Car Depreciation Calculator - Future Vehicle Value

For a new mainstream car, 15% for the first 3 years, then 12% for years 4-5, averages about 14% blended and loses 55.6% in 5 years on $40,000 to $17,748. Luxury and EV first-year rates can be 18% to 20%, bringing a $40,000 car to $32,800 or $32,000 after one year versus $34,000 at 15%.

Future value multiplies the current value by (1 − rate) for each year. For $40,000 at 15% for 5 years, value is $40,000×0.85^5 = $17,748. With a $28,900 current value after 2 years, the next 3 years at 15% give $28,900×0.85^3 = $17,748 as well, consistent from either starting point.

No, rates vary by segment. At 15% for 5 years a $40,000 car retains 44.4% ($17,748), while at 12% it retains 52.8% ($21,114) and at 18% it retains 37.1% ($14,848). The $6,266 spread shows you should test 12% and 18% as low-high bounds for your make and fuel type.

Enter a verified current value when you have it, such as a $28,900 listing after 2 years at 15%. The calculator then projects from that $28,900 at the future rate, which is more accurate than re-deriving from $40,000 purchase price and age alone.

Buy a 2- to 3-year-old car after the steepest drop: a $40,000 new car is $28,900 after 2 years at 15% and $24,565 after 3 years, so buying at 2 years avoids $11,100 and at 3 years avoids $15,435 of the 5-year $22,252 loss. Choosing a model with a 12% rate instead of 18% saves $6,266 over 5 years on $40,000.

On $40,000 for 5 years, raising the rate from 15% to 18% drops future value from $17,748 to $14,848, a $2,900 additional loss. Lowering from 15% to 12% raises value to $21,114, a $3,366 gain. A 3-point swing in the assumption matters more than a $2,000 error in purchase price.

This calculator does not include: (1) mileage, trim or accident adjustments beyond what you embed in the current value or rate; (2) regional market demand or fuel-price swings; or (3) taxes, fees or loan interest that affect total ownership cost but not market value itself.

Yes, high mileage lifts the effective rate. A car driven 20,000 miles yearly versus 12,000 averages about 24,000 extra miles over 3 years, often pushing the realized rate from 15% toward 17% to 18%. Enter a $1,500 to $2,500 lower current value to model the mileage penalty directly.

Over 5 years on $40,000 at 15% depreciation, owning loses $22,252 in value while leasing at $450 monthly costs $27,000 with no equity, so owning wins by $4,748 before interest and fees. Adding 5-year loan interest of about $5,500 at 7% makes the two within $700, with leasing ahead only if mileage is under 12,000.

Negative equity occurs when loan balance exceeds market value. On $40,000 financed with $5,000 down at 7% over 60 months, balance after 1 year is about $30,200 while value at 15% is $34,000, so equity is $3,800. After 3 years balance is about $16,500 versus value $24,565, still positive by $8,065.
