Depreciation: The Hidden Cost of New

A new car loses roughly 20–30% of its value in the first year and 50%+ in the first five years. This depreciation isn't a fee you pay directly — but it's the biggest financial cost of new car ownership. When you sell or trade in, you get back what the market says it's worth, not what you paid.

A used car has already absorbed that steepest depreciation. The person who bought it new took the hit; you're buying at the post-depreciation price.

The sweet spot: A 2–4 year old used car with 25,000–50,000 miles from a reliable brand. Worst of the depreciation is done; typically still under the manufacturer's powertrain warranty or certified pre-owned program; modern reliability means it likely has many years of service left.

When New Makes Sense

  • You can get a 0% or very low promotional APR through the manufacturer (effectively free financing)
  • You plan to keep the car 8–10+ years (depreciation becomes less relevant)
  • Your credit qualifies you for the best new car rates
  • You need specific features only available new
  • Manufacturer warranty coverage is important to you and the math works

When Used Makes More Sense

  • Your budget is tight — you need a lower monthly payment
  • You want to avoid major depreciation losses if you keep it less than 5 years
  • The specific vehicle you want holds its value well (making new vs. used less dramatic)
  • You're comfortable with some uncertainty in vehicle history

The KCCU Auto Loan Advantage

Credit unions typically offer lower auto loan rates than dealership financing — often 1–2% lower. That difference matters: on a $20,000 loan over 60 months, 1% lower rate saves roughly $600 in total interest. Get pre-approved through KCCU before you go to the dealership — it gives you negotiating power and protects you from high-pressure dealer financing pitches.

Rates, prices, and vehicle values are illustrative and change frequently. Contact KCCU for current auto loan rates and pre-approval options.
