How the Annual Profit Projection works
Amazon demand is rarely flat. Multiply each month by a seasonality factor (Q4 gifting, summer outdoor, back-to-school) to see where cash and inventory pressure lands.
Formula
- Units(n) = Base × growth^(n−1) × Seasonality(n)
Example
December sells 1.8× an average month, so the Q4 reorder must be placed by August for sea freight.
