Connect ShopifySelf-funding: this threshold pays for its own shipping.
The threshold is a margin decision, not a marketing one
Free shipping is the most abused lever in ecommerce. Set the threshold below your AOV and you're subsidizing shipping on orders you were already getting at full price. Set it too far above and nobody stretches — you just added friction. The right threshold does two jobs at once: it sits high enough above AOV that customers add an item to reach it, and the margin from that added item covers the shipping you give away. This calculator finds both lines and recommends the higher one.
How it's calculated
Break-even threshold = AOV + (shipping cost ÷ gross margin). That's the cart value where the extra margin from the bigger order exactly pays for the shipping you absorb. Example: $60 AOV, 55% margin, $8 shipping → 60 + 8 ÷ 0.55 = $74.55. We also compute the stretch zone — 20–30% above AOV, the range shoppers will realistically reach for — and recommend the higher of the two, rounded to a clean $5 increment. Here that's $75: reachable and self-funding.
When you test a threshold with the slider, we show the extra cart value a customer must add, the extra margin that uplift creates, and what's left after paying shipping. If that final number is positive, the threshold is self-funding and the surplus is profit per qualifying order. If it's negative, you're subsidizing shipping — useful as a conversion lever, but only if enough customers actually reach the bar.
How to read your number
If your break-even threshold lands far above the stretch zone, margins are too thin or shipping too expensive to fund free shipping through bigger carts alone — fix shipping cost or margin first, or restrict free shipping to high-margin products. Once you set a threshold, make it visible: a progress bar in cart ("You're $12 away from free shipping") is what turns the number into behavior. Re-run this whenever AOV or carrier rates move — a threshold set in January quietly goes underwater by Q4. And since free shipping changes your per-order economics, sanity-check your ad targets with the break-even ROAS calculator.
Frequently asked questions
The higher of two numbers: your break-even threshold (AOV + shipping cost ÷ margin) and roughly 20–30% above your current AOV. The first protects margin; the second is the range customers will actually stretch to. Round to a clean number.
Almost always. A threshold below AOV gives free shipping to the majority of orders you'd receive anyway, converting pure margin into a subsidy. Thresholds exist to move behavior, and behavior only moves if the bar sits above where most carts land today.
A visible, reachable threshold reliably pulls a meaningful share of shoppers to add an item — it's one of the most consistent AOV levers in ecommerce. The gains disappear if the threshold is unreachable or invisible, which is why placement (cart progress bar, product page messaging) matters as much as the number.
It can be — for high-margin, low-weight products where shipping is a small percent of AOV, or as a deliberate competitive position. For most stores it's an expensive default. A threshold captures most of the conversion benefit while making larger carts pay for it.
Quarterly, and any time AOV, product mix, or carrier rates change materially. Peak-season carrier surcharges alone can flip a self-funding threshold into a money-loser.
