Methodology

Every number should be reproducible.

Calculation

Unit cost equals the displayed package price divided by the labeled number of usable units. Currency values remain unrounded during calculations and are rounded only for display.

Publishing gate

Production offers must be approved, marked high confidence, verified within seven days, and connected to a real retailer URL. Incomplete or stale records are hidden automatically.

Limits

Unit price cannot measure quality, performance, dimensions, or preference. We surface those limits instead of turning a price calculation into a product endorsement.
