Why Total Cost of Ownership Matters

The sticker price or monthly payment is only part of what a car really costs. Insurance, fuel, and maintenance add up fast, and this calculator combines them all into one clear monthly, annual, and per-mile figure.

Formula

Total Annual Cost = (Payment + Insurance + Fuel + Maintenance) × 12

Cost per Mile = Total Annual Cost ÷ Annual Miles Driven

How to Use This Calculator

Example

A car costing $730/month in total, driven 12,000 miles/year, costs about $0.73 per mile to own and operate.

Frequently Asked Questions

What is Total Cost of Ownership (TCO) for a car?

It's the full cost of owning a vehicle over time, including purchase/loan payments, depreciation, insurance, fuel, maintenance, and repairs — not just the sticker price.

Why is TCO more useful than purchase price alone?

Two cars with similar prices can have very different total costs due to differences in fuel efficiency, reliability, insurance rates, and depreciation.

What's usually the biggest hidden cost in car ownership?

Depreciation is often the largest single cost over a few years of ownership, frequently exceeding fuel or maintenance costs combined.
