Exchange order loss worked example for a size exchange
Last updated: 2026-07-31
Written and reviewed by Seller Profit Guard Editorial Team.
A USD 55 original gross amount less USD 15 product cost, USD 6 outbound shipping, and USD 5 fees leaves USD 29 contribution. The size exchange adds USD 34.50 response cost and recognizes USD 12 returned-inventory recovery, producing USD 22.50 loss and USD 6.50 remaining contribution.
Verify the original packet
Use one medium item sold for USD 50 plus USD 5 buyer shipping with one unit, one currency, and one fulfilled order state. Add the result to the size-exchange calculation worksheet with the packet alias, source version, evidence date, owner, currency, scope, and affected calculation field. This makes a fully traceable size-exchange example reproducible instead of dependent on memory or an unversioned marketplace screen.
Do not use total order revenue if other lines were not exchanged. Review point 1 must state what is observed, what remains an assumption, which authority is outside the calculation, and what evidence would change the result. Keep returned-item, new-item, shipping, fee, payment, refund, inventory, policy, and fulfillment states separate.
Derive USD 29 original contribution
Subtract USD 15 direct product cost, USD 6 original outbound shipping, and USD 5 original fees from USD 55 gross buyer amount. Add the result to the size-exchange calculation worksheet with the packet alias, source version, evidence date, owner, currency, scope, and affected calculation field. This makes a fully traceable size-exchange example reproducible instead of dependent on memory or an unversioned marketplace screen.
Store the unrounded inputs and show the arithmetic before adding exchange cost. Review point 2 must state what is observed, what remains an assumption, which authority is outside the calculation, and what evidence would change the result. Keep returned-item, new-item, shipping, fee, payment, refund, inventory, policy, and fulfillment states separate.
Add USD 6 return shipping
Use the seller-borne final charge for the returned medium item packet. Add the result to the size-exchange calculation worksheet with the packet alias, source version, evidence date, owner, currency, scope, and affected calculation field. This makes a fully traceable size-exchange example reproducible instead of dependent on memory or an unversioned marketplace screen.
An issued but unused label or customer-purchased postage belongs to a different evidence state. Review point 3 must state what is observed, what remains an assumption, which authority is outside the calculation, and what evidence would change the result. Keep returned-item, new-item, shipping, fee, payment, refund, inventory, policy, and fulfillment states separate.
Add USD 15 new-item cost
Use the direct cost of the large item actually selected for fulfillment. Add the result to the size-exchange calculation worksheet with the packet alias, source version, evidence date, owner, currency, scope, and affected calculation field. This makes a fully traceable size-exchange example reproducible instead of dependent on memory or an unversioned marketplace screen.
Equal price does not prove equal material, labor, packaging, or supplier cost. Review point 4 must state what is observed, what remains an assumption, which authority is outside the calculation, and what evidence would change the result. Keep returned-item, new-item, shipping, fee, payment, refund, inventory, policy, and fulfillment states separate.
Add second fulfillment cost
Combine USD 6 exchange outbound shipping, USD 1.50 packaging, USD 5 handling, and USD 1 added fee debit. Add the result to the size-exchange calculation worksheet with the packet alias, source version, evidence date, owner, currency, scope, and affected calculation field. This makes a fully traceable size-exchange example reproducible instead of dependent on memory or an unversioned marketplace screen.
The second parcel is incremental and must not replace the original shipment. Review point 5 must state what is observed, what remains an assumption, which authority is outside the calculation, and what evidence would change the result. Keep returned-item, new-item, shipping, fee, payment, refund, inventory, policy, and fulfillment states separate.
Recognize USD 12 recovery
Use only the inspected returned item's conservative recoverable value. Add the result to the size-exchange calculation worksheet with the packet alias, source version, evidence date, owner, currency, scope, and affected calculation field. This makes a fully traceable size-exchange example reproducible instead of dependent on memory or an unversioned marketplace screen.
Do not enter original retail price, uninspected inventory, or a planned resale amount. Review point 6 must state what is observed, what remains an assumption, which authority is outside the calculation, and what evidence would change the result. Keep returned-item, new-item, shipping, fee, payment, refund, inventory, policy, and fulfillment states separate.
Read the Ready result
USD 22.50 loss is USD 2.50 below the USD 25 maximum and leaves USD 6.50 contribution. Add the result to the size-exchange calculation worksheet with the packet alias, source version, evidence date, owner, currency, scope, and affected calculation field. This makes a fully traceable size-exchange example reproducible instead of dependent on memory or an unversioned marketplace screen.
Ready does not authorize the exchange, reserve stock, collect money, or release fulfillment. Review point 7 must state what is observed, what remains an assumption, which authority is outside the calculation, and what evidence would change the result. Keep returned-item, new-item, shipping, fee, payment, refund, inventory, policy, and fulfillment states separate.
Validate calculation and broken fixtures
Recalculate original contribution, gross response cost, verified recovery, incremental loss, remaining contribution, retention rate, recovery share, and target headroom independently. Test valid size and product exchanges plus blank, NaN, infinite, fractional-quantity, negative, impossible-date, incomplete-confirmation, threshold, refund, credit, mapping, currency, scope, and conflict inputs.
Record full-precision expected values before formatting. A fixture passes only when numeric outputs, masking, Block/Review/Ready state, issue text, reset behavior, browser-local privacy boundary, keyboard path, mobile layout, and correction route all match the declared contract.
Confirm the dated evidence packet for a fully traceable size-exchange example
Require explicit yes confirmations for original-order economics, returned-item receipt and condition, exchange-item inventory and fulfillment, both shipping legs and handling, balance and refund state, fee credit, inventory recovery, source lineage, and planning boundaries. Record a real YYYY-MM-DD source-review date.
A plausible exchange summary without current responsible-owner confirmation is incomplete evidence. Block monetary outputs, name the missing state, and keep buyer, order, label, payment, refund, inventory-location, account, and credential data in authorized systems.
Change returned-item condition
Reduce or remove the USD 12 recovery and recalculate headroom. Deep review 1 for size-exchange calculation worksheet stores the tested input, source state, calculation delta, authority boundary, reviewer, expiry, correction condition, and operational next action. Keep the counterexample even when it does not support the preferred exchange outcome.
Compare the result with the declared a fully traceable size-exchange example, not with a generic benchmark or another packet at a different grain. Explain which single driver moved, which fields stayed constant, what evidence remains unknown, and whether the correct response is collect, correct, review, release, close, or restore.
Change the new size cost
Use the actual large-variant cost rather than assuming parity. Deep review 2 for size-exchange calculation worksheet stores the tested input, source state, calculation delta, authority boundary, reviewer, expiry, correction condition, and operational next action. Keep the counterexample even when it does not support the preferred exchange outcome.

Verify the original packet: verification drill
Recreate “Verify the original packet” from a clean synthetic packet rather than copying the main example. Use one medium item sold for USD 50 plus USD 5 buyer shipping with one unit, one currency, and one fulfilled order state. Change one driver, retain the other fields, calculate the before-and-after difference, and attach the source state and expected outcome to size-exchange calculation worksheet.
Do not use total order revenue if other lines were not exchanged. Drill 1 must include a supported case, a broken case, a late-evidence case, and a correction case. Explain why each path produces Block, Review, Ready, no recognized recovery, or a revised result for this specific a fully traceable size-exchange example.
