Interactive demo with synthetic data. This environment demonstrates Terra PPC workflows using synthetic advertising, seller-business, financial and economics data. Actions remain inside this demo and are not sent to Amazon or any external advertising or selling account.
COGS History
Every cost version of a product, the cost each day's sales carried, the cost actions in the Change Log and how the current cost reaches automation.
All information shown in this module is synthetic demo data and does not represent a live Amazon selling account.
Current Unit Cost
The landed cost the next unit sold carries — the input of modeled break-even ACoS.$7.06

Effective To is derived: an open-ended sale-date version ends the day before the next version starts. Batch-based costing applies now. Correct opens a new version with the same start date; the corrected version stays here, marked superseded. Purchase layers are corrected by recording a new layer.
Unit cost carried by each day's sales
ASSUMPTION: User-configured assumption. Not provided by Amazon.SELLER: Simulated seller-business context (SP-API-oriented workflow).DERIVED: Calculated by Terra PPC from other values shown.Each day's COGS divided by its units — the cost the day's sales actually carried in the P&L. The dashed line is the cost the next unit sold carries (break-even).
- Unit cost of units sold
- Next unit $7.06
Days without a sale leave a gap: no unit carried a cost that day. Units sold come from the synthetic seller sales series.
How cost reaches automation
ASSUMPTION: User-configured assumption. Not provided by Amazon.ADS: Simulated advertising data (Amazon Ads API-oriented workflow).DERIVED: Calculated by Terra PPC from other values shown.Supplier cost → COGS share of price → modeled break-even ACoS → current ACoS → scale decision → review → audit, computed from the current demo state.
3 enabled campaigns advertise this product; the lead campaign carries most of its ad-attributed sales.
1. Supplier cost
ASSUMPTION: User-configured assumption. Not provided by Amazon.$6.76 → $7.06
Latest change +4.4% (the cost the next unit sold carries). +4.4% within 30 days ($6.76 → $7.06).
2. COGS share of price
ASSUMPTION: User-configured assumption. Not provided by Amazon.DERIVED: Calculated by Terra PPC from other values shown.32.2% → 33.6%
Price $20.99; the landed unit cost takes this share of each sale before fees and advertising.
3. Modeled break-even ACoS
ASSUMPTION: User-configured assumption. Not provided by Amazon.DERIVED: Calculated by Terra PPC from other values shown.48.1% → 48.0%
SP | Brand Defense — Exact: the ACoS at which modeled profit after ads is zero (this product is 4.7% of its ad-attributed sales).
4. Current ACoS (30 days)
ADS: Simulated advertising data (Amazon Ads API-oriented workflow).9.4%
Target ACoS 15.0%.
5. Risk
DERIVED: Calculated by Terra PPC from other values shown.Within target
The campaign still earns a modeled contribution after ads.
6. Scale decision
DERIVED: Calculated by Terra PPC from other values shown.DEMO: Synthetic demo value. No live Amazon connection.Allowed
A budget or bid increase on this campaign passes every business guard.
