How ThriftLens estimates resale range

Transparent methodology — educational estimates, not appraisals.

Sold comps vs active listings

We prioritize recent sold signals where available and treat active listings as context only — asking prices are not realized payouts.

AI is not authentication

Vision models suggest category, condition cues, and comp search terms. They do not certify authenticity for designer, sneakers, or luxury goods.

Fee and shipping assumptions

Profit views use marketplace fee presets and shipping placeholders you can edit. Platform promotions change — verify before listing.

Privacy and data boundaries

Your inventory stays in your account. We do not publish cross-user benchmarks or seller averages in public marketing.
