel cost for a day, month or year:

- Find out the cost of petrol, diesel or CNG fuel per unit in your city or locality. For the liquid fuels like petrol and diesel, you’ll need the cost of fuel per litre as it retails in volume. For CNG, which sells by weight, you’ll need the cost per kilogram.
- Second, you need the mileage or km you are expecting the car to deliver from one unit of fuel. For petrol or diesel cars, this value will come in kmpl (kilometres per litre of petrol/diesel) and for CNG vehicles, this value will be in kmpkg (kilometres per kilogram of CNG).
- Once you have the petrol, diesel or cng gas mileage and fuel cost, divide the fuel cost by mileage to get the cost of fuel per kilometer.
- Finally, multiply the cost per kilometer by the number of kilometres you intend to travel daily, monthly or in a year. This will give you the final cost you might incur for your daily, monthly or a year worth of travel with petrol, diesel or CNG car.
