Free Shipping Threshold Optimizer
Plug in your AOV, margin, and shipping cost. We'll show you the threshold sweet spot - high enough to lift basket size, low enough that customers actually clear it.
The 1.5× AOV rule is the sweet spot for most apparel/DTC stores - roughly 30% of orders cross the threshold and each crossing lifts AOV ~12%. Tighter (1.3×) maximizes adoption rate but caps the lift. Looser (1.75×) maximizes margin per crossed cart but converts fewer.
