A used guitar is listed at $800. A buyer offers $720. Shipping charged is $75 and you pay $65. You paid $450 for the guitar and $10 to set it up. Reverb marketplace is entered at 5% of the item, payment at 3.19% + $0.49 on item plus shipping, eBay final value at 13.6% + $0.40 on item plus shipping. These are starting points, not live schedules — overwrite them on the calculator.
| Path | Fees | Net cash |
|---|---|---|
| Reverb at $800 list | $68.40 | $281.60 |
| Reverb at the $720 offer | $61.85 | $208.15 |
| eBay at $800 list | $119.40 | $230.60 |
| eBay at the same $720 offer | $108.52 | $161.48 |
Taking the offer leaves −$73.45 versus waiting for list on Reverb. It still beats selling the same $720 on eBay. It does not beat eBay at your $800 list: eBay list leaves $230.60, and the Reverb offer that matches that cash is $744.45.
So on this example the $720 offer is cheaper than waiting on Reverb and cheaper than taking eBay at list. It is better than matching the lowball on eBay. None of those sentences is advice to accept or refuse — they are the arithmetic on the inputs above.
Marketplace and Reverb Gives apply to the item. Payment processing applies to item plus shipping charged. Change any rate on the calculator and the four paths update. Your numbers stay in the browser. A different question — whether to charge shipping, include it, or offer pickup — is on should I include shipping on Reverb. Comparing this guitar to eBay, Etsy, Amazon, or your own store? The where-to-sell calculator ranks Reverb against them with this item's price, shipping, and cost already filled in.
On the worked example — $800 list, $720 offer, $450 cost, $75/$65 shipping, 5% Reverb marketplace, 3.19%+$0.49 payment, 13.6% eBay final value — the offer leaves $208.15. Waiting for list on Reverb leaves $281.60. The same $800 on eBay leaves $230.60. The offer still beats eBay at $720 ($161.48) but not eBay at list. The Reverb offer that matches eBay list cash is $744.45.
