How this service works
Unit return rate - Adjacent period changes: Adjacent period changes for Unit return rate. 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 adjacent period changes deliverable.
Output
Returns the computed adjacent period changes for unit return rate across the supplied rows of sold and returned units — showing how the return rate (returned_units / sold_units) shifted between each consecutive period pair.
Example use cases
Quarterly return rate trend review
“I have return data for four quarters: Q1 had 500 units sold and 20 returned, Q2 had 480 sold and 25 returned, Q3 had 510 sold and 18 returned, Q4 had 530 sold and 22 returned. Can you show me how the unit return rate changed between each adjacent quarter?”
Post-promotion return rate impact
“We ran a promotion in month 2. Month 1: 1000 units sold, 40 returned. Month 2: 1500 sold, 90 returned. Month 3: 900 sold, 30 returned. Can you calculate how the return rate shifted between each of those adjacent months?”
Retail scenario analysis for return policy change
“I'm modeling what happens to return rates if we tighten our return policy. Scenario baseline: 200 sold, 30 returned. Scenario 1: 200 sold, 20 returned. Scenario 2: 200 sold, 10 returned. Can you calculate the adjacent period changes in unit return rate across those three scenarios?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-sector-retail-unit-return-period-changes?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, local computation of period-over-period unit return rate changes from raw retail sold/returned figures — no live data access, no account integration required. Ideal for scenario modeling, historical trend analysis, or batch comparisons of up to 200 period rows at $0.01 per call.
Side effects
- Fewer than 2 rows supplied — minimum 2 periods required for adjacent comparison
- sold_units of 0 or missing — division by zero not allowed (exclusiveMinimum enforced)
- More than 200 rows supplied — exceeds maxItems limit
- returned_units exceeds sold_units — may produce return rates above 100%, accepted but may be logically unexpected
- Non-numeric values in rows — schema validation failure
