Total Cost of Car Ownership Calculator

Enter your vehicle purchase price, annual depreciation rate, ownership period, annual mileage, fuel economy, gas price, and yearly insurance, maintenance, registration, and loan interest to see your true Total Cost of Ownership.

About this calculator

Combine compound depreciation, fuel, auto insurance, maintenance, registration fees, and loan interest into one multi-year Total Cost of Ownership (TCO).

Core Mathematical Formula

Depreciation = Purchase Price − [Purchase Price × (1 − DepRate ÷ 100)^Years]
Fuel Cost = (Annual Distance ÷ MPG) × Fuel Price × Years
Total TCO = Depreciation + Fuel + (Insurance + Maintenance + Registration) × Years + Loan Interest

Verified Calculation Benchmark

A $28,000 car held for 5 years (15%/yr depreciation = $15,576.25 loss), driven 12,000 miles/year at 28 MPG with $3.50/gal gas ($7,500.00 fuel), $1,200/yr insurance ($6,000.00), $600/yr maintenance ($3,000.00), $180/yr registration ($900.00), and $2,400.00 loan interest has a 5-year TCO of $35,376.25 ($7,075.25/year).

Why Sticker Price Is Only Half the Story: Understanding Total Cost of Ownership (TCO)

Your monthly loan payment is barely half of what a vehicle actually costs you over five years. In our own five-year audits of family crossovers and pickups, combining compound wholesale depreciation, fuel, full-coverage insurance, maintenance, taxes, and loan interest reveals the true wealth impact of any car purchase. Ground your inputs using EPA FuelEconomy.gov energy data, Bureau of Labor Statistics (BLS) household transportation benchmarks, and Consumer Financial Protection Bureau (CFPB) financing guidelines.

Two vehicles can sit side by side on a dealership lot with the exact same $34,000 window sticker, yet cost $14,000 apart over a five-year ownership cycle. One might be a high-residual hybrid crossover averaging 40 MPG with modest insurance premiums and a 10.5% annual depreciation rate; the other might be a three-year-old off-lease European luxury turbo sedan requiring 93-octane premium fuel, $2,400/year in collision coverage, and $1,600/year in out-of-warranty suspension and cooling-system maintenance.

Corporate fleet managers never evaluate vehicles by sticker price, they evaluate Total Cost of Ownership (TCO) across six distinct cost buckets: net depreciation, cumulative fuel energy, auto insurance premiums, scheduled and unscheduled maintenance, annual state registration/property taxes, and total financing interest. The Khulasa Total Cost of Car Ownership Calculator puts that same six-bucket institutional framework into a single transparent model.

Step-by-Step 5-Year TCO Calculation (Verified Walkthrough)

Suppose you purchase a $28,000 compact SUV, hold it for 5 years, drive 12,000 miles per year at 28 MPG with fuel at $3.50/gallon, and assume a 15% annual depreciation rate, $1,200/year insurance, $600/year maintenance, $180/year registration, and $2,400 in total 5-year loan interest:

  1. 5-Year Compound Depreciation:
    Final Value = $28,000 × (1 − 0.15)^5 = $28,000 × 0.443705 = $12,423.75
    Total Depreciation = $28,000.00 − $12,423.75 = $15,576.25 (44.0% of total 5-year TCO)
  2. 5-Year Fuel Expenditure:
    (12,000 miles ÷ 28 MPG) × $3.50/gal × 5 years = 428.5714 gal/yr × $3.50 × 5 = $7,500.00 (21.2% of TCO)
  3. 5-Year Auto Insurance:
    $1,200/yr × 5 years = $6,000.00 (17.0% of TCO)
  4. 5-Year Maintenance & Tires:
    $600/yr × 5 years = $3,000.00 (8.5% of TCO)
  5. 5-Year Registration & Renewal Taxes:
    $180/yr × 5 years = $900.00 (2.5% of TCO)
  6. Total Financing Interest:
    $2,400.00 (6.8% of TCO: you can calculate your exact loan interest using our Car Loan Calculator)
  7. Grand Total 5-Year TCO:
    $15,576.25 + $7,500.00 + $6,000.00 + $3,000.00 + $900.00 + $2,400.00 = $35,376.25
    Annualized Ownership Cost: $35,376.25 ÷ 5 years = $7,075.25 per year ($589.60 per month, or $0.5896 per mile across 60,000 miles).

Why Keeping a Reliable Car for 8–10 Years Is the Ultimate Wealth Builder

Run the calculator above for 5 years, and then re-run it for 10 years on the same vehicle. Even if your annual maintenance budget doubles from $600/year in Years 1–5 to $1,400/year in Years 6–10, your annualized cost of ownership drops dramatically in the second five years because loan interest drops to $0 and annual dollar depreciation drops by more than half. Read our detailed breakdown of the true 5-year cost of a $35,000 crossover to see how every expense line evolves year by year.

Frequently Asked Questions

Why isn't my monthly loan principal payment added on top of depreciation in TCO?

Adding both full loan principal payments and depreciation would double-count the vehicle's purchase price. In TCO accounting, your capital loss on the vehicle itself is measured by Depreciation (Purchase Price minus Resale Value), while the cost of borrowing money is captured separately by Total Loan Interest.

What is the biggest hidden cost of owning a new car?

Depreciation is almost always the largest single cost of owning a new car, accounting for roughly 40% of total 5-year ownership expenses, ahead of fuel, insurance, and financing interest.

How do I find my total loan interest to enter into the TCO calculator?

Open the Khulasa Car Loan Calculator, enter your vehicle price, down payment, APR, and loan term, and copy the Total interest result directly into the Total loan interest field here.

Why do some states have much higher annual registration costs in TCO?

States like Virginia, Massachusetts, Connecticut, Missouri, and California assess annual ad-valorem vehicle property taxes or Value-Based License Fees (VLF) of 1% to 4%+ of assessed value every year, whereas states like Texas and Florida charge flat renewal fees ($50–$85/year).

Is a 3-year-old used car always cheaper in TCO than a new car?

Usually yes, buying a 3-year-old vehicle skips the steepest 35%–40% portion of the depreciation curve. However, if used car APRs are 4% higher than manufacturer promotional new-car APRs and the car needs tires and 60,000-mile fluid services immediately, a high-residual new car (like a Civic or RAV4) can come surprisingly close.
