Calculate your past odometer readings
If the IRS audits you for mileage or for any other reason you have to know your past odometer readings.
To create a retrospective mileage log, use the odometer reading calculator to calculate how much the odometer reading could have been at certain refuelings / chargings and at the end of the month!
Before you get started, you’ll need some information:
- the starting odometer reading of your vehicle,
- the current odometer reading of your vehicle,
- approximate fuel consumption of your vehicle,
- the date of your refuelings / chargings,
- amount of fuel refueled per refueling / charging.
Without this information, you will not be able to calculate accurate odometer readings at certain refuelings / chargings with or without our calculator. And without accurate odometer readings, your mileage logs will be inaccurate, so we recommend that you take the time to gather the data!
Tip: You can find information about the odometer readings recorded during a service visit or vehicle inspection by checking your vehicle’s history if you know its VIN (Vehicle Identification Number) here.
