Quick answer
How the estimate works
Net profit = sale price + shipping charged − item cost − eBay fees (final value % + per-order) − label cost. Label cost uses the billable-weight model: max(actual, DIM ÷139) through an editable rate table.

Methodology
Formula and assumptions
Net = price + shipping charged − item cost − fees − label. Label from billable weight (DIM ÷139) through editable example rates ($5.85 ≤1 lb, $7.20 ≤2 lb, $9.45 ≤5 lb, $12.60 above — replace with your carrier rates). Fees: final value % on the total amount of the sale + per-order fee.

eBay Shipping Cost Calculator questions
Should I offer free shipping on eBay?
Free shipping improves search visibility (eBay factors it in) but the cost comes out of margin. Model both: set shipping charged to 0 and raise your price, then compare net.
Does eBay charge fees on shipping?
Yes — the final value fee applies to the total amount of the sale, including shipping the buyer pays. The model applies the % to price + shipping charged.
How is this different from the eBay fee calculator?
The eBay fee calculator covers fees in depth; this adds the shipping-label cost side and billable-weight modeling. Use both for the full margin picture.
Worked example: a $40 sale with a $5 shipping charge
Say you sell an item at $40.00, charge the buyer $5.00 for shipping, and your product cost is $18.00. Set the final value fee at 13.25% plus a $0.40 per-order fee, and the label lands in the up-to-2-lb tier at $7.20 (a 14 x 12 x 6 inch box with a 1.5 lb actual weight has a billable weight of 14 x 12 x 6 / 139 = 8.7 rounded up to 9 lb, so that parcel would actually hit the above-5-lb tier at $12.60; this example assumes a lighter 1 lb item).
The total amount of the sale is $45.00, so the fee is 0.1325 x 45.00 = $5.96, plus $0.40, for $6.36. Net = 45.00 - 18.00 - 6.36 - 7.20 = $13.44. Margin on revenue is 13.44 / 45.00 = 29.9%.
Now model free shipping: set shipping charged to 0 and raise the price to $45.00. The fee base is unchanged ($45.00), so fees stay $6.36 and the label is still $7.20, giving the same $13.44 net. That is the structural point: because eBay takes its percentage on price plus shipping charged, a free-shipping repricing that raises the item price by exactly the old shipping charge is net-neutral. Free shipping only pays off if the visibility bump moves conversion enough to beat the price increase you could have kept anyway. Run both scenarios in the calculator with your own fee tier and label rates before deciding.
Boundary cases: where the model bends
At a 0% fee rate (store subscription tiers can approach this on certain categories), net collapses to price + shipping - item cost - label, so the $40 + $5 example above nets 45.00 - 18.00 - 7.20 = $19.80 instead of $13.44. The fee percentage is the single most leveraged input; a 1 point change in it moves net by $0.45 on this sale.
At zero item cost (you sourced the item for nothing, or you are shipping something you already owned), net is just revenue minus fees minus label: 45.00 - 6.36 - 7.20 = $31.44. Watch the opposite direction too: an item cost of $40.00 on the same sale gives 13.44 - 22.00 = a negative $8.56 net, and the calculator will show a loss even though the sale itself completed. Negative nets are the boundary that matters most when clearing out inventory.
Two things the model deliberately does not carry: per-transaction payment processing costs are folded into the per-order fee constant, and promotional credits, top-rated seller discounts, and international surcharges are not modeled. If you run a 10% off coupon funded by you, the fee base drops with the price, but your net drops by roughly 10 cents on every dollar of discount plus the fee it carried. Confirm the label tier with your actual carrier rate card; the $5.85 / $7.20 / $9.45 / $12.60 defaults are placeholders, and a heavy or oversized parcel jumps tiers quickly because DIM weight rounds up at every fractional pound.
