About AutoLog Pro: The Free Expense Tracker

Welcome to the most comprehensive free vehicle maintenance log available online. AutoLog Pro isn't just a spreadsheet; it's a financial tool designed to help car owners, tuners, and flippers understand the Total Cost of Ownership (TCO) and real-time resale value of their vehicles.

Key Features

  • VIN Decoder: Instantly fetch Year, Make, Model, and Trim data using the official NHTSA database.
  • Resale Value Algorithm: Unlike simple logs, we calculate depreciation based on mileage and adjust for positive modifications.
  • Multi-Currency Support: Track expenses in USD, EUR, GBP, JPY, CAD, AUD, and more.
  • Cost Per Mile (CPM): Know exactly what every mile costs you in maintenance and fuel.
  • Digital Service History: Create a bulletproof record of care to justify a higher asking price when selling.

How to Use This Tool Effectively

  1. Onboard your Vehicle: Use your VIN number. Select your local currency.
  2. Log "Purchase" Details: Be accurate with your Purchase Price and Purchase Mileage.
  3. Categorize Wisely:
    • Use Maintenance for oil changes (Neutral impact).
    • Use Repair for broken parts (Neutral/Negative impact).
    • Use Modification for upgrades (Positive impact).
