Calculate your Past Odometer Readings
If the IRS audits you for mileage, you’ll have to know your past odometer readings for the IRS to accept your mileage log.
To create a retrospective mileage log, use the odometer reading calculator to calculate how much the odometer reading could be 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. Without accurate odometer readings, your mileage logs will be inaccurate, so we recommend that you take the time to gather the data as soon as possible.
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). Check your VIN for more info.

10 and 20-year Rules for Odometer Disclosures
As of January 2021, for vehicles beginning with the Model Year 2011 odometer disclosures are required for every transfer of ownership for the first 20 years. The model Year 2010 and older vehicles are exempt from this rule, continuing to be subject to the previous 10-year odometer disclosure rule.
Fuel Mileage Calculator
Fuel economy in automobiles can be calculated in either US or metric units by using a Gas Mileage Calculator. Calculate your vehicle’s fuel efficiency in mpg-US (miles per gallon), mpg Imp (miles per Imperial gallon), km/l (kilometers per liter), or l/100km (liters per 100 kilometers).
Fuel economy/efficiency ratings are converted and displayed for all units, including mpg US, mpg Imp, km/l, and l/100km.
TIP: Do you have to change from a decimal odometer to a binary odometer or vice versa? Set a value and see the binary, octal, decimal, hexadecimal, and custom base versions of your odometer reading.
Odometer Reading Guide: How to Read an Old Odometer (Step-by-Step)
- Find the dashboard odometer: The speedometer panel has a rectangle-shaped glass.
- Check the arrangement: To calculate your distance, count the odometer digits. Some versions also show a tenth of a distance unit. This normally appears in a different-colored wheel.
- Read the displayed number from left to right.
- Add the current number to the rollover: Old odometers roll back to zero after a certain limit, reducing their accuracy. Note and add these readings to gain a better idea of the vehicle’s trip distance.
- How does an odometer work? How to read a transmission-shaft-connected gear-driven wheel drives odometers? As the shaft rotates at the same pace as the wheels, the mechanism can estimate your car’s distance by multiplying the number of spins by the tire’s circumference.
Odometer calculator by brand and Model
You can find an odometer calculator with a thorough breakdown of vehicle categories, brands, models, and even memory types, where you can easily find your own vehicle to calculate the odometer for distances traveled. You can even upload your own dashboard file.
How Can a Tire Size Calculator help?
The tire size calculator compares the diameter, breadth, sidewall, circumference, and rotations per mile of two tires. Then, as an added benefit, it displays samples of your speedometer reading with the first tire and the real speed you’re moving if the second tire is installed. When looking for tires that are a different size than standard, this tire calculator comes in handy.
Using MileageWise to create a mileage log, you’ll be able to reconstruct your past mileage. With the help of our AI-based AI Wizard feature that fills the gaps in your incomplete logs, you can create a backtracked, IRS-compliant mileage log.

FAQs about Mileage Tracking for Taxes
Is it better to track mileage or gas on taxes?
Tracking mileage is often better because the IRS standard mileage rate typically covers gas, maintenance, and other vehicle expenses, making it simpler.
Can I switch from actual to standard mileage?
If you opt for the standard mileage rate during the first year a vehicle is in use, you have the option to alternate between using the standard mileage and actual expenses methods each year. However, if you start with the actual expenses method in the first year, you must continue using this method for as long as you use that vehicle for business.
What counts as mileage for taxes?
Mileage for business, medical, moving (if eligible), and charitable purposes counts, but commuting to and from work generally does not.
What is considered medical mileage?
Medical mileage refers to the distance traveled for medical care which can be deductible from taxes if it meets certain IRS criteria.
How do I track mileage for taxes?
Use a mileage tracking app, a mileage logbook, or a spreadsheet to record the date, purpose, start/stop locations, and miles driven.
Why is the Odometer Reading Important?
Determining Car Value
The mileage recorded by your odometer is a significant factor in determining your car’s resale value. Generally, the more miles a car has traveled, the lower its resale value will be. Buyers often associate high mileage with more wear and tear, leading to potential future repairs.
Legal Responsibilities
When selling a vehicle, it’s legally required to disclose the accurate mileage. Any discrepancies between the actual mileage and the number displayed on the odometer can even lead to accusations of fraud.
Car Insurance
Your odometer reading can affect your car insurance premiums. Some insurance companies offer discounts for low-mileage vehicles since they are statistically less likely to be involved in accidents.
Fuel Efficiency Monitoring
Monitoring your car’s fuel efficiency is easier when you keep track of your odometer readings. By noting the mileage at each fill-up, you can calculate how many miles you’re getting per gallon. Furthermore, this also helps you spot any issues with your car’s engine or fuel system early on, if you have unusullay large fuel consumption.
Mileage Deduction for Taxes
If you use your car for business or are self-employed, keeping precise records of your mileage is vital for claiming deductions. However, documenting only your odometer readings is not adequate for mileage deduction
Tip: Consider using a mileage tracking app to record your miles consistently. These tools help ensure you’re not leaving money on the table when it’s time to file your taxes.
Manually keeping a mileage log isn’t just time-consuming; it also leaves you prone to around 70 potential logical errors when using Excel-based mileage log templates—errors you can avoid entirely by using our MileageWise dashboard
