# I’m not sure about how to calculate the mileage using the odometer reading. How do I do it?

![Create credit note](/invoice/kb/images/invoice-dashboard.png) ![](/invoice/kb/images/expenses/mileage-using-odometer.gif)

It’s really simple. All you have to do is enter the **Start reading** displayed on the odometer before beginning the trip and enter the **End reading** displayed on the odometer once you complete the trip.

Fill in the other fields and click **Save** to finish.
