    Fourteen cost categories, one annual total

    Most car owners track fuel and insurance but overlook depreciation, tire wear, parking and tolls. This calculator collects every recurring expense - fuel or electricity, liability and comprehensive insurance, service, inspections, tires, parking, car washes, highway tolls, loan payments and depreciation - then returns a single annual figure, a monthly budget and a cost-per-kilometer breakdown. A 5-year TCO projection shows the true long-term price of owning your vehicle.

    Cost atlas - six expense categories

    Fuel / Energy
    Gasoline, diesel, LPG or electricity. Typically $1,200-3,500/year at 20,000 km. Usually the largest single category for combustion cars.
    Insurance
    Liability plus optional comprehensive/collision. Range: $800-4,000/year. Young drivers and sports cars pay significantly more.
    Service and Tires
    Oil, brakes, filters, inspections and tire amortization. Typically $600-2,500/year. EVs cost 40-60% less in this category.
    Parking and Tolls
    Monthly parking, garage fees and highway tolls. Urban drivers: $1,200-5,000/year. Suburban with free parking: near $0.
    Loan / Lease
    Monthly payment times 12. Typical range: $3,600-8,400/year. Paid-off car: $0. This is a cash outflow, not a pure ownership cost.
    Depreciation
    Hidden value loss. New car year 1: 15-25%. A $30,000 car loses $3,000-7,500 in the first year alone. Often the biggest cost of all.

    Annual cost classification

    Total annual cost Classification Typical profile
    Under $3,000 Economical Paid-off compact, low mileage, basic insurance
    $3,000 - $6,000 Average Mid-size sedan, 15,000-20,000 km/year, no loan
    $6,000 - $10,000 Premium SUV or newer car with loan, higher mileage, full insurance
    Over $10,000 Luxury Premium brand, high depreciation, urban parking, active loan

    How to use - step by step

    1. Drivetrain type - select gasoline, diesel, LPG, EV or PHEV. This changes units and hints for the fuel fields.
    2. Fuel consumption and price - enter average l/100 km (or kWh/100 km for EV) and cost per liter (or per kWh).
    3. Annual mileage - total km driven per year. The US average is about 20,000-24,000 km.
    4. PHEV section - appears only for plug-in hybrids. Enter the percentage driven on electricity, kWh/100 km and electricity price.
    5. Insurance - enter liability (required) and comprehensive/collision (optional) annual premiums.
    6. Service - inspection fee, annual service/repair cost and tire amortization per year.
    7. Other costs - monthly parking, car wash, annual tolls and monthly loan/lease payment.
    8. Depreciation - optional. Enter current car value and annual depreciation rate to see the full TCO.
    9. Read the result - total annual cost, monthly budget, cost per km, category breakdown and 5-year projection.

    EV (Tesla Model 3, with loan) 18,000 km $400 $2,200 $400 ~$9,000
    Diesel pickup (high mileage) 35,000 km $3,500 $2,000 $1,800 ~$8,500
    Luxury sedan (BMW/Audi, leased) 20,000 km $2,200 $3,500 $2,000 ~$15,500

    FAQ - Frequently asked questions

    What is the biggest hidden cost of car ownership?
    Depreciation. A new $35,000 car can lose $5,000-8,000 in the first year alone (15-25% of its value). After 5 years, a typical car is worth only 40-50% of its original price. Buying a 2-3 year old car avoids the steepest depreciation curve and can save $10,000+ over 5 years.
    Is an electric car really cheaper to run?
    In running costs, yes. Electricity at home charging costs roughly $0.04-0.06 per km versus $0.08-0.15 per km for gasoline. EVs also have lower service costs (no oil changes, less brake wear due to regenerative braking). However, the higher purchase price and faster depreciation on some EV models can offset these savings over 5 years.
    How much does insurance cost on average?
    The US average for full coverage is about $1,600-2,200/year. Liability-only averages $600-900/year. Factors that raise premiums: age under 25, sports cars, urban areas, poor driving record. Shopping around between 3-5 insurers can save 20-40% on the same coverage.
    Should I include the loan payment in total cost?
    It depends on what you want to measure. The loan payment is a cash outflow that affects your monthly budget. However, in a strict TCO (total cost of ownership) analysis, the purchase price is captured through depreciation, not the loan. This calculator shows both: operating costs without the loan, and full cost with it, so you can see both perspectives.
    How can I reduce my annual car cost?
    The biggest levers: (1) Drive less - each 1,000 km saved cuts $50-150/year in fuel alone. (2) Compare insurance - quotes vary by 30-50% for identical coverage. (3) Buy used - a 3-year-old car costs 30-40% less and has similar reliability. (4) Consider LPG conversion - saves 40-50% on fuel at the cost of $1,000-2,000 upfront. (5) Do basic maintenance yourself - oil, filters and brake pads are straightforward.
    What does the 5-year projection include?
    The projection multiplies annual operating costs by 5 and calculates compound depreciation (each year applies the percentage to the remaining value, not the original). For example, a $30,000 car losing 10% per year is worth ~$19,700 after 5 years (not $15,000). If a loan is included, the total cash outflow is shown separately since loan payments end but depreciation continues.
