Projekt-Plan
Why: You need the exact purchase price and loan terms to calculate depreciation and interest costs accurately.
How:
- Locate your sales contract or bill of sale.
- Identify the total purchase price (including taxes and fees).
- Note down your monthly loan payment and the interest rate (APR).
Done when: You have the original purchase price and financing details ready.
Why: Most variable costs (fuel, maintenance, tires) are directly tied to how much you drive.
How:
- Check your odometer for the current total mileage.
- Estimate your annual mileage by looking at service records from the last 12 months.
- If unknown, use the 2025 average of 13,500–15,000 miles per year as a benchmark.
Done when: You have a realistic estimate of your annual mileage.
Why: These are fixed annual costs that often increase due to inflation and regional risk adjustments.
How:
- Log into your insurance portal to find your annual premium (2025 average is ~$2,150 for full coverage).
- Find your latest vehicle registration or property tax bill.
- Sum these up to get your annual fixed regulatory cost.
Done when: You have a total figure for annual insurance and taxes.
Why: Depreciation is the largest single expense, averaging $4,334/year in 2025, yet it's often ignored.
How:
- Find your car's current market value using a generic valuation tool (e.g., KBB or Edmunds).
- Formula: (Original Price - Current Value) / Years Owned.
- For new cars, expect 20% loss in year one and 15% annually thereafter.
Done when: You have a specific annual dollar amount for value loss.
Why: Only the interest portion of your loan is a 'cost'; the principal is technically equity (though in a depreciating asset).
How:
- Review your loan amortization schedule.
- Sum the interest paid over the last 12 months.
- If you paid cash, this value is $0 (but will be captured in Opportunity Cost).
Done when: You know exactly how much you pay in interest per year.
Why: The money tied up in your car could be earning returns elsewhere (e.g., in an S&P 500 index fund).
How:
- Take the current market value of your car.
- Multiply it by a conservative expected return (e.g., 5% or 7%).
- Example: A $30,000 car has an opportunity cost of $1,500/year at 5%.
Done when: You have calculated the 'lost' investment income.
Why: Fuel is the most visible variable cost, averaging 13 cents per mile in 2025.
How:
- Formula: (Annual Miles / MPG) * Price per Gallon.
- For EVs: (Annual Miles / mi per kWh) * Cost per kWh.
- Use local average prices for the most accurate result.
Done when: You have a total annual fuel/energy budget.
Why: Maintenance costs are rising due to complex tech; the 2025 average is ~11 cents per mile.
How:
- Budget $900/year for basic maintenance (oil, filters, wipers) for newer cars.
- Add $500–$1,000 for older vehicles or luxury brands.
- Include a 'tire fund': (Cost of 4 tires / 50,000 miles) * Annual Miles.
Done when: You have a realistic annual maintenance and repair estimate.
Why: These 'miscellaneous' costs can easily add $500–$1,000 annually in urban areas.
How:
- Estimate monthly parking fees at home/work.
- Review toll tag statements for an annual average.
- Factor in car washes and detailing (e.g., $20/month).
Done when: All minor recurring costs are accounted for.
Why: This single number reveals the true impact of the car on your net worth.
How:
- Sum all categories: Depreciation + Interest + Insurance + Taxes + Fuel + Maintenance + Misc + Opportunity Cost.
- Divide by 12 for the monthly cost.
- Divide by annual miles for the 'Cost per Mile' (2025 average is ~$0.77/mile).
Done when: You have your final TCO and Cost per Mile figures.
Why: Knowing your TCO allows for an objective comparison with other transport modes.
How:
- Compare your monthly TCO against the cost of a public transit pass + occasional car-sharing/Uber.
- If your TCO exceeds $1,000/month, evaluate if a reliable used car or downsizing is more efficient.
Done when: You have a clear comparison of car ownership vs. alternatives.
Why: Small adjustments can save thousands over the ownership cycle.
How:
- Shop for new insurance quotes (safe drivers saw a 2% decrease in late 2025).
- Check tire pressure monthly to improve fuel economy by up to 3%.
- Perform simple DIY tasks like cabin air filter or wiper replacement (saves ~$100/year).
Done when: At least two cost-saving measures are initiated.
