5-Year Cost Breakdown
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.
