Hi melissanne
Thanks for joining us here on the Community,
To do this, please go to 'Mileage' from the left menu and then change the drop-down from 'Fiscal Year' to 'Custom Date' and enter the desired start and end dates.
The total 'Business Distance' will then update below, as well as the 'Total Distance' (a total of the business and personal miles). Deduct the business distance from the total distance to get your total personal miles.
Please get back to us below if you have any questions, or if you have any feedback relating to this, you can submit this by going to the Cogwheel > Feedback within your account. :)
