How eBay Best Offer Works for Card Sellers
eBay Best Offer lets buyers negotiate. You receive an offer, and you have 48 hours to Accept, Counter, or Decline. The key mistake most sellers make is not knowing their numbers — accepting an offer that sounds reasonable but actually leaves them at a loss after eBay fees.
The rule of thumb: if the offer is above your target ROI, accept. If it's between break-even and target, counter to the midpoint. If it's below break-even, decline or counter firmly to your target price. Never accept below break-even unless you're willing to take a loss to free up capital.
Frequently Asked Questions
How does eBay Best Offer work for sellers?
eBay Best Offer lets buyers submit a price below your listed price. As a seller you can Accept, Counter, or Decline within 48 hours. If you don't respond, the offer expires automatically. You can also set auto-accept and auto-decline thresholds in your listing settings to handle common offers without manual review.
What eBay fees apply when I accept a Best Offer?
When you accept a Best Offer, eBay charges the same Final Value Fee as a regular sale — typically 13.25% for most collectibles categories plus a $0.30 per-order fee. The fee is calculated on the accepted offer price, not your original listed price. Accepting a lower offer reduces your absolute fee but your percentage is the same.
How do I calculate the minimum Best Offer I should accept?
Your break-even offer = (Total Cost + $0.30) ÷ (1 − eBay Fee Rate). If you paid $50 for a card with 13.25% fees: ($50 + $0.30) ÷ (1 − 0.1325) = $58.01. Any offer below this means selling at a loss. This calculator shows your break-even and target automatically.
What is a good profit margin when selling trading cards on eBay?
Most experienced eBay card sellers target 20–30% ROI on raw cards and 30–50% ROI on graded cards, accounting for the risk, time, and costs involved. For high-value cards over $500, even 15–20% ROI can be worthwhile. Set your target ROI in this calculator to see exactly which offers are worth accepting.
Should I counter-offer or decline a low eBay Best Offer?
Counter if the offer is above your break-even but below target ROI — it keeps the buyer engaged and often leads to a deal near your target. Decline only if the offer is below break-even and you're not willing to negotiate lower. Never accept a loss just to make a sale unless it's a strategic decision to free up capital quickly.
