1. What is Annual Miles Calculation?

The Annual Miles calculation determines how many miles a vehicle has been driven over the course of one year by comparing the current odometer reading with the reading from one year ago.

2. How Does the Calculator Work?

The calculator uses a simple formula:

Where:

• Odometer Current — Current mileage reading (miles)
• Odometer Last Year — Mileage reading from one year ago (miles)

Explanation: The calculation simply subtracts last year's odometer reading from the current reading to determine miles driven in the past year.

3. Importance of Tracking Annual Miles

Details: Tracking annual miles helps with vehicle maintenance scheduling, insurance calculations, fuel efficiency monitoring, and determining vehicle depreciation.

4. Using the Calculator

Tips: Enter both odometer readings in miles. The current reading should be equal to or greater than last year's reading. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What if my odometer rolled over?
A: For vehicles that have exceeded their odometer capacity, you'll need to account for the rollover by adding the maximum odometer value to your calculation.

Q2: How accurate is this calculation?
A: The calculation is mathematically precise, but accuracy depends on having correct odometer readings from both time periods.

Q3: Can I use kilometers instead of miles?
A: Yes, but be consistent - use kilometers for both inputs and interpret the result as kilometers.

Q4: Why track annual miles?
A: Helps determine if you're driving more or less than average (12,000-15,000 miles/year is typical in the US), which affects maintenance needs and resale value.

Q5: What if I don't have last year's odometer reading?
A: You can estimate based on service records or divide total miles by vehicle age, but this will be less accurate.
