Example scenario · illustrative, not a real seller
The $32 offer clears your buy price, but you also promised paid shipping. Rebuild the whole cost floor before replying.
What you’ll get
- A counteroffer constraint that does not invent market value
- A labelled worked example, a visual process and an editable offer-floor scratchpad.
- A device-only action checklist and one next move: Recalculate with the buyer’s actual terms
Above acquisition is not the same as above all costs.
An offer can be above acquisition cost and still lose money. It can also be above a correctly calculated floor but involve terms you should not accept. Separate the arithmetic from the transaction decision before replying.
Build the floor from the whole cost stack
Include acquisition, preparation, packing, paid shipping, applicable fees, relevant overhead and your chosen pre-tax target. Do not mistake the difference between purchase and sale price for profit.
The price-floor planner handles a single percentage on item plus buyer shipping and a fixed charge. Use it only when that model matches the actual official schedule. Tiered fees, shipping exceptions or category-specific structures may need the official-profile calculator or separate work.
Keep the offer’s terms fixed
A lower item price with a new seller-funded shipping request is not the same calculation as a lower item price alone. A bundle changes quantity, packing, weight and potentially per-order fees. Recalculate before agreeing.
Do not save platform fees by moving a marketplace transaction to an unapproved payment route. Follow the applicable rules and confirm payment in your own account. A profitable-looking number does not make an unusual money request legitimate.
What negotiation room actually requires
For an illustrative minimum acceptable item price of $32, leaving room for a chosen 20% offer discount requires a $40 asking price: $32 ÷ 0.80 = $40. These are selected planning inputs, not a claim buyers expect that discount.
If relevant comparisons support an upper item price of only $36, asking $40 does not solve the mismatch. Reduce planned discount room, change costs where legitimate, accept a different target deliberately or pass before acquiring the item. The offer-room tool makes this conflict visible.
Round in the direction the decision needs
A minimum price rounded down can miss the target by a cent. Our minimum-price outputs round upward to the next cent; the actual final fee can still differ with account terms and settlement rounding.
Do not turn a displayed maximum percentage into an automatic offer acceptance threshold. It is rounded descriptive arithmetic, and the transaction can change in ways that a percentage does not capture.
Sometimes a floor is no longer the right objective
After a poor purchase, recovering less than the original target can be a deliberate exit decision. That is different from pretending the first floor was met. Check safety and permitted resale first, then compare the actual cash recovery and storage burden.
Write the reason for an accepted loss in the private item record. Use it to change future sourcing, not to justify buying another item with the same unresolved gap. The goal of the floor is clearer decisions, not an excuse for a price no buyer has demonstrated a willingness to pay.
Worked example · hypothetical, not a real seller
A counteroffer constraint that does not invent market value
A deliberately chosen planning example for this decision. It is not a real transaction, a product appraisal, an observed market result or permission to sell. Replace the inputs only after the relevant checks.
A chosen $40.00 asking price with a 20% discount becomes $32.00. Compare with the chosen $32.00 item-price floor, under unchanged shipping and fee terms. That floor is a cost constraint, not market value or a safe automatic-acceptance setting.
| Measure | Example value |
|---|---|
| Minimum item price ($) | 32 |
| Asking price ($) | 40 |
| Offered item price ($) | 32 |

Should I automatically accept every offer above my calculated floor?
No. The floor is a cost constraint under chosen assumptions, not proof of payment, safety, lawful saleability or suitable terms. Changed shipping, fees, quantity or condition require a new calculation. Rounded percentages are not automatic acceptance settings.
Do this next · one concrete move
Recalculate with the buyer’s actual terms
If quantity, shipping or other charges changed, rebuild the scenario. A rounded descriptive percentage should not become an automatic acceptance rule. Confirm payment and permitted procedure separately.
