How this service works
Gross margin return on inventory - Base-100 rebase report: Base-100 rebase report for Gross margin return on inventory. Supplied retail figures only. Local calculation and scenario analysis; no live inventory, account access, platform fee lookup or order execution. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded base-100 rebase report deliverable.
Output
Returns a base-100 rebased index series of GMROI values computed from the supplied gross_profit and average_inventory_cost rows, anchored at the specified base_index period (defaulting to period 0). Each period's GMROI is expressed relative to the base period value of 100, enabling trend and scenario comparison across up to 200 retail data rows.
Example use cases
Quarterly GMROI trend benchmarking
“I have 6 quarters of retail data. Gross profits are 4000, 4500, 4800, 5000, 5200, 5500 and average inventory costs are 2000, 2100, 2200, 2300, 2400, 2500. Can you rebase the GMROI series to period 0 and show me the index?”
Seasonal inventory efficiency comparison
“Compare our gross margin return on inventory across 8 monthly periods — gross profits are 3000, 3200, 2800, 3500, 4000, 3800, 4200, 4500 and average inventory costs are 1500, 1600, 1400, 1700, 1800, 1750, 1900, 2000 — rebase it to month 4 as the base period.”
Retail scenario planning for margin changes
“Run a base-100 GMROI rebase analysis for these two retail scenarios: first scenario has gross profit 6000 and average inventory cost 3000, second has gross profit 7000 and inventory cost 3200. I want the index anchored to the first period.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-sector-retail-inventory-margin-return-index?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to normalize a time-series of GMROI figures to a common base-100 index for trend visualization, benchmarking, or scenario analysis using locally supplied retail data — not when you need live inventory data, platform fee lookups, or order execution. Ideal for retail analysts running what-if scenarios or comparing inventory efficiency across periods without needing external data integration.
Side effects
- average_inventory_cost of zero or negative causes division error (field enforces exclusiveMinimum: 0)
- fewer than 2 rows provided returns validation error
- base_index pointing beyond the number of supplied rows causes out-of-bounds error
- extremely large gross_profit values near the ±1 trillion boundary may cause precision issues
- malformed row objects missing required fields (gross_profit or average_inventory_cost) return schema validation errors
