From the resale workshop

Leave offer room without inventing a higher value

Turn your minimum acceptable item price into a listing-price constraint, then compare it with your own upper comparable price.

Use the bench in three moves

  1. Check product safety, permitted saleability and actual terms first.
  2. Fill every applicable cost; keep unknown assumptions labelled, not silently zero.
  3. Read the method and exclusions, then change one assumption to test the downside.

Use actual costs or clearly chosen scenarios. Enter zero explicitly where a cost does not apply. Our application does not send or save these entries.

Read the tape

No sale modeled yet. Enter the costs above.

Method and boundaries

Required list price = minimum acceptable item price ÷ (1 − discount/100), rounded UP to the next cent. Buyer shipping and fee terms must stay unchanged from the price-floor calculation. The comparison amount is an input you choose from relevant sold examples, not an appraisal. If the minimum required list exceeds it, reduce planned negotiation room, reduce exposure or pass; do not assume the market will pay your target. Maximum room at your comparison price = max(0, 1 − floor/comparison price) × 100; a zero comparison price has no meaningful ratio. Rounded displays are descriptive, never an automatic acceptance setting.

Worked example · hypothetical, not an actual seller

Negotiation room can conflict with comparisons

Chosen item-price floor $32, planned discount 20%, upper comparable item price $36.

Required asking price $40. That exceeds the entered comparison; a higher cost constraint does not establish higher market value.
