How Boat Trailers Depreciate
- Boat trailers depreciate more slowly than boats:
- Year 1–2: 10–15% loss
- Year 3–5: 20–25% total loss
- Year 6–10: 35–45% total loss
- Year 10–15: 45–55% total loss
- 15+ years: 55–70% total loss
Well-maintained trailers, especially galvanized or aluminum, can retain 40–50% of value after 10–15 years.
