See whether Authenticity Guarantee still pays after the hub label.
Authenticity Guarantee is not the same decision as a return rate or a
partial refund. You pay a typed authenticity fee and often an extra
label to the hub. You usually sell more of the listing and see fewer
“not authentic” returns. The table keeps the original sale, then
subtracts the fee and the hub label and multiplies by sell-through.

The authenticity fee is treated like a percentage marketplace fee and comes back on a return. The extra hub label does not. Transparent arithmetic from your inputs — not eBay’s Authenticity Guarantee policy.
What this checks
Resellers search “is eBay Authenticity Guarantee worth it” because
the badge looks free and the hub label is easy to forget. A 3% fee
plus $8.00 to the authenticator can wipe the conversion lift on a
$40 sneaker even when sell-through jumps from 55% to 80%.
On the defaults — $40 item, $6 shipping charged, 13.6% final value
fee, $0.40 fixed, $12 cost, $5 outbound, $1 pack, $5 return label,
10% returns without AG, 3% authenticity fee, $8 extra hub shipping,
55% vs 80% sell-through, 4% AG return rate — skip-AG expects $9.96
and Authenticity expects $8.72. Authenticity keeps $1.24 less
(−$1.24) on this listing and −$9.93 across eight listings. Extra
hub shipping has to fall to about $6.45 before Authenticity matches.
Set extra hub shipping to $0.00 (a prepaid label) and Authenticity
expects $15.12 — $5.16 more. Raise the without-AG return rate to
25% and Authenticity wins even with the $8 label.
Authenticity Guarantee adds a typed fee and often an extra label to the hub. It usually raises sell-through and lowers authenticity-claim returns. On the calculator defaults ($40 item, $6 shipping, 13.6% final value fee, $12 cost, $5 outbound, 10% returns without AG, 3% authenticity fee, $8 extra hub shipping, 55% vs 80% sell-through, 4% AG return rate) skip-AG expects $9.96 and Authenticity expects $8.72. Extra hub shipping has to fall to about $6.45 before Authenticity matches. That is arithmetic on your inputs, not advice to enroll or skip.
When does eBay Authenticity Guarantee beat skip-AG?
When the extra hub label is prepaid or cheap, or when skip-AG authenticity claims are high. On the same defaults a $0 hub label flips Authenticity ahead by $5.16 per listing ($15.12 vs $9.96). A 25% without-AG return rate also flips Authenticity ahead even with the $8 label.
Does the Authenticity Guarantee fee come back on a return?
This page treats the authenticity fee like a percentage marketplace fee that comes back on a return. The extra hub label does not. Enter the rates from your last payout; this is not eBay’s live Authenticity Guarantee schedule.
