Car Ownership Knowledge Base
Practical, no-jargon guides on the real cost of owning a vehicle. Every article is written in-house by the YNB Automotive editorial team and reviewed against the assumptions baked into our calculator, so the numbers you read here are the numbers the tool actually uses.
How to use these guides
If you are new to total-cost thinking, start with the True Cost to Own overview. It defines the five cost buckets every car owner faces — depreciation, interest, insurance, fuel, and taxes — and shows how small changes in each one can swing a five-year budget by thousands of dollars.
From there, pick the guide that matches your decision. Comparing an EV with a gas car? Read the EV vs. Gas guide. Trying to decide between a long auto loan and leasing? The Auto Loan Basics and Buying vs. Leasing guides work together. Each article includes a "Try this scenario" block so you can drop the numbers into our ownership cost calculator and see the result for your own inputs.
All examples are labeled with the inputs used. We do not claim national averages or "best" rankings unless we can link you to the primary source. For the full source list, see Data Sources & Resources.
