Charging the 1 lb label ($9.29) and shipping free differ by $8.55 per order. Free shipping on every order keeps $3.18 per order against $11.73 when shipping is charged. To earn the same per visitor it has to bring 268.9% more buyers. A threshold only adds something above the average order. An order that tops up from $31.06 to $45.19 with more of the same goods and ships free keeps $11.73, against the $11.73 the average order keeps with shipping charged. That is the break-even: a lower threshold loses money on every order that tops up to it, and at $50.00 each top-up earns $2.91 more. Those two orders are costed in the average order's parcel, at the same gross margin; a top-up heavy enough to need a larger label raises the break-even. And every order already above the threshold stops paying its $9.29 of shipping and buys nothing extra. The free-shipping threshold calculator counts both sides with your own order values. ## The cost structure, and where it comes from | | | | --- | --- | | Price | $31.06, the average order.
