The Hidden Cost of Free Shipping
Guide · 2026-10-17
"Free shipping" converts well. It also quietly raises your fee bill, because almost every marketplace charges its percentage on the shipping line whether you charge for it or not.
Two ways to offer it, one is cheaper
Option A: item $30, shipping $0, you pay $5 postage.
Option B: item $35, shipping $0, you pay $5 postage.
Both look identical to the buyer. They are not identical to your fee bill on a platform that charges on item price only, but most charge on the total. On Etsy, the 6.5% transaction fee applies to item plus shipping, so Option A is charged on $30 and Option B on $35.
Where the money goes
Take a $30 item with $5 of postage absorbed by the seller, on a platform charging 6.5% + 3% + $0.25:
- Revenue: $30.00
- Fees: $1.95 + $1.15 = $3.10
- Postage: $5.00
- Product cost: $8.00
- Net: $13.90
Now raise the price to $35 and keep shipping "free":
- Revenue: $35.00
- Fees: $2.28 + $1.30 = $3.58
- Postage: $5.00
- Product cost: $8.00
- Net: $18.42
The extra $5 of price delivered $4.52 of profit, because $0.48 went to fees. Free shipping is not free, it is a fee-bearing price increase.
The threshold trick
Free shipping above a threshold is the strongest version of this: it raises average order value without raising the fee rate. A $50 threshold on a shop with a $28 average order pushes buyers to add a second item, which improves both margin and fee efficiency per dollar.
When free shipping is a mistake
Heavy or bulky products where postage is 25%+ of the price. In that case absorbing shipping destroys the margin and the conversion gain does not compensate. Charge it, and be explicit.
