When do luxury sedans depreciate the most in their first year?
Luxury sedans lose the most value in their first year, especially the first three to six months. The biggest hit happens right after you buy it and drive it home. Most drop 20% to 30% in year one. According to Kelley Blue Book's 2025 depreciation analysis, new vehicles lose about 20% or more in the first year, and luxury cars hit harder (Source: KBB Car Depreciation Calculator, 2025).
Here's what you need to know:
| Time in First Year | Typical Depreciation Rate | Value Retained |
|---|---|---|
| First 1-3 months | 15-25% | 75-85% |
| 3-6 months | Additional 5-10% | 65-80% |
| 6-12 months | Additional 5-10% | 55-75% |
"Luxury sedans often shed value fastest in the first year due to high initial demand for new models," says the Sidekick Research Team, based on analysis of 1,200 verified luxury owners (Source: Sidekick Owner Data, Feb 2026).
Why the First Year Hits Hardest
New luxury sedans start with a high sticker price. The moment you drive off the lot, they become used. Dealers mark down new inventory fast. Mileage adds up quick. Many drivers put 1,000 miles in the first month. That alone cuts value by 5-10%.
Market supply plays a role too. Luxury brands release new models yearly. Buyers chase the latest tech and style. This floods the used market with last year's cars. Result: prices plunge.
Sidekick data shows luxury sedans average 25% depreciation in year one (N=850 vehicles). Compare that to mainstream cars at 16-20% (Source: Sidekick Depreciation Tracker, 2026).
Peak Depreciation Windows
- Day 1 to Week 1: Instant 10-15% drop. No one pays new-car price for a used-title sedan.
- Months 1-3: Steepest curve. Average loss hits 20%. High mileage and first service records hurt resale.
- Months 4-6: Curve flattens to 5-8% more. Buyers now see it as a one-year-old car.
After year one, drops slow to 10-15% per year. By year five, many retain just 45-55% original value.
Tips to Minimize First-Year Loss
- Buy certified pre-owned. Skip the new-car penalty.
- Drive under 10,000 miles year one.
- Keep perfect records. Clean Carfax boosts resale 5-10%.
- Sell or trade before month 12. Avoid the one-year mark dip.
