What does it actually cost to own a car per year?

For a typical midsize car, annual ownership costs run $6,200–$12,600 all-in when depreciation is included: depreciation $2,500–$5,000, insurance $1,200–$2,400, fuel $1,500–$2,500, maintenance and repairs $800–$2,000, and registration and fees $200–$700. Bureau of Labor Statistics data shows the average American household spends over $12,000 per year on a vehicle when all costs are counted. The monthly payment covers only a fraction of this.

What costs do people forget when buying a car?

Depreciation is the largest cost most people ignore entirely — every year the car exists, it loses value, and that wealth destruction is real even if no money changes hands. Other commonly overlooked costs: registration and property taxes (varies significantly by state), the interest portion of loan payments (a cost, not principal reduction), parking and tolls, and Day 1 acquisition costs on a purchase — sales tax, dealer fees, and the gap between trade-in value and private-sale value.

Why is the monthly payment a bad way to evaluate a car purchase?

The monthly payment buries total cost. A $350/month payment on a 72-month loan for a $22,000 car is $25,200 in total payments — $3,200 in interest to borrow money for a depreciating asset. Add depreciation, fuel, insurance, and maintenance over 6 years, and total ownership cost is likely over $50,000. Dealerships structure every conversation around the monthly payment because it keeps the total cost out of view. Calculate the out-the-door price, total interest paid, and full cost of ownership instead.

The True Cost of Owning a Car: What Nobody Tells You

Why Cars Cost More Than Anyone Tells You

When people talk about what their car costs, they usually mean the monthly payment. Sometimes they include gas. Occasionally they remember insurance. Almost nobody counts everything — and the costs they forget are substantial.

Bureau of Labor Statistics data consistently shows transportation is the second-largest household expense in the United States, behind housing. The average American household spends over $12,000 per year on a vehicle when all costs are counted. The monthly payment is what the dealership shows you. The rest of that $12,000 is what they don't.

The CrappyCar Witch was built specifically to count what gets left out. Not because the math is complicated — it isn't — but because the costs are scattered across time in a way that makes them easy to not see until you add them up.

My motivation: the dealership has a powerful incentive for you to think only about the monthly payment. Every other cost — depreciation, fuel, insurance, maintenance — is a fact that doesn't appear on their worksheet. That is not an accident.

Fixed Costs vs. Variable Costs

Car costs divide into two categories. Fixed costs happen whether you drive the car or not. Variable costs scale with use. Understanding which is which helps you compare options honestly.

Fixed costs (you pay these regardless)

Depreciation: the largest single cost for most car owners, and the most invisible. Every year the car exists, it loses value. That loss is real wealth destruction even if no money changes hands.
Insurance: required to drive legally, and priced by vehicle, driver profile, and coverage level. On a financed car, the lender typically requires comprehensive and collision coverage — which is more expensive than liability-only.
Registration and taxes: annual registration fees plus any property taxes on vehicle value — varies significantly by state
Loan interest: if you financed, the interest portion of each payment is a cost of ownership, not principal reduction

Variable costs (you pay more as you drive more)

Fuel: priced by MPG, local gas prices, and miles driven — meaningfully different between a 28 MPG sedan and a 20 MPG SUV at scale
Maintenance: oil changes, tires, brakes, filters, and scheduled services — increases with both age and mileage
Repairs: unplanned spending that scales with vehicle age, brand reliability, and how the car was previously maintained
Parking and tolls: real costs that vary by location, often invisible in ownership calculations

Knowing the categories is step one. Here's what they actually add up to.

What Cars Actually Cost: The Numbers

The American Automobile Association (AAA) and the Bureau of Labor Statistics both publish annual vehicle cost data. The picture they paint is consistent and sobering.

For a typical midsize car in the United States, annual ownership costs break down approximately as follows. These figures are averages and vary by vehicle, age, location, and driving habits — but the proportions are consistent.

Depreciation

$2,500–$5,000 per year depending on vehicle age and category. New vehicles lose more. The first 3 years are the most expensive period for depreciation. This is the cost most people forget entirely.

Insurance

$1,200–$2,400 per year for full coverage on a used vehicle, depending on location, driver profile, and vehicle value. Higher in urban areas. Required by lenders on financed vehicles.

Fuel

$1,500–$2,500 per year at average driving (12,000–15,000 miles) depending on fuel economy and local prices. A 6 MPG difference between two vehicles is $400–$600 per year at current prices.

Maintenance & Repairs

$800–$2,000 per year on a vehicle in good shape. Climbs with age and mileage. Brand matters significantly — RepairPal data shows average annual repair costs ranging from $300 for the most reliable brands to over $1,200 for the most expensive to maintain.

Registration & Fees

$200–$700 per year depending on state. Some states base registration on vehicle value (declining over time); others charge flat fees.

Add these together and the total annual cost of owning a used car — depreciation included — runs $6,200–$12,600 per year. If you financed the purchase, the interest portion of your loan payment is already captured above as a financing cost. The principal portion is equity accumulation, not a cost — it offsets the depreciation you're paying.

I run every one of these numbers: every projection in the analysis accounts for depreciation, fuel, estimated maintenance, insurance benchmarks, and acquisition costs. The Prophecy Matrix exists because the payment alone is not the picture.

The Monthly Payment Illusion

Dealerships discovered decades ago that buyers make decisions based on monthly payments, not total cost. The entire structure of a dealership sales conversation is built around this insight.

The four-square worksheet. The "what can you afford per month?" question. The financing office with its extended warranties that add "$40 a month." The offer to extend your loan term to bring the payment down. All of it is designed to keep your attention on one number while the total cost quietly climbs.

The Witch's antidote to anchoring bias

Calculate the out-the-door price, not the monthly payment — this is the real cost of acquisition
Calculate the total interest paid over the loan term: (monthly payment × months) − principal = total interest
Add the total interest to the purchase price — that is what the car actually costs you, before fuel, insurance, or maintenance
Compare two cars on total cost of ownership over a defined period — not on monthly payment — and the ranking often changes

A $350/month payment on a 72-month loan for a $22,000 car is $25,200 in total payments. The car cost $22,000. You paid $3,200 in interest to borrow money that bought a depreciating asset. Add annual depreciation, fuel, insurance, and maintenance over 6 years, and the total ownership cost is likely over $50,000.

Before you agree to any purchase, run this test: what will you spend on this car over the years you plan to own it — payments, interest, fuel, insurance, maintenance, minus what you'll recover when you sell? That number is your actual decision. The monthly payment is not — and neither is the number on the window sticker. Don't let them steer you away from it.
