ShopGoodwill max bid calculator

Turn an expected eBay sale, fees, and shipping into a ShopGoodwill max bid that still leaves profit. No login required — then queue the lot in BuzzerBidder with live comps if you want the sniper to fire.

Suggested max bid

$22.60

Net after sale fees & outbound ship: $57.60. Formula: sale × (1 − fee%) − ship out − SGW ship in − target profit. Tax and returns not included.

How to use it

  1. Enter a realistic sold comp (not the listing ask).
  2. Set your fee % (many sellers use ~13% as a rough all-in starting point — adjust).
  3. Add outbound shipping you will charge/pay and inbound ShopGoodwill shipping.
  4. Set the profit you actually need after time and risk.
  5. Use the result as a ceiling in a snipe, not a target to stretch past.
