By Hari Vinayak · Updated 2026-06-12
Quick answer
A 2021 Toyota Sienna in good condition with average mileage (about 62,500 miles) is worth roughly $20,450 in a private-party sale — a fair range of $18,800 to $22,100, or about $23,500 at a dealer. 2021 is not on our years-to-avoid list, so condition, history, and maintenance matter more than the model year here.
