How to read your results

This calculator compares 5-year total cost: down payment, financing, and maintenance for each option, minus the estimated resale value at year 5 (using the standard depreciation curve where vehicles lose roughly 15-20% in year one and 10-15% per year after that).

The used car has already absorbed its steepest depreciation hit — the first owner ate that cost. This is usually the single biggest factor favoring used over new, even though used cars typically cost more in financing rate and maintenance.

The sweet spot: A car that's 2–3 years old has typically lost 35–45% of its original value but still has most of its useful life remaining and may still have some factory warranty coverage. This is usually the best value point in a vehicle's depreciation curve.

What this calculator doesn't include

  • Certified pre-owned (CPO) premiums — CPO vehicles cost more than standard used but come with extended warranty coverage that can offset higher maintenance estimates.
  • Insurance cost differences — newer cars often cost more to insure; check quotes for both before deciding.
  • Technology and safety features — newer models may have safety features not available on the used version, which has real (if hard to quantify) value.
  • Extended warranty cost — if you're risk-averse about used car reliability, factor in the cost of an extended warranty.

When buying new makes more sense

If you plan to keep the car for 10+ years, want the latest safety technology, or qualify for a 0% promotional financing rate on a new vehicle, buying new can be the better call despite the higher sticker price — the math shifts significantly with 0% financing.
