Decide what counts as an extra field cost
A returned unit, a remote fix, a replacement shipment and an on-site visit can have different costs. Choose a consistent event definition and use the actual agreement to identify who pays. The budget should capture extra costs, not count the original delivered product again.
Manufacturing.gov’s cost definition includes quality-related and support costs. It does not supply a standard field-return rate, repair price or accounting provision for this product.
Compare 10 and 30 returns without inventing a normal rate
Fictional annual U.S.-dollar model: 500 units sell for US$900 each with US$700 of specified delivery cost per unit. The US$100,000 contribution before further costs excludes any field-return allowance. Assume this U.S. business must fund US$350 replacement goods, US$90 freight and US$160 local work for each event: US$600 extra per return.
| Invented return scenario | Extra cost | Contribution after this extra cost |
|---|---|---|
| 10 of 500 units: 2% | US$6,000 | US$94,000 |
| 30 of 500 units: 6% | US$18,000 | US$82,000 |
The extra 20 events use another US$12,000
The scenario difference is 20 times US$600. These percentages describe only the invented cases; they do not predict your product’s reliability. Management, finance, tax, lost customer orders and other excluded costs still need checking before using a net-profit label.
If your original cost model already includes a return allowance, replace or reconcile that allowance rather than adding the whole new cost on top. If a supplier reimburses part of the cost, check its actual scope and cash timing separately. A reimbursement does not remove the work or necessarily arrive before the bill.
Give management a count and a cost record
Ask for units in use, the observation period, event types, repeat visits, parts, freight, labour and the payer. A few early installations may not yet show a full year’s experience; keep that uncertainty rather than presenting a precise long-term rate.
Use supported annual costs in U.S. unit economics and keep the event log and sensitivity table beside it. The existing repair guide follows one claim’s approval and reimbursement; this budget addresses aggregate exposure. Product-safety concerns need their own response, not just a larger cost allowance.
Scope
- The units, prices, return counts and event costs are fictional. No normal defect rate, warranty entitlement, safety conclusion, accounting provision, insurance coverage or reimbursement promise is established.
Next step
Build a consistent field-event log, calculate the actual extra cost by payer and test several clearly labelled annual scenarios before relying on the offer’s remaining contribution.
