How Car Comparison Calculation Works

5-Year Cost = Purchase Price + (Annual Fuel Cost × 5) + (Annual Maintenance × 5) + Depreciation

This calculator compares total cost of ownership for two vehicles over 5 years, including purchase price, fuel costs, maintenance expenses, and depreciation. It helps you make informed decisions by looking beyond just the sticker price.

    Include insurance cost differences for a complete comparison

Common Mistakes

  • Comparing only purchase price without considering ongoing costs

  • Underestimating maintenance cost differences between vehicle types

  • Ignoring depreciation which can be $5,000-15,000 over 5 years

  • Using EPA fuel economy instead of real-world figures

FAQs

Why compare 5-year costs instead of just price?

A cheaper car might cost more overall due to worse fuel economy, higher maintenance, or faster depreciation. 5 years captures meaningful ownership costs while most people still own the vehicle.

How accurate are maintenance cost estimates?

Maintenance varies by brand and model. Japanese brands typically cost less to maintain than European luxury brands. Research specific model reliability ratings for better estimates.

Should I include insurance in the comparison?

Yes, if you can get quotes. Insurance varies significantly by vehicle - sports cars and luxury vehicles cost more to insure than sedans and economy cars. This can add thousands over 5 years.

How is depreciation estimated?

The calculator typically uses 50% depreciation over 5 years as an average. Actual depreciation varies - trucks and certain brands hold value better, while luxury cars often depreciate faster.
