Annual Car Cost Calculator
Calculate the true total annual cost of owning your car.
Include fuel, insurance, maintenance, loan payments, and registration for a complete picture.
Total annual car cost is the sum of every recurring expense tied to owning and operating a vehicle. Most drivers significantly underestimate this figure because they only think about the monthly loan payment, not the full picture.
The master formula:
Annual Cost = Fuel + Insurance + Maintenance + (Loan Payment × 12) + Registration + Depreciation + Other
Cost per Mile = Annual Cost ÷ Annual Miles Driven
Cost per Month = Annual Cost ÷ 12
Variable definitions:
- Fuel: annual gasoline or electricity cost
- Insurance: full coverage premium per year
- Maintenance: oil changes, tires, brakes, fluids, unexpected repairs
- Loan Payment: monthly payment × 12 (or $0 if paid off)
- Registration: annual DMV fees and state taxes
- Depreciation: the loss in resale value each year (often the largest hidden cost)
Worked example:
A 2022 Honda CR-V with a $450/month loan payment, driven 15,000 miles a year:
- Fuel: $2,400/year (15,000 miles at $0.16/mile)
- Insurance: $1,800/year
- Maintenance: $900/year
- Loan: $450 × 12 = $5,400
- Registration: $250
- What the calculator returns: $10,750/year → $896/month → $0.72/mile
- Depreciation, which you add yourself: $3,200 (approx. 15% of $21,000 value)
- Full cost with depreciation: $13,950/year → $1,163/month → $0.93/mile
The calculator stops at the cash items because depreciation depends on what the car will sell for, and only you can guess that.
Average US annual costs by vehicle segment (2024–2025):
| Segment | Annual Cost |
|---|---|
| Small sedan | $8,500–$10,500 |
| Midsize SUV | $11,000–$14,000 |
| Full-size truck | $13,000–$17,000 |
| Electric vehicle | $9,000–$12,000 |
Top cost-reduction strategies:
- Fuel: Maintain proper tire pressure (saves ~3%), avoid aggressive acceleration
- Insurance: Compare quotes annually, raise deductible, bundle home + auto
- Maintenance: Follow the manufacturer schedule, not the dealer upsell
- Depreciation: Buy a vehicle that is 2–3 years old to skip the steepest depreciation curve
- Loan interest: Extra principal payments reduce total interest paid significantly
The cost-per-mile figure is especially useful for comparing owned vehicles against rideshare or rental alternatives.
