What this calculator does
New cars depreciate faster. This calculator shows the value of a new car and a used car over 60 months.
The math
New car loses about 1% per month. Used car loses about 0.5% per month. The chart plots both curves.
Worked example
A $35,000 new car may be worth about $19,000 after 5 years. An $18,000 used car may be worth about $13,900.
Why this matters
Big purchases create years of follow-up costs. This calculator helps you weigh the true price before you sign.
Methodology and transparency
This page publishes the exact formula used to compute the result, so you can verify it in a spreadsheet or check the assumptions against your own situation. The worked example uses the tool default inputs; change any number and the result updates live in your browser. No data is sent or stored.
Common questions
Is this exact depreciation?
No. It is a simplified linear approximation. Real depreciation varies by brand and market.
Why does used hold value better?
The steepest depreciation happens in the first few years, which a used car has already experienced.
