    How to interpret true car cost

    This calculator is designed to stop the common mistake of shopping by monthly payment alone. A low payment can hide a long loan term, high insurance, fuel costs, maintenance, sales tax, and depreciation. The better question is what the car is likely to cost over the full ownership period.

    Formula and assumptions

    The estimate combines purchase price, down payment, loan interest, sales tax, insurance, fuel, maintenance, and depreciation over five years. Depreciation is simplified because real resale value depends on make, model, mileage, condition, accident history, and local demand.

    Example

    A $30,000 vehicle may feel affordable if the payment is stretched over a long term, but the five-year cost can climb much higher once interest, fuel, insurance, maintenance, and lost resale value are included. Compare at least two vehicles with the same assumptions before deciding.

    Common mistakes

    • Comparing payment instead of total cost.
    • Forgetting to price insurance before buying.
    • Ignoring depreciation because it is not a monthly bill.

    How to interpret your result

    The five-year cost is the number to compare across vehicles. A car with a slightly higher payment may be cheaper overall if it has lower insurance, better fuel economy, slower depreciation, or fewer expected repairs. The opposite can also be true: a low payment can hide a costly ownership profile.

    What to test next

    Run a conservative version with higher insurance and maintenance, then compare a shorter loan term against a longer one. If the car only works with optimistic assumptions, it is probably too close to the edge of the budget.

    Frequently Asked Questions

    How much does a car really cost per year?
    Beyond the monthly loan payment, car ownership includes gas, insurance, maintenance, registration, and depreciation. The average American spends $12,000-$15,000 per year on vehicle ownership according to AAA - often 2-3x what people expect when they only look at the loan payment.
    How is car depreciation calculated?
    This calculator uses a flat 15% annual depreciation on the purchase price, which approximates the average for new vehicles. New cars typically lose 15-25% of value in year one and 10-15% per year after. Used cars depreciate more slowly. Depreciation is often the single largest cost of car ownership.
    What is included in the true cost of car ownership?
    This calculator includes: loan principal and interest, state sales tax, fuel costs, auto insurance, maintenance and repairs, and depreciation (loss of vehicle value). Registration fees vary too much by state to include but are typically $100-$500/year. Use our loan calculator to compare auto loan terms side-by-side before you buy.
    Is a lower monthly payment always better?
    No. A longer loan term (72 months vs 48 months) lowers your monthly payment but increases total interest paid. A $50/month savings on a 72-month vs 48-month loan can cost $1,000-$2,000 more in total interest depending on your rate. Always compare total cost, not just monthly payment.
