eBay Best Offer threshold workflow
Use the Best Offer calculator before enabling offers on a fixed-price listing. The useful decision is not a generic percentage of ask; it is the lowest offer that still clears break-even, target profit, target ROI, seller shipping, eBay fee basis, and the per-order fee.
eBay describes Best Offer as a way for buyers and sellers to negotiate fixed-price items, including accepting, declining, countering, and using automatic responses. This tool turns that into seller-ready auto-decline, counter, and auto-accept numbers.
The calculator includes buyer shipping charged and estimated buyer tax because eBay final value fees are based on the total sale amount, not only the item price. That prevents an auto-accept threshold from looking profitable while fee basis quietly erodes the margin.
- Enter list price, buy cost, seller shipping, fee rate, buyer shipping charged, estimated buyer tax, target profit, and ROI floor.
- Copy auto-decline only after verifying it stays below auto-accept.
- Use the stale-inventory mode to accept profitable offers sooner when cash velocity matters.
- Re-run thresholds after markdowns because an old auto-decline floor can block reasonable offers.
Threshold meanings
| Threshold | Decision role | Risk prevented |
|---|---|---|
| Break-even | Lowest offer where profit is zero after fee basis and shipping. | Prevents below-cost accepts. |
| Minimum price | Higher of target-profit floor and target-ROI floor. | Prevents accepting offers that tie up capital for weak return. |
| Auto-decline below | Number that filters low offers before manual review. | Prevents inbox drag and emotional counters. |
| Auto-accept above | Offer level where the deal already meets the floor. | Prevents missing strong offers while away from the listing. |

Frequently Asked Questions
Does enabling eBay Best Offer hurt your profit margin?
Best Offer hurts margin only when thresholds are set below the real profit floor. Calculate break-even after buy cost, seller shipping, eBay final value fee basis, buyer-paid shipping, estimated tax, and the per-order fee. Then set auto-decline below that floor and auto-accept only where your profit and ROI targets are already met.
How do you calculate the right auto-accept threshold for eBay Best Offer?
Start with sold comps and the listing ask, then solve the lowest offer that still clears your target profit and ROI. The calculator uses eBay-style fee basis that includes buyer shipping and estimated tax, so the auto-accept threshold is based on net profit rather than a flat percentage of asking price.
Should every eBay listing have Best Offer turned on?
No. Best Offer fits slow-moving, unique, or negotiable inventory where a profitable offer is better than waiting for full ask. Firm-price listings can still make sense for high-demand items, tight comps, or low-margin flips where negotiation time and accidental below-floor accepts are not worth it.
What auto-accept percentage do most eBay resellers use for Best Offer?
Use a dollar floor before choosing a percentage. A common 85-95% auto-accept range can still lose money when the item has high shipping, high cost, or tax-included fee basis. The safer workflow is to solve the break-even, target-profit, and target-ROI prices first, then compare those dollars with the list-price percentage.
Is eBay Best Offer better than auction format for resellers?
eBay Best Offer on fixed-price listings yields better average sale prices than auction for most resellers working unique thrift or garage sale inventory. Auctions outperform when multiple motivated buyers are competing, but fixed price with Best Offer captures full market value when demand is uneven. Most resellers in 2026 default to fixed-price with Best Offer rather than auction for anything priced above $15.
